Understanding 2000mAh Lithium Ion Batteries

Before we get into the nitty-gritty of pricing, let's quickly cover what a 2000mAh lithium-ion battery actually is. The "mAh" stands for milliampere-hour, which is a measure of the battery's capacity – basically, how much energy it can store and how long it can power your device. A 2000mAh battery should, theoretically, be able to deliver 2000 milliamps of current for one hour. In practice, it's a bit more complex than that due to voltage, discharge rates, and other factors, but that's the general idea.

Why Lithium-Ion? Lithium-ion batteries are popular because they have a high energy density, meaning they can store a lot of power in a relatively small size. They also have a low self-discharge rate, so they hold their charge well when not in use. Unlike older battery technologies, lithium-ion batteries don't suffer from the "memory effect," so you don't have to fully discharge them before recharging.

Common Uses: You'll find 2000mAh lithium-ion batteries in a wide range of devices, including:

• Smartphones: Often used as the primary battery in smaller or older smartphone models.
• Portable Gaming Devices: Perfect for handheld consoles where size and battery life are crucial.
