Can I see a battery percentage?Updated 7 days ago
No, and there is a hardware reason for it.
Tracking state of charge takes dedicated circuitry, a fuel gauge, that keeps a running count of what has gone in and out of the battery. For most common battery chemistries, you can buy a chip that does it, and Texas Instruments makes a whole family of them. One does not exist for the unusual high-temperature chemistry a wireless thermometer has to use, and building that capability from scratch is a significant effort.
So instead of a percentage, you get a low battery alert when the voltage drops to a critical level.
How to avoid running out mid-cook
The runtimes are long and predictable, which is what makes the lack of a percentage manageable:
| Mode | 2nd-generation |
| Cooking mode (target temperature set) | up to 90 hr |
| Instant read (no target set) | up to 24 hr |
| Standby, in the charging cradle | up to 40 days |
On the 1st Generation, cooking mode runs up to 42 hr.
A full charge takes about 25 minutes, and even 5 minutes gets you 24 hours of cook time on the 2nd Generation. Topping up before a long cook costs you almost nothing.
For the full picture, including Boosters and the Display, see How long does the battery last? (CPT & Display).
Still have a question?
If you are getting a low battery alert far sooner than the figures above, email [email protected] and tell us which generation you have.
