At work, we have quite a few portable radios, powered by Ni-MH batteries. They charge them any old way, so the batteries fail quickly. Lithium batteries were ordered as replacements. If you're interested, read on after the break.

I have an ESR meter built using a circuit designed by GO, a fellow member of the pro-radio forum. I’m sure some of you use this meter too. I use it all the time, but when it runs on a 9V battery with the display backlight on, it drains batteries pretty quickly, so I decided to order a pair of rechargeable batteries for it. Details after the jump.
