What Is an Expedition Deep Cycle DC27 Battery?
The Expedition Deep Cycle DC27 battery is a 12V, 92Ah Absorbent Glass Mat (AGM) deep cycle battery designed for reliable, maintenance-free off-grid power in RVs and similar applications. Its durable, spill-proof, and vibration-resistant design offers extended cycle life, fast recharging, and excellent performance in extreme temperatures.
What Are the Key Features of the Expedition Deep Cycle DC27 Battery?
The DC27 battery provides 12 volts and 92 amp-hours with spill-proof AGM technology. It features thick plates for longer cycle life, vibration resistance, and operates safely in extreme temperatures from -40°F to 140°F. Its compact size fits most RV compartments and supports deep cycling and fast recharge cycles.
How Does AGM Technology Improve the Performance of DC27 Batteries?
AGM technology uses fiberglass mats to immobilize electrolytes, making the battery spill-proof and reducing internal resistance. This design enables faster charging (up to 5x faster than flooded batteries), deeper discharges (up to 80% DoD), longer cycle life, and better resistance to sulfation, making it ideal for off-grid and solar-powered applications.
Why Is the Expedition DC27 Suitable for Off-Grid RV and Marine Use?
With a capacity sufficient for powering RV essentials like refrigerators and LED lights for extended hours, the DC27 deep cycle battery handles repetitive discharge cycles efficiently. Its sealed, maintenance-free design and vibration-resistant construction make it ideal for rugged off-grid environments and mobile applications.
What Maintenance Practices Help Extend the Life of the DC27 Battery?
Keep terminals clean and corrosion-free using baking soda solutions. Store at 50%-80% charge in cool, dry places and avoid deep discharges below 50%. Use smart float chargers maintaining 13.6-13.8V and perform equalization charges biannually to balance cell voltages and prolong battery life.
How Does Temperature Affect the Performance of the DC27 Battery?
The DC27 performs reliably in extreme temperatures, retaining 65% capacity at -22°F due to thickened plates, dense electrolytes, and glass mat separators. This resilience ensures dependable cold starts and continuous power delivery in harsh climates, outperforming many gel and flooded batteries.
