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.
Battery voltage readings are as follows: 1  12.66 volts = 100% charged. 2  12.45 volts = 75% charged. 3  12.24 volts = 50% charged. 4  12.06 volts = 25% charged. 5  11.89 volts = 0% charged.
