There may be a problem with the charging base.
solution
Call the customer service of Philips to ask, need to be repaired and sent to repair.
Toothbrush charging method
Pay attention to the type of rechargeable battery your toothbrush uses, is nickel-metal hydride or lithium ion, although the current electric toothbrushes say they can be placed on the wireless charging base for a long time, but nickel-metal hydride batteries still have a memory effect that can not be ignored, please charge in the correct way. Of course, high-end lithium-ion batteries do not matter, with charge.
Toothbrush head replacement
Electric toothbrushes have the same life span as regular toothbrushes, about 3 months, or follow the toothbrush's smart prompts to replace. For your health, please buy genuine brush heads.
Philips battery is not durable, 2 years can not be done, I now use a Miller sonic toothbrush very good, has been used for more than 2 years, and still very good!
