What voltage should my starter battery sit at ?

[JumpShip]

With the ignition off my battery is sitting only just above 12v and drops to 10 something when starting.
With the engine running its 14.2 /14.3v which is what I'd expect.
Current batt is about 6.5 years old .
Van gets a good run on a weekly basis , not sat around .
What do you reckon ?

On the diminshing stages.

You'd get a few more years from it with an AMT12-2!

How much use do you get out of it before it needs charging though? Can you get a night or two away out of it?

12.2v - 12.6v resting.

Down to 9.0v starting.

13.6v - 15.0v engine running.

My newish 95Ah battery sits at 12.25V with the AMT12 keeping it there. This is around 80% SOC for an AGM. Which is where a stop/start battery should be.

It's my starter battery not leisure .

It's not let me down yet but just seems to have lost a little 'sparkle' when turning over .
We're away for 90 days in spain in a couple of weeks time so I'm trying to crack off all those little jobs .

I would get a new battery in there! You've only got to be stopped for a 2/3 nighter for the battery to let you down for the first time with the doors opening and closing several times draining the starters powers. Or make sure you're carrying a noco boost. Unless you're on EHU of course, with something to charge that starter.

No need to carry one, all I do is start other peoples vans! Never needed it myself, but the day I leave it at home I will.
