JCB Ultra Alkaline D Batteries (LR20) - 2 Pack

These are D size alkaline cells from JCB, supplied two to a pack. Each one gives the standard 1.5 volts and carries the codes LR20 and MN1300, the two references you are most likely to find printed inside a battery compartment or in an appliance manual. D is the largest of the common cylindrical household sizes, so there is no mistaking it for anything else once the old cell is in your hand: if the device is marked D, LR20 or MN1300, this is the cell it takes.

D cells earn their keep in things that are physically big and run for a long time between changes. Rubber torches and work lamps, camping lanterns, portable radios, floor standing clocks, doorbell chimes, some children's ride-on toys and a good many battery powered garage devices all take them. The reason is capacity: a cell this size holds far more energy than an AA of the same chemistry, so a device that would flatten small cells in a weekend can run for a long stretch on a pair of these. Alkaline chemistry suits that pattern of use, holding a steady voltage under moderate continuous draw rather than the short sharp bursts a camera flash asks for.

One listing is a pack of two cells. The minimum order is 10, sold in multiples of 10, so the smallest quantity that leaves us is 20 cells, which suits a maintenance cupboard, a school or a site store better than a one-off replacement. It is worth changing both cells in a device at the same time, and keeping chemistries together rather than mixing a fresh cell with a part used one. These sit alongside our wider range of JCB cells, which also runs to AA, AAA, 9V and coin sizes.

Is an LR20 the same thing as a D cell?

Yes. LR20 is the international code for an alkaline D cell and MN1300 is the industry code for the same size, so a device asking for any of the three takes this cell.

How many cells do I actually receive?

Each pack holds two cells. The minimum order is 10 packs in multiples of 10, so the smallest order that leaves us is 20 cells in total.

Can these be recharged?

No. Alkaline cells are single use and must not be put on a charger. Rechargeable D cells are a different chemistry and give 1.2 volts rather than 1.5 volts.

My torch takes three D cells, so what do I order?

Two packs give you four cells, which covers a three cell torch with one spare. Fit a full set of matching cells rather than topping up with an older one.

Is a shelf life printed for this pack?

The manufacturer does not state a shelf life figure for this pack, so we quote none. Store unused cells somewhere cool and dry, in their packaging, until you need them.
