Eveready Super Heavy Duty D Batteries (R20) - 2 Pack

Two D size cells, supplied together on one retail card. D is the largest of the everyday cylindrical sizes, and like every cell in that family it gives 1.5 volts. The pack names the chemistry as carbon zinc, the traditional dry cell make-up sold under the Super Heavy Duty name. Carbon zinc suits equipment that draws a small, steady current over a long stretch of time rather than a heavy one in short bursts, and it is the economical way to keep that sort of kit running.

D cells are what the big household items still run on: rubber-bodied torches, camping and emergency lanterns, mantel and wall clocks, portable radios, doorbell chimes and the transformers behind them. Check the old cell before you order, because D is easy to confuse with the shorter C size; a D will not sit in a C holder and the spring will not close the circuit if you try. For anything that pulls hard and continuously, such as a motorised toy or a high-output lamp, our Eveready Gold D cells are the alkaline option and will run longer. For the rest, these are the sensible everyday choice.

One unit of this listing is the single card holding two cells, so a customer buying one gets two D batteries. It is a trade line, and the minimum order is 24 cards, bought in multiples of 24, which works out at 48 cells: worth knowing if you are stocking a shop, a village hall or a maintenance store rather than a kitchen drawer. Eveready does not print a shelf life figure on this pack. The same Super Heavy Duty range runs through AA, AAA and C sizes on our shelves, so one order can cover most of what a torch drawer needs.

Will these fit a device that asks for R20 or a D cell?

Yes. R20 is the standard code for a D size zinc carbon cell, so anything specifying R20 or simply a D battery takes these.

How many batteries do I actually receive?

One unit of this listing is a single card carrying two D cells. The minimum order of 24 cards therefore brings you 48 cells in total.

What is the difference between these and the Eveready Gold D cells?

These are carbon zinc and best suited to low, steady drain. The Gold D is an alkaline cell and will last longer in demanding equipment such as motorised toys.

Can these be recharged?

No. Carbon zinc cells are single use and are not designed to be put on a charger; for repeat charging you need a rechargeable D cell instead.

Are D and C cells interchangeable?

No. A D cell is both taller and wider than a C, so it will not fit a C compartment, and a C will not bridge a D holder.

What voltage does each cell give?

Each cell gives 1.5 volts, so a torch taking two in series runs at 3 volts and one taking four runs at 6 volts.
