Been having problems with my 1 year old yuassa battery fitted last year. The car did 3000 odd miles with no problems, then sat a long time over winter and the battery was flat. Got it jumped,went for a run and it managed one more start before needing jumped again.

So I bought a trickle charger hooked it up and once full it was fine for 2 weeks then died again as i stopped using the trickle as the car was outside.

Charged it up again and i could smell a sulpuric smell. Drove to halfords to get a new one smell getting worse. Open the boot and smoke comming out the battery.

Had it been a longer drive it was so hot it could have caught fire.

Anyway brand new battery in.

Should I use the trickle charger attached to the battery or should it be attached tot he front battery jump point and the chassis?

It could simply be the voltage regulator on the alternator...supplying too much charge to the battery and over-charging it.

I had 2 batteries in the space of 100 miles when the AA insisted I buy a new battery to get me home as the old one was knackered. It wasn't the battery, as the 2nd one did the same 50 miles from home. Initially the AA said they'd charge me for a 2nd call out for the same problem - until I pointed out that it was their technician that misdiagnosed the issue.
