Description
A D cell is the largest of the common cylindrical battery sizes, and this pack holds two of them. Each one is a 1.5V alkaline cell carrying the codes LR20 and Mono, which are the markings you are most likely to find stamped inside a battery compartment or printed in an appliance manual. Both cells sit on a single blister card and stay sealed until you need them, and the front of the pack is marked Long lasting power.
D cells are chosen where a device needs to run for a long stretch rather than where it needs to be small: large rubber torches, camping and emergency lanterns, mains free radios, loud wall clocks, doorbell chimes and bigger children's toys. A D cell holds considerably more charge than an AA of the same chemistry and voltage, which is why manufacturers specify it for steady drain and for equipment that sits in a cupboard, a shed or a car boot between uses. Check the markings in the compartment before you order, because D and C are easy to confuse by name alone; a C cell is noticeably shorter and narrower.
Alkaline cells of this type are single use and must never be put on a charger; if you want cells you can top up again, a rechargeable NiMH D cell is a different product with a 1.2V nominal output. Replace every cell in a device at the same time rather than mixing a fresh one with a part used one, and take spent cells to a battery recycling point instead of the household bin. This listing is the two cell pack supplied without the inner box, and the minimum order is 12 packs in multiples of 12, which works out at 24 cells. The manufacturer does not print a shelf life figure on the pack.

Frequently Asked
Is a D cell the same as an LR20 or a Mono cell?
Yes. LR20 is the international code for an alkaline D cell and Mono is the German name for the same size, so all three describe the cells in this pack.
How many cells do I receive, and what is the minimum order?
One pack holds two D cells. The minimum order is 12 packs, sold in multiples of 12, so a first order brings 24 cells in total.
Can these be recharged?
No. Alkaline cells are single use and must never go on a charger. Rechargeable D cells are a separate NiMH product with a lower 1.2V nominal output.
Will they work in equipment supplied with zinc carbon R20 cells?
Yes. Both are 1.5V and physically identical in size, and alkaline cells generally hold more charge than zinc carbon of the same size under the same load.
Does the pack give a shelf life or an expiry date?
The manufacturer does not print a shelf life figure on the pack. The cells themselves carry a best before marking, so check that before fitting them.
