Rechargeable Meat and Food Thermometers

They avoid routine disposable-cell replacement, but they must be charged and their internal battery may age. A replaceable-battery model can be more practical for infrequent use or very long storage.

Only if the manufacturer explicitly supports that use. Charging near heat, water, or raw food can create avoidable safety and hygiene problems.

Clean and dry it as directed, protect the probe, and store it away from high heat. Follow the maker's battery guidance if it will not be used for a long period.

No. Water resistance is a separate manufacturer rating, and charging ports or cases may have different protection from the probe or handle.
