Roomba 760 dock charger current

Postby wildjohn » August 10th, 2018, 2:14 am

Hi all

All of a sudden 2 days before the roomba could not be charged on the dock.
After a few attempts to clean the contact points which didn't solve the problem, i got my multimeter and i saw that the current from the cable on the wall that plugs on the dock is 24V while the current on the pins that touch the roomba is 2.3 - 3 V

Are these numbers correct or i should find a new dock?

Those are correct. Search for "charging Jack" here and you'll find the probable cause...

So after a few hours spending on checking the bot with the charger, i came yo the conclusion that all that was needed was a good cleaning on the contacts.
What came up now is that the battery seems to be damaged because all the times i left the bot cleaning i came back home finding it on random spot out of power.

How can i be sure that the battery is faulty?
Any tip on this?
Also is there any upgraded battery (if it needs replacement) with more capacity or better in any way?
