What kind of voltage should a battery charger put out when you test it at the clips with a volt meter?

at 12v/10 amps I get around 10.5 volts

at 12v/2 amps I get around 9.5 volts

Not on the battery, just hooking the clips to a VM.

Thanks

 

What sort of battery are you charging?

A 12V sealed lead acid battery for example will require something around 13.7V.

 

You may get all kinds of misleading readings without a battery connected, depending on the technology used, the one I built some time ago requires to see a battery voltage/load before you see any reading.
Max.

 

The unloaded readings don't mean anything. Try attaching a lightbulb or attaching to a battery. You should get ~14V

 

Dear Sir/Mam.,
We are using the LTC2941 IC for the Li-ion battery level indication(3.6v) and also use the charging IC(LTC4057)with AT32UC3A3 controller.

Just now i made the hardware connection based on this.

Then i need to connect the LED for the battery level charging and discharging based on percentage.
How can i made the code for the above concept.

Please clarify this as earlier...
