Operation and Maintenance of YUASA Battery in Normal Use

Factors Influencing the Life of YUASA Battery

1. Temperature

Temperature has a greater impact on the battery life, too high or too low will lead to a decline in battery life (high temperature leads to overcharging, low temperature leads to undercharging), especially high temperature, the impact on battery life is particularly obvious. Generally speaking, the ambient temperature should be controlled at about 25 degrees Celsius.

2. Depth of discharge

The effect of discharge depth on battery life is also very large. The greater the discharge depth of the battery, the less the number of cycles used. Therefore, deep discharge should be avoided as far as possible when using the battery. Low current discharge is easy to cause deep discharge.

3. Floating Charging Voltage

Because UPS batteries belong to standby mode of operation, they are normally charged in the state of power supply, and discharge only when power failure occurs. In order to prolong the service life of batteries, floating charging voltage should be set reasonably. Low floating charge voltage will lead to insufficient charging and irreversible sulfation of the negative electrode of the battery; high floating charge voltage will accelerate water loss and corrosion of the positive plate. In addition, batteries of different types, specifications and batches can not be mixed, which will lead to different floating charging voltages of individual batteries.

4. Charging Current

Charging and discharging currents of batteries are generally expressed in terms of C. The actual value of C is related to the capacity of batteries. For example, a 100AH battery, C = 100A. Generally speaking, the optimum charging current of maintenance-free lead-acid batteries is about 0.1C, too large or too small charging current will affect the service life of batteries.

5. Periodic Maintenance

YUASA batteries should be inspected regularly after using for a period of time, and corresponding maintenance should be done according to the power supply quality of municipal electricity. Where the city electricity quality is good and the power supply does not stop for a long time, the battery should be activated and discharged at intervals to prevent the battery from being in a floating charge state for a long time and its activity from deteriorating. The time interval can be half a year, and the discharge depth is about 30% of the battery capacity.
