Long Life Portable Rectangular Heat Resistance Span Flyeath Mobile Battery

In a nutshell, battery capacity is a measure of the energy it can store. When you test for capacity, you're looking at the battery's ability to deliver a specified amount of current at a constant rate to a specified voltage for a specified time. "Battery capacity" is a measure of the charge stored by the battery, and is determined by the mass of active material contained in the battery. The battery capacity represents the maximum amount of energy that can be extracted from the battery under certain specified conditions. Just like any other device, batteries need to be tested to determine if they are airworthy. That is, to determine if they will perform properly when required under normal conditions and more so when needed in emergency situations.
