Drive longer distances frequently, keep your car at a neutral temperature, and give it a good clean. It’s important to look for corrosion on your battery. You can even clean the clamps with baking soda, water, and a nonmetallic brush. Invest in a battery maintainer, to help you keep the battery alive during those crucial winter months. Batteries should recieve a top up charge every six weeks in order to be healthy, but excessive charging could actually shorten its life. A battery maintainer will help to monitor the battery voltage and automatically adjust the charge to avoid under and overcharging it.
