With proper storage, these rechargeable batteries are long-lasting, durable, and have many possible charging cycles. Li-ion batteries are used in various high-energy portable devices such as smartphones, notebook computers, cameras, and electric power tools. These batteries can also be used in radio-controlled models and telecommunications applications.
