The faucet comes with a battery pack of 4xAA alkaline batteries. When the indicator light on the spout shows low battery, simply replace the batteries. As it's a non - returnable item, make sure to check it thoroughly upon arrival. For maintenance, clean the faucet regularly with a soft cloth and mild cleaner.
