Description

The Procell Constant AA is a 1.5V alkaline battery designed for low-drain devices that require consistent power output over extended periods. The LR6 cell chemistry provides reliable voltage across the discharge curve, making it suitable for clocks, remote controls, portable test instruments and similar devices that draw minimal current over months rather than hours.

Sold as a single battery rather than a multi-pack, this option suits offices, workshops and homes where occasional replacement is needed rather than bulk stocking. The Procell Constant range is built for professional environments where device interruption carries a cost, so the battery prioritises predictable lifespan over peak discharge rate. The industrial-grade construction includes leak resistance and stable performance across typical indoor temperature ranges.

The AA form factor measures 50.5mm length by 14.5mm diameter and weighs 23g, fitting standard AA battery compartments in thousands of consumer and professional devices. The alkaline chemistry operates at 1.5V nominal voltage and performs best in devices drawing 10-50mA continuous current, though it will also power higher-draw devices for shorter periods. Procell packaging is designed for bulk professional use rather than retail display, so the branding is minimal and the focus is on the cell specification.

Frequently Asked

What's the difference between Procell Constant and standard alkaline batteries?

Procell Constant cells are optimised for low-drain applications with predictable discharge characteristics, making them better suited to devices like clocks and remote controls. Standard alkaline batteries may be optimised for higher peak current at the expense of shelf life or consistent voltage. Procell cells are also packaged for professional bulk use rather than retail.

How long does a Procell AA last in a typical device?

Battery life depends entirely on device current draw. In a wall clock drawing 10-20mA, a Procell AA typically lasts 12-18 months. In a TV remote drawing 1-5mA intermittently, it may last several years. In a high-drain device like a digital camera or torch, expect significantly shorter runtime.

Can these batteries leak if left in a device?

All alkaline batteries can leak if left in a device beyond their useful life or if stored in high-temperature or high-humidity conditions. Procell cells include leak-resistant construction, but best practice is to remove batteries from devices that won't be used for extended periods.

Are Procell batteries rechargeable?

No. Procell Constant AA cells are single-use alkaline batteries and must not be recharged. Attempting to recharge alkaline batteries can cause leakage, rupture or fire.
