Charging batteries

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

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 50A or 63A circuit breaker (or blocking diode) between the power supply and the battery.
Ensure that the output current of the power supply is below the allowed charging current of the battery.
Use only matched batteries when putting 12V types in series.
The return current to the power supply (battery discharge current) is typ. 18mA when the power supply is switched off (except in case a blocking diode is utilized).
