If a Duracell battery leaks, it is important to handle the situation with care to ensure safety. First, you should carefully remove the leaking battery from the device it was in. Be cautious and avoid contact with your skin, as the leaked material can be corrosive. After removing the battery, it is advisable to wear gloves when handling it.
Next, you should clean the area where the battery was stored, as well as the contacts inside the device. You may use a cloth dampened with a mild vinegar solution to neutralize any alkaline spill, followed by wiping with water and drying the area thoroughly. Dispose of the leaking battery in accordance with local regulations regarding hazardous waste.
To prevent future leaks, store batteries in a cool, dry place and replace them regularly if they are not in use. For further information on battery care and maintenance, users may find helpful resources on the current Duracell website.
