I just started experiencing this on one of my two HP1s - the one that spends more time out in the wild, so to speak (mostly in the car, but sometimes at work or with me in a "portable" setting), connected and disconnected from DC power somewhat frequently. The batteries get run down somewhat regularly, and get at least a partial charge often. Every now and then I'll bring it into the house and drain it, then run a full charge.
Tonight, after draining the batteries enough to get the low power warning a couple times over the past few days, and a couple of partial charges subsequent to that, I tried doing a proper charge from AC power tonight, with the scanner turned off. After about 45 minutes, I got the "Battery Charge Error - charging aborted" message. I removed the cable and re-attached it after a few moments, and it only lasted a couple minutes before delivering the same message.
I've had the scanner on for about 25 minutes now sans external power and it appears to have at least a partial charge - no complaints of low battery or anything. The batteries in it were Duracell rechargeables, 2450 mAh, which I use in a number of other scanners and other devices without problems. The scanner is set to 2300 mAh/14 hours (evidently it got reset some time over the past while as I did set it for 2450 when I put that set of batteries in it, months ago). The batteries are neither hot nor unevenly warm - in fact they all feel the same uniform temperature close to the ambient level in the room. I'll try exchanging for another set in one of my other scanners, but has anyone got any insight into what's happened? I see some infrequent, vague references to this error message both here and on the HP1 forums, but without any real indication of the reason behind it. Is it likely this batch of batteries has gone bad, or is something else going on?
One last thing - both this HP1 and my other one just had the recently-released 2.01 firmware applied, and the other scanner is chugging merrily along, charging its batteries (even though I keep it attached to AC power 99% of the time, I decided to give the batteries a charge).
