I only get short or no charge in batteries
I have 6 batteries - yellow & black. The green light keeps blinking on all but 2 of the batteries.
The 2 batteries with a solid green light only charge for about ten minutes. And they only last a few minutes in the Roomba.
How do I figure out which batter IRS are dead AND is there a way to get at least the two batteries to take a longer charge?
Is this a good question?
