As a result of this charge the compaq laptop battery has a high bulk density and stable voltage, fast electron in the civilian apparatus has been widely used to form a variety of shape and size range of the battery. There are circular and processing of zinc mercury batteries have mercury zinc manganese dioxide battery system, code-named, respectively, for the MR and NR, subsequent figures represent the battery model.
Structure: the market for many zinc-mercury armada m700 battery button-shaped, consisting of basically the same as zinc silver button batteries, only to replace Ag O as HgO cathode material, cathode also add 5 ~ 15% graphite in order to reduce the resistance. In order to improve the battery voltage, in some products is also adding some manganese dioxide. As the zinc electrode (anode), is now the majority of the use of zinc amalgam mix to gel material used in place of the early band of zinc foil.
Performance and characteristics: MR and NR mercury zinc evo n400c battery nominal voltage is 1.35V, respectively, and 1.40V, respectively, the highest open-circuit voltage of 1.37V and 1.60V. Electric battery performance characteristics are: a long storage life. MR battery open circuit voltage change is extremely small, only 5 years decreased 0.01V, it can be used as sub-standard to use, stable discharge voltage. At its smooth under light-load phase of the whole discharge time up to 97% more than high energy density. Up to 400mWh/cm3.
Specifications and uses: mercury-zinc batteries commonly used model specifications in Table zinc mercury evo n410c battery commonly used model specifications.
Zinc-mercury batteries mainly used in auto-exposure cameras, hearing aids, medical equipment, circuit boards fixed bias voltage, and some military equipment. Because of large-scale use of evo n600c battery, arbitrarily discarded after use would seriously pollute the environment, and therefore the scope of their production and use are tend to narrow, some are being replaced by zinc-silver battery.
