Any car owner would want to make the most out of their car's battery. For one, they don't exactly come cheap and maximizing their service life is a great way to save money. Maintaining your car battery well also means that you won't have to keep relying on jumper cables (which is a good thing, especially if you don't know how to use jumper cables).
The top four tips for maintaining your car battery are easy to do but they'll go a long way in making the most out of the battery's power.
1. Park your car in a garage
A thoroughly insulated garage will help keep your car warm during cold weather which will help preserve your car battery. Don't invest in a heated garage because they're known to hasten the rusting process of cars.
2. Keep your battery clean
A dirty, greasy battery encourages a chemical process called oxidation which breaks down parts of the battery and will weaken the charge. Remove the clamps (don't forget to turn off the engine) and clean away any grease, dirt or corrosion (white smudges) that you see sticking to the battery with a clean, lint-free cloth or an old toothbrush. You can also use petroleum jelly to help loosen up old deposits.
3. Insulate your car battery
Even if you can't park your car in a garage or if your garage isn't insulated well enough, you can simply insulate your car battery. Car battery insulation is easy to install (it's like an adhesive sleeve that is slipped on) and you'll find it at most car stores or at your auto repair shop.
4. Secure the battery
A loose battery is bad news. It could tip over, hit other car parts and break, and the acid might spill over. Make sure that it is secured well and that the battery tray is kept clean.
Battery maintenance can be part of your regular car check-up services at a recommended auto repair shop. Make sure that your car is in tip top shape by having it regularly maintained by an auto repair specialist.
