These rechargeable batteries power a variety of devices, including cell phones, laptops, e-bikes, and electric vehicles. They are lightweight, feature high energy density, and can endure numerous charge and discharge cycles.

Lithium batteries can pose safety risks if mishandled, potentially leading to fires and explosions. They should never be disposed of in regular trash or household recycling. Instead, consider reusing, donating, or recycling them with the proper authorities to minimize their environmental impact. Recycling lithium-ion batteries conserves natural resources, reduces air and water pollution, and helps prevent greenhouse gas emissions.

mAh stands for milliampere-hour, a unit that measures a battery's capacity. It indicates how much charge a battery can hold and how long it can power a device. For example, a battery rated at 1000 mAh can theoretically provide 1000 milliamperes (or 1 ampere) of current for one hour before it needs recharging. Higher mAh ratings typically mean longer usage times for devices.
