BATTERY ANALYSIS TOOLS
When your battery performance reduces, your service provider could help you to locate the
problem. In this section you can find tables that could help you track your battery’s performance.
If you copy these blank pages you can use them more than once.
To be able to quantify the performance it is adviced to perform a field test, measuring range and
voltages. The drive logging form can be used for this.
Measuring each battery cell can be done to determine which specific cell underperforms. Each
measurement can be filled in the battery logging form. Appropriate values can be found below.
