BCB parts are under manufacturers individual warranties, though BCB does get some cooperative warranty support to match the 2 year warranty on your Bass Cat. The registration date is what matters and we would contact BCB Service and verify the registration date, and that you have transferred warranty if you are a second owner. Then you will have a direction to look at and last you can contact the manufacturer of the charger and appeal there if you are looking for help. Though it depends on the brand what you will hear.
