There are two types of battery ller cap used
on battery cell:
1) Filler cap with buoy
proper electrolyte
liquid leveL
Battery
Add distilled water, red buoy will float until
while rod appears under the red scale.
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 oat up and resulting in excessive lling.
2) Filler cap without buoy
When adding water, stop lling 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.
1.3.3 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, specic 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 specic
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.
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, specic gravity of electrolyte (under 30°C) should be around
1.14.
