AA battery alternatives?
AA battery alternatives?
(OP)
Hello all,
I am a physician in the process of designing a new power handle for standard ophthalmoscopses (the instruments that are used to look at retinas). As I know little about batteries, I was hoping somebody in this forum might help me with some basic questions:
All current ohthalmoscopes use two AA batteries for their power supply. However, we are trying to design a very compact handle, and I was wondering if anybody had any suggestions as to how we could deliver the same power using a smaller battery (ies). I would be willing to trade lifespan of the battery, but the power output would have to be the same, or the light would be too dim.
For example, is there a way to use a single AA battery or even AAA battery (or two of these) to power the device? Or is such a think impossible?
Thanks so much

If you use LEDs for a light source, their power consumption could be lower, and smaller batteries mught have comparable life to your current system.

RE: AA battery alternatives?
Is the scope a throw-away? (A ridiculous wasteful trend that seems to be appearing in the medical industry.)
Are you trying to make the handle shorter in length or smaller in diameter?

Just bear in mind that these batteries will last less than 1/10 of the time that a AAA battery would last, in general.
