I would try another brand, could look at (yellow top optima) they cost more but I have been told they are not to bad. The yellow top are deep cycle and to can duel used as a starter

So what the hell are all those D cells doing lined up under my bonnet??? LOL!! (not a hijack!! lol)

Let us know how you go mate with the revs up for what charge you are getting - for what it's worth after all the above, I'm going heat.

D Cells... ROFL, you dunno how close to home that comment is... Seeing as I get any amount of 7 AH 12 Volt Gel Cells I used to use 10 or 12 (sometimes more) of them hooked in parallel in my Camper at one stage. Jeez it was a PIA finding dud ones tho

As for temp I am in agreeance, the source of the "excess" temp is perplexing. Looking forward almost as much as Nowoolies to finding out what the issue is.

How did you go with this Paul?

I'm having similar issues with my 4.8 Petrol aux battery, warped battery cases etc... I'm guessing mine is temperature related due to the amount of heat the 4.8 generates under the bonnet and the location of the battery being near the exhaust manifold.

Cheers,

mine's not showing any signs of blowing yet, and it gets so bloody hot you can hardly put your hand on it (which can't be good for the battery at all)

i can relate to dead batteries, mine was killing batteries every 12 months or so. Charging system was putting out anywhere from 13-15v. The cause of the over charging was someone had chopped the sense wire leading to the alternator which tricks the alternator into charging at a higher rate. They did this to compensate for the size of the wire between the alternator and the battery being under size from new. I ran another 2 x 6mm wire from the alternator charge bolt to the battery and rejoined the cut sense wire, now it charges at 13.8v and no more dead batteries. I have a mate who used to work for Nissan and he said it was something that some mechanics did to solve low charge issues, it wasnt endorsed by Nissan but was still done.

If your battery if getting wet then the system is over charging as this is what mine did till i upgraded the charge wire and rejoined the sense wire. As for heat to a battery mine gets excessively hot under the bonnet and you cant touch the battery after 30 mins of running and the current battery is over 3 years old, the deep cycle i removed from the passenger side was over 4 years and still going strong in my camper, aprox 5 1/2 years old now. Not saying heat is any good for the battery but they shouldn't be doing what they are doing.
