Preventative Maintenance (PM)

Both IEEE standards and NERC standard PRC-005-02 reference battery testing/maintenance guidelines. Battery manufacturers also publish testing requirements ensure warranty compliance.


SBS will test and provide detailed reports that will comply with all requirements.

Load Tests

Load tests are the most accurate way to determine the state of health of your battery. Load tests are also very time consuming – they typically require that the system be shut down and taken offline and also require special equipment.


SBS can perform IEEE load tests based around your requirements. As an option we can provide temporary power so that your system does not have to be shut down. After the load test is completed we provide complete reports that will comply with NERC standard PRC-005-02.

Battery Test Equipment

Companies often subcontract battery testing because of a lack of manpower, or because people believe that this work is difficult. If you have the manpower to do your own testing you can save a very significant amount of money each year by purchasing your own battery testing equipment!


SBS has been selling battery test equipment for nearly 30 years. We were the first company to introduce a digital hydrometer to the North American market and today we continue to develop innovative, unique products that allow any technician to do their own testing and reporting.


Experience in this market is what sets us apart from our competition. We have technicians on staff with decades of experience both in the office and in the field. They are able to repair and calibrate battery test equipment and are also available to provide training and support whenever it is needed.


Our test equipment allows users to maintain reliable battery systems and to ensure compliance with applicable industry regulations.
