Can I replace the built-in battery with any type of rechargeable battery available on the market?
No, definitely not. You should on no account replace the built-in rechargeable battery with any type of rechargeable battery you can buy in the shops.
- The built-in battery is tailor-made for the charging system in this shaver. Do not try to replace the battery yourself.
- If you have problems with the battery in your shaver, take the shaver to a local Philips dealer, or call the Philips Customer Care Center.
