Precautions: (1) During the process of shaking the insulation resistance, the speed should be gradually changed from slow to fast, and the handle should not be slowed down, so as to avoid the pointer swinging too large and causing errors. If the pointer is found to be zero, it indicates that the tested insulation has a short circuit fault. Do not continue to shake the handle to prevent damage to...

The lead–acid battery was invented in 1859 by French physicist Gaston Planté and is the oldest type of rechargeable battery. Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, its ability to supply high surge currents means that the cells have a relatively large power-to-weight ratio. These features, along with their low cost,...

Internal resistance test: The traditional battery capacity detection method is to perform a complete set of verification discharge, that is, to connect the battery pack to the load box, and then discharge it until the cut-off voltage (no power) to verify the battery capacity, but this There are many hidden dangers and disadvantages in this method: a. The discharge time is long, the risk is high,...

Battery discharge rate Lead acid battery can be discharged either at a slow rate for long time or at a high current for a short period. For example, a 10Ah lead acid battery can be discharged at 0.1C rate and will give 1 Amps current for 10 hours. If the same battery is discharging at 1C, it gives 10 Amps current for 1 hour only. The discharge rate is linear on low loads. When the load increases,...

Battery and Cell A lead acid battery is composed of array of cells. This array of cells is known as Battery. A 12 volt Mono block battery has 6 cells (each gives 2 volts) but a 2 volt tubular battery has only one cell. The capacity of the battery to store charge is expressed in terms of Ampere hours (Ah). One Ah = 3600 coulombs. 1 Ah battery can provide 1 ampere current in 1 hour. The 100 Ah tubular...
