To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The pack of 4 itself came a little damaged but the batteries were all good. Give it a 4 star because I used 1 battery on my guitar and it seemed as if the battery was at the end of its life. It lasted less than 4 days. But I put another one in and the battery seems good, it's been on my guitar quite a while now. Overall it's a good purchase
I would give this five stars except the date of manufacture isn't shown. It's good to know the batteries are good for "Five Years in storage" but from what date? The date of manufacture? The date of purchase?
Let's face it, Duracell has successfully branded themselves as the best battery around. And the truth is, I get the best results with them over any other. They last long, and can keep sustained power for a host of electronics, from cutting edge to the cheapest toy. Any time I use a bargain brand to save money, I'm quickly reminded that I'm not really saving much, since they die so fast. So I keep a supply of cheapo batteries on hand for things that don't matter and don't drain a lot of juice. Duracells, I save for the important stuff, flashlights, radios, emergency essentials. What good is saving a few cents if I'm left in a pinch during an emergency? With all the little gadgets I got squawking for juice, I just wish these Duracells cost a little less. But every once in a while, Amazon has a digital coupon available, and that, coupled with Subscribe & Save, does help. Other than Duracell, AmazonBasics makes a great battery; but only in AA and AAA. No 9v that I know of.
Bottom Line -- do you really want to trust something important, like a fire detector, to a cheapo battery? I don't. That's why I got these.
Never really had any problems with Duracell batteries. the brand seems to be reliable and durable. Cost/value is a matter of perspective, I think all batteries cost too much, so hard to rank that. But overall good quality and reliable, so not sure what else you can ask for
I am a long time Duracell purchaser but for some reason the last two packages of 9 volts had batteries that died very quickly in my CO2 and smoke filters. Unusual for the brand in my experience so I am chalking it up as a anomaly.
My Smoke Alarm manufacturer recommends only these batteries for replacement, but they are nearly 2X the price of other brands. I paid the premium since it's a once a year purchase, but it's tempting to go with another brand. But other than the cost, these seem fine and are working.
