How do I determine if the lead-acid battery needs to be replaced? As the battery has been used for a long time, the capacity of the battery will slow down. When the battery is lowered below its rated capacity of 80%, the lead-acid battery begins to appear aging, and the battery can be scrapped at any time. Usually, it is clearly filled with electricity, but it will quickly be used. But users cannot be more battery, because this is probably because of the machine. So we must be a battery that is suspected of a fault.There are two types of lead-acid batteries.
One is a conventional discharge method. This method is that the battery must be charged. If the battery is discharged from 1/2 rated cold start current value at normal temperature for 15 seconds, the voltage is below 9.6V, which should be replaced. In this test, the tester is required to train, the responsible heart, and the reaction is sensitive.
The second is to use a conductance instrument to detect. The working principle of the conductance instrument is to determine its chemical reaction capability by measuring the surface of the plate, and the change in the battery capacity is inferred by the change in plate changes. This method is relatively convenient, and the detection is relatively accurate.
