Eunicell CR2430 5011LC 3V Lithium Coin Cell Batteries (5-Pack) - Long-Lasting Power for Watches, Calculators, Key Fobs & Medical Devices

I use this in the remote for my deck awning. If the battery goes and you don't have a spare, the awning has to be hand cranked. I had to do this twice and do not want to ever have to do it again. This lithium battery lasts a very long time and it is easy to forget that you need a battery. I now have a few spares that will always be there when the one in use dies.I have used few of the batteries (CR1220s) in this set and I am happy to report that they are still functioning. The expiry date is set to be an year from now.. I am not very pleased with that.. Other than that minor quibble I am pleased with this set. The pricing is decent for total of 25 pieces of various battery types with I may never use but it is good to have it in my collection.Rating the product with four stars!These batteries are expensive at the store unless you're lucky enough to find a dollar store that sells them. That being said, I feel like I replace this style of battery regularly in various tools, car key, digital scales, etc. around the house, so having a large supply for such a great price is perfect. They work fine and seem to last as long as other brands.Used in an alarm system sensor, lasted three days before low battery warning, used six batteries, same problem. Replaced with so.e from Walmart, been in use now several weeks, no more trouble.Work great!The shelf life is over in less than three months. Not sure how long they will survive. The price was really low and I needed a lot of them.Works as describedI replaced my key fob with these batteries and it showed low battery the instant I used itI ordered 20 of these and I checked out for more they all showed low battery on the battery tester do not buy
