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.
Test the battery or batteries for a short or open cell. Connect the BLS and fully charge the battery or batteries. Once charged, turn off or disconnect the charger. Leave the BLS connected and let the battery or batteries sit for 20 hours (it is best to not let the voltage drop below 80% of charge) Then, charge the battery or batteries and repeat the previous step.
