Prerequisites:
Before installation please make sure that you meet the minimum basic pre-requisites. Today's PC definitely meets the requirements. But if your pc is more than 6 years old, you may want to reconfirm the hardware and software requirements.

Hardware / PC: A PC with USB Port, 128 MB of RAM or more, Windows 98 or higher version of operating system, 233 MHz processor or higher and about 10 MB of free hard disk space for installation.

Software Installation:
Installation: The installation of CBA is very simple. Just follow the steps and you are ready to go.

  • Insert the accompanying CD in to the CD drive, the CD should auto run and prompt you with 5 options
  • If the auto run is disabled, you can browse the CD through windows explorer and double click on auto run file
  • Once the auto run application starts, choose "Software & Hardware installation option"
  • You will now be asked to connect USB cable between PC and CBAII
  • As soon as you connect windows will auto detect West Mountain Radio - Computerized Battery Analyzer hardware and prompt you for installing drivers
  • You should then choose CD ROM as the location of drivers and allow the driver installation to complete. On some PC's especially on Windows XP based PC's you will be prompted to verify / confirm to installed unsigned driver. You have to use "Continue Installation" Option to continue. Follow the steps to complete the driver installation returning to auto run window
  • Use the 5th Option to install the West Mountain Radio Test software
  • Follow easy to understand steps to complete testing software installation
  • You are now ready to analyze and test batteries
  • Please read through the included electronic manual before performing steps. Do not forget to go through safety precautions prior to beginning the tests
Tests:
Let's begin some testing. But before that, you MUST read the user manual completely. Here are a few important tips

Tips for Testing batteries with CBA II:
  • ALWAYS Connect CBA II through USB to PC prior to connecting batteries
  • DO NOT Connect battery with wrong polarity
  • Ensure that battery terminals are clean and battery is making firm contact with the battery holder/adapter
  • Also ensure that the electrical path has no or minimal resistance and connections to power poles are firm
  • DO NOT Short the battery or the CBA II power connectors at any point of time
Sanyo 2000 mAh NiMH Battery Test: The first step was to charge the batteries. The batteries were charged using La-crosse BC-900 charger with charging current set at 1 Amp. All four batteries were given rest for 2 days prior to caring out the tests. Each battery was tested individually with a discharge current of 1 Amp and cutoff voltage of 0.9 volts. Prior to the test the assumption was that all batteries are having same charge and they are in same health. However after the tests, it is now clearly proven that battery 003 and battery 004 are under performing where as battery 001 and 002 are near their full capacity. Below comparative graph depicts the fact very clearly.


This way you can clearly match the good pair of batteries and identify under performing batteries.
