Read and observe the following instructions:
The charger seems to be suitable for several battery models. Therefore, it has 2+ and 1- contacts (labeled).
The Series NP-BX1 battery has a lot of game in the device, and thus can be inserted easily wrong.
Therefore, always make sure that the information on the contacts of the battery, exactly the same as the contacts of the charger, and insert the battery accidentally upside down.
Pay attention also closely that not the battery slip left or right, as bask the bottle contacts with electricity can be supplied and the battery can thereby be destroyed.
Also you should keep the charging LED close eye because the manual provides no indication of a trickle charge, or an overload protection. Disconnect, therefore, the charger after charging from the mains immediately and remove the battery promptly.
