What factors are related to the service life of lead-acid batteries?

1. The ambient temperature has a greater impact on the battery. If the ambient temperature is too high, the battery will be overcharged and gas will appear. If the ambient temperature is too low, the battery will be undercharged, which will affect the battery's service life. Therefore, the ambient temperature is generally required to be around 25°C, and the UPS float voltage value is also set according to this temperature. In practical applications, the battery is generally charged in the range of 5°C to 35°C. Lower than 5°C or higher than 35°C will greatly reduce the capacity of the battery and shorten the service life of the battery. 2. The depth of discharge has a great influence on the battery life. The deeper the discharge depth of the battery, the fewer the number of cycles it uses, so you should prevent deep discharge during use. Although UPS has a battery low-potential protection function, generally when a single battery is discharged to about 10.5V, the UPS will automatically shut down. However, if the UPS is under light-load discharge or no-load discharge, it will also cause deep battery discharge. 3. During storage, transportation, and installation, the battery will lose part of its capacity due to self-discharge. Therefore, before putting into use after installation, the remaining capacity of the battery should be judged according to the open circuit voltage of the battery, and then different methods should be used to recharge the battery. The storage battery that has been left on standby shall be recharged every 3 months. You can judge the quality of the battery by measuring the open circuit voltage of the battery. Take a 12V battery as an example. If the open circuit voltage is higher than 12.5V, it means that the battery has more than 80% energy storage. If the open circuit voltage is lower than 12.5V, it should be recharged immediately. If the open circuit voltage is lower than 12V, it means that the battery stores less than 20% of the electric energy and the battery is unusable.
