Vipow BAT0271 Gel Battery 4V, 4.9Ah

The Vipow BAT0271 gel battery is a reliable power source with a voltage of 4V and a capacity of 4.9Ah. This lead-acid gel battery is designed for use in uninterruptible power supplies (UPS) and other devices requiring a stable power supply. Its construction ensures a lifespan of up to 500 charge cycles, making it an economical solution for long-term operation. The F1 type connector makes connection quick and easy.

Detailed capacity specification

The stated capacity of 4.9Ah is a reference value that varies depending on the discharge rate. For precise planning, the manufacturer provides specific values for different loads. With a slow 20-hour discharge, the capacity is 4.5Ah. As the load increases, this drops to 4.28Ah over ten hours, 3.78Ah over five hours, and 2.7Ah during an intensive one-hour discharge. This data lets you optimise the device's performance according to real operating conditions.

Performance depending on temperature

The ambient temperature has a direct impact on the battery's available capacity. The reference point is a temperature of 25°C, at which the battery provides 100% of its capacity. At higher temperatures of around 40°C, its performance increases slightly to 102%. Conversely, its performance decreases in colder environments. At a temperature of 0°C you can expect 85% capacity, while in frost at -15°C, the available energy drops to 62%. Taking these parameters into account is key for reliable operation in different environments.

Self-discharge and maintenance planning

Every battery gradually loses energy, even when not in use. This model has a predictable self-discharge rate, which makes planning storage and maintenance easier. At a storage temperature of 25°C, the battery retains 91% of its capacity after three months. After six months, the remaining energy drops to 82%, and after nine months of storage, it will still have 64% of its original capacity available. Regular checking and recharging will ensure it is ready for use.
