Eveready C Size Super Zinc Heavy Duty Batteries (2 Pack)

The Eveready Super Heavy Duty C size battery is a 1.5V zinc carbon cell designed for low-drain devices where long shelf life and cost efficiency matter more than peak performance. Each 26mm diameter, 50mm tall cell delivers steady power to torches, wall clocks, radios, and remote controls that draw modest current over extended periods.

Sold as a 2-pack blister card, these batteries suit households, offices, and workshops that stock replacements for everyday devices. Zinc carbon chemistry provides a lower upfront cost than alkaline equivalents while maintaining adequate performance in devices that consume less than 50mA continuously. The cells are not rechargeable and should be disposed of according to local battery recycling guidelines once depleted.

Eveready manufactures the Super Heavy Duty range in C, D, AA, AAA and 9V formats, all sharing the same zinc carbon construction. The C size specifically fits mid-sized torches, larger portable radios, and certain battery-powered toys. The 0.1kg pack weight and compact blister packaging make these batteries straightforward to stock in a kitchen drawer or toolbox for when a device runs flat.

Carbon zinc cells perform best at room temperature and in devices used intermittently rather than continuously. For high-drain devices like digital cameras, motorised toys or LED torches drawing over 100mA, alkaline or lithium batteries would deliver better runtime. For low-drain applications where the device sits idle most of the time — a hallway clock, a spare torch, a bathroom radio — these zinc carbon cells provide adequate power at a fraction of the cost.

What devices are zinc carbon C batteries suited for?

Zinc carbon C cells work best in low-drain devices that draw less than 50mA continuously, such as wall clocks, basic torches, portable radios, and remote controls. For high-drain devices like motorised toys or high-output LED torches, alkaline batteries deliver better runtime.

What's the difference between zinc carbon and alkaline batteries?

Zinc carbon batteries cost less upfront but deliver lower total capacity and shorter runtime under heavy loads compared to alkaline batteries. Alkaline cells maintain voltage better under continuous drain and suit high-current devices. Zinc carbon suits intermittent, low-drain use where cost matters more than peak performance.

Are these batteries rechargeable?

No. Eveready Super Heavy Duty zinc carbon batteries are single-use cells and must not be recharged. Attempting to recharge a non-rechargeable battery can cause leakage, rupture or fire. Dispose of depleted cells according to local battery recycling guidelines.

How long do zinc carbon batteries last in storage?

Zinc carbon cells typically retain charge for 2-3 years when stored at room temperature in their original packaging. Store batteries in a cool, dry place away from direct heat and humidity to maximise shelf life.
