Righto chucked it on the charger and it now says its fully charged and has gone into float mode, its currently reading 13.28v which is a lot better than the 10.55 volts it had. So I guess this means I'm lucky to not have a bad cell ?
Going to chuck it back in the car tommorow and see how it runs.
Just to clarify a few things when I put it back in the car without it on what is the optimal volt reading ?
And with it switched on ?
And with it switched on and lights heater etc on load running ?
Any other check that can be made ?
Thanks
