Sealed Lead-Acid Battery XTREME 12V 7Ah model 82-211#

Sealed Lead-Acid Battery XTREME 12V 7Ah model 82-211# is a valve-regulated, maintenance-free rechargeable battery providing a nominal voltage of 12 V and a capacity of 7 Ah. Designed for backup power and portable applications, this SLA battery is suitable for installations that require reliable energy storage in a compact, sealed package. The construction allows for upright or side mounting and delivers predictable performance for standby and cyclic use in environments where a sealed, spill-proof battery is required.

Advantages

The battery's valve-regulated sealed design eliminates the need for regular electrolyte maintenance and reduces risk of leakage. With a 12 V nominal output and 7 Ah capacity, it balances energy density and compact size for use in a range of small to medium power applications. The maintenance-free chemistry and durable casing support long shelf life and safe indoor installation. Because it is rechargeable, the battery can be repeatedly cycled for backup systems and portable devices.
