Are auto batteries maintenance free?

No you sometimes need to charge your battery or get a boost if you battery runs low. Leaving your lights on for instance will totally drain the battery.


Battery draining on lawnmower?

Answer Most of the time the battery is loosing charge on a mower it is bc the battery is going bad. The cells inside are wearing out and not holding a charge. Replace the battery and usually the problem stops. If it is a acid fillable battery then make sure the battery has the proper amount od distilled water and acid in it. Also if it is a serviceable battery then I would replace it with a maintenance free battery anyway. A lot less to mess with. Good luck.


How do you charge a maintenance free battery on 2001 limited pt cruiser?

For a maintenance free battery, you need an automatic charger, I recommend one that has a switch for gel batteries as they tend to be more gentle in 'gel' mode, also use the slowest trickle charge option. Also look for the feature 'maintenance mode' or float charging, as these really help the battery. You just plug in overnight, and can turn off at your leisure with these types, and usually have a light so you know for sure they are ready. The idea is to reduce the internal gassing of the battery, which in a maintenance free battery, you cant top up the water, so you need to be much more careful.
