Batteries GPL-4D-L Lifeline AGM Deep Cycle Battery 12V 210Ah

The Batteries GPL-4D-L Lifeline AGM battery is a high-performance, military-specification deep cycle battery designed for demanding marine and RV applications. This 12-volt sealed AGM (Absorbed Glass Mat) battery is manufactured in the United States using aerospace-quality construction methods.

Key Features:

• 210 amp-hour capacity at 20-hour rate for extended runtime
• Military specification construction with aerospace-grade materials
• Sealed AGM design - completely maintenance-free, no water additions required
• Industry-leading 2% per month self-discharge rate at 77°F for exceptional shelf life
• Threaded female post terminals for secure, vibration-resistant connections
• Non-spillable design can be mounted in any position
• Excellent deep cycle performance with superior recharge efficiency
• Resistant to vibration, shock, and extreme temperatures

Lifeline AGM batteries utilize thick plates and high-density active material to deliver reliable power for trolling motors, house banks, inverter systems, and other deep cycle applications. The absorbed glass mat design immobilizes the electrolyte, eliminating stratification and sulfation while providing faster charging and longer service life compared to conventional flooded batteries.
