Battery life ?

[blade7]

The battery on my 91 944 is around 9.5 years old, still starts the car ok but I'm wondering if there would be any benefit in fitting a new battery ?

The 944 is a fair weather toy that rarely does short journeys or gets used in the wet or after dark, I just wondered if an old battery could affect the ignition. The battery in my Audi A4 did around 9 years before it died.

Are you able to check it with a multimeter? Or what's the impact to you if you get stranded with a flat battery one day? That will give you the answer...

Yes, and I've got RAC...

Battery buying is still a bit of a lottery, I have 1 on a Lotus 7 replica that is still good 7 years later without trickle charger but have bought several batteries for tin tops only a few years apart

I'm surprised it has lasted as long, I had a Cosworth years ago that I hardly used and batteries only lasted 3 years on that.
