## Product: Braun Series 9 Pro Shaver
**Brand:** Braun

For the Braun Series 9 Pro 9420s, you'll want to replace the shaving head roughly every 18 months. This recommendation comes from the manufacturer to help keep your shaver working at its best. They suggest that after 18 months, the cutting elements, including the ProLift trimmer, can start to lose their sharpness, which might affect your shave quality.

Why the 18-month mark? With regular use, the blades will naturally get dull and the cutting elements can wear down. By swapping out the shaving head as suggested, you’ll keep your shaver’s performance top-notch and enjoy a close, comfy shave every time.

As for the battery, the Braun Series 9 Pro 9420s uses a lithium-ion battery designed to last and hold a charge for up to 6 weeks. The manufacturer doesn’t expect you’ll need to replace it often, but if you notice it's not holding charge as well after a while, a new battery might be necessary.

So, to keep your shaver in great shape, plan on changing the shaving head about every 18 months and just keep an eye on the battery’s performance. 

Regular maintenance will go a long way in maintaining the quality and reliability of your Braun Series 9 Pro 9420s.
