What Is The GPL-1400T AGM Battery?
The GPL-1400T AGM battery is a high-performance Absorbent Glass Mat (AGM) battery designed for deep-cycle applications requiring reliable power and durability. With a 12V system and 1400 cold cranking amps (CCA), it features spill-proof construction, vibration resistance, and maintenance-free operation, ideal for RVs, marine systems, and solar storage. Its advanced AGM technology ensures faster recharge rates and longer lifespan compared to traditional flooded lead-acid batteries.

What defines the GPL-1400T AGM battery’s technical specifications?
The GPL-1400T AGM battery operates at 12V with a 1400 CCA rating, delivering robust starting power. Its AGM design uses fiberglass mats to immobilize electrolyte, enabling 3–5x faster recharging than flooded batteries. Pro Tip: Pair it with smart chargers to prevent overcharging, which can degrade its 500+ cycle life at 50% depth of discharge.

This battery’s vibration-resistant construction suits off-grid solar setups and marine environments. Its 220Ah capacity (20-hour rate) supports sustained energy delivery for appliances. For example, a single GPL-1400T can power a 100W RV fridge for ~22 hours. Tables below compare key metrics against competitors. Always ensure terminal compatibility—its SAE posts may require adapters for marine systems. Why risk shorter runtime? AGM’s sealed design outperforms flooded types in partial-state-of-charge scenarios.
| Parameter | GPL-1400T | Standard AGM |
|---|---|---|
| CCA | 1400A | 1000A |
| Cycle Life | 500+ | 300 |
How does the GPL-1400T handle deep-cycle applications?
Optimized for deep discharges, the GPL-1400T tolerates 80% depth of discharge (DoD) without sulfation risks. Its thick plates (4.2mm) resist corrosion, critical for renewable energy storage. Pro Tip: Use temperature-compensated charging to extend lifespan—voltage drops 0.03V/°C below 25°C.
In solar installations, the battery’s low self-discharge rate (3% monthly) minimizes energy loss. A 48V system using four GPL-1400Ts stores ~10.5kWh, sufficient for medium homes. But what about charge rates? Its 25A max charge current reaches 80% capacity in 5 hours. Compared to lithium, AGM sacrifices energy density (70Wh/kg vs. 150Wh/kg) but wins in cold performance (-20°C operation).
| Feature | GPL-1400T | LiFePO4 |
|---|---|---|
| DoD | 80% | 100% |
| Temp Range | -20–60°C | -20–45°C |
