INSPECTION & INITIAL CHARGE OF FLOODED
LEAD-ACID BATTERIES
WARNING
• ALWAYS WEAR THE PROPER PERSONAL PROTECTIVE EQUIPMENT
(GOGGLES, GLOVES, CLOTHING) WHEN HANDLING FLOODED BATTERIES
AND ELECTROLYTE.
• WET BATTERIES MUST BE FULLY CHARGED BEFORE BEING DELIVERED
TO THE END USER.
• UNLESS INSTRUCTED BY ROLLS TECHNICAL SUPPORT, NEVER ADD ACID
TO THE BATTERIES AT ANY TIME. USE DISTILLED WATER ONLY.
FAILURE TO
FOLLOW THESE INSTRUCTIONS MAY RESULT IN MALFUNCTION
AND WILL VOID WARRANTY.
A battery may not be fully charged when received. An initial charge brings the battery
to an operational state. Before charging, inspect for physical damage, check polarity
and electrolyte levels in each cell. Ensure the electrolyte (liquid) covers the plates
completely. It is normal for electrolyte levels to lower as the battery case will relax
(bulge) slightly after filling. If the plates are exposed, add distilled water until all are
just submerged. It is important not to overfill each cell as the electrolyte level will
rise during the charging process. Charge voltages are indicated in Table 2 (a & 2 (b
Flooded Charging Parameters.
INITIAL INSPECTION & CHARGING
1. I nspect the batteries for damage. Important: read all warning labels on batteries
b
efore proceeding.
2. Flooded batteries are fully charged and tested before shipping. However, deep cycle
batteries will self-discharge when not in use during transportation and storage. Upon
installation, the initial charge brings the battery to an operational state. Before this
charging process, electrolyte levels should be checked, making sure the plates are
covered in each cell. If required, add distilled water until the plates are fully submerged.
It is important not to overfill as the electrolyte level will rise slightly during charge.
3. Check for correct polarity. Attaching the positive and negative voltmeter lead to the
positive and negative battery terminal should provide a positive voltage reading. If it is
negative, a reverse polarity condition exists and you should contact your dealer or
Rolls Battery Technical Support to advise.
4. Place batteries on charge. Please see Table 2 (a & 2 (b Flooded Charging Parameters
for required charging parameters. Do not let the cell temperature exceed 52°C (125°F). If
the temperature becomes excessive or the cells begin to gas vigorously, reduce the
rate of charge. Continue charging until all cells reach the specific gravity of the filling
acid. All cell specific gravities should be even (1.260-1.280) when resting at full charge.
