Relation between the Life of YUASA Battery and Environmental Temperature

Relation between the Life of YUASA Battery and Environmental Temperature
Generally speaking, the service life of maintenance-free lead-acid batteries will be halved if the working environment temperature rises by 10 degrees C at 25 degrees C. When YUASA battery is in a floating state, it needs to be compensated by lowering the floating voltage. The compensation coefficient of ambient temperature is 1 degree C, and the floating voltage of YUASA battery (2V monomer) is reduced by 3 ~ 5mV. Periodic discharge is very dangerous because if the battery is dead or AC power distribution fails, the battery becomes ineffective.
For the case of deep discharge and then call, the method of "constant voltage limit" can better charge the battery pack. The charging method and parameters are mainly determined by the characteristics of the battery. When the main power supply is cut off, the battery pack supplies power for the load and monitoring module. The monitoring module monitors the parameters of the battery pack and performs the corresponding calculation. After the power supply is restored, during the soft start of the rectifier, the parameters of the output voltage and current (current limit point) of the rectifier calculated by the monitoring module are transmitted to the rectifier, and the rectifier is executed according to these parameters. In this case, the rectifier needs to have stepless current limiting function in order to obtain the best battery charging current. For the case of shallow discharge, it should be charged or floated directly according to the actual situation. As for the daily management of batteries, I would like to make a statement that periodic discharge is necessary to protect batteries. In my opinion, regular discharge is not only unnecessary, but also dangerous.
It should be noted that the temperature compensation function can only work within a certain range. YUASA batteries should be operated in an environment of 20-25 degrees C.
