12V Gel Battery XTREME 4Ah EB1500278421# — Maintenance-Free AGM Technology

XTREME 12V Gel Battery 4Ah is a compact, maintenance-free sealed battery combining AGM and gel construction to provide reliable 12V power in small installations. Its design delivers leak-proof operation, vibration resistance and low self-discharge for standby and cyclic applications. The battery is intended for use where a compact, sealed 12V source is required, such as backup modules, alarm systems and portable electronic equipment.

Advantages

This maintenance-free battery integrates AGM separators with a gelled electrolyte to minimize electrolyte movement and prevent spills, enabling sealed operation in any orientation. Low self-discharge ensures long shelf life and reliable standby performance. The robust construction improves resistance to vibration and mechanical stress, while the compact 4Ah capacity balances energy density and size for space-limited installations.

Suitable for

• Alarm and security systems

How to use

Install the battery in a dry, well-ventilated enclosure with adequate access to terminals. Ensure correct polarity when connecting to devices or charging equipment. Use a charger suitable for sealed lead-acid/gel-type batteries and follow the charger manufacturer’s charging profile to avoid overcharging. For standby applications, keep the battery charged to recommended float voltage and perform periodic voltage checks; for cyclic use, follow recommended charge/discharge cycles for gel/AGM batteries to maximize lifespan.

Usage recommendations

Store and operate the battery within the temperature range specified by the device you install it in. Avoid deep discharge and prolonged storage in a discharged state; recharge after use or storage to maintain capacity. Dispose of the battery according to local regulations for lead-acid batteries and recycle where possible.
