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.
A measurement of 12.6 V indicates a battery with a 100% charge. In-between measurements indicate a charge of less than 100%. A battery with a slightly higher voltage measurement (3% to 5%) is much better than a battery with a lower measurement. A dc voltage variation below the normal rated voltage indicates a problem.
