Pay for Module Replacement or Change cells

 

Benefits: It's Cheap!(on paper)

​

In theory, it’s achievable, but in practice, it's far from the optimal route. Let’s break down the proper repair procedure:

​

  1. Battery Pack Uninstallation: 20-90 minutes depending on the model.

  2. Battery Pack Disassembly: 15-45 minutes, depending on the model.

  3. Mapping All Modules’ State of Health: At least 1 hour, depending on the method and equipment.

  4. Rejuvenating Usable Modules: 6-18 hours, depending on the method and equipment.

  5. Battery Modules Cooling Period: 12-24 hours, depending on the environment and method.

  6. Matching and Balancing with Donor Modules: Up to 2 hours, depending on the method and equipment.

  7. Battery Pack Assembly: 20-40 minutes, depending on the model.

  8. Battery Pack Installation: 30-90 minutes, depending on the model.

​

Add up all the labor hours, then factor in the number of modules that need replacing, and it’s clear this isn’t cheap—especially when you consider the wait time involved. So, why are so many cheap repair out there? 

Simple: corners are cut to save time. 

​​

But there's a 6-month or even 1-year warranty for these repair? How’s that possible?

The hidden cost here is the ongoing failure risk. On paper, it’s a bargain—pay a fraction of the cost for a full battery replacement, and you get a year of coverage. In practice, though, you’re going to run into repeated failures. Every time your battery fails within the warranty period, you’re back in the shop, and you’re stuck with that downtime. For commercial drivers, this is especially disastrous—imagine how much money you lose when your livelihood is put on hold. And Good luck after the warranty expires.

​

Think about the lifespan of the original battery. You paid 1/3 of the price for the repair—did you really get 1/3 of the original battery’s life?

​

Conclusion: It's a choice between upfront expense and potential risks and the decision boils down to being informed. And now you  know what you’re getting into. Surely If you get lucky and find someone who does the repair the right way or when they get lucky. Great, congratulations to you. If not, you’re stuck with the consequences.
