Influence of ambient temperature Hercules batteries 12V65AH battery a longer life can be obtained at 25 ℃ environment [1]. At elevated temperatures, the battery plate corrosion will increase, while consuming more water, so that the battery life is shortened, the long run if the temperature rises 10 ℃, life was reduced by approximately half. VRLA battery capacity changes with temperature changes, 25 ℃ when the battery capacity is 100; in the above 25 ℃, 10 ℃ for every increase battery capacity will be reduced by half. Therefore must be carefully adjusted so that a reasonable battery discharge current based on the actual temperature changes, while controlling the temperature of the battery compartment to keep the good within 22 ℃ ~ 25 ℃. 2.2 The effects of prolonged overcharging overcharge condition, the positive electrode due to oxygen evolution reaction, water is consumed, h + increases, leading to increased acidity near positive electrode, accelerated grid corrosion, so that the battery plate grid thinning accelerated corrosion, which reduces battery capacity ; at the same time increase due to water loss, allow the battery dry in danger, thus affecting the battery life. Operating temperature range discharge: -40 ℃ to 71 ℃, charging: -23 ℃ to 60 ℃ (application temperature compensated voltage charging) Recommended operating temperature range of 23 ℃ to 27 ℃ float voltage temperature averaging 25 ° C, the 2.25v / c to 2.30v / c VDC recommended maximum charging current of C / 5A (20 hour rate 1/5 times the current capacity) were charged, and when the charging voltage application cycle average temperature of 25 ° C, 2.4v / . c to 2.47v / c VDC maximum AC ripple (charger) for best results, we recommend the float voltage fluctuations 0.5% RMS or 1.5% of the peak - peak (PP), the maximum allowable AC ripple float voltage = 1.4 % RMS (4% PP), the maximum allowable AC ripple current = C / 20 A RMS self-discharge at 25 ℃ environment can be stored for 6 months, and then require a refresh charge. If stored at higher temperatures, refresh charging interval to be shorter.
