The ECoS does not contain any circuitry for re-charging batteries. Use alkaline batteries or re-chargeable batteries charged with an external charger.
The ECoS 2 does recharge the batteries. Don't use alkaline batteries. Only use suitable re-chargeable batteries (NiMh or NiCD).
4 LR3/AAA size NiMh batteries are supplied (black batteries below).
Personally, I like the Duracell batteries as they are very reliable (there is one in the photo above). I'll use 4 of these in the ECoS.
Translated from the German manual:
Insert the batteries
We recommend that your ECoS always used with a charged set of batteries. This is to ensure that in the case a power failure, the ECoS has enough time to properly save all data settings and then shut down properly.
This "Emergency power supply" is to cover any interruption of power which could otherwise lead to a loss of data.
When the ECoS is switched of, the batteries can be removed as the data is stored in Flash memory.
During normal operation, the batteries are automatically recharged.
If the ECoS is unused for extended periods, the re-chargeable batteries could discharge. In this situation, the ECoS should be left on for at least 4 hours to fully recharge the batteries.
The battery compartment is located on the underside of the ECoS.
• Remove the battery cover by pressing the clip in the direction of arrow.
• Insert the four batteries. Make sure of the correct polarity. The polarity ( "+" and "-") is printed in the battery compartment.
• Replace the battery cover.
• Use only high quality re-chargeable batteries. The contact surface of the negative pole of the battery must protrude through the casing of the battery!
• Remove the batteries from the ECoS only when switched off and unplugged from the mains.
• Remove batteries if the ECoS will be stored for an extended period (e.g. when you go on holiday) to avoid any leakage.
• Never attempt to use normal alkaline batteries in the ECoS! The charging circuitry cannot detect alkaline batteries. Inserting the wrong type of battery will lead to damage and may cause fire or explosion!
