This is my chassis battery, an agm I got used and have little experience with. Trickle charger failed in storage, it is dead as a doornail. Not covenient to babysit it for long hours on meanwell or...

As the sulfate ions move back into the electrolyte solution the resistance drops and current flows faster and faster. Once you get above 11 or 12 volts the battery should start to act more normal.
Okay Max, will do. Starting was around 1.8 volts or something.
6.8 volts? Keep charging. 5 to 10 amps is plenty. Just let it charge several hours until you get the voltage up to 14.5 then keep a steady voltage until amps drop below 1.
Watch the battery temperature. If battery is shorted it will get hot.
