Sealed Lead Acid Battery XTREME 12V 7.5Ah (model 82-219#)

The XTREME sealed lead acid battery 12V 7.5Ah is a maintenance-free, valve-regulated rechargeable battery designed to deliver stable 12-volt DC power for backup and small equipment applications. With a 7.5 ampere-hour capacity, this battery provides reliable energy storage for short to moderate runtime needs. The valve-regulated, sealed construction reduces the need for maintenance and minimizes the risk of electrolyte leakage, allowing installation in a range of orientations and confined spaces.

Advantages

This battery offers a compact form factor and predictable discharge characteristics suitable for standby and cyclic use. Its sealed, valve-regulated design prevents spills and reduces maintenance compared with flooded lead acid batteries. The 12V nominal voltage and 7.5Ah capacity make it compatible with many UPS units, alarm panels, emergency lighting units, and portable devices that require a stable DC supply. Built for tolerance to common environmental conditions encountered in indoor installations, it supports reliable performance over repeated charge and discharge cycles when used within recommended parameters.

Suitable for

• Uninterruptible Power Supplies (UPS) for small servers and home electronics
• Intruder and fire alarm systems
• Emergency and exit lighting
• Portable power for measurement instruments and handheld devices
• Backup power for communication equipment and control panels

How to use

Install the battery in a compatible compartment or enclosure that provides adequate ventilation and protection from direct heat sources. Ensure correct polarity connection to the device or charger and secure terminals to prevent accidental short circuits. Charge the battery with a compatible 12V lead-acid battery charger or through the equipment’s built-in charging circuit, following the manufacturer’s recommended charge current and voltage limits. Observe standard safety practice when handling batteries: avoid shorting terminals, protect against moisture and extreme temperatures, and allow the battery to cool before recharging after heavy use.

Usage recommendations

For best service life, store and operate the battery at moderate ambient temperatures, perform regular charging if the battery is held in standby, and follow the device manufacturer’s guidelines for replacement intervals. Dispose of the battery through appropriate recycling channels for lead-acid batteries.
