Life of car batteries

Battery life depends on the temperature. Often, high temperatures can affect battery life. It increases the corrosion of the plates and evaporates more malfunctions of the electrolyte necessary for the current. Long service life is especially important if you make many brief trips, which do not allow enough time for a full charge.

Make sure it’s a new battery!

Batteries lose strength over time, even when they are in storage. For best performance, you should buy car batteries that are no older than six months. Most products in the recent market have a year of manufacture identification code.

Some use a letter for the month (A for January) and a number for the year (6 for 2016). Other manufacturers use a numerical date.

How to extend the life of the car battery?

To extend the life of the battery to exceed the average of four years, which we talked about at the beginning, we have the following secrets for you.

  • Try to always park your car in the shade, especially in the hottest period. The buyers have to understand that the high temperature damages the battery.
  • Frequently measure the no-load voltage at the battery terminals and recharge it in this case. If after 24 hours of rest and the temperature is about 25 degrees, the voltage should be less than 12.8V.
  • Measure the voltage at the terminals with the engine running. After three minutes at 2000rpm and at 25 degrees, it must be between 14V and 14.4V.
