    You should measure the voltage of all 5 cell groups in the battery before doing anything. This will indicate if this battery is worth salvaging, or serve as a cell donor. Don't start working on replacing the first group, to later find out that two other groups are bad. To optimize this battery's capacity, you should also balance the cells in the battery. All of them should read the same voltage. When the battery is in use, the thing will stop powering your tool as soon as the first cell is depleted. When the battery is on charging, the charger will stop as soon as the first cell gets full. No matter the state of charge of the other cells. A good Li-ion battery has a load-balancing circuit for its cells. Tool batteries usually only have protection, so the manufacturer gets to sell more of them.

      Yeah even I say no to some I had 2 makita batteries sent to me one was beyond repair the circuit board needed replacing and the cells were all beyond recovery I would have needed to build a full battery. I decided with time components and materials it wasn't worth it. I do however get a kick out of getting a tool working again even in a suboptimal way. If I think it's cost effective to do it I will.

Recently tried getting ripped off by a DeWalt repair centre I think they were overpricing repairs so you asked to scrap the tool then keeping the tool and repairing for profit. They quoted me more than the value of the tool on 6 of my tools which had the common switch fault on DeWalt anyway I repaired them all for free with the contact cleaner trigger repair. Another was a simple chuck replacement on drill (easy chuck replacement without taking the whole housing apart) I removed the chuck and waiting on a £20 replacement. They quoted me £150 for a £100 drill
