We were at the local Ollie’s store today and I saw something new. They were little plastic tubes that adapt AAA cells for use in devices that use AA cells. Just insert a AAA cell, the plastic tubes have metal terminals on each end. $3.39 for a package of eight. For some reason, I always have lots of AAA cells but keep few if any AA cells. Recognizing that there is much less power capacity in AAA cells, I think it is a good idea to have the little tube adapters in reserve just to simplify logistics and for emergencies.

I suppose if the goal is to use up the AAA batteries you have in stock and not let them waste away, it isn't a bad idea. For purposeful purchase of AAA instead of using the AA size, I see no percentages in that. As you stated the AAA will never last as long as the AA. That said, better used for half the time then to let them rot away unused.

Years ago I converted something that required 8 AA batteries to use D batteries instead. The devise lasted 10-12 times longer! This was for a video camera hidden in a Lionel Electric Train locomotive. Since the loco was not able to hold the D batteries, I ran a wire to the battery cradle in a box car behind the locomotive. Worked like a charm!
 
Battery converters have existed for a while, they are popular with those who use high-quality rechargeables such as Eneloop or Ladda. They are a great way to flexibly power many devices using different sizes with rechargeables

For what it’s worth, a AAA cell has about 1/3 the energy storage of a AA.

For the pedants, most of the disposable charged things we use are CELLS. A 9-volt is a BATTERY made up of six 1.5v cells. ;)
 
These are Duracell AAA bought at Home Depot. Batteries are at full charge but leak, Not the first time it happened. Will send pictures to Duracell.
I use rechargeable batteries now.
Have only had this happen with AAAs.

A great idea to have a few around ... especially in an Emergency ... we have Hurricane Season .
I have devices that take one or the other and usually run out of the one I need ...
Adapter could be a rescue !
Thanks for posting ,

That's why I only buy Energizer batteries. Much better than Duracell.
 
Looks like the DuraLeaks earned their name again.

An inexpensive, very high quality rechargeable cell is from IKEA - LADDA brand. If you use AA or AAA regularly, they’re worth a look. Also capable of much higher current than alkaline cells.
