EP 3. 1st & 2nd Generation Aftermarket Steel Prismatic 7.2V NiMH Hybrid Battery Casing in Different colors
Technically speaking, the first generation of Steel Prismatic hybrid batteries wasn't available on the market when it was developed in 2018. Instead, the initial batch was sent out from the factory for road testing. We equipped the first (or possibly second) set of 28-piece, 7.2V batteries into a Singapore-registered Toyota Prius. Similarly, the first set of 9.6V batteries was installed in a Singapore-registered Lexus RX400h. I can confidently confirm this, as the second serial-numbered battery, which was found defective, is still kept in my battery testing lab. Unlike the current models, which have serial numbers engraved directly onto the battery, this first batch had labels affixed instead. However, let's turn our focus to the first and second generations of these batteries that were actually released to the market.
严格来说，第一代钢制棱柱混合电池在2018年并未投放市场。相反，首批电池是从工厂发出的，用于道路测试。我们将第一批（或可能是第二批）28片7.2V电池组安装在一辆新加坡注册的丰田普锐斯上。同样，第一批9.6V电池组被安装在一辆新加坡注册的雷克萨斯RX400h上。我可以肯定这一点，因为编号为2的电池被发现有缺陷，目前仍然保存在我的电池测试实验室里。与现在的型号不同，首批电池的序列号是贴在电池上的，而不是像现在这样刻在电池上。不过，让我们把注意力集中在已经上市的第一代和第二代电池上
Photo 1: The first generation of Steel Prismatic 7.2V NiMH batteries began selling in the market in 2019. As shown, the gray casing lacks a hole for the temperature sensor to be inserted. During installation, the car's original temperature sensor was secured to the casing with a cable tie. We closely monitored the battery's performance during driving and reported back to the factory. Our feedback highlighted a concern: if the temperature sensor is obstructed by the plastic casing, the Battery Management System (BMS) might not accurately detect the battery's temperature, potentially leading to battery damage due to overheating. During this period, no other color casing was produced, as other hybrid battery exporters and online marketing companies were still focused on the lower-cost cylindrical battery.

Photo 2: This is the 2nd generation of the Steel Prismatic 7.2V NiMH battery. As shown, the plastic casing now includes a hole for the temperature sensor, allowing direct contact with the steel battery body. Starting from this generation, around 2021, cylindrical batteries began to encounter issues in warm climates. As a result, several battery exporters and online marketing companies gradually transitioned from cylindrical to steel prismatic batteries due to the high number of warranty claims.
We are the official sole distributor for the Singapore and Malaysia markets, but unfortunately, some batteries were still imported into Malaysia through parallel imports. I believe some local workshops imported and sold these batteries in the Malaysian market and are now facing warranty claim issues with exporters based in China. However, if you’re currently dealing with warranty claims—regardless of the casing color or where you purchased the battery—you can always reach out to JIV Battery. As the Steel Prismatic battery sole distributor from the battery factory, I am confident that I can resolve your warranty claim issues, provided they aren’t due to human error from incorrect installation.
During this period, some lower-capacity steel prismatic batteries were also manufactured to meet the low-cost demands of certain exporters, particularly those from online marketing companies, aiming to compete with cylindrical batteries. Let's discuss the battery design and actual capacity in future episodes.
照片2： 这是第二代钢制棱柱7.2V镍氢电池。如图所示，塑料外壳上现在有一个孔用于插入温度传感器，使其能够直接接触到钢制电池体。从这一代开始，大约在2021年，圆柱形电池在温暖气候下开始出现问题。因此，一些电池出口商和在线营销公司逐渐将产品从圆柱形电池转向钢制棱柱电池，以应对高频次的保修索赔。
我们是新加坡和马来西亚市场的官方唯一分销商，但不幸的是，一些电池仍然通过平行进口进入马来西亚。我相信一些当地车间进口并销售了这些电池，当前面临来自中国出口商的保修索赔问题。不过，如果您目前面临保修索赔问题，无论电池的外壳颜色或购买地点如何，您都可以随时联系JIVBattery。作为电池工厂的唯一分销商，我有信心可以解决您的保修索赔问题，只要不是由于安装不当的人为错误导致的。
在此期间，一些低容量的钢制棱柱电池也被制造出来，以满足某些出口商特别是在线营销公司对低成本的要求，旨在与圆柱形电池竞争。我们将在未来的章节中讨论电池设计和实际容量问题
Photo 3 & 4: The 2nd generation Steel Prismatic 7.2V NiMH batteries are shown in different colors of casings. These varied colors are requested by some local dealers, exporters, and online marketing companies in China. A wide range of casing colors can be found in the market. For higher-volume customers, the factory allows them to select their preferred color based on customer demands. Here, "customer" refers to the battery factory's clients, including exporters and online marketing companies.

In the next post, we will discuss 3rd and 4th generation of aftermarket steel prismatic 7.2V NiMH hybrid batteries. Stay tuned !
在下一篇帖子中，我们将讨论第三代和第四代市场后备钢制棱柱7.2V镍氢混合动力电池。敬请关注！
