12v Battery sudden death
Discussion
They do just die. Had it happen a couple of times.
Once, I drove 80 miles to the office in the morning, stopped for petrol, carried on and then tried to leave for a lunch meeting. Battery dead and needed to be replaced.
Another time, tried to start a car where the battery had been maintained on a conditioner with no problems and suddenly there was no charge... it was 10 yrs old though.
Cells become defective and won’t hold or take charge.

Never known this before.
Parked car up last night all fine and dandy, this morning, nothing, not even enough to recognize the key-fob to open the car, put on charge and saying 4.5volts, been on charge for 2 hours still 4.5volts.
Anyone seen this before?
Sounds like your battery has given up the ghost - how old is it? Did you leave something switched on overnight?

I managed to completely flatten my battery overnight once (the accessory socket was permanently live) by leaving something plugged in.
The AA came with a booster, started the car and battery charged up easily.
Had this years ago on my Dad’s Vauxhall Carlton (told you it was years ago!) Parked the car outside someone’s house when visiting, all was good. Came back two hours later and there wasn’t even enough go in the battery to unlock the doors via the central locking. Opened the drivers door on the key, opened the bonnet and the battery connections were all ok.
There was a mobile mechanic who I knew vaguely working on his drive a few doors down. Went and spoke to him and he kindly came and tested the battery, no volts at all!
Went to a car spares shop locally and bought a new battery, borrowed some tools from the mechanic and fitted it and the car fired straight up and was perfectly ok afterwards
Sometimes they just fail
