Zinc carbon batteries suit low-drain devices that draw current intermittently or at low rates — torches used occasionally, wall clocks, AM\/FM portable radios, and remote controls for infrequent-use appliances.\u003c\/p\u003e\n\u003cp\u003eThe D cell format measures approximately 61mm tall by 34mm diameter, fitting standard D battery compartments in torches, lanterns, and portable audio equipment. Zinc carbon batteries discharge more gradually under low current draw than under continuous heavy load, so they perform best in devices that are switched on briefly or left running at low wattage for extended periods. For high-drain devices such as motorised toys or digital cameras, alkaline or lithium cells are more appropriate.\u003c\/p\u003e\n\u003cp\u003eEach cell in the pack weighs approximately 100g and stores less total energy than an equivalent alkaline D cell, but at a lower cost per unit. The Eveready Super Heavy Duty range spans AA, AAA, C, D, 9V and 6V lantern formats, all using the same zinc carbon chemistry. Shelf life is shorter than alkaline — typically 2-3 years from manufacture — so these batteries work best when bought for immediate or near-term use rather than long-term storage.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth (mm)\u003c\/td\u003e\n\u003ctd\u003e24\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd\u003e120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth (mm)\u003c\/td\u003e\n\u003ctd\u003e80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Range\u003c\/td\u003e\n\u003ctd\u003eEveready Super Zinc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell Size\u003c\/td\u003e\n\u003ctd\u003eD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell Composition\u003c\/td\u003e\n\u003ctd\u003eZinc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat devices are D size zinc carbon batteries suited to?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eZinc carbon D cells work best in low-drain devices: torches used occasionally, wall clocks, portable AM\/FM radios, and remote controls for appliances that are not used daily. For high-drain devices such as motorised toys, digital cameras or LED torches used frequently, alkaline or lithium D cells provide longer runtime and better value.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long do zinc carbon batteries last in storage?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eZinc carbon batteries have a shelf life of approximately 2-3 years from manufacture. They self-discharge more quickly than alkaline cells, so they are best bought for immediate or near-term use rather than stockpiling for long-term storage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan these batteries be recharged?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. Zinc carbon cells are single-use primary batteries and cannot be recharged.

Alkaline D cells provide longer runtime in high-drain devices and have a longer shelf life, making them better for devices used frequently or stored for extended periods. Zinc carbon suits low-drain, occasional-use applications where cost per cell matters more than total runtime.\u003c\/p\u003e","brand":"Eveready","offers":[{"title":"Default Title","offer_id":46075187003659,"sku":"S3974","price":1.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S3974_1_906efd59-6ed8-4fbb-a874-cc327bb172c4.jpg?v=1730317765","url":"https:\/\/niori.co.uk\/products\/eveready-d-size-super-heavy-duty-zinc-carbon-batteries-2-pack","provider":"Niori","version":"1.0","type":"link"}
