It takes approximately 90 minutes to fully charge. The biēm’s charge lasts anywhere from an estimated week (for a family of four, using it at every meal) to six weeks (for a single person). The biēm comes with a proprietary, high-density battery pack equivalent to 4 AA batteries. There is an LED located at the bottom of the product, which turns red as the biēm’s batteries start getting low.
The battery can be recharged at least 500 times or 10 years of normal use charging on average once a week before replacement
