Battery life by temperature. At a continuous 80°C, expect ~2 hours of heating per full charge. At 30–70°C, expect 4+ hours depending on the exact setting.
Not sealed — by design. WarmByte isn't fully leak-proof on purpose: a sealed container under heat would build pressure and risk damage. This keeps daily heating safe and reliable.
