Collection: Batteries & rechargeable batteries

There are rechargeable batteries and disposable batteries in different sizes such as AA, AAA and lithium-ion batteries. Rechargeable batteries are ideal for devices that require frequent power, while disposable batteries can serve as an emergency backup.

Lithium-ion batteries offer higher energy density and are lighter, making them ideal for mobile devices and power banks. NiMH batteries are more robust and are well suited for devices with consistent energy consumption, but they are heavier and have lower energy density.

Batteries and power banks lose capacity over time and should be replaced when the charging cycles decrease significantly or the battery life is greatly reduced. The lifespan of lithium-ion batteries is usually between 2-5 years, depending on care and use.
