Summary: These didn't work at all

Comment: I put them in my smoke detector about a month and a holf after I received them. They didn't work at all.

Summary: Great Batteries

Comment: I ordered these batteries to use in our wireless smoke detectors on the alarm system. We found they work just a well as the more expensive versions in the store. You can get 3 packages here for the price of one name brand and we have not found any difference in quality or usage time.

Summary: Delivery "Just Like FEDEX But Cheaper"

Comment: The batteries arrived in fine condition but they took awhile. I got a call from A-1 Courier apologizing that their driver could not find my suburban Northern Virginia address. I kept asking who the caller represented and she said "A-1 Courier. We're just like FEDEX but cheaper." Well A-1 is not much like FEDEX if they can't find a simple address. For Amazon Prime customers like myself, this is not a welcome move by Amazon to cut costs.

Summary: Good batteries, cheap shipping, backed by Amazon

Comment: These are being sold by Amazon itself now, so no worries about overpriced shipping. Aside from that, there's not much to say about batteries. Nice price and they work. Whoever said they are "Worthless" and don't hold a charge doesn't know what they're talking about - these are not rechargeable batteries.

Summary: Good Price

Comment: Compared to any brand in the market I found this one to be the cheapest. Almost 3x lower!
