Carbon batteries should be used, because the quartz clock itself consumes very little power, a battery can be used for a long time, if it is alkaline for a long time leakage will harm the product. Today's batteries are required to be mercury-free and environmentally friendly, so don't worry.
Carbon battery belongs to the primary battery in the chemical power supply, is a disposable battery, also known as dry battery. Carbon batteries are not only suitable for flashlights, semiconductor radios, radio recorders, cameras, electronic clocks, toys, etc., but also for national defense, scientific research, telecommunications, navigation, aviation, medicine and other fields in the national economy.
Extended information:
characteristic
1, the full name of carbon battery should be carbon zinc battery (because it is generally positive carbon rod, negative electrode is zinc skin), also known as zinc-manganese battery, is the most common dry battery, it has the characteristics of low price and safe and reliable use, based on environmental considerations, because it still contains cadmium, so it must be recycled, so as not to cause damage to the earth environment.
2, alkaline battery is suitable for large discharge and long time use. The internal resistance of the battery is low, so the current generated is larger than that of the general zinc-manganese battery, the conduction is copper rod, and the shell is steel shell, which is safe and reliable. No recycling required. Based on his environmental protection, as well as the characteristics of large current, alkaline batteries are more.
3, the advantages of carbon batteries: carbon batteries are easy to use, cheap, optional types and prices are very many.
4, the disadvantages of carbon batteries: can not be recycled, one-time investment is low, but the cumulative cost of use is high. Causing damage to the earth's environment.
5, carbon battery use note: if the camera is not used for a long time, it is not appropriate to put the carbon battery in the machine, too long, the carbon battery will flow out of the inside of some corrosive liquid, these liquids if the flow into the camera, it is very easy to cause component damage.
considerations
1, check whether the electrical and battery contact parts are clean, wipe with a wet cloth if necessary, and load according to the correct polarity after drying;
2, do not mix old and new batteries, the same model but different types of batteries can not be mixed;
3, it is prohibited to heat, charge or other methods to regenerate the primary battery; Do not remove batteries
4, prohibit the battery short circuit, beware of infants and toddlers playing with the battery, especially to prevent infants and toddlers from swallowing the button battery.
5. The switch should be cut off after the use of electrical appliances, and the battery should be removed if not used for a long time.
