what time last the default battery? and how much is the improve with 3 batteries?, have you consider replace the default battery with a more powerfull lion littium battery?

The default batteries (2)used to last 3-4 hours,but that only lasted about 6 months.It went down to about 60 minutes.I inserted new batteries inside the ups,but decided to add the older two(2) batteries as well.
When the time come I will decide whether to replace it lithium batteries.Another option is to try and "repair" the lead acid batteries.That will be in another video.Whether it will work,I don't know.
