Replace a module or not replace a module; that is a question many Prius owners are asking. In a recent video that I did with YouTube superstar Toyotajeff, we covered a few hot questions asked frequently by Toyota Prius owners.
I want to cover one basic principle in this article: what to do about a failed module in your hybrid battery pack.
Can I Replace One Module In My Failed Battery Pack?
The short answer to this question is yes, you can. However, you may not want to, depending on a couple of things. If you plan to keep the Prius for a long time, a simple module replacement is hardly a band-aid solution.
Replacing one failed module can work, but it will not last. Most people that do replace a failed module without properly rebalancing the battery end up tearing back into the pack over and over again. I see that happen all the time.
Think about it, have you ever had a flashlight that you only replaced 1 of the 3 batteries? Did it work? Sometimes it does, but not for long. When you have a battery trying to compensate for the others, you end up in a losing game.
If you want to keep your Prius, a certified replacement pack or a new pack is the better option. I have rebuilt and reconditioned plenty of packs now to know what the better way.
