Toyota Yaris 53 Plate
Two things really, the car is my Mum & Dads so I don't want them wasting money. The battery is discharging itself very rapidly. we re-charge it and it can go weeks without a problem, no dimming, laboured starting etc, and then suddenly discharges overnight.
The alternator light isn't coming on but even though the speed of the discharge seems to rule that out.
Nothing is being left on either. I've tested the battery & it says it's ok even though it's the origional & therefore coming up to 10 years old.
My question is this; Is this common if so what is the cause, and I have been given a battery that has never been used. It is a different size but surely if it fits in the battery bay and bolts down it should be ok shouldn't it?
And finally Cyril, do I have to re-set the radio code or can I get away by doing it without breaking the circuit using jump leads?
Many, many thanks.

So be prepared for a new one. Some items that drain a battery and are overlooked are the interior light being left on, the boot light being left on and the radio. Also the alarm sytem uses electricity.
The charging light will go out of the alternator is fine, and do the lights dim and brighten as the car is revved up?

For what its worth my 10-y-o was doing the same. I managed to keep it going using a battery booster but eventually died completely. RAC man charged me £98 for a new top grade Exide battery which he said was £3 more than Halfords. Later found the same one on the net for under £70. Should have change it much sooner.
