Summary

Description
English: Collage of images showing the dissection of a 9V (PP3) battery to reveal the 6 AAAA-like cells inside.

AAAA batteries are sometimes used in small devices like laser pointers and some remote controls. They are quite expensive and it is often cheaper to buy a well known 9V brand and take it apart to get to the cells inside. These cells are in fact LR61 which are about 3 mm shorter than AAAA (LR8D425) cells. However they are the same voltage and can be used in place of proper AAAAs and should function just as well. Although care should be taken with the difference in length and the lack of polarity markings on the cells themselves.

The red battery shown in the final image is a AAAA size, to show the minute difference in sizes.
