Lesure batteries

[Loch doun ventures]

Hi, I converted a swb sprinter a couple of years ago, I've wired in two lesure batteries to power the fidge & a few lights, the batteries now don't seem to be holding a charge i wired in a split charge relay to charge the batteries & between roadtrips i isolate the batteries from the fridge and the items consuming power so the batteries are still being charged when I've driving to & from work is it possible I've over charged them & knackered the lesure batteries? Kind regards ian

Did you remove the transport plugs........Ask me how I know this
Possibly the batteries weren't good quality? I've had battery in the past that faded within a year.
Our leisure batteries are charged separately via 2 large solar panels which keep the charge.

What’s the electrolyte level like? Are they dry?
