8. Knowledge About Automobile Battery
8-1 the internal resistance of different types of battery differ
The internal resistance differs because of inconformity of internal
chemical feature even if with the same type battery. It is very small so that we
generallydefine it with unit of milliohm. Internal resistance is a
significanttechnical standard to measure a battery. Normally the battery with
small internal resistance has a great ability to discharge. On the contrary the
battery with large internal resistance has a little ability to discharge.
8-2 it is unavailable to know the electric quantity of storage
battery by guessing
Hydrometer can be used to check the condition of the battery. Battery
water is distilled water and pure sulfuric acid of the proportion of 1.260/20 ℃
to allocate. For a new battery, it is supposed to supply distilled waterwith
reduction of battery water for the reason that the degree of acid is fixed when
the quantity of battery water remain the normal range. Distilled water
supplement can maintain a certain amount of water, but alsothe PH value. If
the battery works normally, in addition to the PH is fixed, the proportion of the
value will be in a certain range.

If the battery finishes charging, the proportion of battery water does not
reach 1.26-1.28, along with the tested voltage under 12.7V, the storage
capacity of this battery has descended. It is impossible to recover its life by
deliberately adjusting the proportion to 1.26 (Increase the sulfuric acid

minutes, then check the battery when it's voltage value drop to the normal
value.
(4) Check the insulating layer of the clamps before measuring. Damage,
bareness and disconnection are unacceptable. It is forbidden to use without
covering the rear cover correctly, which can cause electric shock.
(5) Do not use or store the tester in the condition of high temperature, high
humidity, combustibility, explosion and strong electromagnetic field.
(6) Do not change the internal circuit at will in order to avoid damaging the
tester and keep safe.
(7) Wear proper eye mask when testing or repairing in order to avoid some
objects hitting eyes by the engine.
(8) Make sure ventilation when testing or repairing in order to avoid smelling
some toxic gas.
(9) When the engine is working, do not put the tester or accessories beside
the engine or exhaust pipe in order to avoid damaged by high temperature.
(10) Make sure that repair vehicle under the warnings and attentions in the
right procedure written by the manufacturer.
