Lead acid batteries are the oldest and most among
the all-battery technologies. Because of their
large applications, lead-acid batteries have the
lowest cost of all-battery technologies. This
battery operates at an ambient temperature and
has an aqueous electrolyte. Even though the
lead-acid battery is relatively inexpensive, it
is very heavy, with a limited usable energy by
weight. The average life of a lead acid battery
is two to four years, depending upon its quality
and the kind of care exercised in its use. To get
maximum life out of a lead-acid battery, the
following procedures are recommended.
3
Keep the Top of Battery Clean Dry It is
important to keep the top of the battery clean
and dry at all times to prevent corrosion and
leakage of current. If corrosion has started, the
battery may be cleaned by the use of a stiff
brush and then wiped with a rag moistened in a
solution of household ammonia.
4
Keep the Electrolyte at the Proper Level The
level of electrolyte should be checked at regular
intervals of one or two weeks and when found to
be too low it should be brought to the proper
level by adding water free from impurities. It
should always be 1 Cm above the top of plates and
separators.
5
Take Frequent Hydrometer Readings It is advised
to take these readings at the same time the level
of electrolyte is being checked. When the
specific gravity of the electrolyte drops to
about 1.18, the battery should be recharged. Low
charged battery produce excess of lead sulphate
on the plate reducing life of the battery.
6
Never Over Charge the Battery Over charging may
cause excessive heat and gassing and also a
permanent loss in some of the active material of
the plates. The battery temperature should not
exceed 40 degree Celsius.
7
Dont Leave Battery Discharged For a Long
Period Battery in a discharged condition for a
long period may form a coating of hard lead
sulphate on the plates. This sulphate coating
cannot be converted to active materials and the
battery is permanently damaged.
8
Give a Fresh Charge If a lead acid battery is to
be stored for several months, the level of the
electrolyte should be periodically checked. After
intervals of 4-6 weeks, the battery should be
given a freshening charge so that it will be kept
fully charged at all times.
9
Never Short Circuit the Battery Since the
internal resistance of a lead acid battery is
very small, a short circuit will give a damaging
current of several hundred amperes. This may
cause the plates to buckle ruining the battery.

• Warning
• If battery electrolyte is spilled, take immediate
  action to stop its corrosive effects.
• External Flush with cold water to
• remove all acid.
• Eyes Flush with cold water for 15 minutes.
• Get medical attention at once.
• Internal Drink large amount of water or milk.
  Follow with magnesia, beaten egg or vegetable
  oil.
• Clothing or Vehicle Neutralize with baking soda
  or household ammonia solution.
