Rechargeable Gum Stick Batteries

[Ali]

I am just wondering if anyone out there has a source for cheap but reliable
Rechargeable "gum stick" batteries. I am trying to replace some old
batteries and the only source I could find are these:
www.amazon.com/dp/B0047ZW46C/. Not sure on quality of the generic green
batteries, especially since they are going to be in a computer on an ISA
card and not easily visible. TIA!
