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.
Diagnosing low charging voltage. While you are ridding your motorcycle, the charging system provides electrical power to run electrical components and accessories. It also recharges the battery. Most of the electrical components will operate satisfactorily with a voltage between 12 and 15.8 volts DC. The battery is a little pickier about its charging voltage. Below 13.8 the battery will not fully charge. If the voltage is to high the battery will charge too quickly and may over charge. Either way high or low charging voltage can lead to battery problems. In order to get maximum battery life proper charging voltage must be maintained. Last month I talked about what to do if your battery is not staying charged. One of the tests was to check the charging voltage at the battery.
