Is there anyway to do this? I have installed a new battery, 3 months ago, and within a week I'd say, the Patrol seems hard to start in the mornings. Like the battery is dead. It doesn't get driven much, usually sits on a trickle charger, Ctek MXS10, but lately my daughter has been driving it and she's noticed it also.
Upon starting the Redarc volt gauge will drop down to below 12V, where it usually won't.

I have the standard leccy tools, DMM, battery load tester, (which I'll try this first, and maybe get the old hydrometer out and test each cell) But nothing flash.

I'm also wondering if the starter motor could be giving these symptoms, it is 8 years old.

Cheers.
