NiMh AA 1650 mAh 1.2V rechargeable battery. Search Amazon.com for philips norelco qt4022 battery. One result is UPC 737212062822

I think you can simply use a AA battery, 1.2V

Note: AA Alkaline battery is 1.5V and not rechargeable.

HI Darren,

I’ve to say this is a cool work. You’ve done an extra-ordinary support for Philiphs Norelco users. As a beard style lover I’s thinking of buying a new Philips one instead of my old remington MB320C. I have already visited online websites like https://trendyseekers.com/best-beard-tri... to learn different model - Panasonic ER -GB 40s, Bruan BT 5070 and more. I have also seen philips norelco beard trimmer 3100. online. But I was curious about blade replacement and battery durability, charge capacity and of course battery replacement. My pleasure I found your post link on the fist page of google; simply hit on and discover your brilliant post. The 3 lines introduction has made a long expression to understand I do think. All the 11 steps you mentioned with nice images really amazing and useful for the users. I would love to say thanks for your awesome work and will be highly appreciated if you let me know how long does the charge remain after a single charging please.

The battery I took out of my QT4000 is EXACTLY the size of a TRIPLE A (AAA) battery - a bit shorter than a AA and much smaller diameter.
