Some Micrococcus are pigmented bacteria; for example, M. luteus produces yellow colonies and M. roseus produces redish colonies. Micrococcus species are oxidase-positive, which can be used to distinguish them from other bacteria like most Staphylococcus species, which are generally oxidase-negative.
A fully charged â12 voltâ battery will be at about 12.6V The charger may well take it up to 14.4 or so while charging. About 12.2 volts is 50% and 11.8 is approaching dead. (these voltages at no load, the battery at rest). Anything under 11.0 may indicate a dead cell.
The charging voltage for a battery will also vary from 2.74 volts per cell (16.4 for a 12v battery) at -40c to 2.3 volts per cell (13.8 on a 12 volt battery) at 50c. Some charge controllers have this temperature correction built in.
