i just got a 12v 20ah battery for my sonar, my question is how do i charge it. the 7ah ones i had from cabelas came with trickle charges but that doesnt seem ideal with a 20ah battery. have two bigger chargers that im curious if i can use. one is a vector that can charge wet, gel, agm at 2a, 10a,30a. and a schumacher that does standard, gel, agm at 2a, 6a,10a. can i do it with these chargers and if so what settings for each?

If that's a motorcycle size battery, which it looks like, then charge at the 2 amp rate. Slow and steady on that size battery. That's how I charge my quad batteries.

If you had to put the acid into it and then put the sealing cap on, then its wet. If you bought it and it just says charge it, then it should be agm.
