Ok, so I ordered a new tenergy charger and 4 new RCR123a batts because the charger that came with my Prodigy was a little messed up (bad prong)... arrived today.
SUPER fast shipping, thanks guys.
I toss in a set of my older batts, they charge totally fine, then I charge up 2 of the 4 new batts and I hear the charger making a high-pitched buzz or humming sound. It's faint, but you can hear it. I figure I'll let it go, but keep an eye on it.
Now the LED went from red to yellow. NEVER saw yellow before, only red and green.
Should I be concerned?
