you charge a atv battery at 2 amps or lower
As long as the ATV is wired 12 volt, not 6.
I am assuming you mean with the auto engine running. Yes, that is possible but you are putting a strain on the alternator of the car. An alternator is not designed to charge a dead battery. It is designed to keep a charged battery fully charged. as long as the ATV battery is the same voltage as the car battery, usually 12 volts, you can charge it, or jump start the atv and let it charge the battery itself.
Not at all. A 35 amp charger is far too large to charge a lawn mower battery. Use a 10 amp automatic charger.
You can safely charge it with a 15 amp charger. You can also charge it with a 1 amp charger it will just take longer. Do not overcharge the battery.
There is no only one way to charge it and that is with a battery charger. A 15 amp battery charger will charge it about as fast as it needs to be charged.
You can safely charge it with up to a 10 amp battery charger.
A .6 amp charger is a trickle charger. It would take days to charge a dead 12 volt battery with this charger. You need a 10 amp charger which will charge it in a couple of hours.
Yes, it can be used to charge that battery. The chargers rating, 2 amps, is the maximum that can be drawn from it.
It charge faster
no, if you charge 9 volt battery with 12 volt battery you will destroy 9 volt battery
Yes, you can.
Yes, the only difference is one will charge twice as fast as the other! -Dale
