DC screen maintenance-free lead-acid battery pack how to charge, discharge?
DC screen debugging, connected to the AC power supply test AC dual power switching device is working properly, dual power switch device under the port voltage is normal. After the AC part of the test is normal, close the AC module of the charging module in turn to observe whether the module starts normally and measure the module output voltage and polarity. After the charging module starts normally and the output voltage and polarity are correct, turn on the battery switch and the bus switch to measure whether the voltage, polarity and polarity of the battery switch are correct, and observe whether the voltage meter is in the direction. turn.
Commonly used rechargeable batteries In addition to lithium batteries, the lead-acid battery is also very important to a battery system. The advantage of the lead-acid battery is that the electromotive force is stable when discharging, and the disadvantage is that the energy (energy per unit weight) is small and corrosive to the environment is strong. Lead battery operating voltage is stable, the use of temperature and the use of a wide range of current, can charge and discharge hundreds of cycles, storage performance (especially for dry storage), low cost, and thus widely used.
Discharge: disconnect the AC, so that the battery load for the power supply, pay attention to discharge can not be too deep, otherwise the battery will have irreparable damage. Charging: After the battery is discharged, turn on the AC point and let the charging module charge the battery.
