Review on SURPOWER CR1/3N 3V Lithium Battery 10 Pack - 5-Year Warranty Guaranteed by Jay Elgouhari

Car fob batteries usually last 6 months to a year (or more). These last about 4 months tops. I went through 6 in one year for two key fobs and I only use one fob regularly. They die even if they’re just sitting in your fob for 4 months. I purchased in Sept 2021, and the manufacture date was June 2021. With a 2028 expiration date, they should be definitely still be fresh (it’s Nov 2022). My leather key fob cover is so worn it needs to be replaced now from having to change the batteries so much.
