Fiat Uno (Again) Battery draining - wonderwheels
any ideas???. Car has been lying for a while. Took battery out as a "jump start" didn't work. Fuly charged battery with a charger. Refitted, but still not enough power. Used jump leads and got car started. Took for a run and turned off and on a few times. Went back to car today and nothing. Battery flat. Nothing was left on. All cells are OK. Battery gone???

Get the battery tested off the car?

If it's an old battery the capacity will be down.
They can also flatten themselves with the sludge in the bottom, which used to be on the plates.. there was a thread here recently about battery life.
