Reliable Backup Power

The GD Lite DNMAX GD-645 battery is designed to store electrical energy and supply power when needed. It can serve as a backup power source for compatible equipment during electricity interruptions, helping supported devices continue operating for a limited period.

Its compact capacity makes it suitable for applications with relatively low power requirements. Actual backup duration depends on the connected device’s power consumption, battery condition, discharge rate, and operating environment.

Battery Capacity and Energy Storage

With a nominal voltage of 12V and a capacity of 4.0Ah, this battery has an approximate nominal energy rating of 48Wh (0.048kWh).

This rating represents the battery’s nominal stored energy. The amount of energy that can be used in practice may be lower depending on discharge conditions, battery age, temperature, and the requirements of the connected equipment.

For example, a device that consumes more power will generally use the stored energy faster than a low-power device. Check the equipment’s power requirements to estimate the expected backup duration.

Sealed Lead-Acid Battery Technology

Sealed lead-acid batteries are commonly used in standby power and backup applications. Their sealed construction is designed to reduce the need for routine electrolyte maintenance compared with traditional flooded lead-acid batteries.

The exact internal design of the GD-645 should be confirmed with the supplier, including whether it uses AGM or another sealed lead-acid configuration. Using the correct charging voltage and current is essential for battery performance and service life.
