Uniross Active Heavy Duty Zinc batteries deliver consistent, dependable 1.5V power for the everyday devices that keep your home running. Designed for low to mid-drain applications, the Active range is the smart, cost-effective choice when you need reliable performance without paying for alkaline capacity you don’t need.

Why choose heavy duty over alkaline?

Alkaline batteries offer higher energy density and longer runtime — but that performance comes at a cost. For low-drain devices that draw a small, steady current over weeks and months, a heavy duty zinc battery delivers everything you need at a lower price per battery.

The Uniross Active range is mercury and cadmium free, making it safe to use at home and easy to dispose of responsibly through standard battery recycling.

Can I store heavy duty batteries long term?

Yes. Uniross Active Heavy Duty batteries have a 3-year shelf life, so buying a box of 40 is a practical way to keep a ready supply at home without worrying about batteries going flat in storage.

What size devices do AA and AAA heavy duty batteries fit?

AA (R6) batteries fit larger everyday devices — torches, radios, toys, and remote controls. AAA (R03) batteries are the slim format used in TV remotes, wall clocks, penlights, and compact wireless devices.
