一.电池的型号：(在购买电池前应先根据使用要求确定电池的类型及型号。电池的型号通常是在电池的正面由字母和阿拉伯数字组成。锂电池的编号通常为CR####,BR####. 例如BR2032, 20表示电池直径为20mm，32表示电池厚度为3.2mm
二.松下BR系列电池为松下独家供应，适用温度区间广(-30度--80度)，电化学性能稳定，特别适用于在后备条件下的小电流放电
三.BR系列电池产地均为日本
四.避免新旧电池混用，不仅极易造成安全隐患，而且对使用寿命影响较大BR High Temperature Button Cell Model No.Nominal Voltage(V)Nominal Capacity (mAh)Pulse(mA)Continuous (mA)Low- Drain(μA)Diameter(mm)Height(mm)Approx.  Weight(g)BR12163.02550.03112.51.600.6BR12203.03550.03112.52.000.7BR12253.04850.03112.52.500.8BR16163.04880.03116.01.601.0BR16323.012080.03116.03.201.5BR20163.075100.03120.01.601.5BR20203.0100100.03220.02.002.0BR20323.0190100.03420.03.202.5BR23203.0110100.03223.02.002.5BR23253.0165100.03323.02.503.2BR23303.0255100.03523.03.003.2BR30323.0500100.031030.03.205.5BR1225A3.04850.03112.52.500.8BR1632A3.012080.03116.03.201.5BR2330A3.0255100.03223.03.003.2BR2450A3.0600100.03224.55.05.9BR2477A3.01000100.03524.57.78.0Note: BR battery operating temperature range from-40°C to 85°C;
