This is for a Makita 6932FD impact driver. It runs off a 14.4V NiMH battery of 2.6Ah. I ordered sub-C cells (with solder tabs, don't worry :P) that are 4.2Ah.

I was reading about DIY NiMH chargers just out of curiosity. The author used a PIC to monitor charge termination based on 3 conditions:

  1. dV/dt
  2. Temperature
  3. Time

So that got me thinking, I believe the highest capacity of OEM battery was ~3Ah. So will the charger be able to fully charge it? Or will it take too long, and get cut off? In which case, I'd have to

  • Use it as is
  • Unplug then plug in the charger again to "reset" the count
  • Get a different charger, probably one for RC batteries as this is the target audience of the cells I bought

Rebuilding Makita NiMH Battery with Cells of Bigger Capacity. Will it Charge Properly on the Old Charger?
