I'm suspecting that my Corsa B has a dud battery but I want some second opinions.. before I rush out and buy a new battery.
History: In the summer the car wouldn't start after it had been sitting around idle for a couple of weeks. I managed to jump start it with my Astra in the end.
Now after the recent cold snap it has been idle for about 3 weeks (we didn't need to drive it you see) and again it won't start now.
But this time I can't even jump start it back to life.
The lights are very dim and the engine has no turnover whatsoever.
The alarm is also dead.
A couple of Q's:
1) These are all the tell tale signs of a faulty battery, no?
Or should I have it checked over in case it could be something else? Does anyone do free battery checks?
I wouldn't want to rush out and buy a new battery and then find out it wasn't simply the battery that was at fault you see.
2) When I recently tried to jump start her I was on my own so I simply connected the jump leads between the two cars and tried to start the Corsa without someone revving the Astra at the same time. The Corsa didn't start. Is it essential to have the 'donor car' revved up when jump starting a dead car?
