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.
For LA batteries that are used in standby applications and are always being charged, the voltage is much closer to 13.2 volts, 2.2 volts/cell. For usage in RV's the charge time can vary considerably, from over night to a month or more. What voltage should our RV batteries be charged at. There are many factors, all with a specific answer which can get complex depending upon how many factors you take into consideration.
