Energy tank


Energy tank

Are lithium batteries really better than alkaline batteries? What output does a battery actually have? What output can a lamp have over a given period of time? After many discussions, we have decided to introduce a new term to the world of electric pocket lamps; the term energy tank. The energy tank of a battery-powered device is given by the output of all batteries in the device.

Example: Comparison the Batterie tank of a Surefire

Surefire E2L:
2x 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 in accordance with German battery legislation

Batteries do not belong in household waste!
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.”
