Starting issues
« on: 24 June 2019, 13:44:51 »

Hi, don't use the Omega much so used to flat batteries, this time is different.

Went to start, dead battery. Battery was new 18 months ago. Charged the battery for 24 hours, started no problem, I have battery/alternator tester and all showed good. Next day won't start, but the battery shows a green light suggesting it's still charged. Have double checked for lights left on etc.

So bit puzzled by this. Unless the battery is a dud what could it be? Thanks.

It's a knackered battery. Leaving them connected and discharged kills them very quickly. Get it drop tested, but that's just to confirm the fault.


Best thing you can do with the condition sensor is to stick a bit of tape over it - they're not helpful at all

As suggested, a battery of that type is damaged as soon as its discharged. Left discharged for periods (more than a couple of days), its severely damaged.

Agreed, the little green ball gets stuck at the top so will never be able to show a flat/unusable battery.

Get yourself a Ctek type 'smart' battery charger & leave it connected to your car's battery  :y

(assuming your car is within reach of a mains socket)

Also it's measuring just one out of the six cells. One or more of the others can be faulty/shorted/sulfated and misleadingly you still see green.
