USE IN CHARGING MODE
Precautions before use
• Choose a sufficiently ventilated area
• Remove the caps on the battery (if any) and make sure the water level (electrolyte) is sufficient. Otherwise add
deionized water and carefully clean the battery terminals.
• Check that the battery capacity in amps/hour and voltage in volts are compatible with your charger.
Monitoring and state of charge
CAUTION: Charging batteries require monitoring and the charge will only stop when the operator switches the Neostart
to "OFF" or disconnects the device from the mains.
When the battery is charged, the liquid (electrolyte) in the battery starts to "boil". It is recommended to stop the charge
at the beginning of this phenomenon to avoid damaging the battery.
Moreover if the battery is connected to a vehicle, a prolonged load unsupervised can damage the vehicle electronics. As
well as sulphated battery refusing the load will cause the same risks directly from connecting the charger to the battery.
The end of the load is detected by the needle position of the ammeter when it is between 0 and 10A or by a time greater
than 10H load.
Sealed battery
To charge a sealed battery, it is necessary to be extremely careful. The charge must be applied slowly whilst constantly
monitoring the battery voltage. It is recommended to stop the charge when the voltage reaches 14.4V for a 12V battery
and 28.8V for a 24V battery. This voltage can be measured using a voltmeter or battery tester.
Charge
Once the charger is connected to the battery as recommended (see connection and disconnection),
For the NEOSTART 320 :
- Turn the switch to the CHARGE or BOOST 1 position according to the battery capacity.
Warning : In Boost 1 mode thermal protection might be activated at the beginning of the charge if the battery is deeply
discharged.
Neostart 320
For the NEOSTART 420 and 620 :
- Turn the switch to the CHARGE 1 or CHARGE 2 position according to the battery capacity.
Neostart 420
Neostart 620
After use follow the recommended instructions for disconnection.
Charging multiple batteries simultaneously
You can charge multiple batteries simultaneously connecting them in parallel. Connect the positive terminals to the red
clamp and the negative terminals to the black clamp. These batteries or group of batteries must all be the same voltage,
12 or 24V.
Charging in series is not recommended.
