Another day, another completely unresponsive car.

This may or may not completely be an issue. But it is a contributing factor, we are quite sure.

Whenever you leave a car parked to go overseas, it is always advisable to check that all lights are off, recording camera is also off (or at least unplugged if it is set to 24hrs recording), but how do you disconnect the OBU on your own without the help of a technician? Erm, we can’t advise on that.

So, it’s easy to conclude this car is completely dead beacuase the car was unresponsive to the remote car key. We know the remote car key is still working for two reasons, one, it has that flashing little red light when you press on the button. Two, it worked like it should after the main car battery was replaced.

And if you are wondering how does a car with an electric boot open without any electrical power? Hint: for most German/continental makes, there is a jump start point in the front engine compartment that allows us to connect an external source of power.

This is also a handy point to back up power to the car while the car battery is being replaced. Having this power hooked up allows us to use the electrically operated boot and have access to the main car battery.

More than once, we were told by owners of continental cars which we were called in to change that “hey, the battery is in the boot!” when we opened the front bonnet. (Not this case though, because we fixed the car while the owner was still flying back Singapore)

This particular Audi A6 was parked for three weeks, and before the owner returned to Singapore, was already told by his family that the car was totally not responding to the remote. We are quite certain that without the OBU, the car would still unlock, because the power to unlock a car, as mentioned in our previous post, is very much less than that required to crank start a large capacity engine. But this one did not unlock.

Using the physical key, we unlocked the car and the dashboard that usually has some indication of life was also totally black.

Immediately after connecting the external power, the dash came to life.

The A6 car battery is under the floorboard of the boot and from what we saw, we concluded this unimportant and non-technical fact… the owner plays golf because there is a lot of dried grass in the boot! Back to the main story…

A typical A6 uses the 95Ah battery capacity with 760A EN of cranking power. We gave a little upgrade by installing one from Hoppecke Premium that is 100Ah. A little more is always nice to have, isn’t it?

The rest was fairly straightforward, with the removal of the old and installation and securing of the new one, the car was ready to be tested for starting up and alternator function. This is an important step as it helps to rule out the fact the old battery did not fail due to insufficient charging from a weak and failing alternator.

Fault codes were cleared by our programming tool so the customer would not have a face full of weird symbols which are recorded errors due to the sensors detecting low voltage levels, and we are done.

Happy to recover this handsome vehicle, and very satisfying to hear the engine roar back to life first crank after a new battery is installed!

I guess we are not the only ones who are 𝖓𝖔𝖙 fans of the new .

This has been discussed ad nauseum on social media posts about how a supposedly more advanced items is now three pieces instead of one, and operates hot (this means high electrical current draw).

Car owners have reported OBU issues ranging from slow OBU boot-up after engine start (still not functioning even after car has reached home gantry for exit), non-detection of a successfully powered on OBU at home HDB parking gantry, to OBU becoming inoperable after a long holiday overseas when the car was parked for extended periods and requiring repair by the OBU installer. Inconvenient, and another trip to the installer.

And of course, the most common problem we as a battery service get called into handle. A totally dead car, where it would not even unlock in the morning using the remote.

There are instances where the OBU will draw on the car battery more gradually and that results in a weak battery for cars that do not drive daily. This can be expected because we believe the OBU is designed to still work when the car is switched off and parked.

Then there are also those who are so dead that the physical car key is needed to be able to open the door to get into the car, which naturally means it also would not start.

Why? Because only a fraction of the power is needed to unlock the car, compared to the amount of power the starter motor draws when it needs to crank the engine.

How do we know it is not a car battery fault or that battery is just old?
1. When an old battery is too weak to start the car, it can still unlock the car using the car remote.
2. The measured voltage will be 11+v to 12+v but the CCA measured will be too low to start the car.
A battery that is drained till the remote does not even work is typically at or below 5v. 5v is what most electronics need to work.
It is almost for certain that any voltage below 9v is a sign that there is power use from the car while it was stationary and parked, or the alternator has failed.

