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.

Questions about this item

What device do I need that takes a 9V lithium cell to use this battery?

Any device designed for a standard 9V battery — smoke alarms, wireless microphones, guitar pedals, medical monitors — will accept this lithium manganese dioxide cell.

Can I mix this lithium 9V with older alkaline 9V batteries in the same device?

No; mixing chemistries can cause leakage or reduced runtime, so replace all cells in a multi-battery device with fresh lithium units at the same time.

How can I confirm the battery is still good after years in storage?

The supplier rates shelf life at up to 10 years; a fresh cell should power the target device immediately and the leak-proof construction prevents corrosion damage.
