Sealed Lead Acid Battery XTREME 12V 12Ah model 82-216# for UPS and backup power

Sealed Lead Acid Battery XTREME 12V 12Ah model 82-216# is a valve-regulated, maintenance-free battery engineered for small to medium backup power applications. It provides a stable 12V output with 12Ah nominal capacity and is suitable for both float (standby) and cyclic charging regimes commonly used in UPS units, emergency lighting and alarm systems. The compact sealed design minimizes maintenance and allows safe installation in enclosed enclosures used by UPS and power backup equipment.

Advantages

The valve-regulated sealed construction prevents electrolyte leakage and reduces maintenance needs while delivering reliable voltage under load. Its nominal 12Ah capacity balances energy density and physical size for tight spaces. The battery supports float charging for continuous readiness as well as cyclic charging for repeated discharge/charge cycles, making it adaptable to different backup and standby system requirements. Designed for long shelf life and predictable performance, it is compatible with common UPS and alarm system charging profiles.

Suitable for

• Uninterruptible Power Supplies (UPS) for computers and networking equipment
• Emergency lighting systems and exit signs
• Intruder alarm and security systems
• Small-scale backup power for telecom or monitoring devices
• Portable power modules and replacement battery packs

Key specifications

• Nominal voltage: 12 V
• Nominal capacity: 12 Ah (at standard discharge rate)
• Battery type: Sealed lead acid (valve-regulated, maintenance-free)
• Charge modes supported: Float (standby) and cyclic charging
• Construction: Absorbent glass mat (AGM) or equivalent sealed design
• Recommended operating temperature range: typical for lead‑acid batteries (see device manual for specifics)

How to use

Install the battery in a well-ventilated, dry enclosure and connect according to polarity markings to the UPS or backup device. Use a compatible charger or UPS charger configured for sealed lead acid batteries and follow the manufacturer’s charge voltage and current recommendations for float and cyclic regimes. Avoid deep discharges where possible; recharge the battery promptly after discharge. Observe safe handling: do not short-circuit terminals, do not open the sealed case, and avoid exposure to high temperatures or direct flame.

Usage recommendations

For optimal lifetime and reliable backup performance, keep the battery on a proper float charge when in standby service, perform periodic load tests according to your UPS or system maintenance schedule, and replace batteries showing reduced capacity or excessive self-discharge. Store batteries in a cool, dry place and charge them before long-term storage.
