Description
This is a two-cell pack of JCB AAAA alkaline batteries, the slim 1.5V size the pack also marks as E96. AAAA is one of the specialist formats rather than a household staple: it is noticeably narrower than an AAA and a little shorter, so the two are not interchangeable and a device asking for AAAA will only take AAAA. The cells are alkaline, the standard single-use chemistry for steady drain at ordinary room temperature, and each one gives the 1.5V printed on the pack.
The AAAA size turns up in equipment built around a pen-sized body: active stylus pens for touchscreen laptops and tablets, slim laser pointers, penlight torches, small medical readers and some compact measuring tools. If you are replacing cells, the quickest check is the old battery itself, because the size is almost always printed along the barrel next to the voltage. It is worth keeping a pack in a desk drawer or a tool bag rather than trying to buy one in a hurry, since AAAA is rarely stocked beside the AA and AAA cells on a shop shelf.
One unit is a blister card holding two cells, and the minimum order is 10 units, so that is 10 cards and 20 cells in total. That quantity suits an office, a school IT store or a workshop keeping stylus pens and pointers in service. The card prints no shelf life figure, so we quote none; store the cells dry and at normal room temperature, and leave spares in their card until they are wanted so the contacts cannot bridge against loose metal. The pack also carries the usual warning to keep batteries away from children. These sit alongside our wider range of JCB batteries, which covers AA, AAA, C, D and 9V as well as lithium coin cells.

Frequently Asked
Can I fit an AAA instead of an AAAA?
No. An AAAA cell is slimmer and shorter than an AAA, so an AAA will not seat in the holder and should not be forced.
How many cells do I actually receive?
Each card holds two 1.5V cells. The minimum order is 10 cards, which comes to 20 cells in total on one order.
What does the E96 marking mean?
E96 is another code for the same AAAA cell, printed on both the card and the battery barrel, so either marking on your device is a match.
Can these be recharged?
No. These are alkaline cells, which are single-use, so fit fresh ones when the device slows and recycle the spent pair.
What voltage does each cell give?
Each cell is rated 1.5V, as printed on the pack, which is the same nominal voltage as an AA, AAA, C or D alkaline cell.
Does the manufacturer state a shelf life?
No shelf life figure is printed on the retail card and none is given in the specification, so we do not quote one here.
