Charging batteries

The power supply can be used to charge lead-acid batteries or maintenance-free batteries (SLA or VRLA batteries). Two 12V batteries connected in series are required.

Instructions for charging batteries:

Set the output voltage (measured at no load and at the end of the battery cable) very precisely to the end-of-charge voltage.

End-of-charge voltage	27.8V	27.5V	27.15V	26.8V
Battery temperature	10°C	20°C	30°C	40°C

Use a 15A or 16A circuit breaker (or a decoupling diode) between the power supply and the battery.
Make sure that the output current of the power supply is below the permissible charging current of the battery.
Only use matching batteries when connecting 12V types in series.
Make sure that the ambient temperature of the power supply remains below 40°C.
The reverse current to the power supply (battery discharge current) is typically 3.5mA when the power supply is switched off (except when using a decoupling diode).
