Your Dell laptop computer came with a long cord that connects your computer to a wall outlet. This is the cord that you will use to enable battery charging on your laptop. The removable battery that also came with your laptop does not have an infinite amount of charge, which means that occasionally it will need to be replenished. The time it takes to recharge a battery will depend on the capacity of your unit.
