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 good FLOAT charger charges the battery at a constant current until the 'FLOAT' voltage. (13.8V or 27.6V) is reached, then it progressively reduces the current to maintain that voltage. This gets about 75% capacity back into the battery quickly but then takes a long time to. restore the other 25%.
