Just make sure the charger can reliably charge the Ah rating of your battery. Automotive chargers are 12V chargers, but the battery will come off the charger around 13.5V

i own a shop and if you want a really good one i suggest you go to sears and get real good one,they have the ones that offer the boost feature also that allows you to start a car with a dead battery,and there not to expensive either,i think i payed around 100 bucks for this one i have and i have used it for over ten years without any problems,it also has the slow charge feature on it which i like because fast charging a good battery will ruin the cells in it,advance auto parts also has one for about the same price that works as well and i think its a few bucks cheaper also,if i was going to use one a lot,id get a good craftsman,from sears,good luck with it,i hope this helps.

It is a matter of speed. The charger should have 6Volt and 12Volt on it.
Amperage is the rate of flow. I have just a 10A but I can wait overnight in the majority of cases on a dead battery.
2A charger doesn’t do anything really.
6A is very slow
Deep cycle is for RV and electric boat motor batteries.
A quick charger sends a high amperage thru the battery so that you can start the car almost immediately (however it is hard on the battery as that jolt tends to warp battery plates and warped plates can touch each other, killing that cell)
I have used mine so many times over jumper cables, it has paid for itself 20 times over.
