West Mountain Radio CBA IVThe Ultimate Battery AnalyzerThe West Mountain Radio CBA IV is the best way to scientifically analyze the performance and specifications of a battery. Using powerful proprietary software the CBA IV offers constant current battery capacity tests and provides visual charts for examination. The discharge current of the battery can be regulated via the software so that various levels can be tested with the same device. The CBA IV is capable of testing a wide variety of batteries, ranging from button cells to automotive batteries. The included software has presets for common types such as NiCd, NiMh, Lead Acid, Li-Ion, Li-Poly, Alkaline, Carbon Zinc and Mercury. New the CBA series of analyzers is the ability to profile solar sells with performance readouts like the ones provided for batteries. Another new feature is the ability to test even smaller batteries, down to as low as 10 mA.Safety FeaturesTesting batteries by putting them under an electronic load is serious business, and the CBA IV is designed with a contingency plan for any possible point of failure. The unit has built in fail safes that protects against anomalous temperature, current or power fluctuations. In the event of a computer crash the device will automatically shut down to prevent cell failure. Discharge rates can be set between 0 to 40 amps, so users can specify the exact rate at which the battery discharges to match the specifications of their battery and test. The unit will automatically shut off at the end of tests based on either software recommendations or selected discharge voltage. The unit will also automatically shut off in the even of unexpected temperature variation with the use of an optional magnetic temperature sensor. Easy To UseWhile such a sensitive device might seem daunting to use, the CBA IV software is designed for ease of use so that even casual users can easily test their batteries safely and accurately. Battery cell chemistry, number of cells and the current testing current can all be set manually and the software will recommend appropriate tests based on the provided information. The software will set up graphs for all of the tested statistics including voltage, current, amp hours, watts and temperature (with the use of optional temperature probe). Test results can be saved to a computer or printed out for further review or professional displays.
