Review on High-Performance NABC UltraLast ULA100AAB AA Size Alkaline Batteries (100 Count) by Erica Jackson

After reading all the reviews on these batteries and realizing that they are pretty bad, I decided to follow in another reviewer's footsteps and do some testing. I ordered a pack of 100 Ultralast AA alkaline batteries and found the best deal I could find on name brand batteries. I ended up finding 36 packs of Energizer AA at Home Depot for $14, which is 42 cents each after tax. These Ultralasts cost 23 cents each after free shipping and excluding taxes. As soon as they arrived, I pulled out my trusty multimeter and headed into town. I tested 10 energizers (28% of the pack) and all showed 1.61 volts right out of the box. Ultrafins are packed in 10 shrink-wrapped packs of 10. So I stuck the sharp ends of the multimeter leads through the plastic shrink wrap to test 4 out of each pack of 10 (40% of the total pack). I did this so I can return them if they turn out to be low with less chance of acceptance issues. Of the 40 batteries I tested, most measured 1.62 volts and a few measured 1.63 volts; Better than energizers! I don't have the ability to test milliamp hours (mAh) so I can't say if the total capacity is the same, but from the readings I've taken for alkaline batteries the consensus seems to be that the battery type will have almost the same capacity, regardless of manufacturer. (I googled "all alkaline batteries are the same" and read some of the articles/blogs/etc I got.) Obviously an alkaline battery has a higher capacity than a carbon battery and a lithium ion battery has a higher capacity than one alkaline, but there's only so many mAh that any manufacturer can cram into a single AA battery. Looks like some buyers got a bad batch but I think they're worth ordering. Test a few and if you get a bad batch, return them.
