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.
For a limited number of shavers we do offer complete replacement shaver handles with new batteries. You can see these items below. We also offer a limited number of factory refurbished shavers that can be a less expensive option than a new shaver.
