density control work, cleaning of the battery and lead-out piles, etc., which can
effectively extend the service life of the battery.
Check for water in the battery box and find that the water must be drained
immediately.
In addition, the battery should not be stored with electrolyte. If you want to
store the used and fully charged battery for a short period of time, charge it
every other month during the storage period to compensate for the
self-discharge of the battery and prevent the battery plate from being vulcanized
or eliminated. The battery plates are slightly vulcanized, and the battery
condition is often checked.
When the battery is in use, if it is not fully charged and fully discharged, a
full discharge full charge should be performed every month. This keeps the
capacity of the battery and avoids sulfate of the plates.
Keep the outside of the battery clean
Check the fixing of the battery and the lead wire clamp, there should be no
looseness.
Check the battery case for cracking and damage, and the pole and lead chuck
should be free from burning.
Wipe the external dust of the battery with a cloth. If there is electrolyte on the
surface, wipe it off with a cloth or rinse it with hot water, then wipe it with a
cloth. Remove dirt and oxide from the pole head, wipe the outside of the cable
and the lead clamp to remove dirt. Unblock the filler cap vent and clean it. Apply
a thin layer of industrial petrolatum to the pole and lead chuck during
installation.
Check the height of the battery level:
A glass tube with an inner diameter of 0.2in to0.3in and a length of about
5.9in can be inserted vertically into the liquid addition port until the edge of the
pole plate, then the upper mouth of the tube is pressed with a thumb, and the
glass tube is clamped with the index finger, the middle finger and the ring finger.
The height of the electrolyte in the glass tube is the height of the electrolyte in
the battery above the plate, which should be 0.6-1in. Finally, the electrolyte is
played back into the original cell.