Back to the OBU story. We have had three cases in recent succession that are highly suspect of due to OBU.
The three models we had help are from Honda (Civic Hybrid), Hyundai (Elantra) and Toyota (newish Sienta)

No, it is not always the fault of the engineering design of the OBU, but sometimes the installation workmanship of the OBU is also suspect.

The place where power is tapped from the car circuitry (which by the way is not natively designed to power an OBU) can be a bit sus if the installer has never encountered your brand and model of car before. So owners of rarer car models…

Even the mainstream dealerships installed OBU are a bit, how shall we say, less professional that we have expected them to be? Refer to pictures of messy wires jumbled together. We found this “bad hair day” bunch of wiring blocking the way when we tried to find the OBD port!

If you have just had your OBU installed and the battery has failed (car dead) within a month of it being installed, then there is a possibility it may be caused by the OBU install or an OBU problem.

The wiring may need to be rechecked, or the OBU unit itself may have some faults causing high current drain.

See chat we had with Hyundai owner. The Elantra was so low on power, he had to use the physical key to open the doors. Car jump start worked, so there is nothing wrong with the engine, fuel pump or starter motor. However, after starting we noticed that the radio display is showing wrong date and time (sign of super low battery caused by power drain erasing the memory of the radio), and the display unit of the OBU did not start up.

Owner went for a new battery while we were there and post battery replacement, drove down to the authorised distributor who had installed the OBU. They replaced the fuse on the OBU, which had blown.

Fuse replacement is a sign of high current draw (see AI explanation) and this high current was taken by the OBU since it is the OBU fuse that was replaced. Why did the OBU draw such a high current so as to blow the fuse? Is the OBU unit faulty?

Replacement of the fuse does not solve the root cause. Should this problem recur, it would likely mean this particular OBU has a problem and the set itself should be replaced, not the fuse.

Have you heard of the term depth of discharge before (DoD)?

That is the amount of power remaining in a battery and the lower the amount, the greater it has been discharged.

FACT 1: Most car use maintenance free sealed or VRLA batteries, some of which have AGM (absorbent glass mat) in them to prevent acid spills and to enhance power output.

FACT 2: Most battery chemistries, including our common lead acid and also colloidal gel types (not usually used in cars), have shortened lifespan when they are discharged deeply.

FACT 3: If discharged to a low state, immediate recharging helps, but still they will suffer a shorter lifespan.

FACT 4: Leaving a battery in a low state of charge further damages it. In fact, it can be so damaged that it does not recover from it even when recharged and so is no longer reliable to start your car

So, knowing the above, do you know what constitutes a low level of charge for your car battery?

See the below table.

A healthy level of charge would be 12.42 or above for a standard maintenance free battery.

Many car owners running their 24 hour recording car cameras with the starter battery are unaware that they are damaging their car batteries if they do not have battery pack that is dedicated to power the camera only!

FACT 5: Did you know that setting a voltage to cut off the recording can help but still uses power after the camera goes into standby?

In the pictures you can also see a rather new Amaron battery here that was taken out and replaced.

But why? Stay tuned to our next post!

Do you have car problems? This is an exhibition of car problems!

Listen to the end, where a solution for lithium fire is also mentioned.

And that's why we don't sell lithium starter batteries.

It is a modification not covered by insurance if your car did not come with lithium batteries in the first place.

There is a non-zero chance it is going to have thermal runaway, after which stopping it is near impossible if you only have your water bottle.

Is it worth it when it does nothing much more than what a standard battery can do?

We posted quite a few of the difficult battery replacement jobs that we did and… kinda regret it! Because we get called for those more often, haha!

Well this is a straightforward one, we did a Hyundai Avante! Yay!

Our customer Ms. P from Ang Mo Kio has been our long-time customer.

Why long?

Because the last battery we installed lasted a good long time. And it was the first one her car has needed since it was registered. Thanks to Ms. P for trusting the batteries we recommend.

Amaron, lasts a long time yes?

And this time we are doing an upgrade for her, to let it last even longer!

The previous battery was sized the same as when it left the Hyundai factory, which is a pretty small one rated at 45Ah.

Did you know? There is space in many cars to upgrade the battery to one or two sizes up.

So this time, we installed a larger 66Ah battery for her.

