Label: Battery charging current and voltage settings. There are two ways to use the battery: recycling (that is, a cycle of discharge and charging), and floating charge (mostly used for UPS power). The charging convenience of the two is different, but if the setting is not correct, too large or small current will be detrimental to the battery life. Let's take a look at how we design the charging current and voltage of the battery for recycling: 1. The charging voltage of the recycling battery should be controlled between 14.5V-14.9V, and the charging current should not exceed 30% of the battery capacity. The best is Charge at 10%. 2. Floating charging batteries need to be supplemented or equalized after installation and before being put into use. After the battery is discharged, it should be charged immediately. When the battery float voltage is lower than 2.20V/single cell, the battery should be charged in equalization. The charging current limit value is preferably 0.1-0.2C10 (A). The floating voltage of the battery refers to the charging voltage value at an ambient temperature of 25°C. When the temperature difference exceeds 10, the floating voltage must be corrected, otherwise the battery will be damaged. When the ambient temperature rises by 1℃, the voltage should be reduced by 0.003V/single cell; on the contrary, the float voltage should be increased by 0.003V/single cell. When the load variation range is 0---100%, the charging equipment should reach 1% voltage regulation accuracy .
