The proven method for determining whether a battery will perform is to test it under load conditions. Proper load testing is the only way to determine where the battery resides on its expected life curve. Sys-Tek owns and uses the Albér BCT-2000 battery capacity test system. Load testing is essential for any storage battery system that protects equipment or a critical service. Because the battery is almost always the least reliable component, load testing should be done on a regular basis to ensure reliability.
The BCT-2000 is a combination load control and data logging system, consisting of a data acquisition module and a laptop computer data logging unit. The data acquisition module acquires all cell voltage, overall string voltage, and current readings. The computer data logging unit displays the programming parameters for the test. During a load test, the system records overall voltage, load current, and cell voltages.
