ENERGIZER L522BP 1-Pack Lithium 9V Standard Battery

Single-Pack 9V Lithium Battery

This Energizer L522BP is a single 9V lithium cell built for essential electronic devices. It uses lithium manganese dioxide chemistry to deliver long-lasting power and a leak-proof design. The battery weighs less than alkaline equivalents and holds its charge in storage for up to 10 years. It operates reliably in temperatures from -40°F to 140°F.

Best for Low-Drain Essentials

The cell suits smoke detectors, medical monitors, security sensors and other critical low-drain gear that must run for years without attention. It is not for high-drain devices such as digital cameras or motorised toys that drain voltage quickly. Buyers who need rechargeable cells or multi-pack value bundles should look at other options.

Simple Drop-In Installation

Installation is a straightforward snap into any standard 9V compartment; no tools or polarity adapters are required. The only common mistake is inserting the battery with reversed terminals, which prevents the device from powering on. Because the chemistry is non-rechargeable, attempting to charge the cell will damage it and void the safety design.
