How to reduce current?
There are two ways to provide a current-limited supply to charge a battery. a) The current limiter way. Use an active current limiter. ... As the battery voltage rises, the drop across the resistor will fall. This will reduce the current, unless you are monitoring it every few minutes and adjusting the supply up to compensate. Quick to do …
BU-403: Charging Lead Acid
My standby charge for a 20Ah sealed lead-acid battery starts when battery voltage reaches 12.8V, after which I charge with constant voltage at 13.65V until charge current reduces to 50 mA.
