How to Test Your Car’s Battery

If your vehicle has started requiring a few tries to turn the engine over, it could be a sign that the battery may need some attention. The extreme temperatures of winter can be very wearing on the charging system. There are a couple of checks you can run to determine the health of the battery. The first is to fill the cells with distilled water if they are low. The next is to establish it has the proper voltage.

After connecting your fully-charged battery to a voltmeter, you should get a read of at least 12.6 volts. Reading it while the car is running is optimal at between 13.7 and 14.7 volts. Another way to establish a steady charge is to start the engine and turn on the headlights. If they’re consistently illuminated, then there’s no problem. On the other hand, if they appear dim, or change intensity as you rev the engine, that’s a symptom of the charge coming from the battery rather than the alternator. It would be a good idea to get it checked.
