Apologies up front for the log post, but trying to give all the pertinent info. I have been using a PMNN4547A Impres2 battery in a top display only APX7000 (H97TGD9PW1AN) and charging with an Impres1 charger (NNTN7079A). I would run it most of the day (just listening), and charge during the night. I didn’t charge every night, probably 3-4 times a week. It would do the reconditioning on its own occasionally and I’d let it go all the way to solid green. One day after about 5 months, I noticed that the battery display wasn’t showing full - and, sure enough, it would start chirping and showing low battery after about 6 hours - it had been going much longer. I tried to force recondition, but with the same results. I recently got a second APX7000 with a full display, so now I’m able to read some details on the battery. I also switched to using an Impres2 charger ((NNTN8845A). When fully charged (solid green light), the radio shows Charge 35%, Rem Cap ~3100. That gave me the idea to let the radio run even with the battery chirping to see what would happen. It chirped and showed Low Batt for about 2 hours - I noticed it wasn’t chirping any more and thought it was dead, but when I looked at it, it was showing almost full (more so that what it had been showing when fully charged). I stuck the battery in the full display APX and it was showing Charge 70%, Rem Cap 2100. So, I’ve tried several things: recharging at that point; force reconditioning at that point; letting it run down again (just to showing low) and doing both those - nothing seems to work to get the battery to show full charge % when the capacity is full. So I have two questions: 1) was it possible I did something to cause this? My main concern is that if so, I don’t do it to any other batteries; 2) is there any way to get the battery back “in sync”? Here are a couple of other pieces of information: I cannot swear that I did the initial calibration correctly - I confess that I still have moments of reading directions when all else fails. But, it did see several months of use with no problems and this issue happened suddenly. Also, I did follow some advice that I read on one of the forums about having the radio sitting in the charger while loading codeplugs - so I did - and I loaded a lot of codeplugs early on.
Thanks for reading, and I appreciate any advice.
