GFMJ-300 2V 300Ah GFMJ Gel VRLA Battery is structured as an engineering-grade product page for international B2B buyers, combining technical specifications, application logic, performance curves, FAQ and datasheet access.
GFMJ-300 belongs to the CHISEN Gel VRLA industrial standby battery platform. This page is designed for selection, comparison and inquiry by distributors, OEM buyers, system integrators and project engineers.
Application mapping helps buyers select the correct battery platform by industry and working condition rather than by model number only.
The following curve area standardizes how charging, discharging and storage behavior are explained across CHISEN product pages. Final curve values should be confirmed by the model-specific datasheet when available.
Shows typical charging voltage, charging current and capacity recovery behavior.
Helps engineers estimate voltage behavior under different discharge rates.
Supports storage planning and high-temperature market evaluation.
GFM is AGM VRLA; GFMJ is gel VRLA. GFMJ is often preferred where deeper cycling or higher temperature tolerance is required.
Yes. GFMJ gel VRLA batteries are suitable for telecom backup and industrial standby systems.
It is a sealed VRLA battery and normally requires no water maintenance.
