Deep Cycle Batteries

Hi All

I am looking at purchasing a new 100ah (approx) Deep Cycle Battery and would appreciate some feedback and advice on the best type and brand.

I use this battery as a backup and to run my engel when not in the vehicle.

Hi Hawk,

I can recommend a forum member that I got a 100amhr agm from at a very reasonable price and great customer service. He answered all my stupid questions.

It ran my 60lt Engel for over a week with a solar panel attached and worked perfectly.

A Fullriver 105AH or 120AH AGM battery sells for around $300.00, see the Ebay links below. Plse ensure you have an appropriate lead acid smart charger etc for charging when not connected to the vehicle. These are hybrid batterys which are also deep cycle. You can buy the heavy duty deeper cycle from the same makers but for general purpose use these are fine.

Don't believe there is a "best type" or "brand".

I decided on a Remco branded 100Ah AGM true Deep Cycle battery, available Australia wide from Whitworths Marine outlets for $339.

If after a wet cell deep cycle it's hard to go past Trojan batteries for heavy contruction & a long life.

Maybe you had better luck than I but my Trojans seem did not to like shaking. The two installed on my sailboat gave far less than expected life, despite being charged daily via regulated solar panels. The water level also required constant checking.
I now use maintenance free Delco 31's. The best service life I got was from AC Delco Voyager batteries, still working after 6 years service. Unfortunately these are no longer available I believe.

Trojans have been the benchmark in deep cycle storage & are highly regaurded by solar companies & RV installers. I've certainly had an excellent run with mine. Yes they do require occational checking of the electrolite level as if the plates are exposed for any length of time would lead to premature failure.
With the angles a sailboat gets on it wouldn't surprise me yours had a short life. I would have thought a sealed AGM or Gel battery would have been a better choice for your particular application.
