Compared with traditional SLA batteries, LiFePO4 batteries offer longer cycle life, lower weight, higher energy efficiency, and minimal maintenance. The GLFB7 eliminates routine lead-acid battery tasks such as water refilling and acid-deposit cleaning, helping reduce maintenance time and long-term operating costs.
Yes. It is designed for compatible 12V SLA battery systems. Before installation, confirm voltage, dimensions, terminal type, current requirements, charging profile, and available mounting space.
The recommended charge current is 6A, while the maximum charge current is 30A. Use a LiFePO4-compatible charger with the specified charging voltage and profile.
The battery is rated for more than 2,000 cycles at 0.2C and 100% depth of discharge. Actual service life varies with temperature, depth of discharge, charging habits, and load conditions.
Yes. It is suitable for compatible 12V solar storage, UPS backup, security systems, and other low-voltage energy storage applications. Confirm that the solar controller or charger supports LiFePO4 batteries.
No routine watering or acid cleaning is needed. Periodically inspect cables, terminals, and charging equipment to maintain reliable performance.
The IP65 enclosure provides protection against dust and water jets. The battery must not be submerged.
