Testing:

Engineered Power has a state of the art MACCOR cell testing unit. This equipment allows us to fully test the capacity of any cells we manufacture. Detailed records track the historical averages of capacity for every cell we make, and comparisons are done to ensure that the capacity is in line or better than specified in our cell rating sheets.

This equipment can also be programmed to do specific tests which can mimic what a specific application would require. A chamber which controls temperature to create more empirical results is part of the testing system. Additionally, the chamber can be used to create an environment more like that which the battery will see in the application.
The equipment allows us to test a cell down to a voltage of .3V per cell. Constant current range is between 1mA to 6A as well as pulse testing. We can record data points up to 5 per second. Several different tests can be programmed into one function. For example, a continuous
drain for a certain time period can be followed by pulses of varying currents and time durations. The number of available steps per test is up to 65 000.

Voltage, current, time, AH, and Wh are all parameters which can be tracked.
