Chapter 2: Pre-testing
Before you test a site with the analyzer, you need to
. Determine a reference value.
Note: make sure the battery you are testing is 12V batteries.
Reference values
Reference values are average conductance values from a sample of strong batteries similar in condition
and age. You can compare reference values to test the results from a group. The differences between test
results are reference values help you determine the capacity of the group to see if it is providing enough
conductances for the load. Differences can reflect how a group of batteries were treated, installed, or
maintained.
Options
Lancol recommends that you create your own reference values for a group of batteries to get values
specific to the group you are testing. For this reason, the following options are listed in the order you
should take to obtain a reference value.
1. Consult your company documentation for previous reference values that were created for the group
you are testing. If you do not have previous reference values for the site, do step 2.
2. Test a sample of battery. Refer to “Testing a sample of battery”. If you cannot test a sample of
battery, do step 3.
3. Test the battery in the group that you need to test with the analyzer and use highest conductance
value as a reference value. If you cannot test the battery for a reference value, do step 4.
4. Use the average from the group. Refer to “Using the average in the group”
Testing a sample of battery
To test a sample of battery for a reference value:
1. Choose at least 30 batteries from one manufacture with the same make, model, power rating,
age(within 6 months), and service history.
2. Record this information about the battery
.Battery manufacturer
.Model number
