KBT KEEP BETTER TECH RAMWAY ER14250 3.6V Lithium Battery 1/2 AA Size LS14250, 1200mAh High Capacity, Li-SOCL₂ Lithium Batteries for Water Meter Electricity Gas Meter

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. 👍

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.

Does the job. Good price. Came quick.

When I received these batteries, the expiry date had already been reached.Update:When I sent in a picture to the seller, they said that the date on the battery was the date the battery was manufactured, not an expiry date. Seems strange because all other battery manufacturers stamp the expiry date on them. I don't feel comfortable using these batteries in my water sensors so will test 1 in a sensor that has a backup and replace the others with different batteries.Having said all that, the manufacturer did offer to replace or refund.

These batteries are bigger in diameter than the industry specified diameter. Industry standards specify a diameter of 14.1mm, +/- 0.2mm. In essence, they cannot be any wider than 14.3mm. Every one of these batteries measured 14.8mm in diameter, and so did not fit appropriately. I tried them in three different units and they did not fit in any of them, so they were returned.
