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.
individual CELLS are connected together 'in series' to make batteries of either 12 volt (6 cells) or 24 volt (12 cells). Although a battery is called a '12 volt' battery, its voltage varies from about 12.6 volts down to. 10 volts when it is discharging and can rise to 15 or 16 volts during charging. It is very. important, however, to limit the maximum battery voltage during charging otherwise the. battery will be damaged. The battery voltage should not exceed 13.8 volts for long periods. and 14.4 volts for short periods (8 hours maximum).
