I am just trying to find out if the current enters into the positive terminal of the battery (if there is a battery with bigger emf ) will it get charged and charge will be stored and current will not come out of the battery from the negative side or will it? No other conditions are given. Think and tell me.
There is too much confusion here to answer meaningfully. Current always flows through the battery. What goes in one end comes out the other.
Some types of batteries can be charged by forcing current thru them backwards. Those are called rechargable batteries. Others don't work that way and can be damaged by reverse current. Those are often called primary batteries. Which is which depends on the chemistry and the construction.
