How do I fix a bad battery pack?
First, you need to figure out what's wrong with the pack—either bad cells or a wonky Battery Management System (BMS). If it's the BMS, just swap it out with a new one. The BMS keeps an eye on the battery pack's performance and makes sure everything's working within safe limits. Replace the bad BMS, and your battery pack should be good to go.
How do you know if a battery is bad?
Another thing you can do is feel the battery to see if any particular spot is producing more heat than other areas of the battery pack. If after doing those things you feel like your battery might be bad, then you will have to tear it down enough to be able to measure the voltage of each cell group.
Should I replace a bad battery pack?
If it's the BMS, just swap it out with a new one. The BMS keeps an eye on the battery pack's performance and makes sure everything's working within safe limits. Replace the bad BMS, and your battery pack should be good to go. If you've got bad cells, though, you'll need to swap them with matched cells.
Does a battery pack go bad?
Yes! When a battery pack 'goes bad' it's usually because the BMS has decided to shut it off for one of many reasons. This is why it’s a good idea to disassemble lithium-ion battery packs for its cells. In most other cases, just a single cell has failed. Remember, battery packs are made of many cells that are grouped in a specific way.
How do I get a new battery pack?
The simplest solution is to visit the equipment manufacturer’s website to see if a replacement battery pack is available. Sometimes there isn’t and, when there is, the prices can come as a shock. In my case, the equipment worked just fine and looked to have a good few more years of life in it — a new battery would suffice.
How do I know if my car battery is broken?
