What agm battery are you running

Post by the big one » Sun Nov 24, 2019 6:41 am

Hey guys looking at upgrading my optima battery as it doesn't have enough AH to run my Minn kota for a long period when the wind is up.

Im tossing between the century agm 105ah
Or the power crank agm 110ah .

Has anyone ran them and do they last. Or what type of battery are you running and how long have you had it for.
Thanks guys.

Odyssey batteries have a big rep in the USA bass market. There is an Aussie distributor but I don't know who sells them up north.

Whatever you decide to get make sure that its a REAL deep cycle battery.

Mostly the ones on offer to unsuspecting users are simply cranking or marine (hybrid type) batteries.

If the battery advertising blurb even hints at CCA cranking amps, dual purpose or marine avoid it as it wont be a real deep cycle.

Been many a keen boatie sucked in by a distributer.

I've had a 120ah Chinese deep cycle for 3 years and charge it on a smart charger NOT a standard charger.

Unless you end up with a lithium ion battery (expensive) but they can be discharged to max levels (70% or more unlike a standard lead acid AGM type of 50%). Quicker to charge too.

Remember that you are NOT looking for power, high cranking amps etc for what you want to use the battery for.

Not all ebay batteries are dodgy.

Beware ANY dodgy batteries and there are heaps out there from some supposedly reputable manufacturers.

This is the AGM that I use (only a 120AH version). Its a true deep cycle.

Approx $365 delivered to Darwin.
