Battery Draining problem
Hello All,
My battery drains very quickly just trying to find out why.
After I take my car out for a 40 minute drive the battery will be flat in less than 6 hours.
I tried using the key to lock the door so as not to arm the alarm but the same problem.
I tried disconnecting the bonnet sensor but the same problem.
I had a look into the cabin this evening and noticed that the light near the "p" on the gear lever selector was flashing and also faintly both lights near the roof opening button were flashing.
I will get my battery tested at halfords tomorrow morning.
Has anybody any idea of the problem?
Thanks

Doubt it. But always worth checking.andysat wrote:Alternator?
Is the roof properly closed? Don't know why that would drain the battery mind you.
Is the boot lid sensor working. boot light might be on.

Re: Battery Draining problem
I presumed as the battery was charging up after a drive that the alternator was working. The roof has not been opened since probably september. I only drive the car for 15 miles once a week so not sure if the battery has just deteriorated.
I bought the battery on Amazon fullfilled buy eurocars in May so I assume I can get a replacement - I don't have the receipt, but it's on my Amazon history, has anybody used just the Amazon history in this way?
I'll get it checked at halfords and go from there but I remember reading that bad batteries can created odd problems.

Re: Battery Draining problem
Does the light inside the cubby hole go off when the lid is shut? if not maybe the lever that should press the microswitch has broken off?

Re: Battery Draining problem
how old is the battery?
If more than 4 years old, ditch it.
Problems solved.
If you don't believe me, after a run, stop the engine. then durn back on, but don't start the engine. turn on lights and all accessories.
If the battery warning comes on in about 5-10 mins, the batteries reserve capacity has reduced due.
Try it.
I might be wrong.

Re: Battery Draining problem
Turn everything off , keys out ... Boot lid open ( put a screwdriver in boot latch and close it to turn light off) put an amp meter across the battery ....any more than 1/2 amp and you have a power drain .Start pulling fuses to identify which circuit . But like said above make sure battery good .... Most have a life span of 36 months then it's all down hill !

Re: Battery Draining problem
I bought the battery in May last year - but I think that the lack of driving may have hastened it's demise. I have already asked for a replacement through Amazon let's see where it goes. Also it was a Bosch S4 which I now realise have a high failure rate.
What batteries are people using these days?

Re: Battery Draining problem
Have you considered that your alternator regulator no longer works. Battery running down while driving is a classic symptom......

Re: Battery Draining problem
The battery is not running down while driving but after it's been driven. It's either the battery is bad or something is draining it?

Re: Battery Draining problem
do you have a volt meter you can attach?
how long does it take to drain to the point where it causes a problem?

Re: Battery Draining problem
What I will do today is take it for a drive then disconnect the battery and check the voltage and then check the voltage 5 hours later to see if the battery has lost its' charge. That should rule out a battery fault.
