12-Pack 9V Alkaline Supply

This 12-pack of 9V alkaline batteries provides reliable single-use power for household, office and professional devices. Each cell delivers a steady 9 volts and is designed for high-drain applications such as smoke detectors and measurement tools. The leak-proof seal helps protect connected equipment from internal fluid loss.

500 mAh Capacity and 10-Year Storage

Rated at 500 mAh, these batteries comfortably run smoke alarms, carbon monoxide detectors, garage door openers, clocks, radios, toys and flashlights for extended periods. They store securely for up to 10 years in a cool, dry place without significant capacity loss. The single-use chemistry means they cannot be recharged once depleted.

Replaces Individual 9V Cells in Bulk

This pack replaces the need to buy single 9V batteries repeatedly, reducing replacement hassle for multi-device setups. The jump is worth it when you maintain several alarms, sensors or audio devices that demand fresh cells on a predictable schedule. Not suited for users who require rechargeable cells or higher-capacity chemistries.

What exactly comes in the box and is anything else required to start using them?

The package contains 12 x 9V alkaline batteries (model 6LR61); no charger, adapter or additional accessory is needed because they are single-use cells
