What Is the DAXIN 6-GFM-250 12V 250Ah AGM VRLA Battery?
The DAXIN 6-GFM-250 is a 12V 250Ah AGM VRLA battery designed for UPS systems, telecom equipment, emergency power, security systems and other standby-power applications.
It uses AGM separators and lead-calcium alloy plates in a sealed ABS enclosure, providing low self-discharge and practical maintenance-free operation for backup-power installations.
Battery quantity, series/parallel configuration, charging settings and required capacity should be selected according to the UPS DC bus voltage, connected load and required backup runtime.
What Is a 12V 250Ah AGM VRLA Battery?
A 12V 250Ah AGM VRLA battery is a sealed lead-acid battery with a nominal voltage of 12 volts and a rated capacity of 250 amp-hours.
AGM stands for Absorbent Glass Mat, while VRLA means Valve-Regulated Lead-Acid. This battery technology is widely used in UPS, telecom and standby-power systems because it provides sealed construction and low-maintenance operation.
How Long Can a 12V 250Ah Battery Power a UPS?
UPS backup time cannot be determined from the 12V 250Ah rating alone. Actual runtime depends on the connected load, number of batteries, series/parallel configuration, UPS DC bus voltage, inverter efficiency, discharge rate, battery condition and operating temperature.
For accurate battery sizing, provide DAXIN ENERGY with the UPS model, critical load in kW, DC battery voltage and required backup time.
How to Select a UPS Battery
Select the battery system according to the UPS DC bus voltage, connected load, required backup runtime, allowable discharge rate, charging current, installation space, operating temperature and expected service conditions.
For multi-battery systems, the required number of 12V batteries and the series/parallel arrangement must match the UPS battery voltage and runtime requirements.
Provide the UPS model, load in kW, required backup time and installation environment to DAXIN ENERGY for battery-system sizing.
