Hey Guys, before I go out and buy a new battery, can you help me make sure that this is the issue?

I managed to flatten the battery the other day (forgot to turn the map light off :(). I got a couple of lads to push start the car, and off I went, car alarm blaring. Drove around for about 20 minutes to get some charge back into the battery, stopped and sorted out the alarm. Restarted and everything was fine. Went off up the M11 for 70 miles. Parked up at the festival and got *****xed :duffer::duffer:

Tried the start the car this afternoon to come home, and battery is flat again. Got a jump start and came back to London. For some reason the Hicas light came on (dunno if this is just coincidence).

Anyway, got home, everything fine. Just went out to get something from the car and thought, let's just turn it over. Result: nada. All charge gone in under four hours!

So, do you think it's just a knackered battery, or do you think there might be something more serious at work? I'm assuming the alternator is good, because the car works and the battery warning light hasn't come on.

And what battery would you guys recommended?

 

Ta,

Its either the battery or a current drain. If its the latter than you will have the same problems with a new battery.

 

You can test for drains by disconnecting the battery negative cable and with ignition off, place a multimeter between the cable and battery terminal and setting it to 10amps, Up top 30ma or less should be fine, anything over would suggest a drain.
