Lead‑acid AGM battery XTREME 12V 3.4Ah (model 82-214#)

Sealed lead-acid AGM battery XTREME 12V 3.4Ah is a maintenance-free, valve-regulated rechargeable battery designed for standby and portable power applications. With a nominal voltage of 12 volts and a capacity of 3.4 ampere-hours, this XTREME battery provides short-term power delivery and reliable backup for small electronics and safety systems. The absorbed glass mat (AGM) construction reduces electrolyte leakage risk and allows flexible mounting positions, while the sealed design eliminates the need for regular water addition or open-cell ventilation.

Advantages

The XTREME 12V 3.4Ah AGM battery offers stable voltage output and low self-discharge suitable for long-term standby use. Its valve-regulated design ensures safety under normal charging and discharging conditions, and the maintenance-free construction simplifies installation and operation. The compact dimensions and sealed case enable use in confined or portable enclosures without special ventilation, and the AGM plates provide good vibration resistance compared with conventional flooded lead-acid cells.

Suitable for

• Uninterruptible power supplies (UPS) for small electronics and network equipment
• Alarm and security systems, access control devices
• Emergency lighting and exit signs
• Portable testing equipment and small electric tools
• Backup power for routers, modems, and telecommunication devices

How to use

Install the battery in the correct polarity orientation into the device or enclosure, making sure terminals are properly connected and secured. Charge the battery with a compatible lead-acid/AGM charger following the device manufacturer's recommended charging profile and current limits. For standby systems, keep the battery connected to the charger or float charging circuit to maintain optimal charge level. Avoid deep discharges where possible; if deep discharge occurs, recharge promptly according to the recommended procedures.

Usage recommendations

Store and operate the battery in a cool, dry environment away from open flames and corrosion agents. Periodically check the charging system and terminal connections for corrosion or looseness. Replace the battery at the end of its service life or if capacity significantly declines. Use chargers and equipment designed for sealed lead-acid/AGM batteries to prevent overcharging and extend service life.
