Default Re: Optima battery will only chug to 50%

Battery charger is a scheaur(spelling) that has a percentage meter also has settings for agm settings,
I also have optimum batteries in my roadster and model A ,at least 10 years on both and very little charging with tenders,really good service...
Battery in question reads 6. volts, but won’t last very long on running engine on engine stand,voltage to coil drops to 1 volt in a short time,,,,changed 3 carb,and coil befor I figured out problem of low volts,,,
I’ll try to discharge completely and try and bring it back up slowly,,
