Any ideas on which is the best deep 12v deep cycle battery to buy? How often do you need to charge them up when not in use.

SEARCH ON GOOGLE FOR--FULL RIVER BATTERIES---AGM-DC.
ASK YOUR LOCAL ARB STORE WERE DO THEY BUY THERE BATTERIES FROM.

It will depend on the application as to which is best. ARB would be unlikely to have any idea as they would only sell 1 or 2 different brands & would never suggest anything else. 12 volt shops & solar supplies would be better equipped to recomend a size & brand to suit your requirements. Self discharge is different between makes so topping up the charge will vary. Trojan are often seen as one of the market leaders in wet cell deep cycles & I can recomend them as being a quality product.

Bloody expemsive for a wet cell though (the trojans that is). Never dealt with them personally so can't comment on their quality, but they were twice the price from "the 12 volt shop" than the equiv. of mine.

Firstly - I would be going direct to outlets that deal in batteries, they will know about what they sell. Yes some will say they will push a particular brand toward your pocket, but, you should do a better deal here.

Secondly - Deep Cycle... I am asuming it is for a second battery? If so why not consider a Farm / Tractor battery, they have bigger plates and can be drained and charged over & over, plus they would come at a cheaper price.

I have had a Farm / Tractor second battery( Century) for about four years now and it is still going good.

Batteries - like tyres as nfar as the list of what to buy. Checkout the dealers.

Good Luck

G'day
I know very little on the subject but heres my recent experience. About to head off and short on deep cycle battery for the caravan, asked a mate who is an electrician by trade and more to the point a mad keen 4wdriver/caravanner/camper. He reckons the marine batteries a pretty good and the deep cycle ones arent that great anyway. As I already have 2 marine batteries sitting in my boat, I thought dah, I'll use one o dem. LOL
I'm sure theres a lot more to it depending on your application though. This one will only be used for 12v lighting if at all, just a back up really.
cheers

The problem with many batteries is often they can't be fully charged by the vehicle alternator due to various inefficiencies, it is not a fault of the battery but the configuration and implementation of the dual battery system.

When you compare a fully charged Deep Cycle battery with a starter battery and use them to power a fridge there is no comparison, as the DC will last far longer than a starter battery, read any realistic website that is knowledgeable in the specifications of batteries.

Then if you are still not convinced look at the battery charging system and battery bank inside any large motor home, won’t see to many with a row of starter batteries, then ask yerself …why not, what do they know that you don’t ?

If it an aux battery then go a glass mat battery they are really good for the long slow drain EG. running the engel/weaco etc and lights. They are also easy to charge and love solar panels.
Look at

I used to have a handle on life, but it broke.

I've now got two century deep cycles.
Best price I could find was batteryworld. 30 bucks less than elsewhere.

If i'ts real cheap avoid it.

As far as I know, deep cycle batteries require recharging inside of three months.
But more importantly run them almost flat every so while... Some would say don't run them fully flat, others would say it doesn't matter.

Try not to use them for any high current drain applications unless absolutely neccessary. (Such as starter motor or winch).

About 12 mnths ago fitted Cent 50amp/h as aux in Jackaroo TD. Headed off syd-perth-drwn-c/peedy-syd for three months. DC batt was running 80L waeco. Lasted for about 30 -40 hrs, depending on outside temp, before fridge cut out. Took about fifty k's hwy driving to recharge. Fitted Matson voltage sensing relay from Batt World who also supplied batt and free advice on fitting, also helped out with batt system in camper trailer. Everything worked as promised and lasted the 20 000 k trip.
Orbital are very nice but pricey. D/C batts do require some tlc as outllined by Dan 1, they will last much longer.
