Review: Good value - Since I leave my garage door open for longer time than most, it takes a toll on the batter life I purchased these to ensure that I have a replacements ready. 👍
Review: Dates - As other reviewers have already stated, the batteries I received this week have a 8/31/2023 date on them. The seller says that’s not the expiration date and insists that it’s the manufacture date. They seem to work, not sure how long they will last. I will update. Not worth returning.
