As a key component of the power system, the battery resistance tester be tested and maintained every year, every quarter or even every month, and its test data needs to be analyzed on a regular basis. Under normal circumstances, the internal resistance of the battery is generally normal. The answer is not a fixed value. The internal resistance of different batteries is different, and there is no fixed value. The internal resistance may change with the use time of the battery. Bigger or smaller.
After Litai Power tested according to the battery internal resistance tester produced by our company: the internal resistance of the battery is generally normal. The conclusion about the internal resistance and capacity is: when the internal resistance of the battery is greater than 25% of the initial value (base value) When the time, the battery will fail the capacity test. When the internal resistance of the battery is greater than twice the initial value (base value), the battery capacity will be less than 80% of its rated capacity.
The battery internal resistance tester is a digital storage type multifunctional portable test instrument for quickly and accurately measuring battery operating state parameters. The battery internal resistance tester has passed online testing and can display and record important battery parameters such as multiple battery voltages, internal resistances, and connection bar resistances, accurately and effectively determine the battery’s good condition, and can be combined with a computer and special battery data analysis software Together they constitute an intelligent test equipment to further track the decay trend of the battery and give an alarm in advance to facilitate engineering and management personnel to deal with it as appropriate.
