Optim Engineering’s Computerized Battery Analyzer III (CBAIII) can test virtually any type or size of battery, any chemistry, and any number of cells up to 55 V. Capable of higher test rates than other analyzers, CBAIII can test up to 40 amps or 150 watts, whichever is higher. With accessory amplifiers, testing may be possible at up to 2000 watts. The device allows anyone to scientifically test batteries, letting a computer do all the work. According to Optim Engineering, CBAIII provides the only easy, inexpensive, and accurate way to determine the total amount of energy stored in a battery. The CBA uses a standard PC with sophisticated software to test in a safe and user-friendly way. The software graphically displays and charts the battery capacity in voltage vs. amp-hours, minutes, or watt-hours. Accessories include battery connection cables and holders, battery temperature probe, 500 watt 10X amplifier, a pro software upgrade, and pro calibration-verified hardware.
