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.
To do a quick easy load test, hook up a volt meter to the battery observe the voltage should be around 12.7V if it's around 13 or so due to the car recently running turn on the headlights for about 5 seconds and that should take care of the surface charge you should be closer to 12.7V now.
