Tips On How to Cure a Draining Battery

Mich Butler
If you have a problem with your battery running out of power when you are not using your vehicle you probably have a slow drain in your battery. These drains can be something of purpose, such as a clock that has to keep time, or something meaningless like a small short that constantly draws power out.

You may not even notice this problem if you run your car every other day. The reason for this is that the battery drains at such a low rate that your daily commute easily recharges the battery to its full potential every time you drive it. However, if you have a classic car, your battery might be dead every time you try to start it. Continually letting a battery drain will make it die much faster then it normally would.

To fix this problem there are several things you can do. The first and easiest way is to disconnect your battery every time you want to put it away. The problem with this is you have to connect your battery every time you want to drive, and disconnect it every time you stop. This can be a bigger head ache then you may think. Also you may think that you will take it out again tomorrow, but it rains so you do not get back to it for a month.

The best way to fix the problem is to see what is still on after you turn off your key. Once you have located this, either find a way to completely disconnect it, or rewire it to find a way to make it turn off along with the key.

An old wire that is directly connected to your battery is also a likely suspect. Replacing it may actually save you a lot of time trying to find out what is wasting your energy. Even if the wire looks like it is not accidentally grounding out there is a good chance it might be when it gets wet.

Another way to fix the problem, which I do not recommend is to put a switch in your car that has a direct path between your positive battery cable and the rest of your car. If you have a heavy duty switch you can flip it and turn everything that is draining your battery off, and then flip it back on the very next time you want to take a drive.

    I actually had this problem once. I took it to two different mechanics, and no one could figure out what was wrong. I ended up getting rid of the car. I wish this info was available then!
