It could be anything from a dimming dome light staying awake or glove compartment switch sticking on, to faulty aftermarket radio or alarm wiring. A certain amount of draw is normal – in the region of 25mA (milliamps) – but if you have 100mA or more being lost, something is up. It typically happens due to a short circuit that can be tricky to pin down. The result can often lead to a flat, caused not by a faulty battery or through something obvious like the headlights being left on. On occasion, a battery may experience significant drain long after the engine has been shut off.
