“Will these batteries fit a panasonic KX-TGA680 cordless phone set? The current batteries are Panasonic Ni-MH rechargeable battery BK-40AAABU 1.2v Min 400 major size AAA? And appear to be the original batteries. Thanks!”

• Yes, Panasonic website confirms these batteries will work on your phone. 1.2 volts with 750mAh. Battery life is almost double your current battery. Will take a little longer to charge, but it will charge. Model:HHR-4DPA/4B
