Dead car battery
Although car batteries last longer in the colder climate versus the sweltering heat, there can still be quite a few issues that occur when it comes to car battery failures—especially if you live in an extremely cold environment. Don’t wait until the last minute to save your battery with jumper cables this winter. Instead, save your battery’s lifespan by purchasing battery insulation. Some may say having a bigger battery is better but turns out having a smaller battery with an insulator can actually last you a longer period of time. It can keep the device warmer on cooler days, and cooler on hotter days. However, it’s smart to take care of your car battery and especially think about replacing after five years of use.

Sometimes the battery is actually not the issue when it comes to car failure—the issues could actually be your alternator. The alternator is responsible for charging your battery and takes the additional strain in the colder months. Your car will warn you with a red battery sign on your dashboard, so don’t assume it’s a battery issue quite yet. If this happens, test your alternator with a voltmeter. To test, your battery voltage should be between 12.5 and 12.8 volts with the engine off. If it’s below that, you should change your battery. If not, start the engine and check for increased voltage readings. Higher readings are good for your alternator (typically 13.5 or 1.5 volts), but if it doesn’t reach that it’s probably no longer good. The best thing you can do to avoid this is to check the levels of your car battery/alternator before experiencing a dead car early in the morning. Here’s how to replace an alternator if you need it.
