Can I use rechargeable batteries?

The Hatch Baby Smart Changing Pad is designed to work best with good quality Alkaline batteries which will last for several months before needing to be replaced, depending on how often you use your Pad each day. Although rechargeable batteries can be used, they may need to be replaced more frequently and may stop features like the low battery indicator from working correctly. Remember never to mix different types of batteries or mix fresh and old batteries.
