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.
Gordon B has it dead on. Each cell in the battery when fully charged produces 2.1 Volts. Multiply that by six, and a fully charged battery produces 12.6 volts. When the alternator is charging, depending on the state of charge for the battery, at approximately 1500 RPM, the voltage should be 14.5 to 14.9 Volts. Some systems and certain battery chemistries will show a little more (as much as 15.2 Volts) or a little less (as little as 14.3 Volts), but ideally, 14.5 to 14.8 is ideal.
