Gel deep cycle battery 12V 220Ah — BAT412201104 by Deep Cycle Battery

The 12V 220Ah gel deep cycle battery BAT412201104 is a sealed, maintenance-free energy storage unit engineered for repeated deep discharges and prolonged service life. Using a gel electrolyte, the battery reduces water loss and self-discharge while offering stable performance under cyclic load. Its robust construction increases resistance to vibration and leakage, making it suitable for stationary and mobile installations that require reliable, long-duration power delivery.

Advantages

The gel construction delivers consistent capacity over many cycles with low maintenance requirements and minimal topping-up needs. Sealed design eliminates electrolyte spills and simplifies installation in confined or tilted positions. Low self-discharge and enhanced vibration resistance contribute to dependable operation in solar, backup and mobile power applications. The battery's design prioritizes safe cycling and longevity in repeated deep-discharge scenarios.

Suitable for

• Solar photovoltaic systems and charge controller storage
• Off-grid power for cabins, remote sites and recreational vehicles
• Uninterruptible power supply (UPS) for critical loads
• Marine and caravan electrical systems

Key specifications

• Nominal voltage: 12 V
• Nominal capacity: 220 Ah (C20)
• Electrolyte type: immobilized gel
• Design: sealed, maintenance-free
• Recommended operating temperature range: consult manufacturer data for optimal life (typical gel battery ranges apply)
• Mounting: can be mounted in upright and some tilted positions as allowed for gel batteries

How to use

Install the battery in a dry, well-ventilated location away from direct heat sources and corrosive substances. Use appropriate cable cross-sections and secure terminal connections to minimize voltage drop. Charge the battery with a compatible charger or charge regulator configured for gel-type batteries and the correct charging profile for 12 V lead-acid gel chemistry. Avoid deep discharges below recommended depth of discharge limits to extend cycle life, and restore charge as soon as practical after heavy use.

Usage recommendations

For best long-term performance, operate the battery within recommended temperature ranges, use a dedicated gel battery charging algorithm (constant voltage with appropriate float voltage), and schedule regular voltage checks. In solar or off-grid systems, pair the battery with a solar charge controller that supports gel battery settings to optimize cycle life and capacity retention.
