Well the 85ah battery has finally died. Shortened it out, while putting clips on with a female 12v, to put my 150w inverter in a couple of times. Solved that by insulation tape aoround the corners of the seat base. Anyway, another time left the habitation swith on and not even the light would work. Been out today and checked the voltage 12.78v. Put the habitation switch on and a single light, kept my meter on and dropping voltage of .02 of a volt every 5 seconds. within a minute or so down to 12.38v. So holding it's charge but soon as anything is on :Sad:. Dont even know how old the battery is anyway, could be the oringinal So a new one in order, £70 for a 110 ah will have to fit the bill.
