There was a recent post asking a similar question ........... However I NEED liners that have a separate Battery ... Years ago I got frostbite and ever since my Right hand gets very painful at only 20 F ..... I need these from when I'm using my SnowBlower ... It takes about an hour plus to do my driveway and having to stop to warm my hands lengthens this chore to double ......Thanks , Mike .....AND MERRY CHRISTMAS
