Re: Custom Chargers for backup battery
We built a couple (one for a spare) and measured ~98ma charge current with a fully charged backup battery (~7.4v). Disconnecting the 12v and the RC we measured a ~5-6ma discharge current back through the charger circuit. We haven't pulled the 43ohm resistor, but the next one we build we leave out this resistor to measure how much charge is coming through the regulator and how much is unregulated through the 43ohm resistor.
