charging agm battery

I have one in the Camper, and it sat for 6 months between uses. Still had 13.6 volts, so the best way to maintain it when not in the car is probably to do nothing.

They have a long shelf life, but if you want you can use one of the low output 3 stage chargers and leave that on all the time.

Not necessary in my view.

Hey Dublediff,

The main thing that kills batteries is scale on the plates - the best thing to do each month is boil the battery. Scale forms through general use but happens when you cycle the battery (run it low or empty). Mega pulse and Rotronics Dual Battery Kits do similar things in they revive and keep the battery free from scale.

AGMs are very tolerant of lack of maintenance BUT are not immune to it.

Ensure that the battery is fully charged before you put it into store.

Ideally, maintain a permanent "float" charge on the battery of approx. 13V8 - check data sheet for exact number.

Less ideally (but still pretty good) every month or two, at most, apply your normal battery charger to it and ensure it is fully charged. (This is what I do).

Charge it up, then leave it !! Check its voltage every month and if it gets down to 12. 5 ( anywhere close will do ) give it a top up !! Simple !!

I don't like the idea of having a charger ( no matter how good it is ) trickling the batts that are deep inside the CT for days or weeks at a time !! No need to so I don't..
Now lead acid would be a diff story !!!

Thanks for the info, after an expensive purchase I started to panic that I would kill it like a gell cell I killed once, Cheers Eric.
