Hi @chura,
 
If the main battery is not new and hasn’t been charged or recharged for a few months you may have to replace the main battery as it may have become depleted beyond recovery.
 
The same with the backup battery
 
Have you actually tested the backup battery with a Voltmeter to make sure that it is OK?
 
Here’s a link to the ifixit [guide|4946]https://www.ifixit.com/Guide/HP+iPAQ+h4155+Backup+Battery+Replacement/4946 guide which may be of some help (not your exact model I know but may be close enough)
