Batteries and Extended Battery Packs

Batteries and battery packs are devices that store energy and convert it into electrical energy. Batteries are used to power a wide range of devices, from small electronics like smartphones to larger systems like uninterruptible power supplies (UPS) and electric vehicles. They can be classified into primary (non-rechargeable) and secondary (rechargeable) types, with common examples including lithium-ion, lead-acid, and alkaline batteries.
An extended battery pack refers to an enhanced battery system designed to provide extended power duration compared to standard batteries. These packs often consist of multiple battery cells that are added to a device to increase its runtime or operational life during power outages. In the context of UPS systems, an extended battery pack is typically an additional module that connects to the main unit, offering prolonged backup power for critical equipment by increasing the total energy storage capacity.
