锂电池真的比碱性电池好吗？ 一只电池的实际输出量是多少？ 在特定的时间内，一只灯的输出量能有多大？ 经过多次讨论后，我们决定引入一个新的术语：能量箱。电池供电组的能量箱是其中所有电池输出量的总和。
2 x CR 123 x 1300 mAh x 3,0 Volt = 7,8 watt hours
4 x AA x 2800 mAh x 1,5 Volt = 16,8 watt hours
Note according to the German Battery Act “Used batteries and rechargeable batteries are hazardous waste and must not be disposed of along with unsorted municipal solid waste (domestic waste or residual waste). This is indicated by the symbol of the crossed-out refuse bin on batteries and rechargeable batteries or their packages. The chemical symbols you may find underneath the refuse bin have the following meaning: Hg is for mercury, Cd is for cadmium, Pb is for lead. Consumers are legally obligated to hand in flat batteries after use. We are of course affiliated to the German GRS (joint return system), so used and flat batteries and rechargeable batteries purchased from us can either be returned to us, to municipal collecting points (public waste disposal authorities), or to any shop selling batteries and rechargeable batteries - free of charge. In doing so, consumers fulfill their legal obligations and make a substantial contribution to environment protection.”
