Most geeks will applaud the video by Kipkay on the 9V battery hack to get 6 AAAA batteries. It got us curious, as we happened to have a couple of 9V rechargeable batteries lying around. Originally, these batteries were used in a cool device called Animal Away that helped us get rid of the problem of four-legged friends using our front yard as their personal area. We gave away the device, the charger, and a couple of batteries when we moved. For some reason, the hoarder in us held on to the two remaining batteries.
The hack is right on the money as far as rechargeable batteries are concerned. We tested the hack on a radio that came with our kid’s bicycle and also on their Leappad. They both use AAA batteries, NOT AAAA that you get from the hack. All one needs are aluminum foils and voila! The AAAA’s are “converted” into AAA’s.
To be practical, is the hack useful? For us, we found use for our neglected 9V rechargeable batteries, which were gathering dust at best. A 9V rechargeable goes for roughly $5 while AAA’s can be had for $1 and a child can point out that the economics don’t hold up. Add in the labor and you lose hand over fist. Also AAAA batteries are hard to come by and if you chance devices that function on that kind of batteries, the hack may have some value. Below are details of some devices that need AAAA batteries:
It is only natural to wonder what other hacks are possible with batteries. Below are a couple that hold promise:
- Dismantling a 12V battery that costs $2 apiece to retrieve 8 watch batteries that can go for upwards of $5 apiece.
- Dismantling the 6V lantern battery to retrieve 32 AA batteries.

can you tell my the brand of this 9v rechargable battery containing 6 aaaa,
I looked for some 9v rechargable batteries. some of them were 8.4V and some were 7.2V, I think some has different solutions beside using aaaa batteries because, 8.4v = 7 x 1.2V and only max 6 aaaa can fit in the 9v case,
I need rechargable aaaa
The 9v rechargeable used in the testing was a store-branded product (green color) bought from the onlybatteries.com site. Looks like they have replaced the packaging on those - now it is colored blue:

Regards,
thanks for your help,
but as I have said before; this battery is also 8.4V, they use 1.2V cells in these batteries which means 7 batteries (8.4V = 7 x 1.2V)
. In a 9V battary case max 6 aaaa battery can fit. when replacing the packaging may they also change the voltage or structure inside?
If you still keep your old battery`s label can you tell me the voltage of yours,
thanks a lot
Yes, my old 9v rechargeable battery packaging has the following written on one side:
NiMH Rechargeable Battery
9V 170mAh
It has 6 AAAA's in it.
Hope this helps.
