Batteria zaino Stihl AR3000L COSÌ COM'È

It's not working. Case in good shape. When the button is pushed, all green lights come on. Will not charge. The case has not been opened, so I don't know if it's just a wire or a bad cell. They are repairable. Received this with a bunch of other items. Sold as is for parts. No returns as it is for parts.
