Sudden Battery Failure!

Thanks chaps, ordered the same battery again for pick up tomorrow. Only £68 and the last one has lasted 7 years, so worth another punt...

When my last battery died the AA man that came out said the new technology batteries can go suddenly, unlike the old style lead/acid which tend to tail off and give you plenty of warning. Could be sales bullsh*t but does seem to stand true.

0.5 volt!! Usually for it be so low something's dragged it down?
Would be worth trying to charge it.

My ctek charger won't touch it, doesn't even recognise it as a flat battery!

I ran mine down a month or two back and it's been poorly since. Massive Bosch Silver battery that's maybe 5-6 years old too; anything less would be toast.

Time for a new one. Keep your eye out for 45% discount at GSF every now and again.

7 years isn't a bad innings. I had a similar issue last year and tried to charge it but it didnt recover so I replaced it with a new Varta

Just checked, the battery is 7 years old, perhaps it has had its day....

My battery has suddenly died! I could not unlock the car last night with the alarm remote. I left it be, then took a look tonight. The alarm light has stopped flashing, so I opened the car with the key. Central locking did not work, but drivers door lock only unlocked. Key in ignition, nothing. Back seat out, battery measures 0.5v across terminals. It seems like simply a failed battery. It did get fully discharged a couple of weeks ago and I think it is about 5 years old.

Should I just throw a New battery in it, or is something more fishy going on?

I have had no electrical issues recently at all....

Cheers
