Hello Friends,

How can find that how much time one battery requires to be fully charged?

My circuit is like I am giving 8V with 51Ohm resiter in series.

So if I am not wrong depend on how much battery is charged the current will flow from Power to battery.

but how can I calulate the time? I mean what is the equation to calculate the time?

where can I find its information?

There are a number of factors that must be considered when charging a battery. Things like battery chemistry, temperature, amp-hour rating, etc.

You can take a look at the information at Battery University for the answer to your specific battery charging application.
