Auditorium distinction iron batteries and lithium batteries?

1, from the shape does not recognize, mainly depends on the corresponding batteries model specifications see discharge rate, which can be done with a battery-iron battery, you can do three yuan lithium battery protection board.

2, the battery can be identified from the appearance of the logo, the factory normal batteries have a "bar code" logo above covers a lot of information. But domestic manufacturers are often bad batteries, heartless children do bad things, vacuity, fraud and so on.

Tip: calculated energy density battery cells as follows.

Energy density (Wh / l) = capacity × volume plateau voltage ÷ ÷ 1000 (in terms of units)

Internet iron battery voltage: 3.2V; three yuan lithium plateau voltage is typically 3.7V.

Cylindrical volume = πr2; × h Rectangular volume = length × width × height
