Battery Issue ?

[mahatma]

Hi

My 172 has been sitting around unused for 2 weeks and refuses to crank unless jump started. It would appear to have it's original battery.

I left a cheap battery conditioner plugged in and after an hour it had its fill at 12volts.

This still isn't enough to start the car.

I was wondering whether attaching my older, more powerful charger, to the battery in situ would be ok?

It is rated 4-6 amps - it's quite powerful. But would this damage the Clio ??

I'm reluctant to take the battery out of the car and I only have 1 key.

Advice gladly received.

Cheers

I would say yeah its fine, im having the same problem at the moment, i connect the charger for a while then start the car with the charger still attached
