When coupled with a higher chemical age, the impedance increase will be more significant. A battery’s impedance will temporarily increase at a low state of charge and in a cold temperature environment. A battery's impedance can increase if a battery has a higher chemical age. A battery with a high impedance may be unable to provide sufficient power to the system that needs it. One attribute that affects this instantaneous power delivery is the battery’s impedance. In order for a phone to function properly, the electronics must be able to draw upon instantaneous power from the battery. In addition, a battery’s ability to deliver maximum instantaneous performance, or “peak power,” may decrease. This can be referred to as the battery’s maximum capacity-the measure of battery capacity relative to when it was new. All rechargeable batteries are consumable components that become less effective as they chemically age.Īs lithium-ion batteries chemically age, the amount of charge they can hold diminishes, resulting in shorter amounts of time before a device needs to be recharged.
