Quest for the shittiest battery charger continues. (schematic)



The quest for cheap and particularly dubious battery chargers continues with this fairly neat three AA cell charger for NiMh or NiCd cells. But only three at once. This is another of those products that is worth getting for the case alone.
This charger has no electrical overhead for a reverse discharge diode, so if left plugged into an unplugged charger it could self-discharge or try to run other devices in reverse.

12V Lead Acid Battery Charger(Homemade)



I took a MOT and carefully stripped out the 2000V Secondary and replaced it with a low voltage high current winding of 18-20T or 12ga wire. New fully rectified DC output is 15.8VDC. An electrolytic capacitor of 1500uf was also added for smoothing purposes(Not much smoothing is required for charging lead acid batteries). Also includes a voltage monitoring circuit which allows you to know when the voltage of the battery being charged has reached completion. A green LED will be brightly illuminated to let you know to unplug the charger.

Schematic Here:

The circuit in the schematic above will connect to this automatic charging cut-off circuit, then to the battery to be charged:
