Vipow BAT0223 Gel Rechargeable Battery 12V/55Ah

Vipow BAT0223 gel battery serves as a power source for backup systems. With its gel electrolyte, it requires no topping up or other regular maintenance. The battery provides a voltage of 12V and a capacity of 55Ah to power connected devices. Its shock-resistant design lets you store it in any position, making installation easy. The battery life reaches up to 500 charging cycles.

Operating parameters and charging

Gel electrolyte ensures completely maintenance-free operation because it requires no topping up. The battery is designed for specific voltage ranges that optimise its lifespan and performance. For stand-by mode, we recommend maintaining a voltage of 13.6–13.8V at 25 °C. For cyclic use, the charging voltage should range between 14.5 and 14.9V. The maximum recommended initial current is less than 16.5A, which protects the battery from damage.

Battery capacity depending on the load

The stated battery capacity varies depending on the discharge rate. The nominal capacity of 55Ah applies to a 10-hour discharge at 25 °C. If the load is higher and the battery discharges faster, for example in one hour, its available capacity drops to 34.6Ah. Conversely, with a slower 20-hour discharge, it provides a capacity of up to 57Ah. These values help you accurately plan the backup time for your specific device and its power consumption.

Performance at different temperatures and self-discharge

Ambient temperature has a significant effect on battery performance. At an optimum temperature of 25 °C, the battery reaches 100% of its capacity. At higher temperatures, such as 40 °C, its capacity increases slightly to 102%. Conversely, performance drops in colder environments – at 0 °C it is 85% and in freezing temperatures of -15 °C, capacity drops to 62%. The battery also discharges spontaneously: it retains 91% capacity after three months of storage, 82% after six months and 64% after nine months.
