Hi, I had just bought a used battery charger and I have no clue what amp setting to put it on to charge my 12 volt lawnmower battery. The charger has 50,10, and 2 amp settings on it. What amp is best for lawn mower battery? Thanks
 
10 amp for lead acid battery; although, 2 amp is slow charge way. 50 amp is considered jump start method for automobiles.
 
No higher than 10A for 1hour. Place it on 2A if you have time to let it set and slow charge. 50A is for a quick start, but you risk blowing the main fuse.

If you need a battery, don't put it off because the mower will damage the charging circuit. For battery longevity, get a solar panel battery maintenance charger and leave it on the battery (while outside in the sun) at all times when not using the mower. It will triple your battery life. I have been using them for years and it works.

2 amp trickle charge is the best. Hook it up and come back next day. It will float once fully charged and not overcharge the battery. Remember most of the newer chargers less than 25 years old will not recognize a battery and start charging unless battery is at 12.0 volts or higher.

So will a discharged battery still read 12.0 volts on the new chargers?
 
So basically all

So basically there are 2 ways to charge a lawn mower battery. I can either fast charge battery at 10 amps or slow charge battery at 2 amps? Which do you prefer?
