Car Battery Life

[gness]

My car is ten years old....the original battery lasted until I left the interior light on about two or so years ago.
The chap who came out said it wasn't holding a charge now so he started it and followed me to Halfords where I bought a new one.

That one lasted about eight months til I left the light on again....all this searching for my lost mobile in the dark does it.....

Again the battery wouldn't hold a charge so I had to have a new one. The chap in Halfords said bring the eight month one in and he'd check it but it was usually what happens when a battery goes flat.

So, before I fork out for a new battery, is it normal to need a new battery each time...or should this one charge up?

I no longer use any interior lighting........☺

Thanks Gx

Okay.....do you know.....I think car batteries are a bit like men.....x

Electrifying - but in need of a bit of basic care?

Fine and sparky with plenty of attention but ignore for a little while... and they go flat and lifeless....

Use it or lose it.

The older lead acid batteries did no harm when flattened but modern calcium ones will expire.

Thanks, Mjwman.....certainly appears to be the case, but why? Seems a step backwards to me....other than someone is making money.

I did find the guarantee for the last one....well inside but doesn't cover letting the battery go completely flat.....so I've bought a battery charger I can leave on while I'm away.
It has a five year guarantee....let's see what I can do to that which won't be covered.....☺
