The batteries should last longer
The batteries should last longer than 2 years. They are only warranted for 1 year (basically one winter season )

Hi, this is the Mobile Warming by Fieldsheer team, we are sorry to hear about your battery issue, we will try to reach out to you directly to resolve your issue. Lithium-Ion batteries will last for many years beyond 2, they do need to be stored with some charge if not used for several months. If stored uncharged for a long duration, like the off season, their lifespan could be reduced. We publish information about battery maintenance on our website and send out notices to our email subscriber base at end-of-season. We offer a 1 year battery on garments and batteries, this is very competitive warranty in our industry and once a product gets past the 1st most likely to continue without issue for many years beyond, but issues do happen so we want to take care of your issue on us.
