Thread: Charging a battery

I think the lower amp chargers "will" charge the battery "overnight" .... but, it may well take "all night". I put mine on a 10 amp charger and it's ready to go in a few hours.

Might also depend on what size battery you have ... and what type charger. I'm charging a Series 29 Deep Cycle battery with a Minn-Kota 2bank onboard charger @ 10a per bank. (the other bank I use to charge my other series 29 DC battery or my series 24 starting battery)

Don't know about a 3 amp but a 5 amp per lead has always served me well. Never a problem.

Depends on the battery size/reserve capacity, how much you typically discharge it, and how much time you have to recharge before your next use.

If you typically run a 100 amp-hour battery down to 25% then it would take 25 hours to recharge it with a 3 amp charger. For people who fish long hours multiple days in a row, they don't have 25 hours between hitting the water....for that same scenario a 10 amp charger would finish charging in 7.5 hours.

I use a 5amp charger, charges my 3 battery's overnight. It's a 3 bank on board charger.

5 amps minimum IMO.

I have used some slower trickle chargers and they took almost a whole day to charge. I have a 2 bank 5 amp charger now, and it's usually done in a few hours.

I use a Minn kota "Precision" 212 . I had it before going to a 24 vt. trolling motor . I still use it to charge trolling motor batteries. I have never seen it not ready to go in 6 hrs . This is 6 amp, per bank .
