Why does the battery discharge rate affect the service life? ? How much do you know about this problem? ? Today, the editor of Zhengzhou Kanglida Electronic Power Supply Co., Ltd. will give you some information on this issue. I hope it will be helpful to you. In the future, you can avoid detours when using and purchasing.
Generally, the capacity of the 20-hour discharge rate is the rated capacity of the battery. If you use a discharge rate lower than the specified hour, you can get a battery capacity higher than the rated value; if you use a discharge rate higher than the specified hour, the discharged capacity is smaller than the rated capacity of the battery, and the discharge rate also affects the battery terminal Voltage value.
When the battery is discharged, the electrochemical reaction current is preferentially distributed on the surface closest to the main solution, resulting in the formation of lead sulfate on the electrode surface and blocking the inside of the porous electrode. In high current discharge, the above-mentioned problems are more prominent, so the larger the discharge current, the smaller the capacity given by the battery, and the faster the terminal voltage value declines, that is, the end-of-discharge voltage value decreases with the increase of the discharge current.
But on the other hand, it’s not that the lower the discharge rate, the better. Studies have shown that a long-term discharge rate that is too small will significantly increase the amount of lead sulfate molecules produced, causing stress to cause the plate to bend and the active material to fall off, and it will also reduce the use of the battery. life.
