Computerized Battery Analyzer CBAIII

Our CBAIII (Computerized Battery Analyzer) is much more than a simple battery voltage tester or a battery load tester. Unlike a simple load tester the CBA will test virtually any type or size of battery, any chemistry, any number of cells up to 55 volts. For the first time and for a reasonable price, anyone can do scientific tests of their batteries by letting their computer do all the work.

The CBA is capable of higher test rates than other analyzers: up to 40 amps or 150 watts, whichever is higher. With accessory amplifiers you may discharge at up to 2000 watts!

It not only tests the total amount of energy stored in a battery (capacity in amp-hrs), but it graphically displays and charts voltage versus amp-hours.

A PWRgate is a 12 volt backup power system that can supply up to 40 amperes continuously from either a power supply or a battery, and it charges the battery with its high performance charger. Connected equipment instantly switches from the power supply to battery power during an AC failure: no glitches.

PWRguard protects the equipment, the power supply and the battery from damage. It is an automatic safety switch that is inserted between a power source and the load. It switches OFF whenever the voltage is over 15 volts or under 11.5 volts.
