How to change the battery in an Ember Mug
Ember’s (ember.com) original 10oz. mug is awesome! When I first got it it kept my drink hot for so long.
Now, a few years later, the battery dies after just 10–20 minutes. Unfortunately, the company does not offer a battery replacement service for the built-in rechargeable battery.
Has anyone successfully replaced the battery in an Ember mug? How did you do it? Where did you get a replacement from?
