WARNING
Do not charge a battery quickly.
CAUTION:
Do not use a battery charger charging
fast, as it forces a high amperage
the battery quickly and can cause
overheating and damage to the plates
battery.
If it is impossible to regulate the load current
in the battery charger, be careful
not to overload the battery.
When charging a battery, make sure
remove the vehicle. (If the load, mounted
in the vehicle, disconnect the negative cable
terminal of the battery.)
To reduce the risk of sparks, do not connect
the battery charger until the cables
battery charger connected
to the battery.
Before removing the charger cables
batteries, battery terminals,
sure to turn off the battery charger.
Make sure the charger cables
batteries are properly connected to the terminal
battery and are not shorted.
A charger with corroded wires can
generate heat in the contact area and a
weak caliper can cause arcing.
If the battery becomes hot to the touch, in any
time during the charging process,
disconnect the battery charger and let
the battery to cool before re-
connecting. A warm battery can
explode!
A. Open circuit voltage (V)
B. Time (minutes)
C. Load
D. Temperature 20 ° C (68 ° F)
E. Check the open circuit voltage.
ELECTRICAL COMPONENTS
Charging method with a charger
current (voltage) variable
a. Measuring open circuit voltage before
to loading.
NOTE:
The voltage must be measured after 30 minutes
without using the battery.
b. Connect a charger and an ammeter to
battery and start charging.
c. Make sure the power is higher
than the standard load current
written in the battery.
NOTE:
If the load current is less than the charge level
written in the battery, the voltage adjustment of the load
20-24 V and track the amperage during
3-5 minutes to check the battery.
• If the load current standard was achieved
by the battery is good.
• If the load current standard was not achieved
by the battery replace the battery.
d. Adjust the voltage level so that it reaches the
normal load.
e. Set the time, according to the time
the proper charge voltage for open circuit.
f. If the load requires more than 5 hours, it is advisable
controlling the charge current after 5 hours.
If there is any change in amperage, re-
adjust the voltage until the charge level
standard.
g. Measuring the charging voltage in open circuit
the battery, after having been out of use
over 30 minutes.
12.8 V or more --- Charging complete.
12.7 V or less --- Recharging is required.
Under 12.0 V --- Replace the battery.
