Flat Battery

Has anyone else has this problem... with a UK Spec Factory Alram

 

I leave my car for two weeks without the alarm on (Chained to a wall) and when I try to use it the Battery is dead, (1.75 v) only, so flat in fact the charger does not recognise it and will not charge.

 

Its a 12v 70amp Toyota Supra Special, form Toyota, (6 months old) What they recommended to me.

I have this problem as well, although mine will take charge when flat.

 

If it is really bothering you, get a bigger battery, like the Optima Yellow top or similar.

 

My Optima still goes flat - if it's been 2 weeks I take the jump leads to the garage, just in case. 3 weeks? No point going without them.

When I bought my car the guy selling it had the alarm disconnected as the vehicle had been standing for a few weeks.

I was a bit concerned about this and took it to the Toyota dealer when I got it back home.

The guy there said no problem leaving it for longish periods with the alarm set.

Oh dear wrong...................again:)

Hi All,

 

Thanks for the comments, I got a Varta one from Cafco in bracknell, (Open Sunday!) for £67.35 all in.

 

It starts much better now, but it still new (Will see what its like in a years time)

 

Going to Toyota tomorrow, and asking them why this batt failed!!

 

I also emailed a guy at http://www.knightbatteries.co.uk and told him my problem, asking about the Optima Yellow, he recommeded the Hawker Odyssey range PC1200 http://www.knightbatteries.co.uk/products.htm

A bit pricy, but if this new one fails after a year, I'm getting one of these.
