Sony CR2032 3V Lithium 2032 Coin Battery, 5 Pack

My strategy is similar to most everyone elses': to find the balance between cost and value in buying anything...mindful of a good return policy. These batteries fit those criteria when I bought them, (but DO check out the Maxell 3V batteries as well). The Sony 2032's work fine and they're a good value.There is a space for a "use-by date" on these batteries but no date (I don't know as Maxell even has a space for the date). But, like just about every battery you have bought or will buy, there are no guarantees. I've unknowingly purchased dead batteries just like everyone else. But, most batteries are reliable, even though battery life-span can vary wildly. And, there's the issue: without digging too far into cyberspace, how do you know the life-span of the battery before you buy it? You really don't unless there's evidence of leakage or deformity. Sometimes the 'use by' dates in the retail world mean something. For me, most often they mean a cheaper price for 'out-of-date' stuff. I've never trusted those dates anyway.

I thrifted a Sony Dream Machine CD Player and needed to replace the battery and came across these. Great price, seller shipped fast, and packaged them securely and safely.

I bought these batteries to replace the dead battery in the key fob to my 2005 Pontiac Sunfire. This is compatible with the key fob for any Pontiac Sunfire between the years 2000 and 2005, and also compatible with many other Pontiac/GM vehicle key fobs as well.The batteries came with an expiration date of 2028, so I'm not worried about them going bad before I can use them. I bet if they're stored in a fridge they could last even longer.If you're not sure whether this battery will work for your car's key fob, I recommend you google your car's make, model, and year with the words "key fob battery" (e.g. pontiac sunfire 2005 key fob battery), which will should return plenty of results telling you the correct battery to use.I've had one of these batteries in my key fob since February (about 6 months ago) and it's still got as good of a range as the first day I put it in.When my car's sitting in the parking lot, I can lock/unlock it from my second story window about 40-50 feet away. This is great if I need to carry a bunch of groceries upstairs and don't want to have to fumble around with my keys while holding a ton of bags. I can just carry everything upstairs then lock my car from inside once I've set the grocery bags down.This five pack is about the same price as getting a single one of these batteries at the local battery/accessory store in my town, so it's definitely worth the wait. I have Prime, so these came in just two days to my doorstep. I can't comment on the shipping time if you order without Prime, though.

At the time I purchased these, CR2032s went for about $1 each when purchased in 5 packs. You can get them for much cheaper but only if you buy in packs of 20 or 50. Lithium cells don't last forever in storage, so unless you have the need for a lot of them, stick with the 5 packs. Don't "stock up and save," as the product description would have it.Other reviewers have mentioned the questionable provenance of this particular item. Mine were sold by uTrusted, made in Indonesia, and come with no "use by" date on the packaging. The words "use by" appear, but there is nothing below. The back of each battery is stamped "22", which I believe indicates a use by date of 2022, but I could be mistaken. I tested one cell at 3.25V with a cheap multimeter, which is within the range reported by other reviewers, and well within the acceptable range for a new cell (all the published data sheets for CR2032 batteries I could find start their discharge curves at 3.0V closed-circuit voltage).So, they seem to be fine batteries, at a reasonable price, and available with free shipping as an add-on item. That's good for four stars, docking one because of the lack of use by date marking on the packaging.

What more can you say, a super value for the money.

Satisfactory longevity and performance.

I bought this set of battery to replace the ones found on my 3D glasses and a small pedometer. So far, I can't really complain. They have been working as expected. The battery indicator for both the glasses and the pedometer show that the battery was full when i put them in. I have barely used the 3D glasses but the have used the pedometer every single day for a month. The battery if not even half full.Consider this set of 5 batteries costed me less that $3 dollars with free shipping I consider it an excellent value for low power equipment. When i went to Walgreens to find a similar battery the price was $6 dollars for ONE Energizer battery. Now, i am sure that one was better but i could buy 10 of these generic brand for the price of one of those. It seems like a pretty good deal. I recommend it.

Me resultó bien buena esta opción