For those not accustomed to looking at battery specifications, this is one of the most basic specs you look at, to know if you are getting something comparable for the price.

It is often that when calling around, you will get a cheaper quote, but with that lower price comes a poorer brand battery and smaller capacity.

We did this for fun for this old customer, and she got a bigger one for the same price.

Why? Just to experiment and prove a point.

A bigger capacity battery with higher Ah and CCA rating will last for longer.

Her old 45Ah Amaron Pro lasted 2 years and 6 months. Let’s see how this works out for this one rated at 66Ah.

Don’t hold your breath!

It is alright to use any electrical accessories, when the engine is running.

Even if using them all at once, its OK!

That's because while the engine runs, it supplies power via the alternator to power the lights, radio, aircon, and so on.

But when it is parked, that's when running anything that requires electricity comes from vehicle battery.

Even a small electrical usage can result in a lot of power used up if left on for extended periods, In this case, it has been over 48 hours since it was last driven.

The boss here is a kind man that always uses our service, and sadly for him, a diesel lorry is very difficult to jump start.

It just might be possible if the flat battery still had 10 or 11V.

But one that has only 0.9V left on the battery, we had little choice but to propose a change of battery so it could be restarted.

It's always the small things that causes this big inconvenience. Something small that is left running when parked.

A little effort and care can save a lot of headache. Especially if rushing for work.

We sent the boss two videos of what we saw as a possible cause. Later on, as we worked, we found a high chance of what the actual cause was.

And be careful next time, because a totally drained battery, even relatively new, becomes deteriorated when the battery is discharged.

Find out more what happens when the battery we removed from here was recharged back at our office. Trying to save our boss a little bit…

Will add a link in below comments.

It’s natural for first time customers to have apprehension about the advice we give.

Afterall, they don’t want to incur the cost of onsite diagnostics for your car (battery and charging system) if it’s not a problem with the car battery. And that we understand.
But help us to help you and we can do a remote assessment, for free.

Just like this lady and her husband Mr D, they sent us a video of what happens when their car cannot start.

With the video, it will give us more information about the behaviour of your vehicle when you are trying to start it, which will have many clues to help us determine, with up to 95% accuracy, if indeed it is the battery or not.

•⁠ ⁠What does the dashboard look like when trying to start?

•⁠ ⁠Does the car crank at all?

We not only look at the video but also have to listen to the sounds in the background to assess. (So do let your phone record those sounds too, e,g,: with car door open helps to hear the sounds of cranking)

Mr and Mrs D’s BMW 2 was parked at Woodlands under their office block. But end of the day, she couldn’t go home because the car would not start.

And the display was showing these messages: “Increased battery discharge when stationary”
Ironically, the car asked to be started when it could not.
So Fastfixer to the recue!

And because of her video, we went down to the car with a high chance of certainty that the car battery was the fault.

With a brand new Hoppecke Premium German brand battery for a German car installed, it started without hiccups and we had happy relieved smiles all around!

Thank you Mr & Mrs D for choosing .

The cleanest and most shiny car we attended to that can't start!

No wonder, he says he just did the car polishing! And he did it himself because he just attended a car detailing course.

We are impressed!😮

And so, we set to make the car even better, with a new battery! 💪

Before we start, we connected the back up power supply, as you can see, to the driver's side footwell. This extra effort prevents total power loss and keeps your car clock and radio stations in the memory so they won't be lost.

Mr Fadhli, extra curious, asked what we did on the driver's side while we were working on taking out the old battery.

We told him we want to prevent memory loss from his car, and keep the clock running at the correct time so it need not be reset.

His reply had us both laughing: "Then I think lost already lah! Just now trying to start the car, the radio display already asked me to select which language I want..." 🤣

If the battery is too weak, yes, we can't save the situation because the memory is already lost before we reach the car.

And it was lost when Mr Fadhli tried to crank start, because that draws the most power, compared to just lighting up the dashboard or radio screen.

Which explains why many cars' have a blackout of the dash or flickering lights when trying to start with a weak battery.

See https://www.fastfix.com.sg/top-5-reasons-why-car-cant-start/ for more video examples of how to identify if it is a battery issues. All videos there were kindly sent to us by our customers requesting for help 😊 so we can assist a bit to identify remotely.

