Energizer Industrial AAA LR03 Alkaline Batteries - 10 Pack

The Energizer Industrial AAA LR03 is a 1.5V alkaline battery designed for professional and high-drain consumer applications. This 10-pack contains individually sealed cells rated LR03 under IEC designation or AM4 under ANSI classification. The alkaline zinc-manganese dioxide chemistry provides higher capacity than standard zinc-carbon cells of the same size.

Designed for wireless keyboards, mice, remote controls, digital thermometers, handheld scanners, portable torches and medical devices requiring AAA power, the Industrial range sits between consumer-grade Energizer Max and the lithium Ultimate range in the manufacturer's hierarchy. The cells deliver consistent 1.5V output across discharge and maintain shelf life of 5-7 years when stored at room temperature.

Each cell measures 44.5mm in length and 10.5mm in diameter, fitting standard AAA compartments in both spring-contact and clip-contact battery holders. The leak-resistant construction uses a nickel-plated steel jacket with a recessed positive terminal and a flat negative terminal, reducing the risk of reverse-polarity insertion damage in devices with clear compartment markings. The 10-pack format suits bulk purchasing for offices, workshops and facilities management where multiple devices require regular battery replacement cycles.

How do Energizer Industrial batteries differ from Energizer Max?

Energizer Industrial batteries are designed for bulk purchasing in professional and commercial settings, with packaging optimised for inventory management rather than retail display. The core alkaline chemistry is similar to the Max range, but Industrial cells are typically sold in larger multi-packs and carry longer shelf-life ratings for stockroom storage. Performance in typical devices is comparable.

What shelf life do these batteries have?

Alkaline AAA batteries in the Energizer Industrial range maintain approximately 80% of their original capacity after 5-7 years of storage at 20-25°C. Store in a cool, dry location away from direct heat sources and metal objects that could short-circuit the terminals.

Are these batteries rechargeable?

No. These are single-use alkaline cells and must not be placed in a battery charger. Attempting to recharge alkaline batteries can cause leakage, overheating or rupture. Use Energizer rechargeable NiMH AAA cells if rechargeable power is required.

What devices are these suitable for?

AAA alkaline batteries suit medium-drain devices including wireless keyboards and mice, TV and audio remotes, wall clocks, digital thermometers, handheld barcode scanners, portable LED torches, bathroom scales and children's toys. Very high-drain devices such as digital cameras perform better with lithium or NiMH rechargeable cells.
