In addition, had the BC700 and BC900 both the same problem with the left outer battery slot, as was always turned off too early or displayed at Test and refresh too little capacity (same battery into one of the other shafts loaded / tested showed significantly higher capacity, other in the left slot like to significantly less).
This "series error", of which I have also heard and read elsewhere (sometimes even one of the other shafts was concerned) is also eliminated the BC1000.
The supplied battery adapter ... well. They are usable, who also not very functional.
And the batteries ... so the best thing you can say to those is that they are excellent to, to demonstrate the effect of the refresh mode.
Upon delivery, a far cry from the printed 2700mAh, it could the BC1000 at the first attempt after all ninety (90!) Mah at worst and 700mAh at "best" battery 1500mAh prop. Are left a few days and again refresh run yielded then after all 1900-2100mAh.
Refresh run of quality batteries (eg Varta Ready 2-1600 and use 2100mAh) hoisted the displayed capacity even at values slightly above the manufacturers imprint (1750 and 2200mAh)
