Can I replace the cells in my drill battery?

Can I replace the cells in my drill battery?

Power Tool Batteries: Replace the Cells in the Battery Pack You’ll need new cells, a soldering iron and rosin-core solder, a glue gun, and some wire and tape. The whole process takes about an hour. Most power tool battery packs use 1.7-in. Then remove the cluster of batteries and measure one of the cells.

Can cordless tool batteries be rebuilt?

Lithium Batteries cannot be rebuilt. Many cordless power tools use nickel-cadmium (NiCd) or nickel metal hydride (NiMh) battery pack rechargeable batteries, after a few years, these batteries no longer hold a charge. The NiMh batteries we build will last twice as long as the NiCd batteries. …

How does a Li ion battery pack work?

Like most Li-Ion battery packs, the cells are connected via spot welded metal strips. To remove the cells from this pack, I unsoldered the sensing wires, and then used a wire cutter to cut the strips as they wouldn’t be reused.

Can a drill battery be replaced with a new battery?

This means you don’t need to purchase a new drill, to take advantage of the newer, much-improved lithium battery technology. You can simply upgrade your old drill’s battery by replacing the battery cells in it. I have now found and added a third video. This video explains how to revive Li-Ion batteries.

What’s the voltage of the drill battery pack?

This was a cell voltage of between 4.1-4.2 depending on the charger. The variation was likely due to tolerance on the different charge chips. The on board battery level meter in the pack showed full right away. Testing out in the drill, it works great, and charges correctly on the drill’s original battery charger.

How many Li ion batteries can you hold?

They are pretty much everywhere you find Li-Ion, unless there is a tight form factor requirement; usually thin devices. Added to this, 18V is 5 times the nominal 3.6V 18650 battery voltage, and the form of the pack could reasonable hold 5 of them, plus some electronics. After finding the appropriate security torx bit, this was proven correct.
