We can maintain & repair all makes and types of equipment.

Many of the sites looked after by Exel have equipment from several different manufacturers. Over the years we have worked on almost everything you can come across in terms of standby battery equipment. We take pride in our versatility in this area. We have worked on sites as diverse as power stations, pharmaceutical and fertiliser plants, British Steel and government sites. Although the more day-to-day work is on sites such as hotels, universities, retail stores, hospitals and local authority premises.

By virtue of training and experience, our engineers can correctly test your battery system, and have the expertise to interpret the results properly. It is important to have a full understanding of how a system is supposed to operate in order to properly test it and know it is doing what it is supposed to do. Failing the mains and seeing if the lights work is not sufficient. 

For example, all duration tests are data logged. The result is time and date stamped from the test PC. The time/date is tamper-proof so a 3 hour test actually is a 3 hour test, the logged graph being the proof. In addition, the graph shows if the test was a pass, a failure, or if any cell failures occurred (please see the sample test results graph).
