Question
Hello
I bought a battery charger and want to know how I calculate charging time.
On its introduction was written above formulate:
Charging time (hour):  1.5*battery capacity (mAh) divided by charging current
And now I know what a battery capacity is but don't know what is charging current
Please tell me what it is
Best wishes  

Answer
Apa,

Hello. Thanks for the question.  Before I answer, I am compelled to say something.  This question is not appropriate for the "cameras" catagory.  I only bother to tell you this because I get a lot of questions that are outside my area of expertise.  This question is more for someone who is an electrician.  I could ask the rep from the camera company this question and he wouldn't even know it.  However, it just happens that I used to be an electrician in the Navy and know how to find the info you needed:

All the info you need is supposed to be provided with the charger.  The capacity, as you've discovered is written in mAh (milliAmp hours).  Current should also have been provided for you and it is simply written in mA or milliAmps.  If it isn't written somewhere for you, you will need to contact the maker for it.  Oh, and you can find a charge calculator here:
