10.0 BATTERY TAPS
Connections made to a battery for tapping a certain group of cells to provide a voltage other
than the total battery voltage is NOT recommended and can void the warranty
. Tapping results
in an imbalance of the system during charging and discharging, causing unsatisfactory
operation.
11.0 PILOT CELL
One cell in a battery is usually selected as a pilot cell. It becomes an indicator of the general
condition of the entire battery with regard to voltage, gravity and temperature. Pilot cell readings
serve as an interim indicator between regularly scheduled voltage and gravity readings of the
complete battery. A cell near the middle of the battery layout is usually the best selection, as it
will have the most representative temperature. This cell should be used for the charge controller
temperature probe for voltage correction.
Because a small amount of electrolyte may be lost in taking hydrometer readings, you should
select a different cell as the pilot cell annually.
Read and record the pilot cell voltage on a monthly basis between regularly scheduled
individual cell readings.
