The 2- 1.5 AH 48-11-1815 batteries do power on and charge on the charger but are in very used condition. They have major scuffs and wear. The other two batteries (2.0 AH 48-11-1820 & XC 5.0 48-11-1850) will not power on and give an error code on charger. They look to be in lightly used condition. Selling all 4 batteries as a lot. See images for item condition.
