A rechargeable battery is an energy storage device that can be charged again after being discharged by applying DC to its terminals.

This is true even factoring in the higher purchase price of rechargeables and the requirement for a charger. Also, Rechargeable batteries allow for multiple usages from a cell, reducing waste and generally providing a better long-term investment in terms of dollars spent for usable device time.

A rechargeable battery is generally a more sensible and sustainable replacement for one-time-use batteries. But The anode in a rechargeable battery gets consumed as well but at a slower rate, allowing for many charges and discharges.

In use, rechargeable batteries are the same as conventional ones. However, after discharge the batteries are placed in a charger or, in the case of built-in batteries, an AC/DC adapter is connected.
