Battery died AGAIN!

Post by Grendel »

Ok for the 2nd time this year after not using the car for week the battery was flat again?
Yet as soon as I stick it on the charger 8Amp it says fully charged in a few minutes but the fully charged never comes on when you slow charge it?

Battery is now back on the car it started with a bit of a splutter (possibly got a wet engine after all the wind and rain and the car not being moved?)

So sounds like the battery is on its way out and I was wandering where the best place to get a good heavy duty battery at a sensible price?

I replaced my battery at the start of the year; I did some research and opted for a Halfords calcium at £82.99. Not cheap but it was just about the only calcium I could find and the looking at the specs it was stronger than anything else I could find (600aH).

Reviews were very good for it and if you don't use your car everyday then very useful.

What are the differences between Lead Acid and calcium batteries besides the obvious? :-s

I think calcium holds the charge for longer so it's better for cars that are only used once a week.

As an obvious thing, have you checked the fluid levels in the battery?
I am going to live forever, or die trying!

They also have a far greater cold cranking capacity, so when its minus 10 outside, the starter motor still gets its share of Amps, rather than the customary relay clicking when the battery is old / on its way out....! :thumleft:

Thanks for the replies. And I’ll be in touch Nick when I need the battery.

Don’t think its battery level though since only plays up when it’s been left in cold/damp weather.

Unfortunately the battery problem will have to wait for the moment since I’ll be going in for shoulder surgery on Monday so probably wont be allowed to drive for a few months.

To lay the car up I presume I just disconnect the Pos lead and park it in gear with hand brake off under a cover while i'm not using it?
