The article presents information on rechargeable batteries. The ready light should eventually illuminate, indicating the battery is fully charged. However, the ready light doesn't guarantee a good battery; nor does it assure sufficient runtime. It only indicates the battery is fully charged on whatever space that was available to fill. The rechargeable battery is a corrosive device that gradually loses the ability to hold charge. In the first year, a battery-operated system works well because the batteries are fresh. During the second year, some batteries start losing capacity and reliability begins to decline.
