- Add only distilled water.
Before adding distilled water, check if the
buoy can move up and down properly to
prevent the buoy from failing to float up and
resulting in excessive filling.
2) Filler cap without buoy
When adding water, stop filling when the
electrolyte level is higher than the protective
plate for 15~20 mm.
Please operate the electric watering device in
accordance with its operating manual.
B1-3.3 Monthly Maintenance
-
-
Before the charging is completed (while
the charger is still energized), measure and
record the voltage of battery cell the entire
battery;
After the charging is completed, measure
and record the electrolyte concentration and
temperature of the battery cell.
How to tell if the battery is normal?
-
As for a normal set of fully charged batteries,
the voltage of each of the battery cell
should be around 2.08V, specific gravity of
electrolyte should be around 1.28;
After being fully charged, if the voltage of
battery cell is lower than 1.85V or the specific
gravity of electrolyte is less than 1.05, then that
battery cell has been damaged and needs to be
replaced.
And you can identify if the battery is fully
discharged according to the specific gravity of
battery electrolyte when the instrument alarms,
and identify if the capacity indicated on the
instrument is accurate.
If there is fault, please notify service personnel for
repairs.
B1-3.4 Care
-
-
Battery surface should be clean and dry to
prevent the occurrence of leakage currents;
Battery cables, terminals and connectors mu-
st be tightened and clean, a small amount of
special grease should also be applied.
1. Keep it clean
-
-
-
-
Do not use a dry cloth or fabric to clean the
surface of the battery, so that to prevent the
occurrence of static electricity, resulting in
explosion;
Unplug the power plug;
Wipe clean with a damp cloth;
Please wear goggles, rubber boots and
rubber gloves.
2. Make sure that the cable insulation is not da-
maged and the connection layer has no signs
of heating.
-
As for a group of normal batteries, when the
battery is discharged for 80% (the instrument
alarms and prompts low battery, you should
recharge in a timely manner), the open circuit
voltage should be around 1.93V, specific
gravity of electrolyte (under 30°C) should be
around 1.14.
