Electrical gremlin, possibly battery problem

[nabsim]

A starter bat below 80 % wont turn a engine over for more than about 10 seconds if at all, may not be as knackered as you think.

Trev I know that with the 3x90ah batteries connected I barely got 24 hours and that was taking them below 12 volts. That’s from a full charge via EHU and vans mains chargers more than 24hrs. My daily usage it 65amps so I should have safely got double that, just. When new I was getting over 2 days.

The battery’s won’t be completely buggered but they are for my needs, looking at the above the best case I suppose may be around 75% capacity and they certainly charge and hold charge well when just a lamp is applied. I wouldn’t have put one on as a starter if they were completely shot. Horses for courses again, would probably work fine for a low power user for years
