Using The New Recommendations
A new maintenance-free battery can normally be installed in a machine without charging and load testing. However, if a battery has been in storage for a long time, it can be partially discharged. Do the following steps before installing a maintenance free battery.
1. Measure open circuit voltage with a 6V7070 Multimeter with the selector on the 20 volt DC scale.2. If open circuit voltage is 12.40 volts or more, the battery can be installed.3. If open circuit voltage is less than 12.00 volts, do NOT sell the battery as a new battery.4. If open circuit voltage is 12.00 to 12.39 volts, charge the battery. Select the amps charge rate and the charging time from the following tables.
During charging, on-charge voltage must not exceed 16.0 volts. In order to keep on-charge voltage below 16.0 volts, charging amps may need to be reduced near the end of charging.
5. After charging, load test the battery at one-half the cold cranking amp (CCA) rating of the battery. Refer to PEKP9100 for CCA rating. If the voltage at 15 seconds is 9.5 volts or more, install the battery. If the voltage at 15 seconds is less than 9.5 volts, do NOT sell the battery as a new battery.