It always makes us happy to help out someone in need!

Mr Colin here was very glad to have us reach him within the hour so he could go out after replacement was done. His smile was our bonus reward!

Sometimes we make mistakes in our quote, and customers like him are very much appreciated! This Sylphy here is a 1.6L but uses a battery size 26L that is usually for 2L cars such as the Harrier.

1.6L Japanese cars typically use a 23L, such as for the Lancer. And Civics often use an even smaller battery such as the 24L (yes I know, bigger model number but the physical dimensions is actually smaller! Don't ask me why!)

Anyway, Mr. Colin here was quick to forgive our wrong quote, and accepted the higher price that came with a bigger battery. Our apologies and thanks to him for being understanding!

His old battery also lasted a pretty short time, so we are a bit concerned as to why that is the case.

His workshop that fitted it also gave a better version of the 26L of this other brand Varta, the EFB type 26L too, but still... And EFB battery is longer lasting and built to withstand the greater demands of a start stop vehicle. A start stop car stops the engine at the traffic lights and then restarts before moving off again, to save fuel.

But what you save in fuel, you also demand of the battery, because the car runs its aircon fan, headlights and radio off of the battery only when the engine is stopped.

So, despite the better battery, it didn't start the engine, not long after it was last replaced (June 2023).

We had to run a complete test of his car, and make sure the alternator was doing a good job of the charging. Sometimes it is not the battery fault, it is the alternator that does not charge well which creates a weak battery!

New battery fitted and the car started without problems; his alternator was going at 14v + which is a good reading. The alternator needs to be at 13.8v (recommended) or more, while the aircon and headlights are on, in order to charge the battery well.

Cranking was good too, and voltage remained acceptably high while cranking! All was well with the car battery and starter systems then!

So what else can cause early battery failure? Leaving electronics running or forgetting to switch off the hazard lights or ceiling lights can drain a battery and cause its lifespan to be depleted early. So always remember to switch things off when leaving your car parked and especially so if leaving Singapore for a holiday!

Wish you happy driving Mr. Colin! And a long battery life!

Phone rings…📱

Caller: Hi, you do battery change right?

Fastfixer: Yes, that’s what we do!

Caller: My car cannot start, you can come over for the battery change?

Fastfixer: Yes, we can do that. Where are you and what car do you driver?

Caller: My car is a 🚙 and I am in Ang Mo Kio.

Fastfixer: Which year of registration please?

Caller: 2012.

Fastfixer: Ok, so that means non start-stop vehicle.

Caller: What is start stop? Oh I know. No the car engine does not switch off at the red lights.

Fastfixer: For your model, non-start stop vehicle, battery inclusive of the transport and labour to fit the price is $###. No further taxes.

Caller: Wah so expensive? Got cheaper?

Fastfixer: We have two brands in the *recommended size* for your car. The price is $xx less if you choose to use the lower cost brand.

Caller (already made up his mind): I think about it, call you back.

The Caller does not call back. He goes to call many others to find the lowest price possible. That’s not something that we would say is wrong, but going about it without knowledge is just asking to be scammed.

If you ask enough people, you soon find a not too honest one giving a “discount”.

Caller finds a cheaper battery at $20 off the price we quoted. “Hey, it’s fitted and the car can start can already!! Hurray!” Or so he thinks.

Because, it doesn't last as long!

When you buy a battery, you want it to last the price you paid. So what if Caller got a 10% discount of the price, but a 25% “discount” of the lifespan of the battery?

Typically, for cars in Singapore fitted with the correct type and spec, the battery life is about 2+ years.

Minus $20 (for small car batteries) for minus 5-6 months of lifespan?

Caller just got scammed. These pictures here of two Honda Fit/Jazz we did are proof of one of the common ways car owners get scammed into thinking a more expensive option is the cheaper one!

To be clear: these two owners did not ask for cheaper. (Our customers are not cheapskates).

They just didn’t know and were given the lower spec, undersized items so the seller can maximise profits.

If they did ask for cheaper, the seller can afford to and they would be offered $10-20 off, but the seller would still be laughing after the deal.
