Sealed Lead-Acid Battery BLOW 82-211# 7 Ah - Rechargeable UPS/Backup Battery

Sealed Lead-Acid Battery BLOW 82-211# 7 Ah is a valve-regulated, maintenance-free rechargeable battery designed for standby and backup power in low-voltage applications. Its 7 Ah rated capacity delivers reliable short-term energy for UPS systems, emergency backup units, alarm panels and similar devices that require a compact, service-free battery. The sealed construction prevents electrolyte leakage and allows installation in upright or horizontal positions within equipment enclosures that support SLA batteries.

Advantages

The battery offers a compact form factor with a 7 Ah capacity that balances run-time and size for small to medium standby systems. Valve regulation and maintenance-free design eliminate the need for regular electrolyte checks or refilling. The rechargeable SLA chemistry provides predictable discharge and recharge behavior suitable for cyclic and standby operation. Typical terminal layout and robust construction make it compatible with many UPS, alarm and backup configurations.

Suitable for

• Uninterruptible Power Supplies (UPS) for home or small-office equipment
• Emergency backup modules and power packs
• Security alarm panels and intrusion detection systems
• Access control units and small telecommunication devices
• Portable power applications requiring a sealed 7 Ah SLA battery

Key specifications

• Battery type: sealed lead-acid (valve-regulated, maintenance-free)
• Rated capacity: 7 Ah
• Nominal voltage: 12 V
• Chemistry: lead-acid rechargeable
• Typical terminal layout: standard SLA terminal configuration for compact backup batteries

How to use

Install the battery in accordance with the equipment manufacturer's instructions, observing correct polarity and secure terminal connections. Use a compatible charger or UPS charging circuit designed for sealed lead-acid chemistry and 12 V nominal voltage; follow recommended charge voltages and current limits from the system documentation. For initial commissioning, fully charge the battery before placing it into service. Replace the battery when run-time falls below acceptable levels or when the battery no longer accepts charge according to the host device indicators.

Usage recommendations

Store and operate the battery within the temperature range specified by the equipment or system integrator; avoid extreme heat or freezing conditions. Avoid deep discharges whenever possible to extend cycle life and follow periodic maintenance checks of the host device (voltage, charger function, terminal cleanliness). Recycle the battery according to local regulations for lead-acid batteries.
