Many people have been stumped by the skinny little quadruple A (AAAA, Four A) batteries found in the N-Trig Digitizer Pens that come with the Motion Computing CL900, Fujitsu Q550, HTC Flyer and a number of other Lenovo, Dell and HP tablet PCs.

You might have wondered where on earth you get them from! They are a little bit obscure and hard to find.

Well you can stop hunting because we now have Energizer AAAA packs in stock and for sale in our online shop as a two pack or a dozen.
