Computerized Battery Analyzer (CBA)
The CBA 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 V. 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. (more... About CBA)

The West Mountain Radio CBA Charger can be used with a West Mountain Radio CBA IV and a user provided battery charger to automate life cycle tests, automatically alternating between periods of charging the battery and discharging the battery. By automatically switching between charge and discharge cycles of the battery, a hands-free lifetime test of the battery can be performed.
Test at 5 times the power with a CBA amplifier in between a CBA and your battery.
- 500 watt discharge with a single amplifier
- 1000 watt discharge with two amplifiers and harness
- 2000 watt discharge with four 20X* amplifiers and harness
- Designed for commercial or industrial use.
- Test a Lithium cell at up to 120 A / 500 W with a single amplifier
- Test a Nickel cell at 160 A regulated down to .9 V with a single amplifier
- Test large batteries at high discharge rates
- Test small batteries at or near their current and temperature limits
*20X amplifiers are a special order item.
The CBA software is easy and intuitive to use. It provides automatic sensing of the battery cell count and recommends a safe maximum discharge current and minimum safe cutoff voltage for your batteries. The system of software and hardware is designed to protect both the CBA and the batteries that are tested.
- Standard software free with unit

CBA III Only
Multi CBA Software Upgrade License for Production Testing of Batteries
- Single computer license for up to twelve CBA IIIs
- Simultaneous battery testing saves valuable technician time
The CBA is capable of higher test rates than other testers: up to 40 A or 150 W, which ever is higher. It not only tests the total amount of energy stored in a battery (capacity in amp-hours), but it graphically displays and charts voltage versus amp-hours.
Unlike a resistor load, it has an electronic constant current load that is controlled both with software and electronics. Constant power tests may be done with the Extended Software.
Graphs may be displayed, saved and printed. Multiple graphs of the same battery, or multiple batteries, may be compared or overlaid, a very useful feature. Battery tests may be printed on a color or black and white printer. You may also print convenient test labels to be placed directly on your batteries to remember the last time they were tested and how they performed.
A CBA will measure the temperature of a battery under test using the optional external temperature probe. The temperature probe will provide automatic over-temperature shutoff at a preset or user selected temperature limit. Battery temperature may be graphed with the Extended Software.
The CBA uses a high grade Powerpole® battery connector and comes with a 13 gauge pigtail lead for which adaptors may be made, or purchased as an accessory to connect a battery. A CBA is ruggedly built, compact and has a high performance cooling system with a quiet fan. LED indicators show test status from across a room.
The CBA uses an on-board microcontroller. Each CBA is computer calibrated for high accuracy. The electronic load uses a pulse width modulation system to control a pair of power MOS FET transistors using both electronic and software current regulation. The on-board microcontroller also provides the USB interface to the computer.
The software supplied with the CBA is easy and intuitive to use. It provides automatic sensing of the battery cell count and recommends a safe maximum discharge current and minimum safe cutoff voltage for your batteries. The system of software and hardware is designed to protect both the CBA and the batteries that are tested.
We think that you will find the CBA a useful and essential tool for anyone that depends on batteries in critical applications. You will learn new and valuable information about your batteries that cannot be determined any other way. Using batteries without a CBA is like driving a car without a gas gauge.
