environment. Ni-MH batteries have greater energy density ratio, which means that digital devices can not add additional weight of the case, the use of nickel-metal hydride batteries can effectively prolong the working time. At the same time in the electrical properties of nickel-metal hydride batteries and nickel-cadmium batteries are also aspects of similar, in the practical applications can replace nickel-cadmium batteries, without the need of any transformation equipment. Another advantage is the nickel-metal hydride batteries: nickel cadmium batteries significantly reduces the problem of "memory effect", which makes nickel-metal hydride battery can be more convenient to use. Battery life is the use of a period of time, charge and discharge capacity decreased to 80% of the nominal capacity of the charge and discharge times before, is not or can not discharge the battery life is completely ineffective; self-discharge rate refers to the battery fully charged do not put the case for a long time the slow self-discharge phenomenon. Low self-discharge capacity decreased after that extended period of time less.

To go out shooting for the show or news interview, generally the use of portable video device, portable video equipment for use with batteries, can efficient, provide high quality work long hours to ensure continuous smooth filming the crucial link. The normal functioning of the battery with our TV, audio-visual workers in their daily work in the proper use and careful maintenance are closely related, the use and maintenance problem that deserves our attention.

1, in their daily work, should be familiar with their own type of battery, it has the basic characteristics and performance. This guide us in the correct use and maintenance is of great significance, for extending the battery life is also very important.

2, charging the room temperature is best controlled at between 10 -30 , the right temperature higher than 30 degrees is best to take measures to avoid overheating due to the deformation of the internal battery; room temperature below 5 degrees Celsius, the charge will cause lack of affect battery life.
