Hi Morten,
I checked your user account and found that your H7600 is almost a year and a half old. Rest assured the lithium batteries used in our devices have a longer life span than this particular one installed in your unit, but unfortunately it would appear that this one needs to be changed. I will need some additional information from you and would like to assist with you acquiring a battery, so I am going to follow up with you off-line. Expect an email from me shortly.
