The performance of UPS batteries is very superior. In normal times, you should maintain a suitable ambient temperature, charge and discharge them regularly, and replace spent/bad batteries in time. The following mainly shares the characteristics of UPS batteries.

After the UPS battery has been used for a period of time, the UPS battery will experience different degrees of loss. In order to save maintenance costs, some users will replace the battery with larger loss with a new one. However, many users do not know that this approach will greatly shorten the service life of the battery. Because there are more chemical reaction substances in the new battery, the voltage at the battery terminal is higher and the resistance is lower. However, the terminal voltage of the old battery is low and the internal resistance is large.

In the use of UPS batteries, sometimes new and old UPS batteries are used in series. As everyone knows, this approach will shorten the service life of UPS batteries. Because the new UPS battery has more chemical reaction substances, the terminal voltage is high, and the internal resistance is small (the internal resistance of the new 12V UPS battery is only 0.015-0.018Ω); while the terminal voltage of the old UPS battery is low, the internal resistance is large (12V The internal resistance of the old UPS battery is above 0.085Ω).
