Shockbox SB24-00-EBA - Electronic Battery Analyzer (EBA)

The ShockBox Electronic Battery Analyzer (EBA) is a computer-controlled test box engineered to perform detailed capacitance testing on small aircraft emergency power supplies and standby battery packs, including PS-835, PS-850, PS-855, RG-125, RG-126, and similar models. It automates the test process by connecting to a Windows PC via USB, allowing the software to control the load application, monitor performance, and record results without constant technician supervision. This makes it well-suited for aviation maintenance shops, avionics labs, and other facilities that need dependable battery health data. By freeing technicians from manual monitoring, the EBA supports efficient use of bench time and helps reduce aircraft downtime.

The EBA includes custom software that guides the user through test setup, displays real-time graphs of battery performance, and generates PASS/FAIL results and capacitance percentages upon completion. Test parameters such as load and duration can be set in the software, which then manages the test automatically, sounding alerts when the test finishes. The software also allows printing of detailed test reports, which are valuable for recordkeeping and maintenance documentation. This automation helps ensure consistency and accuracy across multiple battery tests.

The Electronic Battery Analyzer is designed specifically for small standby power supplies and battery packs commonly found in aviation and similar applications. It supports a wide range of emergency power units, including PS-835, PS-850, PS-855, RG-125, RG-126, and related models, making it versatile for shops that service different aircraft types. The included harnesses – an adapter for PS-series units and a universal harness – expand its capability to connect to various battery configurations, increasing the analyzer’s flexibility. Slightly larger battery packs can also be tested, although they may require longer test times.

By automating key parts of the capacitance test process, the EBA lets technicians start a test and then move on to other tasks while the analyzer runs in the background, reducing idle bench time. The USB interface to a PC allows the test to be monitored remotely, with results logged automatically, eliminating the need for a technician to monitor the discharge manually. The system’s alert features notify the user when a test is complete, further minimizing hands-on time. These capabilities help maintenance teams manage workflow more efficiently, particularly when handling multiple power supplies in a busy shop.

The EBA comes with two wire harnesses: a dedicated adapter cable for PS-series power supplies (e.g., PS-835, PS-850, PS-855) and a universal harness that extends testing capability to other small batteries and power modules. These harnesses simplify connections and ensure compatibility with a variety of units without requiring custom wiring or adapters. The front panel jacks also allow connection to a DC bench power supply for charging between test runs. Having these accessories included means the analyzer can be deployed quickly in maintenance workflows without sourcing additional components.

The EBA enables maintenance shops and avionics facilities to perform accurate, repeatable battery tests in-house, eliminating costly and time-consuming outsourcing of battery testing. By providing detailed results and PASS/FAIL output, technicians can make informed decisions on whether a battery or power supply needs replacement or reconditioning. This precision helps avoid unnecessary part removals and replacements, which can inflate maintenance costs over time. The ability to test multiple battery types with a single analyzer also reduces equipment investment overhead.

Yes. The EBA’s software produces clear PASS/FAIL reports and capacitance data that can be printed and archived for maintenance logs, helping support documentation requirements and regulatory compliance. Detailed test results provide traceable proof that required battery tests were performed under controlled conditions, which can be important during audits or quality checks. Having documented test evidence also aids historical trend analysis, helping maintenance planners recognize performance degradation over time.

Traditional manual battery testing requires a technician to observe discharge tests, manually time load application, and calculate capacity based on observed voltage changes – a process that is time-intensive and prone to human error. The EBA automates the discharge process by managing load application and data capture through software, improving both accuracy and repeatability. The USB connection to a PC allows real-time monitoring and automated recording of results, making it easier to manage multiple tests with minimal personnel involvement. As a result, the EBA offers a more efficient and reliable alternative to manual methods.

While the EBA is primarily designed to test aviation emergency power supplies and standby battery packs, its universal harness and adjustable test parameters make it useful for other small DC power systems in industrial or transportation applications. Provided the battery or power module’s specifications are known and compatible with the analyzer’s load and interface capabilities, technicians can use the EBA to assess capacitance and performance in similar systems outside of aircraft maintenance. This versatility can be especially helpful for shops supporting mixed equipment fleets.

For operators supporting business jets, regional aircraft, or charter fleets, the EBA provides a reliable way to regularly monitor the health of standby batteries critical to emergency systems. Performing routine capacitance tests with consistent, documented results helps identify weak or failing power supplies before they cause operational issues or AOG (Aircraft on Ground) situations. The EBA’s computer-managed testing reduces technician workload while ensuring that performance criteria are met across a range of battery types. This proactive approach can contribute to improved fleet readiness and reliability over time.
