•
The charging must take place in an area that is
well ventilated and capable of removing the hydro-
gen gas that is generated by the charging pro-
cess. A minimum of five air exchanges per hour
is recommended.
•
The charging connector components are in good
condition and free from dirt or debris.
•
The charger connector is fully inserted into the
vehicle receptacle.
•
The charger connector/cord set is protected from
damage and is located in an area to prevent injury
that may result from personnel running over or
tripping over the cord set.
•
The charger is automatically turned off during the
connect/disconnect cycle and therefore no electri-
cal arc is generated at the DC plug/receptacle
contacts.
In some portable chargers, there will be a rattle
present in the body of the charger DC plug.
This rattle is caused by an internal magnet contained within the
charger plug. The magnet is part of the interlock system that
prevents the vehicle from being driven when the charger plug is
inserted in the vehicle charging receptacle.

AC Voltage
Battery charger output is directly related to the input volt-
age. If multiple vehicles are receiving an incomplete
charge in a normally adequate time period, low AC volt-
age could be the cause and the power company should
be consulted.
TROUBLESHOOTING
In general, troubleshooting will be done for two distinct
reasons. First, a battery that performs poorly and is out-
side of the manufacturers specification should be identi-
fied in order to replace it under the terms of the
manufacturer's warranty. Different manufacturers have
different requirements. Consult the battery manufacturer
or a manufacturer representative for specific require-
ments.
The second reason is to determine why a particular vehi-
cle does not perform adequately. Performance problems
may result in a vehicle that runs slowly or in a vehicle that
is unable to operate for the time required.
A new battery must mature before it will develop its max-
imum capacity. Maturing may take up to 100 charge/dis-
charge cycles. After the maturing phase, the older a
battery gets, the lower the capacity. The only way to
determine the capacity of a battery is to perform a load
test using a discharge machine following manufacturer's
recommendations.
A cost effective way to identify a poorly performing bat-
tery is to use a hydrometer to identify a battery in a set
with a lower than normal specific gravity. Once the partic-
ular cell or cells that are the problem are identified, the
suspect battery can be removed and replaced. At this
point there is nothing that can be done to salvage the
battery; however, the individual battery should be
replaced with a good battery of the same brand, type and
approximate age.
Hydrometer
A hydrometer (P/N 50900-G1) is used to test the state of
charge of a battery cell (Ref Fig. 30 on page 24). This is
performed by measuring the density of the electrolyte,
which is accomplished by measuring the specific gravity
of the electrolyte. The greater the concentration of sulfu-
ric acid, the more dense the electrolyte becomes. The
higher the density, the higher the state of charge.
