Charging Battery
Am I able to charge my battery over night with a 10AMP AGM battery charger? I bought a new battery back in May, and haven't been using the charger when doing MHD updates (about 7 times). Would i be hurting or helping the battery if I attached my charger to it over night?

Is it a smart charger?
If it isn't, there's the concern of overcharging and damaging the battery, I think.

Agreed w/ the point of checking if it's a smart charger, some will continue to charge even after the battery's good and then proceed to try to over charge it which may have consequences.

If you haven't driven the car since you used the battery for awhile with the car off, then it might make sense to charge it. But if you have driven 50 miles or so, I doubt you need to. If it is cranking OK, I wouldn't bother.
My 2009 is on the original battery and has never been on a charger. It sits for up to a couple weeks. Normally sits for several days each week. Always starts easily.
