I usually charge NiCd/NiMH batteries just by connecting them to laboratory power supply with current limiting (set somewhere between 0.1 and 0.5A) and watching voltage. After it goes over 1.5V/cell, it is charged. Most dumb chargers, including Tesco drill (at least the 12V we have in brmlab), do exactly the same thing.

Hi everyone.

I have a battery and base station for an 18VDC cordless drill from Tesco. The old transformer/charger died like most of the functional toxic waste from China. I want to replace it, but I don't recall the specifications. I believe the base station is completely dumb with no electronics, only like a connector and some LEDs.

Knowing this, does anybody know what specifications of the power supply should be to properly charge the battery? I know it may need conditioning, but I can do that myself.
