Product Description

Battery Internal Resistance Tester

Product Introduction:

Currently, the maintenance of valve-regulated lead-acid batteries in China generally involves checking the battery's float charging voltage. Practice has proven that voltage is not correlated with capacity, as voltage only reflects the surface parameters of the battery. Internationally, internal resistance testing has been widely applied in the daily maintenance of batteries.

Currently, the maintenance of valve-regulated lead-acid batteries in China generally involves checking the battery's float charging voltage. Practice has proven that voltage is not correlated with capacity, as voltage only reflects the surface parameters of the battery.

Internationally, internal resistance testing has been widely used in daily battery maintenance, replacing the previous voltage check method. Because internal resistance reflects the internal parameters of the battery, it has been recognized as an important parameter for accurately and quickly judging battery health.

The conclusion regarding internal resistance and capacity is: when the internal resistance of the battery is greater than 25% of the initial value (base value), 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 below 80% of its rated capacity.

The battery internal resistance tester is a digital storage, multifunctional portable testing instrument that quickly and accurately measures battery operating status parameters. Through online testing, this instrument can display and record multiple sets of important battery parameters such as voltage, internal resistance, and connection strip resistance, accurately and effectively judging the battery's condition. It can also form an intelligent testing device together with a computer and dedicated battery data analysis software to further track the battery's decay trend and provide early warning, facilitating engineering and management personnel to handle issues accordingly.
