Power Thru-opladers

A rechargeable battery is designed to be reused multiple times by recharging instead of throwing it away after single use. They are commonly used in various electronic devices such as smartphones, laptops, cameras, and portable gaming consoles. Rechargeable batteries are more environmentally friendly and cost-effective in the long run compared to disposable batteries.

AA rechargeable batteries typically output 1.2-1.5 volts per cell when fully charged. NiMH AA batteries provide around 1.2V. Lithium-ion AA batteries give around 1.5V per cell. Check manufacturer specs since voltage varies by chemistry and capacity.

The most common rechargeable battery types are nickel-cadmium (NiCd), nickel-metal hydride (NiMH), sealed lead-acid, and lithium-ion (Li-ion). Other rechargeable types include nickel-zinc (NiZn), nickel-iron (NiFe) batteries and lithium-ion polymer (LiPo) batteries which are normally used in powerbank and smartphones nowadays. Not all standard sizes like AAA, AA, C, D are available for every chemistry.

mAh stands for milliampere-hour and is a unit of measurement used to indicate the capacity of a rechargeable battery. It represents the amount of charge a battery can deliver over time. Higher mAh ratings generally mean longer battery life, as they indicate a larger capacity to power a device before needing to be recharged.
