Vipow BAT0270 12V 26Ah Gel Battery

Vipow BAT0270 gel battery provides 12V voltage and 26Ah capacity. It is designed for both standby backup operation, such as in UPS systems, and cyclic use. It features a lifespan of up to 500 charging cycles for devices with regular discharge. Low self-discharge ensures it retains most of its capacity even during longer storage, making it ideal for seasonal use.

Operating modes and charging parameters

The battery is designed for both continuous standby backup and repeated discharging and charging (cyclic operation). For backup standby mode, such as in UPS systems, we recommend a float voltage in the range of 13.6–13.8V. For cyclic use, where the battery is regularly discharged, charge it with a voltage of 14.5–14.9V. To preserve battery life, the maximum initial charging current must not exceed 7.8A.

Temperature-dependent performance and self-discharge

Battery capacity changes depending on the ambient temperature. At 40°C, it reaches 102% of its rated capacity, while at 0°C it drops to 85%, and at -15°C to 62%. The battery features low self-discharge, allowing for longer storage. After three months, it retains approximately 91% of its capacity, 82% after six months, and still 64% after nine months at a storage temperature of 25°C.
