The instruction is taken, apparently, from some article about charging batteries. It is described how to calculate the charge time depending on the current charge (how to apply this given that the charger is "smart"?), Safety precautions and other useless "water". Everything related to this charger - 1 picture. Its pros: Works Probably really smart charging. At least the first time it really does not charge (when the test is in progress). Has cons: Completely useless guide. Charges for a very long time. Not informative indicator of work
