The battery on my 1.8 coupe keeps dying. i have checked the alternator and when the car is switched on it is at 14ish volts, so should be charging the battery. have charged the battery with a proper battery charger and stil it only holds about 10ish volts.
Does this mean my battey is dead and i need a new one?
Also there appears to be some residue around the negative battery terminal..that wasnt there before.
