What is the meaning of float charging for intelligent three‐stage charger in battery charger?
Jul , 12 2024
Float charging: Keep constant voltage charging, the charging current continues to decrease, and the battery is charged with maintenance type. When the charging current decreases to the set value or the charging time reaches the set value, the red light of sufficiency will be on, and the time will be about 2H, charging 10% of the power. Ordinary chargers are old‐fashioned chargers, charging, whethe...

What are the meanings of deep discharge and excessive discharge of UPS batteries
Jul , 11 2024
Deep discharge generally refers to the discharge of approximately 80% of the rated capacity of a battery. After a period of use, there will inevitably be some active substances sinking in the power UPS power battery. If the active substances are not activated in a timely manner, it will inevitably have some impact on the capacity of the battery. Therefore, it is best to cond...
