Centurion 4987 Portable Generator User Manual


 
To recharge 12 Volt batteries, proceed as follows:
Check fluid level in all battery cells. If necessary, add ONLY
distilled water to cover separators in battery cells. Do not
use tap water.
If the battery is equipped with vent caps, make sure they are
installed and are tight.
If necessary, clean battery terminals.
• Connect battery charge cable connector plug to panel
receptacle identified by the words "12-VOLT D.C."
• Connect battery charge cable clamp with red handle to the
positive (+) battery terminal.
Connect battery charge cable clamp with black handle to the
negative (-) battery terminal.
Start engine. Let the engine run while battery recharges.
Engine idle control switch must
be in off position for battery
charging.
When battery has charged, shut down engine.
Note: Use an automotive hydrometer to test battery
state of charge and condition. Follow the hydrometer
manufacturer's instructions carefully. Generally, a
battery is considered to be at 100% state of charge
when specific gravity of its fluid (as measured by
hydrometer) is 1.260 or higher.
