The next thing to consider is the alternator. The purpose of the alternator is to keep the battery charged. Obviously if this is bad your battery will drain quickly.
A third reason for your battery to be draining quickly could be a poor or intermittent ground connection (see picture below). This can cause charging problems including not charging at all.
If you continue to have a battery issue there is most likely something within the vehicle that is continuing to run after the key is turned off. Even though your vehicle may be turned off, the battery power is still being used for your cell phones, tablets, your car’s security system or remote start capability that is left plugged in. Even your vehicle’s computers (that’s right, more than one) use the battery to retain their memory.
