Ok, this is the 2nd time I bought this batteries, the first order was on November 6, 2017 for a 48 pack and they lasted until a month back I was very happy with the batteries, consistent, good value, they lasted long and worked out fine. I use them mostly for RC's, apple mice, led candles and a automatic trashcan.
My second order of 48 came in June 2, 2018. And to my surprise this batteries do not compare with my first order, the ones I put in the trashcan lasted 3 weeks (6/8 weeks before) same with the ones on my apple mouse.
Looks like somewhere in between last year batch or this year there were some quality issues. Or maybe I got a box of lemons.... I'll report back when is time to order again and either add or knock down stars.

Quality alkaline AA batteries at a good price. You know we're always being bombarded by TV and other advertising at how great small batteries can be. I decided that it would be fun to put them to the test. I used a Fluke digital multimeter which I calibrated using a D.C. precision regulated power supply which was checked on a Tektronix scope for accuracy. Out of the box fresh I measured 4 different brands of AA cells first with no load just using the Fluke Multimeter. First the Delcos measured 1.63 volts without a load and 1.54 with a flashlight bulb load. Excellent way above rated specifications. The Duracell and energizer were almost as good measuring 1.53 under load, again very good. The Batteries from BJ's didn't do as well only measuring 1,.4 under load and 1.5 with no load. Conclusion: The AC DElco AA batteries performed as good as the much more expensive Duracell and energizer batteries and are well worth buying. This applies if you use a lot of these guy's for remote controls or other small electric battery powered devices. Well worth the money and highly recommended as indicated by a usage test with accurate equipment.

Do not buy! They leaked in ALL our electronics: a pair of self-stabilizing binoculars - we thought it was the heat exposure - then the TV remote control, where the leakage ate away the leather of our sofa. When we investigated, we found they had leaked into the graphing calculator, the blue-tooth grilling thermometer and every remote we had put them in. Don't risk hundreds of dollars in damage or hours of cleaning and restoring for your valuable electronics. I wouldn't even take them for free.

These batteries only last two days in my Roku remote. It doesn't matter if I use it all day, or not at all during the day, the batteries are dead after two days. I've even changed the Roku system to another one,.same thing happens.

Based on other reviews I bought these batteries and find that they discharge in an Xbox controller more rapidly than the energizer batteries we had been using previously.
