Does anyone have any info or views about Fuller, Leoch, and Advanced (ABS) leisure batteries?

[David and Judy]

I asked about Fuller batteries on a recent thread but although I got a wide range of helpful advice on batteries generally there was no comment on Fuller batteries.

I want to fit 2 leisure batteries in a very tight space under my drivers seat. With this size restriction in mind I have found batteries of a suitable size from Fuller, Leoch, and Advanced (ABS) in that order of preference. However I am reluctant to buy and install 2 batteries from names I do not recognise.

The batteries need to be relatively small to fit in a very restricted space hence the shortlist of names I have narrowed down to. I hope someone can share some specific feedback on the four battery providers mentioned above. Many thanks.

Had advanced in previous van but it was an agm which is a bit contentious but worked fine for me

Sadly there is no magic bullet as far as batteries go.
The physical size has a direct correlation to the capacity of a lead acid battery
You need a certain amount of lead surface area you see....

The only reliable way to get the same amp hours from a smaller battery is go LiPo.. Even LiOn units are not much smaller than lead acid amp for amp

Anyone claiming a high capacity from a small lead acid battery either has access to the same tech as Dr Who or is pulling some sort of fast one
