Oil Changes and Tyre Pressures

Howdy folks! My name is Tony and this is my latest blog. For some time, I have been trying to think of what my new blog should be about. It was yesterday when I realised that the topic had been in front of me all along. The biggest thing I have learnt recently is how to service my car. I didn't believe in auto servicing. I thought it was the kind of thing people talked about but never did just so they seemed smart. Well, I didn't feel very smart when I broke down at the side of the road. The mechanic was kind enough to teach me all of the top tricks about how to maintain a car.

When Your Battery Fails Too Often, Something May Be Happening Overnight

If you've just returned from your auto-parts supplier with another brand-new battery, you may think that this is an all too regular occurrence. After all, if you've had to call in your battery warranty on too many occasions, you may be thinking that your car is the problem rather than the device itself. But what could be going wrong in this situation, and how can you fix it so you don't have to be on first-name terms with the store assistant any longer?


When more than one battery has failed before its time, it's likely that your car is requiring too much of the part. Certainly, the battery is designed to provide a big boost of power whenever you turn the ignition key, so you can click the starter motor into action and get on your way. It's also designed to deliver a "trickle" of power to a multitude of onboard ancillaries when the vehicle is not in motion. Indeed, the problem may lie in this latter area, in a phenomenon known as the "parasitic" drain.

In the Background

Certain components may still be active when your vehicle is parked up overnight. These may include a central computer, the cabin lighting system, an alarm, and various other electronic components, but the amount of power they use is very small.

Unwanted Harvesting

Still, it's possible that a component is harvesting power from the battery when it should not be and is wearing the battery down during those long periods when you're not in the vehicle. This is also known as a "vampire" drain in the industry, and it can certainly cause excess wear and tear. If you only use a vehicle for short trips on a given day, then the battery may not have time to recharge itself fully, and, in short, it'll need to do far more work than it should.

Fixing the Issue

It may certainly be possible to check for parasitic drain by using a multimeter, but this is a fiddly job and is not easy for someone who is not mechanically inclined. In this situation, it may be better for you to take the vehicle to a mechanic who will perform a full electrical service and test each circuit to see what is happening. If they discover a parasitic drain, they can take care of that so your battery should last much longer in the future.
