Charging deep cycle batteries. 10 or 2 amp?

4 posts in this topic

I have a battery charger with a switch for deep cycle batteries. It is an automatic type charger so it will click itself off when done. My question is what is the best amp rate to charge a deep cycle at, 10 or 2 amp?

I usually have the time to let the 2 amp do a full cycle so time is not really important.

Gonna be different views on this question. My take is as soon as a battery is below full charge it starts to degrade. As soon as you can you should charge it as fast as you can and i reommend the 10 amp charge then maintain with a 2 amp charge.

Your charger is made specifically for the deep cycle battery. Use the 10 amp setting. Even though it says 10 amp it'll taper down to nothing then shut off. If you want the battery to last as long as it should. Keep the levels up. Charge it after every use.

Store it in a cool place.

I recently did some reading at Exide's HSOforum on this subject and their latest recommendation is a slow 2A charge. The reason being that when the battery is first connected and has a low charge it will draw higher current. With the charger set at the 10A setting, it will deliver the 10A if the battery asks for it. Unfortunately, this can cause excessive heat buildup and evaporation. Whether you use the lower amp setting or not it is important to keep an eye on the electrolyte level of your batteries but more so if you use the 10A setting.

    • So we support intelligence depts now?
    • You mean fake Bruce Springsteen.  The real one is a librul and the fake one didn't want to urinate on the bed of the real one.   I'm sure Trump wanted them to play "Born in the USA" like all the other politicians that have no clue what that song is about but like the chorus.  
    • I'm trying to wrap my head around this one. Obama truly is a bigger POS than I thought. Good, God this is bizarro world. By commuting the sentence of this freak show, it's like burning down all the intelligence depts. Why do we have laws? 
    • So Obama is mad at the Russians for hacking and Wikileaks for publishing the hacks yet he just Pardoned Chelsea Bradley Manning who stole secrets and gave them to Wikileaks   This is a real WTF moment.
    • You failed to post the very next part of that very article:     You never patted Obama on the back for any of that oddly enough.    http://www.reuters.com/article/cbusiness-us-gm-tech-center-renovation-idCAKBN0NZ19920150514   So either congratulate both or congratulate neither.
    • Because you are banking on not having to pay it back in your lifetime and are perfectly fine with passing that debt down to future generations which allows you to live a better lifestyle at their expense.  Some of us don't think it'e ethical to pass debt onto generations who will have no say in the process.
    • Buddies from Michigan, MN, ND and WY got here Sunday, started hunting yesterday. Yesterday coulda gone better and coulda gone worse. We had 2 spots in a marsh that we were debating on setting up. Chose spot B. Had we chose spot A, we woulda been absolutely covered up in birds. There was about 1500 pins, teal and a few wigeon sitting there when we came by. at least we shot a couple nice bwt. Total take was 17. One drake bwt was already in the freezer when the pic was taken.    Day 2 was a diver hunt. Mainly had redheads come in, with one nice flock of scaup that we dropped 7 drakes out of. Had 3 flocks of buffies buzz the edge of the longlines but not commit to
