    flat battery problem

    alrite guys, so i have a problem when i leave my car for more then 3 days the battery goes completly flat but its fine when i use it every day or every 2days. i went to kwik fit and a motor factors and they both said my battery was fine and the alternator was fine. could there machines be wrong? i have a noise coming from the fan belt wich sounds like crickets and it went worse when i put a new belt on. any ideas

    cheers

    If their tests show it's fine the next thing to check is the current drain. As little as 0.2 amps will flatten a battery in the time you say

    Any aftermarket electrical bits fitted to your car?

    Do you have a amp meter to measure any current drain?

    No.......

    Things like that could be causing your flat battery problems

    I'd disconect the main power for the amps and powercap at the battery via the fuse every time you leave it to see if you still suffer from flat batteries
