Replacement Batteries Braun, Norelco, and Remington Shavers do not have user serviceable batteries. To replace the batteries, you must contact the manufacturer directly and send the shaver back to the manufacturer at your expense to have a technician service the shaver. By the time you add parts, labor, and postage, it can almost be the same cost as buying a replacement shaver. A less expensive can be to buy a Factory Refurbished shaver.
