Surveillance and charge condition
This traditional machine needs supervision during the charge.
When the battery is charged, the electrolyte starts boiling. It is recommended to stop the charging
process at the beginning of this phenomenon to avoid damaging the battery.
Besides, if the battery remains connected to the vehicle, a prolonged charge without supervision may
damage the on board electronics.
The end of the charge can be detected either by the position of the ammeter pointer is in between 0
to 10A or either when the charge time is exceeding 10h.
Sealed batteries
CAUTION! When charging a sealed battery, you must charge slowly, constantly monitoring the voltage
at the battery terminals. It is advisable to stop the charge when the voltage reaches 14.4V for a 12V
battery and 28.8V for a 24V battery. This voltage is measured using a voltage tester.
Charge of several batteries simultaneously
USE IN STARTING MODE (START)
