STARTING AND CHARGING - BATTERY 20-11

BASIC INSPECTION

1 . Appearance inspection
(a) Observe whether the battery appearance is in good condition. Check if fixed terminal
and wires are connected firmly.
(b) Observe whether the battery shell and the center partition cracks, and use a wooded
stick to beat shell and center partitions respectively. Breaking sound is not heard.
Especially the central baffle and shell side of shell wall at the junction of four, prone
to crack, should be carefully examined.
(c) Through mirrors, blue shows good battery state, yellow and red indicate lack of
electricity and no electricity. The following capacity, specific gravity and voltage
inspection should be done.
2 . Capacity test.

(a) The excel tester is also known as the
discharging tongs. It consists of a DC
voltmeter and one load resistance. 20
(b) The tips of the two tongs shall be pressed on
the anode and the cathode tightly and sustain
for five seconds in the measurement. Observe
the terminal voltage in the state of the big load
discharging and the discharging content and
the starting ability can be judged correctly.
(c) For the excel tester of different brands, the
readings of the current and the voltage shall
be read according to the regulations of the
factory manual. Generally, the single voltage
of the battery in good state should be above
1.5V and keep steady within five seconds. If
the voltage drops rapidly within five seconds
or the voltage of one single cell is 0.1V lower
than that of others, it indicates there are
troubles in the battery and it should be
repaired.

Below is the use of excel tester of discharge plan detection income cross-references.
