Have had battery replaced twice ! when i initially tried to start car there was no noise off it at all not even engine trying to turn over ! Afterrepeated attempts there was a clicking sound ! Have brought car to a mechanic before and he said i must have left the light on ! i made a point of turning everything off every time and it happened again and he spent a full day checking it over but couldnt find anything ! also have had a few "sluggish starts" with engine turning over but being very slow to start. usually happens if i leave the car for a day without running it ! Any advice or solutions would be greatly appreciated.

Have you had an atermarket alarm or sound system fitted on the car? It sounds as though there is a large current drain on your battery occuring when its switched off. Either that, or the alternator isnt charging your battery. I would have thought the mechanic would have checked the charging system when the new (assuming they were fine) battery was fitted. To check for current drain, take a standard multimeter, set it to the ampere/current setting and then place both probes into the main earth lead. Any reading greater than 2 amps would indicate something draining it, a boot light perhaps. Next step would be to locate the auxillary fuse box and individually remove all fuses for ancillary components; radio, courtesy lights etc. until the current drain drops. There's your problem.
