2xAA vs. 4xAAA Logic/Rational?

[GhostDoggy]

I have a small remote control that uses two (2) AA batteries. I have a larger remote that uses four (4) AAA batteries. I'm trying to understand the logic, if any is there to understand, what the larger remote needed a smaller battery form-factor than the smaller remote did with its larger battery form-factor. Both remotes run the batteries in series so its not a voltage-requirement thing. Both remotes are use for A-V gear.

Also, the cost for a AAA battery is substantial more compared to a AA battery, yet their respective manufacturing processes are identical, with the AAA battery using less material. Nice!

Someone didn't pay attention in school. If the batteries are in series, the voltage doubles!

Confirmed. Connecting the + of one to the - of another is called "series", as opposed to the + to the + and the - to the - which is "parallel". Series effectively doubles the voltage, in this case probably because the remote has backlit keys, or has a more powerful LED.

So, what is being said is that there is no easy, cheap way of taking a 3VDC and turning it into a 6VDC? Hmm, I would have thought that would have been trivial. Ok, so how about the cost of manufacturing AAA vs. AA? Less material, same manufacturing process, yet AAA>>AA in retail costs.

BTW, what school would I have had to been in to learn series vs. parallel voltage potential laws? Admittedly, I was a sixth-grade dropout. 🙁

The cheapest way to make 3VDC into 6VDC is to add two more batteries. Less manufacturing cost for them, more battery cost for you.

As for the rest of it, sounds like a personal problem.

a) not as trivial as adding more space for more batteries
b) the idea is that you'll get more life out of 4 AAAs than 2 AAs
