Recovery function
6
• This function is intended for regenerating deeply discharged batteries. It cannot be selected directly. If a deeply
discharged battery is connected to the charger, recovery function starts first. A low charging current is used to bring
the deeply discharged battery back to normal battery voltage. Once the battery reaches its normal voltage, the
charger proceeds with normal charging.
c) Charging time
• The time it takes to reach the charging end voltage depends on several parameters, such as e.g.
- The capacity (Ah) (the greater the capacity, the longer the charging time)
- The type of battery
- The charge status of the battery (full, half-full or empty)
- The ambient temperature (this should ideally be 20 - 25 °C)
- The general condition (age) of the battery
The charging time is based on the aforementioned parameters and can be roughly calculated using the following for-
mula (for a rough time estimation): Charging time (in hours) = the battery capacity (in Ah) x 1.2/charging current (in A)
Example: Lead-gel battery 20 Ah, empty
1
Charging time approx. 5 h. = 20 Ah x 1.2/5 A
d) Charger protective functions
Spark-resistant short circuit and reverse polarity protection
1
• These functions protect the charger from damage if the battery cables are accidentally swapped.

Overvoltage protection

2
• This function protects sensitive electronic components in the charger from damage caused by high-voltage spikes.
Limitation of charging current
3
• This function prevents overheating and damage caused by short or excessive loads.
Automatic overheating protection
4
• Overheating protection prevents damage to the charger due to abnormal ambient temperatures or component
failure.
Please note that the in-built heat protection in the charger constantly monitors the operating temperature
of the electronics. If the operating temperature exceeds the pre-set safety limit, the current is reduced in
order to prevent overheating. This reduces the output current to avoid further temperature increases until
the temperature has dropped sufficiently for safe, full performance.
