Learn more by watching our Energizer EN22 | Industrial 9V Batteries video.
The Energizer EN22 is a 9.0-volt alkaline battery designed for industrial applications and everyday portable power. The EN22 delivers consistent voltage for flashlights, clocks, calculators, laser levels, stud finders, smoke alarms, and other battery-powered hand tools. Energizer Industrial batteries are alkaline (zinc-manganese dioxide), non-rechargeable, and feature a miniature snap terminal.
On the job site, 9V batteries power many portable test and diagnostic tools — laser levels, stud finders, smoke alarms on rental properties, and mobile calculators. Contractors often order 9V batteries in bulk to keep stock on hand for emergency replacements or regular tool maintenance. The EN22 comes in a box of 12 units and fits the standard 9V slot on any device designed for alkaline snap-terminal batteries.
Licensed electricians and facilities managers specify Energizer Industrial batteries because of their track record on rental properties, commercial buildings, and high-drain applications. The miniature snap terminal eliminates the need to adapt or retrofit connectors, and the 5-year shelf life means batteries stay ready between jobs. No special storage or handling is required.
The Energizer EN22 is not suitable for rechargeable applications or low-drain consumer devices (clocks, remote controls, calculators) where a standard battery would be more economical. Alkaline cells cannot be safely recharged and are engineered for single-use discharge.

(EN22)
The EN22 is a standard 9V battery with a miniature snap terminal, the industry-standard connector for all modern smoke alarms. It fits any smoke alarm designed for 9V snap-terminal operation without adapters or modifications. Confirm your smoke alarm's battery slot accepts a 9V snap terminal before ordering.
Shelf life is 5 years when stored at room temperature (21°C). Runtime in a smoke alarm depends on the alarm's battery test interval — most battery-backed smoke alarms test the battery monthly and typically consume the battery over 1–2 years of active service, then the EN22 is replaced during annual safety inspections.
The EN22 is alkaline (non-rechargeable). Alkaline batteries cannot be safely recharged. After discharge, discard responsibly — most recycling programs accept alkaline batteries without special handling or hazardous-goods declaration required.
Yes. The EN22's 500mAh capacity and miniature snap terminal suit high-drain portable test equipment like multimeters, laser levels, and stud finders. Runtime will be longer than in low-drain devices (clocks, remote controls) because these tools draw substantial current per charge cycle.
Store in a cool, dry location away from direct sunlight and moisture. Keep the protective guard on the battery terminals to prevent accidental short-circuiting. Avoid storing in hot vehicles or damp areas. At 21°C, the EN22 holds 5 years of shelf life, so bulk ordering is economical for facilities with regular replacement cycles.
Sparky Direct stocks the EN22 in 12-pack boxes as the primary listing. Bulk quantities reduce per-unit cost and are ideal for facilities, rental properties, and contractors managing multiple alarms. Contact Sparky Direct customer service if you require a smaller quantity for a one-off purchase.
The EN22 contains no mercury or cadmium, so it does not require special disposal in most Australian states. Many recycling programs accept alkaline batteries in standard household recycling or at battery collection points. Check your local council's waste disposal guidelines for drop-off locations.
Energizer brands the EN22 "Industrial" because it is engineered for high-drain and continuous-use applications typical of commercial, industrial, and professional environments. Smoke alarms, laser levels, multimeters, and security systems are professional-grade applications. The EN22 is not optimised for low-drain consumer devices (children's toys, low-use remote controls).
The Energizer EN22 is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
