Battery hacking – turn your 9V into 6 AAA cells


Clever emergency hack of a Duracell 9V battery pack to provide six AAA batteries. Not sure how safe, useful or cost effective this is, but it’s worth remembering. Maybe. Lots of disclaimers.

 You will notice that these internal cells are a bit smaller than a normal “AAA” battery. However, by bending the attached tab on the internal cell, you can get it to work in most any application requiring a triple A cell, at least as a temporary fix until the right battery can be located.

  • These are QuadA (AAAA) batteries inside the 9 volt. I used to do this to power a laser I had that only took AAAA batteries. I found out pretty quickly that AAAA batteries are expensive and hard to find. Note: If you are looking for Quadruple A replacements, use Energizer 9 volts. Duracells are a -tiny- bit smaller lengthwise, and don’t work.

  • Thanks for the info Matt. I have to confess I’d never heard of AAAA batteries before this.
