12 V Nicad Battery charger1 300x170 12V Nicad Battery charger 200mA/H

This 12V Nicad Battery charger 200mA/H circuit charges the electric battery at 75 mA until the battery is charged, then it cuts down the current to a trickle rate. It’ll fully recharge a dead nicad battery in 4 hours and the battery can be left in the  Nicad Battery charger for a long time.

Setting the shut-off point, connect a 270 ohm, 2-W resistor across the charge terminals and adjust the pot for 15.5 V across the resistor.
