Summer heat and winter cold are your batteries worst enemies. A little maintenance will go a long way to insure your vehicle will start even in the worst of conditions.
Your vehicles battery is subjected to a wide range of adverse conditions. Extreme heat and cold, alternator undercharging or overcharging all take their toll on your battery. Yet the only time we think about it is when we get in the car and we hear a loud clicking or buzzing when we try to start the engine. So we get out the jumper cables and get to work or the mall, but when we set out to go home, we hear the same noises. Now is the time we do some hard thinking about the battery.
