Answer 1

If your battery is loosing it's charge overnight then there is a few things that can cause this. The most common cause is a battery that has a dead cell. The way to find out is to park the car in the evening and disconnect the negative battery cable. When you get up the next morning reconnect the negative cable and see what you find. If the battery has run down then the battery has a dead cell and needs replacing. If the battery is fine then you know you have another problem. More than likely you have a light that is on or a relay that is stuck. Check all the lights on the vehicle. Interior, brake lights, under hood, trunk, glove box, etc. If none of the lights are one then start checking for a stuck relay.
