Bought Accutire pressure gauge in July 2016. Manufacture date on the gauge said May 2006, with 10 year warrantee, so 10+ year old product out of warrantee at date of sale, which is why they probably included a cheap replacement battery. But manufacturers warrantee states that attempting to replace the battery on your own voids warrantee. I have jewlers' tools (couldn't replace the battery without them), and skills, so replaced battery with a fresh Sony battery anyway. Gauge refuses to read anything except 00.0. Double DOA!
