Moving battery to the boot

    I've been toying with the idea of moving the battery to the boot for better weight distribution and to clean up the engine bay, I have a battery tray and was going to fix that to the floor of the boot and clamp the battery in, however my bit of searching has turned up a few folks who say the battery should be in a sealed (or vented to outside) box.

    Is there a real world risk of a hydrogen explosion inside the passenger compartment if I just leave the battery sitting on a tray?

    Mercedes fit the battery under the back seat in some models.

    I can't see how moving a 20 kg battery will affect weight distribution in a road going car. 100 lts of petrol weighs about 90kgs (always going up and down), and passengers would have a much bigger affect that moving a battery, but that only my opinion.

    as do Porsche in the 968, they even have a counterweight on the other side of the boot. :)

    Can't see how it will make a difference in real life though.

    If you're worried about it, fit something like an Optima redtop gel battery....I'd also consider fitting an isolator switch right beside the battery if you're going to retrofit cables to to the engine bay.

    Battery boxes are easily available from Caravan and Marine dealers. Keeps your battery, spillages corrosion etc contained and also means your connections don't come in contact with things in the boot. From about €20.

    my alfa 164's had thier batteries in the boot. handy for jump starting other cars on the motorway but thats about the only advantage.
    the alfa had a vent hidden behind the rear bumbers to allow the gases to vent.

    You can get a sealed battery designed to go in the boot. Not sure of cost vs a normal battery. Been meaning to do that with my daily driver for a while now........

    I don't think the risk is of explosion but the gas is toxic?

    They may be an issue with voltage drop with long cable runs. I know it was a problem with the first Escort Twin Cams who had a standard escort battery in the boot and the voltage drop resulted in slow cranking speeds, but that was in 1968....

    Motorsport Regs say that for a wet battery (lead acid type) they must be in a sealed container if within the passanger compartment. For drycell batteries they don't have to be, and they can be mounted on their side. I imagine that they would be a good model to follow.

    Have a look on Demon Tweeks for battery boxes & dry cell batteries. Personally, I'd be getting a slim dry-cell battery, leaving it under the bonnet and getting a small chrome plate with the galloping horse on it to cover the battery.
