ATTENTION!
•
If sealed lead acid batteries are overcharged it will result in gassing and dry-out and the battery will
be destroyed.
•
Wet batteries (open type) will loose water and need to be topping up.
•
If you are in doubt how your battery / batteries shall be charged please consult your Battery
Technical Manual (data sheet), or your local battery distributor.
Temperature compensation (NTC sensor)
• When using the external temperature sensor (NTC) the charger will reduce the charge current with respect
the max allowed battery voltage at the actual temperature!
• Refer to scheme: at 20°C the boost charge max voltage is 14,4V and float charge voltage 13,5V
• Use the NTC temperature sensor for optimal battery performance.
