Charge LED
When the charger is charging the green LED has the following meanings:
- Green LED flashes fast: The charger delivers full charge current (with respect to charge
current adjustment) and is in constant current mode.
- Green LED flashes slowly: The charger is reducing the current and maintaining a
constant voltage.
- Green LED lights continuously: The battery is fully charged.
Recommended charge current setting
When using a Combi with a lead acid battery the following table shows the recommended
maximum charge current compared with the battery capacity.

Attention:
- If a sealed lead-acid battery is overcharged it will result in gassing and drying
out. This may damage the battery.
- Wet batteries (open type) will lose water and need be refilled
- If you are in doubt how your battery should be charged please consult your
battery technical document or your battery distributor.
Temperature compensation (NTC sensor)
When using the external temperature sensor (NTC) the charger will reduce the charge voltage
with respect to the maximum allowed battery voltage at the actual battery temperature.
The temperature sensor shall be mounted at a point on the battery with good thermal contact.
Use the temperature sensor for optimal battery performance when using lead acid batteries.
When using Clayton Power Lithium batteries the temperature sensor is not needed.
