Planning a trip off-grid or spending weekends on the water? You need a robust battery solution that can handle continuous use, discharge, and recharging cycles without failing. That’s where Discover Dry Cell AGM / VRLA deep-cycle batteries shine.

What Is Discover Dry Cell AGM / VRLA?

“Dry Cell” is Discover’s name for a sealed VRLA (Valve-Regulated Lead-Acid) battery built with AGM (Absorbent Glass Mat) technology. These batteries are maintenance-free, non-spillable, and designed to operate reliably under deep discharge conditions. :contentReference[oaicite:0]{index=0}

They incorporate Discover’s Hydro-Polymer electrolyte separators, enhanced alloy plates, and carbon-boosted additives to support better cycling, partial state-of-charge tolerance, and durability over life. :contentReference[oaicite:1]{index=1}

Why They Work for Caravans, Boats & Leisure Use

• Deep-discharge tolerance: Designed to handle repeated discharges and recharges — ideal when your fridge, lights, or pumps run off the battery for long periods.
• Partial State-of-Charge (PSOC) resilience: Many leisure setups don’t fully charge every cycle. Discover Dry Cell handles PSOC duty better than typical flooded batteries. :contentReference[oaicite:2]{index=2}
• Strong cycle life: The Discover marine / deep-cycle line is rated for high cycles (e.g. many models > 700 cycles at 60% DoD) in the marine/standby spec. :contentReference[oaicite:3]{index=3}
• Maintenance-free & sealed: No topping up, no spilling — perfect for marine use where battery leaks are unacceptable. :contentReference[oaicite:4]{index=4}
• Temperature & vibration resistance: Robust casing and design that tolerates heat, motion, and vibration common in boats and mobile setups. :contentReference[oaicite:5]{index=5}

Representative Discover Models & Specs

Here are a few popular Discover Dry Cell models and their specs for reference:

• Discover EV24A-A 12V 85Ah — suitable for smaller caravans or moderate load usage (inverter, lights). :contentReference[oaicite:6]{index=6}
• Discover EV12A-A 12V 140Ah — higher capacity for longer stays or heavier power draw. :contentReference[oaicite:7]{index=7}
• Discover EV31A-A 12V 115Ah — strong balance between capacity and size for marine or RV set-ups. :contentReference[oaicite:8]{index=8}

Choosing the Right Battery for Your Setup

• Estimate your daily energy demand (lights, fridge, pump, charger) in **amp-hours** and size your battery bank accordingly.
• Design for 50–70 % Depth of Discharge (DoD) to preserve battery life — buy a battery with higher capacity than your bare minimum requirement.
• Check terminal type, dimensions, and mounting compatibility with your caravan or boat battery box.
• Use a suitable charger or solar controller that supports AGM / VRLA profiles for optimal performance.
• Consider multiple batteries in parallel for redundancy and longer runtimes.
