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.
Charging voltage is in the range of 1.4â1.6 V/cell. In general, a constant-voltage charging method cannot be used for automatic charging. When fast charging, it is advisable to charge the NiMH cells with a smart battery charger to avoid overcharging, which can damage cells. NiMH battery can have two to three times the capacity of an equivalent size NiCd, and its energy density can approach that of a lithium-ion battery.
