4) Always add distilled water
regularly for ordinary lead-acid
batteries. It is preferred to properly
charge dry-charged batteries before
use. For maintenance-free batteries for
which water can be added, proper
maintenance by adding necessary
distilled water at due time helps to
extend their service life.
5) Make sure that the air vent in the
battery cover is unblocked. When a
battery is charged, many air bubbles
will be produced. If the air vent is
blocked, the air cannot escape; when
the internal pressure increases to a
certain extent, the battery case will
burst.

voltage of each cell shall be limited to
2.3-2.4V during charging. The
conventional charging method will
consume more water, and the charging
current should be slightly lower (below
5A) for charging. If possible, the
maintenance-free battery can be
charged with charging equipment with
current-voltage characteristics. The
equipment can not only ensure full
charge, but also avoid overcharging
and consuming more water.
3) Scrapping indication: When the
hydrometer of maintenance-free
battery indicates light yellow or red, it
means that the battery is nearly
scrapped, and even if it is recharged, it
will discharge very quickly. Charging at
this time is only an emergency
expedient.
