Description

The Procell Constant AAA LR03 is a 1.5V alkaline battery built for low-drain professional and consumer devices including remote controls, wireless keyboards, computer mice, clocks and compact torches. Procell Constant uses an alkaline zinc-manganese dioxide chemistry optimised for devices that draw steady, low-level current over extended periods rather than high-intensity bursts.

Designed for environments where predictable battery life matters, Procell Constant batteries deliver consistent voltage output across their discharge curve, reducing unexpected device shutdowns. The single-cell pack suits replacement needs in households, offices, hospitality settings and light industrial applications where individual batteries are replaced as needed rather than in bulk. The compact AAA form factor (10.5mm diameter, 44.5mm length) fits standard battery compartments in most handheld electronics.

Industrial-grade construction includes an anti-leak design that reduces the risk of electrolyte leakage damaging device internals, particularly in devices left idle for weeks or months between use. The matt black finish on the cell casing includes clear polarity markings and a tactile positive terminal for correct orientation during insertion. Procell batteries carry a shelf life of up to seven years from manufacture when stored at room temperature, making them suitable for stocking in maintenance cupboards or bulk drawers.

Frequently Asked

What devices are Procell Constant AAA batteries best suited for?

Procell Constant AAA cells are optimised for low-drain devices that draw steady, low-level current over long periods. This includes remote controls, wireless keyboards and mice, clocks, bathroom scales, small torches and similar electronics. They are not designed for high-drain devices like digital cameras or motorised toys, which benefit from Procell Intense chemistry instead.

What's the shelf life?

Procell AAA alkaline batteries carry a shelf life of up to seven years from manufacture when stored at room temperature (approximately 20°C) in their original packaging. Extreme heat or cold can reduce shelf life.

Are these batteries rechargeable?

No. Procell Constant AAA batteries are single-use alkaline cells and should not be placed in a battery charger. Attempting to recharge alkaline batteries can cause leakage or rupture.

How does Procell Constant differ from standard Duracell consumer batteries?

Procell Constant is Duracell's industrial line, optimised for professional and bulk-purchase use. The chemistry and performance are similar to consumer Duracell alkaline batteries, but Procell branding, packaging and pricing are tailored to trade, facilities management and bulk buyers rather than retail consumers.
