The first low temperatures proved many drivers, the importance of a proper battery condition. To assess the condition of the car "power plant" in amateur conditions, it is worth getting the right tester. It allows you to control the state of charge of the cell, correct operation of the alternator, as well as the correct operation of the voltage regulator. Especially with so-called maintenance-free batteries, where it is impossible to check the charge level with an aerometer, such a measuring device is simply irreplaceable.
Corresponding states are quickly and legibly presented on light-emitting diodes of the LED type.
The price of the tester is approx 45 zloty.
