In small and medium UPS power supply, sealed lead-acid batteries are widely used. Proper battery maintenance is the key to extending UPS battery life. For this, this should be done:
1.It is strictly forbidden to over-charge the battery pack of the UPS power supply. Overcurrent charging can easily cause the positive and negative plates inside the battery to bend, resulting in a decrease in the available capacity of the battery and damage to the battery.
2.It is strictly forbidden to over-voltage charge the battery pack of the UPS power supply. Overvoltage charging will cause the water contained in the electrolyte in the battery to be electrolyzed into hydrogen and oxygen to escape, thereby shortening the battery life.
3.It is strictly forbidden to over-discharge the battery pack of the UPS power supply. Over-discharge is easy to sulfate the surface of the inner plate of the battery, resulting in an increase in the internal resistance of the battery, and even the phenomenon of "reverse polarity" in individual batteries, causing permanent damage to the battery.
Buy branded batteries from well-known and large companies. Batteries are generally provided by professional battery manufacturers. Different brands and manufacturers produce batteries of different quality and price. Well-known large enterprises have large scale, strong technology, good after-sales service and guaranteed battery quality.
