*Tick Tick Tick*
The car wont start.
Thankfully, you were able to get a jump from your neighbor. It was just drained overnight, right? You and your family drive to your recreation destination and have a good time. When it comes time to leave, everyone is exhausted and can't wait to get home.
*Tick Tick Tick*
Car wont start again. This is a bigger problem than just a little battery drain.
After having your battery inspected by a trusted mechanic, it is indeed a dead battery. Thankfully, it was only the battery and not anything else. Having your battery checked regularly can help avoid these problems.

| Replace When Necessary |
Of course, this isn't the only thing that can cause a battery to fail. There are a number of factors in what causes your vehicle's battery to suddenly drain or die altogether.
Other causes for battery failure (either draining or complete failure) are:
- Aging batteries - As a battery gets old, it slowly loses the ability to hold a charge.
- Inactivity - Inactivity can drain a battery of its power. Regular use will allow the alternator to charge the battery.
- Lights or other systems inadvertently left on - Dome lights, that little light in the glovebox that didn't turn off when it wasn't closed all the way, headlights, radio...the list goes on. Leaving these things on can slowly, but surely, drain your battery.
- Short circuits - Some faulty wiring can create loops in the circuit that will cause electricity to be continuously pulled from the battery, draining it completely. Higher gauge wire means faster drain. Even if your battery was recently replaced, you could be looking at blown fuses.
- Bad alternator - The alternator is the component that generates electrical charge to supply the battery as the vehicle uses up battery power. Your alternator could be overcharging the battery, or even undercharging. Having the alternator tested will let you know if the alternator is the culprit.
