Slight overcharge..Problem?
I purchased a supposedly new never used 206b from her on HF. I have read about the calibration mode. It still seems to charge cell number 2 to .005 over, 4.205v. I don't think that is an issue, is it?
Thanks

Likely not an issue.
If you want, reduce the target voltage from 4.20V to 4.19V. Then it will be at 4.195V. I was charging to 4.18V anyhow, and have gone to 4.15V. It should allow getting more cycles out of the packs, and you only lose about 5% of the capacity by charging to 4.15V vs 4.20V (I've tested it, as has Gregor99). Another question might be how you're certain it's actually 0.005V over. If you have measurement equipment that accurate, you could use it to also re-calibrate the charger. Potentially in addition to reducing the target charge voltage.

I have reduced it in calibration mode. I have other devices and I'm going by what the 3 are telling me. Close enough for me. If needed I will keep reducing until all 3 show a max of 4.2v on all batts. Thanks
