Ideal for everyday devices

These 9V alkaline batteries suit smoke alarms, flashlights, lanterns and similar everyday electronics. The four-pack keeps spares on hand for household or professional use. Duralock Power Preserve technology helps the cells retain charge while stored. They arrive new and ready to install.

Capacity and headroom

Each cell delivers 9 volts of alkaline power for low-to-moderate drain devices. The pack provides four replacements so multiple units can be serviced at once. Runtime depends on the specific device and its current draw. High-drain applications will deplete the cells more quickly.

Upgrade considerations

The pack replaces individual 9V cells in existing equipment without modification. A jump from zinc-carbon or older alkaline cells brings longer shelf life thanks to the five-year storage guarantee. Buyers who need rechargeable 9V options or higher-capacity chemistries should look elsewhere.

Questions about this item

Will these 9V alkaline cells power the MN1604 smoke alarm I already own?

Yes — the pack is listed for smoke alarms, flashlights, lanterns and everyday electronic devices that take a 9V battery.

How can I verify the Duralock Power Preserve Technology is keeping the charge after I open the pack?

Each cell carries a 5-year storage guarantee; if a device shows low voltage before that period, the technology is not performing as specified.

Does the 4-pack include a charger or do I need to buy one separately?

No charger is included or required — these are single-use alkaline batteries, not rechargeable cells.
