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.
Best Answer: When a car or truck battery is fully charged, the voltage will be 13.8 volts. You will have to check it with a digital voltmeter. When an alternator is charging, depending on the level of charge of the battery, it will produce from 14 volts for a fully charged battery to 15 volts for a partially charged battery.
