Ahh, but did it leak? ;o)

good point --- I don theen so ---ed

Hi,

Maybe leak was wrong term to use, as in modern batteries there is no fluid sloshing around, therefore if punch a hole in the side nothing will flow out and, if you have avoiding damaging the plates, then the battery will still work.

The thing with modern batteries is that, although they are often labeled as 'sealed for life' this is not strictly true. All of these type of batteries have the potential to produce gas, this gas can build up enough pressure to turn a regular shaped battery into the shape of a rugby ball, (american football for our friends across the pond). Because of this every battery I have ever worked with are fitted with pressure relief valves on each cell. On car batteries these are usually hidden under labels or a blanking plate. If the battery gasses this can then condense and the resulting fluid is very corrosive.

My original post was just meant to be a reminder that these batteries, whichever way round you fit them, are not fit and forget, easily done when they are tucked away under a board in your boot.

On a more positive, no pun intended , note having looked at Odyssey's website I noticed that they are produced by EnerSys, these are one of the better manufacturers of batteries, their spec also shows that the plates are 100% lead, which is another good sign of a quality battery.

Hi Guys,

Found these pictures of some batteries we took out of a customers system a few years ago. The batteries were over ten years old and had never been checked since they were installed. Eventually they got the bad smell to the battery cabinet and called us in

The cabinet they were fitted in had to be dismantled to get them out, after which we would normally get them apart by dropping them onto the floor. These had to be carried out as they were so fused together we could not seperate them.

My old S4 battery was located in the boot and my S1 is behind passenger seat.
I'm just curious about S2/3. Where were their batteries placed?

AMA

S2's were still behind the seat. S3's at least here in the states the battery was in the boot.

Salut

I was going to joke that I don't think you'd get that lot behind the passenger seat.

More curious though is: did the batteries still work? Batteries get hot when they're used so packing them like that may be against theur specs...

Hi Vernon,

No the batteries were knackered, internal shorts had caused them to overheat and the pictures show thee result. These fitted into a cabinet which had three battery strings each made up of four individual batteries all fitted next to each other, common system and within spec.
