The operability of the device, which is "powered" from it, depends on the health of the battery, for example, a car battery. Therefore, it is important to learn how to identify battery malfunctions in order to extend their "life" and, consequently, the operating period of devices powered by them.
Necessary
Battery, special equipment, load plugs
Instructions
Step 1
Charge the battery as much as possible, and then bring the charge indicator to minimum. At the same time, keep the power and current indicator at a constant level. This requires special equipment.
Step 2
Record the discharge time at which the voltage reaches the minimum acceptable level.
Step 3
Compare the result of the received test discharge with the technical parameters of the battery.
Step 4
Measure the voltage of the battery under heavy load by using the load plugs. The voltmeter scale is colored in different colors. Based on the sector in which the arrow of the measuring device is located, you can conclude about its serviceability or malfunction. So, if the arrow is in the green sector, then your battery is in excellent working condition. If the arrow is in the red sector, then it's time to think about buying a new battery.
