Deep Cell charge... 2 amp or 15 amp?

4 posts in this topic

My charger has two settings... without going outside to look.. I think they are 2 amp charge and 15 amp charge...

What is the difference (besides 2 amp taking longer!)... is one better than the other for getting the best charge and keeping the battery healthy?

Use the 15 amp on you deep cycle battery, it'll cycle down to nothing once the battery is charged. Some guys will use the 2 amp for maintaining the battery during long term storage, personally once I charge a battery I take it off the charger and will do a maintenance charge every few months.

Small batteries like motorcycle batteries use the 2amp setting.

Be careful about using this type of charger for ‘maintaining’ a battery. If it does not automatically lower it’s voltage to 13.2 – 13.6 volts then you run the risk of ruining the battery if it is left on the battery for long periods. ST is correct in that you should disconnect the charger during storage. The beauty of the ‘on board’ 3 stage chargers is that you can leave them connected to the battery for as long as you want without hurting the battery.

      I think it might be time for calling season. I've got the itch. Been working the hand calls the last few days. The neighborhood dogs and cats fall for em almost every time. New batteries in the foxpro and the critter just in case. Got plenty of #3 buckshot for the 20ga and the rifle is ready to bark(as soon as muzzle deer is closed).   please stop and share your seasons ups and downs here. Otherwise I will try not to bore you all too bad with my pour calling and shooting.    Good of luck and happy calling.

      Yep, glad they took the snow out of the forecast for next week except for some flurries on Sunday but that shouldn't hurt anything. They lowered the temps a little more also. If the forecast holds and the wind stays down I think the lake could lock up by the 9th or 10th. Walked down to the shore this morning expecting to see some ice along the shore but nope. Looked like there was a little skim out in the bulrushes but that was it.

      then I will need to buy the bigger dewalt batteries. they look spendy.  I have 7 ryobi batteries now. 2 are the 4 amp.    600 pounds should be plenty  from what all are saying. I can take the 2 , 4 amps back and grab the dewalt. hmmmmmm, decisions desicions. lol
