A micro USB rechargeable battery AA with a capacity of 400mAh is a specific type of rechargeable battery designed to replace traditional disposable AA batteries. This rechargeable battery is built with a micro USB port for convenient charging using a compatible micro USB cable.
The AA size refers to the physical dimensions of the battery, which closely resemble a standard AA battery. However, unlike disposable batteries, this rechargeable battery can be reused multiple times by recharging it when its power is depleted.
The 400mAh capacity indicates the amount of energy the battery can store. In this case, it has a capacity of 400 milliampere-hours, which determines how long the battery can power devices before needing to be recharged. Higher capacities generally provide longer runtime.
To recharge the micro USB rechargeable battery AA, you would typically connect it to a power source using a micro USB cable. This could be a USB port on a computer, a USB wall adapter, or a power bank. The micro USB port on the battery enables convenient charging without the need for a separate charger.
Micro USB rechargeable batteries offer a more sustainable and cost-effective alternative to disposable batteries since they can be recharged and used multiple times. It's important to note that the charging time and lifespan of the battery can vary depending on the specific brand and model.
