Since the packs need replacing after about 18 to 24 months, and you may even see decreased performance before that, rebuilding your battery power pack is a cheaper option than discarding it and buying a new one.
Battery power packs for drills and other types of tools are made using individual battery cells that are wired in a series.
If you wire battery cells in a series, you combine the output voltage from each cell to create increased voltage.
Four 1.2 volt NiCad battery cells wired in a series produce 4.8 volts.
A problem, though, is that not all battery cells go dead at the same time and this is particularly the case with NiCad cells.
This means that while the battery for your drill keeps running out of charge quickly, it may only be one or two cells that are causing the problem.
You don’t have to buy a new battery for your drill just because the old one won’t hold a charge anymore.
