Battery overheating

wrap your new battery in aluminium foil....

You should have paid a lot less for your new deep cycle, then it won't hurt so much if you lose the new one as well :P

Best, Peter

G`day ajd,
There is available insulation material that consists of a sandwich of Fibre Glass about 15mm thick between two sheets of light gauge steel.
My 60 series has a panel of this underneath between the muffler and the floor, I reckon it would be easy to make a shield for the battery and maybe even direct some air flow between the shield and the battery.

Scrubby.

yeah you can get an exhaust wrap may have to be custom made, check exhaust suppliers, or mining equipment suppliers as there are alot of turbo wraps fitted to underground gear and other machines where extreme heat can be a problem in surounding areas

Wrapping your battery in foil or arranging any other form of insulation will not keep your battery from getting hot unless there is a cooling airflow over the battery inside the insulation. Otherwise all the insulation will do is provide a very short time delay in heating your battery.

If your deep-cycle battery is AGM or Gel they do not like heat so the very best solution is to move it out of the engine bay to a cooler location.

ajd,
Not sure what these people are sipping tonight..... I think the aluminium foil was a poor joke - not sure about the metal shield, but shielding a battery with anything metallic is a surefire way to create a shortcircuit, melt a battery or create a fire under the bonnet.

You can buy a proper battery thermal cover : Link Here


But your choice of an AGM is not the best under the bonnet - they don't like the heat - If it were me, having spent the money, I'd be moving the AGM into the back. A good wet cell battery is more likely to last in a warm environment - something like a Exide extreme or Century overlander is what I've used for second batteries under the bonnet for the past 20 years.

hi i have a 1997 mazda bravo diesel and when i had the aftermarket safari turbo fitted
it was boiling my second battery which is right near the turbo on the left side of the bravo engine and it was so hot i could'nt put my hand on it

after a rush of the proberbial to the brain

i came up with a thought of a bonnet scoop then searched the internet and found a small b/scoop it only cost $65 size 30cm L x14cm W x3.5 H and and a slot hole across front 10cm's x 1cm deep this lets enough air in

i reluctantly cut a hole in the bonnet where the scoop airflow would blow onto top section of turbo down past the turbo and take the heat down the firewall and out underneath
the hairbrain idea works that was 11 years ago and still doing its job

have never regreted cutting the hole in the bonnet and painted the scoop same as vehicle and no one has really noticed it

wouldnt know if the guy is still in business but he at the time was in belmont w.a
and came up under bonnet scoops supplies when i googled
i dont know where you live but the idea will fix your problem
cheers
