[battery for 54lb thrust 12v water snake]

Well there you go. Myth busted!

Sulfate crystals dont so much "build up from the base of the battery", they tend to "stick" to the plates and enter the pores in the lead then as they crystallise they break off small particles as they expand. The particles then settle on the bottom of the battery.

Maybe i'm guilty of being sceptical but I will still not be sitting batteries on concrete.....

Cheers for the info.

Yeah, I thought that post was a bit odd and was thinking cold concrete sucking the heat out of the battery which I reckon could lead to overcharging?

I am running twin Ultimate batteries on my 80lb minn kota and it lasts all day 24volts

I use a C-TEK charger and while expensive it works a treat and I leave it on most of the time.

Thanks Swordfisherman,

Did the "research" and ended up buying the Ultimate UL-100 for less than $400 , weighs nearly 30kgs!

I'll give her a run as soon as the Sydney weather clears up!

Got her sitting across a Power Tech Plus MB-3620 charger that utilises a four stage charge system -interestingly she was fully charged ex the store, so has a good shelf life!

Hi There,

Batteries a strange "organic" creatures, treat them bad and they turnup their toes and die.

Discharge and Recharge them incorrectly and they'll die young!

Lots of vibration in a boat, so go for a Absorbed Glass Matt (AGM)

Sounds like you need 2 batteries, 1 (starting >CCA) to start your motor and 1 (deep cycle >Ah) to run your electrics as there's no battery that does both very well or for long!

Get a good 3-stage charger to maintain your batteries and they'll reward you for it.

If they stay in your boat probably better off with "maintenance-free" sealed battery - got to be a Absorbed Glass Matt (AGM) if you want it to go the distance!

You get what you pay for, more Ah greater cost - check the weight as this will give you an indication of storage capacity generally the heavier the longer the run-time.

I run a 100Ah (AGM type) on mine...its heavy but does the job well! .....

Hi Guys,

What sort of run-time do you get with a 100Ah?

I have a 36lb Minn Kota Riptide, not sure what current it pulls flat out - probaby 30Amps or so?

Is anyone using the (red) Ultimate range of deep cycle AGM SLA batteries?

I like the idea of being sealed as no acid spills or terminal corrosion!

Cheers
