My favorite part of the QC 25s is the top of the band, which is wrapped in a soft-touch black canvas cloth with squeezably soft, jet-black faux suede. The lower part of the headphones, including the outer earcups, is made of matte plastic. The earcups are gray and feature a ridged chrome Bose logo.y favorite part of the QC 25s is the top of the band, which is wrapped in a soft-touch black canvas cloth with squeezably soft, jet-black faux suede.

In an application like that, they could expect to see an OPTIMA battery last up to four years. However, in a more moderate climate, like San Diego, if someone might see four years out of a flooded battery, they could see up to eight out of an OPTIMA. How the batteries are used also impacts performance and lifespan.
The length of time that the watch battery lasts will depend on the type of watch and its functions. For example, if the watch can tell the time, date, act as a stop watch, and other functions, the battery will not last as long as a watch that just keeps the time. However, most watch batteries will last around 4 years.
