Battery-operated bath toys are generally safe for water use because the voltage in batteries is so low, according to "It's a Wired World," a teacher's guide to teaching kids about electricity. According to ToddlerEducationalToys.com, an independent website that reviews toys for toddlers, the following care should be taken with battery-operated bath toys: "Check the seal of the storage section. You want to make sure that it is definitely watertight, as water leaking in will reduce the battery life and ultimately destroy the toy."

On the Other: Monitor Toys for Basic Safety

Some components of battery-operated bath toys could pose a hazard. The CPSC recommends checking the components of any toy to ensure that they are not small enough to present a choking hazard. Products containing strings or nets should be closely monitored, as they can present a strangulation hazard.

Bottom Line

Battery-operated bath toys are not inherently hazardous to children; however, take the same safety precautions when using these toys that you would take with any other toy and also make sure the battery compartment is watertight to avoid damage to the toy.
