The nominal voltage of alkaline manganese battery is 1.5V, and the highest voltage is1.65v. Compared with ordinary zinc-manganese battery, its discharge performance has the following characteristics: ① The internal resistance is small, and it can work continuously under heavy load while maintaining a high stable voltage; (2) The utilization rate 2) ②MnO2 _ 2 _ 2 is high, and its charge is about twice that of cardboard battery compared with its volume; ③ The self-discharge rate is low during storage, and it can still maintain 85% of the original charge after storage for 3 years, with long service life; ④ Good low temperature performance, which can output 25% of normal temperature charge at -20℃ and work at lower temperature under light load; ⑤ It can be used as a cheap rechargeable battery under specific design and strictly controlled use conditions. Doping titanium or other metal oxides can improve the charging performance of MnO22 _ 2. Specifications and uses The main specifications of cylindrical alkaline manganese batteries are shown in the table. The charge capacity of button alkaline manganese battery is about 55% of that of zinc-silver button battery of the same size. Commonly used models are LR4 1, LR43, LR44, LR54 and LR55. Its size and specification are the same as its corresponding zinc-silver button battery.
If there is no weight limit, electrical appliances using ordinary zinc-manganese batteries can generally be replaced with alkaline manganese batteries of the same size, which is especially suitable for occasions with continuous discharge of high current of more than 500mA (such as tape recorders, micro players, glare lamps, sprayers, toys, razors, etc.). ) and occasions requiring long-term storage. Button alkaline manganese battery is widely used in miniature radios, hearing AIDS, calculators, electronic lighters, music cards and so on because of its low price.
