9.0 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.
10.0 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. Designate as
the pilot cell the cell with the lowest cell voltage in the series string following the initial charge.
Pilot cell readings serve as an interim indicator between regularly scheduled voltage and
gravity readings of the complete battery. The temperature sensor should be connected to
the negative post of the pilot cell.
Read and r
ecord the pilot cell voltage on a monthly basis between regularly scheduled
individual cell readings.
11.0 MAINTENANCE
Batteries lose some initial charge during shipment and storage. Depending on storage time, a
battery may r
equire a freshening char
ge. See Section 4.0 for battery storage times.
11.1 Battery Cleaning
Obser
ve the battery for cleanliness at regular intervals. Keep cell terminals and connectors free
of corrosion. Terminal corrosion could adversely affect the performance of the battery, and it
could pr
esent a safety hazar
d.
11.1.1 Standard Cleaning
To perform a standard cleaning of the battery, follow the procedures below:
1. Disconnect the battery
.
2. Wipe off any accumulation of dust on the cell covers with a cloth dampened in clean
water
.
Do NOT use any type of oil, solvent, detergent, petroleum-based
solvent or ammonia solution to clean the jars or covers. These
materials will have an adverse affect and cause per
manent
damage to the battery jar and cover and will void the warranty.
