Description

The Duracell Procell Constant is a C size (LR14) 1.5V alkaline battery built for professional and commercial applications requiring reliable medium-drain power. Procell Constant is Duracell's industrial line, formulated for devices that draw steady current over extended periods rather than intermittent high-drain bursts — torches, portable radios, children's toys, emergency alarms and sensor equipment.

Sold as a single unit rather than multipacks, this format suits businesses managing inventory for device-specific replacements or users needing one spare cell for a particular application. The alkaline chemistry delivers stable voltage throughout the discharge curve, meaning devices maintain consistent brightness or volume until the battery nears depletion rather than gradually dimming. The C cell form factor measures 50mm height by 26.2mm diameter, fitting devices with LR14/C battery compartments.

Procell Constant batteries are designed for professional environments where device downtime costs time or revenue — hospitality remote controls, care home alarms, retail torches, facility management sensor equipment. The cells are date-coded for stock rotation and carry a shelf life of up to 7 years from manufacture when stored at normal indoor temperatures (20°C). Each cell weighs 70g, reflecting the alkaline paste and zinc anode construction inside the steel casing.

Frequently Asked

What devices use C size batteries?

C cells are used in medium-drain devices that need more capacity than AA or AAA cells can provide — torches, portable radios, children's battery-operated toys, alarm keypads, emergency lighting units and some sensor equipment. The larger cell body allows higher energy storage without moving to D cell dimensions.

What is the difference between Procell Constant and standard Duracell batteries?

Procell Constant is Duracell's industrial range, formulated for professional use where reliable medium-drain performance and stock management matter more than peak high-drain output. The cells are date-coded for inventory rotation and sold in formats suited to business purchasing. Consumer Duracell batteries prioritise marketing and retail packaging.

How long does a C size alkaline battery last?

Runtime depends entirely on the device's current draw. A torch drawing 200mA might run for 15-20 hours, while a low-drain alarm sensor drawing 10mA could last several months. Procell Constant is optimised for steady medium-drain applications rather than high-current bursts.

Can these be recharged?

No. Alkaline batteries are single-use and must not be recharged. Attempting to recharge alkaline cells can cause leakage, overheating or rupture. For rechargeable C cells, look for NiMH (nickel-metal hydride) versions instead.
