Thread: DUAL BATTERY SII DISCO

Thanks for this it has helped heaps, i have got a few sheets of stainless in the garage so might get it ready.

Thanks Baz.

I think the other thing about the oddessey is it can be mounted on it's side meaning it is more likely gonna fit where others that need to be upright won't.

Hi Slunnie and Redback, I have know idea what battery was starting the disco, I only had the garbage box for 11 months and I hated opening the bonnet. For that matter, I hated opening the drivers door.

Enough of my bitching, I did put a second battery in the vehicle and during that installation I am sure that I did not see voltage levels of more than 14.2 but as I said, I hated that heap so it could have been 20 volts and I probably not taken much notice.

The second battery was a standard cranking battery and it was about the only thing in that s##t box that never gave me any problems, but as I said, I only had the thing 11 months.

When I was putting the second battery in, I was told that the Discos were having problems with the second battery, because of it’s location, were getting to hot and thats why I installed the stainless steel reflector.

Cheers.

if you can score a battery box off a jaguar series III they had a little fan in them for cooling the battery. cant say if they actually worked though.

Hi DEFENDERZOOK, if you fitted something like that wouldn’t you have to source the air from somewhere other than the engine bay?
Cheers

shouldnt be too hard to fit a bit of plumbing..dont need any large hiflo tubing, just enough to circulate the air around the battery.




also if a battery is fitted inside a vehicle it must be enclosed from the cabin and have a drain to the outside of the vehicle.
eg..a battery box with a hose(such as vaccuum hose) down through the floor. incase it leaks acid or gas it wont affect anyone in the vehicle.

An AGM type battery is the way to go for installing the battery inside the cab. Any of the fully sealed batteries could be used and then you don’t have to do any fancy fitting, just secure the battery so it can’t move and your done.
Now if you had a VW combi, your wouldn’t need to go to any special fitting and you could still use a standard cranking battery because that’s how they come from the factory. Don’t know how they pass safety laws
As far as the fan goes, I was just interested in how jag does it.
Cheers

Lead acid and lead calcium maintenance free batteries appear to be fully sealed but are not. They have a small vent to relieve any excess gas formed. They are not suitable for installation in a cabin area or in a non-vented space. AGM and gel are apparently safe and apparently do not leak. However, they do need to be properly secured for obvious reasons.
