batrery drains easy 2003 ford explorer eddie bauer

Have a 2003 Ford Explorer Eddie Bauer, with about 55,000 miles. I left the lights on for about 20 minutes and the battery was completely drained. Even the remote to open the doors wouldn't work. .

Just fine after a jump.

Seems like a short time for the battery to completely drain. Had been driving for 3 hours before leaving the lights one.


This is the second time since owning the car this has happened. last time about 1 year ago

If that is the original bat, it is about 4 yrs old, time for a new one. But check the terminals for corrosion, and clean/tighten.

I typically get a lot longer battery life than 4 yrs but it is important to reguarly check the water/electrolite level. You also might want to verify that the alternator is working correctly.

The chemical process by which a battery creates electricity slowly destroys the capacity of the battery. I would be looking at a replacement in the very near future to prevent becoming stranded on a cold winter's night.

The way to check the battery out by yourself is to pull the plug wires or disable the ignition system hook up a voltage meter to the battery and turn the key to start the engine while watching the voltage meter. If it drops close to on in the 10v range or low 11s with in say 5-10 seconds the battery is weak and needs to be replaced. A lot of automotive store have a load tester to do this while the battery is still in the car and some can check out your charging system at the same time.
