I am building a radio control remote for a camera requiring a 5Volt 13 m/a
supply

and using 4 x AAA

Are any smaller batteries available to keep the size and weight down

Any Help appreciated

Many Thanks

You could use button cells.

Ok, then use rechargeable button cells...
but seriously...
Lithium is the way to go for light. If you can make the system go on
4V, you may get by with one lithium cell.

If you've got a radio receiver, why not just steal power from that?

I bought 50 LR-44 button cells (alkalines) on Ebay for about $6
including shipping. They came packed in tear-off blister packs. These
are the ones used for laser pointers and LED flashlights. They will
handle 13 mA for a few hours. But they're only a dime apiece so you
just throw them away and put a few more in. Four of them will give you
about 6V, so you can put a 1N4002 rectifier diode in series with one
lead to drop about .8V to give about 5 or so volts.

With the lower the volts and m/a the longer life I am trying to compromise

between this and working range

Many thanks for your help
