I've been searching for a couple days for a rechargeable 28L type
( 6V./ dog collar style) battery. The only type found is lithium, but
not rechargeable.
Since I use this often, the Lithium cells gets expensive, and I want to
conserve waste and cost.
Does anyone know if they even make this cell type in Ni-MH or
other rechargeable chemisty ??
Thanks

Don't know what a 28L is presumably a watch hearing aid if it goes on
a dog collar?

I have this old Radio Shaft clock that takes (and promptly eats) 9 V
"standby" batteries.

I found two sources of mini rechargeable batteries for it. All
Electronics has a surplus 2.4 V 15 mah packs 0.93" X 0.54" X 0.15"

Their part number is NMH-15 www.allelectronics.com $1.25 each pack
(two cells in shrink tube served with wires and a connector)

I wired three in series and use a 10K resistor to trickle charge them
from the internal 10 V supply. Fits the 9V compartment with room to
spare.

Electronic Goldmine has similar packs.
