WHICH DEEP CYCLE BATTERY TO BUY

Big Gorilla · Guru

I use Century C105 6 volt Deep Cycle batteries, 2 connected in Parallel to give 12 volts. You can buy a 12 volt version. They are not cheap. I can't recall cost of 6 volt batteries, but the 12 volt is around $600.00. My 6 volt batteries are 225 amp/hour each.

I am currently using a century 120Ah AGM that cost me around $350. It is installed in the rear of my 4wd and is charged by a redarc dc-dc charger and 120 watts of solar panels on the roof rack. This setup runs my 80 litre fridge freezer.

BG I am sure you meant you hooked those 6v batteries in series to get 12v!! must have been a typo huh.

Big Gorilla, you mean you have the batteries connected in series to get 12 volts from two 6 volt batteries. "Not in parallel."

Your batteries are 225 amp/ hrs, that gives you 225 amp/hrs. You double the volts but not the amps.

Batteries that are connected in parallel, voltage remains the same and the amps are doubled.

I stand corrected.. The guy at battery world told me to keep the 100 ah as the battery lasts longer...

We've had 4 Absorbed Power 100AH AGM batteries in van and 3 are 8 years old. we look after them and I've phoned the QLD distributor 3 times for supply info and nothing heard back.

I'm going to change to Fusion batteries 4 X 100ah and have a competitive price,, see this link

After many enquiries I've found some batteries are overly cheap and hence quality is questionable or excessively priced due to profit margins.

Best price I've had is in the link above as this is a significant discount.

Also here's a good site to see what's availble

His logic was the higher the AH the more the variance and is harder on battery ...

Reducing battery life ..

I didn't really agree with his logic!!

The batteries ( name brand) I bought where over $550 each

got the two for $920 .. Working good and hold charge...

The old batteries are over 10 years old...

Hi All.

I use 1 only Lion DCM 31 120 amp battery with some success. Cost of $300

120 watt solar panel.

In our caravan we run all Led lights, sometimes a 12 volt fan and a water pump. No television.

We have been very happy with this amount of power, most times we stay out for 3 nights and then get low on water, we do enjoy this freedom of moving around. At our usage rate in not so average weather I would think I could go up towards 2 weeks of freedom camping.

We do have a second battery set up in the tow vehicle a smaller battery that I could connect to the van when needed.

Good quality battery at a competitive price.

Hope this helps. Ralph.
