Charging batterys

[steplift20]

I have two batterys
Should I charge them one at a time or hook them up together so when I charge them I just have to hook up one?
Does it make a differance?

depends on the battery. Are they both starting batteries? Deep cycle? You're never supposed to combine different batteries. Are they the same age? Both good? I charge two batteries at once all the time thru the battery switch, mainly because I'm in a hurry and only have one good charger right now. Are they real low? Its best to charge them separately. Load test each one to determine the condition, check each cell with a volt meter to see if you have a problem. Are they just a little low? charge them together under low amperage.

Both everstart starting batterys. One is newer than the other one.
I think I will charge them sepperatly just to be sure, I will charge them with 2amp 12 volts. It keeps them about 13.2 when I disconnect them they drop to. One about 12.6. The other 12.5

hard to tell. Like spare noted Test voltage under a load,see what it drops to.

I have dual batteries and charge them both at the same time,no issues
