Acid Gas

I installed an AGM battery in the rear cabin (anchored, against luggage cage, thanks for checking).. I dont use my car much, sometimes idle for a week or two as I have a bicylce for commuting.. I opened my tool box after a few years of sitting in the back, and the tools had badly (severly) rusted - the spanner rachets all stuffed, and the plastic box filled with a rusty dust. caked on the interior up to about 3cm.

The metal zips on my recovery bag are all rusted closed as well.

I guess it has the be battery gas in the floor of the rear cabin. The battery is AGM so I thought (and have read) it would be fine..

This a common problem? Cheap AGM battery? Car sitting still for 2 weeks at a time allowing has build up?

After my trip on the weekend I will be removing the battery and only reinstalling when I do a trip.

I'd love sometone to tell me that it has nothing to do with my setup as it is pretty sweet.

Thanks

Are you sure it didn’t get wet?
My 150 was detailed before I picked it up and all that stuff was soaking wet from their cleaning exercise. Tools were on the way to rusting.
I don’t think they realised what was behind the covers when they got stuck into it.

That looks more like its been wet. Possibly heavy condensation from a battery charging and being warm.

Thanks both. The metal zip corrosion is sig less, and could be cheap. So far no one is voting for "Get the AGM battery out of the back before you die" and think that there is a more benign explanation.

Suggest having a read here, it puts it into more easy to understand terms. An AGM produces Hydrogen gas when charging, and can leak in some cases.

I'm not a fan of batteries in the cab even AGM's etc, "anchoring" them is a big part, in a rollover a loose battery would be like the ball bearing in a spray can

then there is eleccy fire side and finally gassing

they all gas when they charge, i understand a AGM or SLA "recovering" the gasses but they have a relief valve that allows them to vent when pressure is to much to prevent them from turning into a Grenade

been in a lot of Toyotas and the Majority have a dedicated Siamese battery locations either side of the radiator for left and right hand markets, most have had one side spare

its funny the "authorities" want us to use static rated d shackles tor a dynamic shock load application when we tow and dont care that the safety chain is galvanised and welded that both not rated

BUT

we are allowed to put anything inside the car we want
