Thread: Deep Cycle Batteries - AGM or Gel??

Hi,
Battery University is a good site for info.

cheers

Hi Gavin, my understanding is that deep cycle batteries are not good at supplying large amounts of current in a short time, such as needed when winching. This sort of demand would probably damage them. They are ideal for running lower demand items like fridges and lights and will be able to do so for quite a while before needing recharging. Cheers, 130man.

Hi Gavin and 130man is on the money.

You will either need something like a spiral wound AGM, such as an Optima YELLOW TOP, or a dual purpose battery, a marine type battery.

Most standard AGMs are not suited to winching and personally, I would not trust a gel as far as I could kick one.

A dual purpose marine battery would be the cheapest option.

BTW how are you planning on connecting this battery up for winching?

I've got a SSB 130Ah AGM as my aux battery. Only had it for about 6 months so can't comment on its longevity, but very happy with it so far.
Have it set up with a SC80 controller and a manual switch that parallels it with the start battery for use as an emergency jump start or for winching. Mainly it just runs the fridge and a couple of other sockets for a small inverter and charging phones etc.

Its a pretty big bugger, but I've managed to squeeze it and a N70 Calcium in the battery box of my County.

my 2nd battery for running the fridge [constantly on full of drinks] is a century "marine" battery, my reason for choice was 24 month warranty over 6 month warranty on deep cycle, been going great for the past 12 months. purchased at supercrap purely so i can take it back to any store if dramas arise.

I went with a pair of Yellow Tops ... D31 for starting (900cca/75AHr) shared with a D34 (750cca/55AHr) using a Traxide USI-160.

So far it's been excellent! Both batteries are under the bonnet. Gets me around 2.5-3 days (47L ARB fridge & LED lighting)

Thanks Steve. Now this would appear to be a competitor for the yellow tops. Comments anyone?
