Howdy team Clubsub,
Last weekend our BP5 Legacy developed a dead flat battery, no big deal it was less than a year old and under warranty so was given brand new replacement from auto store Wednesday, started car and ran for less than minute and confirmed all good. Had not used car since, then today went to start and AGAIN dead flat!
When I mean dead flat: the starter motor doesn't even click on turning the key, no lights on dash etc, our jumpstarter pack does nothing and C-Tek battery charger won't charge or even register as connected to a battery - it times out and switches off!
Now the odds of having two faulty batteries are slim, even more so with one less than a week old, so something in the car is draining the battery when the car is sitting idle. Nothing obvious, no doors ajar, no aftermarket electrics anywhere in car
Not a typical lockdown flat battery either: car was driven roughly every 4 days to deliver/collect supplies for a distance of about 10kms and up to 80kph for some of it, would have thought that's enough to keep battery operational.
Auto store said I can take it in for them to charge up Monday. Once battery is running, do you think I should take car to a mechanic or auto sparky? I'm thinking its more likely an electrical gremlin, so unlikely a part for mechanic to swap out.
Even better can anyone suggest what the problem may be?
Appreciate any advice and thanks in advance!
