I bought a set of Uniden GMR2240-2CK walkie talkies for a song on Ebay, and at first everything looked perfect. But later one of the radios refused to transmit, and showed a low battery indicator, earlier than it should have. I switched the batteries between the radios, recharged both, and tested again. The shutdown happened again, but the good news is the problem followed the battery to the other radio. Well, the date code is 2211, so I think it's time.
I see that I can buy a set of two replacement EBL brand battery packs (BP40) on Ebay for under $8 delivered for the pair. I've always had good luck with generic batteries, but I know others haven't. Has anyone here had experience with these? Genuine Uniden replacements would be about $40.
And just to check my logic, it does make sense, doesn't it, that if the problem follows the battery, then the battery is the problem, not the radio? The thing that's curious is that if I wait a while after the shutdown, I can fire up the radio again, and it shows a full battery indicator, and the thing will run in listening mode for another hour or two. Maybe it's a heat related connection issue inside the battery pack. I further assume that at these prices for replacements, it makes no sense to try to replace the NiMH AAA cells in the pack, particularly since I don't know for sure that the problem isn't in the electronics inside the battery pack.
