Hi Guys and Gals
I have a deep cycle battery on my trailer and daul batteries on the cruizer and it charges trailer battery while on the run. My question is if im at a powered site after 2days the trailer battery will run my FF90 fridge/freeze but my 12volt fluros wont start i have a 808 charger and it seems to be working but the 3 fluros only run for about 5mins and they go to start but stay very dim. If i couple to aux battery on cruizer and deep cycle as it set up this way they work fine. The charger was recomended by the waeco frige shop. The fluros r versa-lite 12volt type. Any help would b gr8
thanxs

Munny,

Forgive me, but what is an 808 charger?
Many post replies and follow-ups on the forum about this problem.
Deep Cycle batteries have copped a fair amount of citicism.
Summary:-
They are designed to be charged and discharged regularly BUT they don't like to be discharged below about 40%. It shortens their life dramatically.
They take longer to charge than a cranking battery.
A standard vehicle alternator/voltage regulator will not lift the charge, at best above 80% (some say 60 to 70%)
They can be charged to 100% using a "smart" battery charge, hence my question about an 808 charger.
They can be charged to 100% using solar panels and smart solar controller.
The above depends on the current health of the battery due to incorrect use/maitenance and the level of sulpation of the plates.
There are some products on the market that are said will fully charge the remote battery (trailer/carvan mounted) from the vehicle's electrical system e.g. ARRID twin charger. I am still looking at this device and cannot offer a personal opinion re the manufacturer's claims. Others may be able to comment

Hi Roscoe, I fully concur with your comments & highly recommend William Dardens site on understanding the workings of lead acid batteries & how to correctly maintain them so that you can get the maximum life out of them. I have been using his practises for a lot of years & from experience it works. Cheers.

I don't think your charger is putting in enough current for both the fridge & fluros, unplug the fridge & see if the fluros work, if they do that's probably whats wrong
