Charge the battery until it is full, the battery LED is green, and the battery power gauge is filled.
In certain situations, where many measurements are in use plus the recorder, the load on the monitor
may be so high that the batteries will not charge. In this case you must use the 865432 Smart Battery
Conditioner (previously M8043A Smart Battery Conditioner) to charge the battery.
Conditioning a Battery
You must condition a battery when its "battery requires maintenance" symbol shows on the Screen.
Do not interrupt the charge or discharge cycle during conditioning. You can condition a battery in a

It is, however, preferable to use the 865432 Smart Battery Conditioner (previously M8043A) for
external battery conditioning. The Smart Battery Conditioner automatically performs the correct
charge or conditioning process and evaluates the capacity when fully charged. For details please see the
