Battery Testing
Aside from all those who jump into a post designed for me to answer I will answer your question.
Batteries should only be tested for problems in a way that is precise and time consuming.
!- battery pack is to be brought to a completed charge with your charger.
2-Using a chart the testing and data recording starts now. Both voltage of the battery pack and individual batteries are tested and recorded.
3-A machine called a draw down unit is than place on the system. This machine reads the voltage and time factor of the battery pack while the amperage draw is simulating a cart driving 15-18 MPH.
4-After this machine draws the batteries down to a safe voltage discharge level (test takes 45 min to 150 min)a finel test is performed on each battery and that will isolate each battery and show any loss of voltage under a final load, the results are logged to the chart for the correct analysess of the system is known.
In summery this process is time consuming as you can see as you can see and would be almost impossible for a tech that comes to your home to perform unless you're serving lunch. That being said we always test systems in our shop and try to be as accurate as possible presenting the results in an accurate chart form and present the necessary repair correctly.
This testing system is performed by many shops in this area and has proved itself to be accurate.
Hope this helps,
