Overridden With Inconsistencies
By Joseph Torrillo
I run the "battery center" at my work (approximately 60 employees). We primarily use AA rechargeable batteries to power keyboards and mice. I have about 200 rechargeable batteries in rotation currently. Between Duracell, Lenmar, Eneloop and the Amazon Basics, the Eneloop have by far been my favorite. I only bought the Amazon Basics because the price was remarkable and figured I'd give them a shot. I use the La Crosse Technology BC-700 Alpha Power Charger. The eneloop batteries stay charged for 4-6 weeks on average and always fully charge to around 2.2-2.4ah. The Duracell are a strong second place. They fully recharge to values higher than the eneloop, but seem to drain faster.
The Amazon Basics have been very inconsistent since buying them. I've bought three of the 16 packs so far. The first pack was "precharged" but 4 were returned to me, drained, after only 4 days. One of those 4 was simply dead. The charger couldn't even recognize there was a battery in the the chamber. Eight more of them were returned to my desk after 2 weeks. One of those 8 only recharged to half spec. The last 4 were returned after 4 weeks and two of those four only recharged to half spec.
When recharging them, I always fully discharge before recharging. The eneloop rarely, if ever, have any issues. The first box of 16 Amazon Basics have just been inconsistent. I'm hesitant to open the other two packs I bought. I might return them and just suck it up and buy the more expensive eneloop. At the pace we are dependent upon and cycle through batteries, it's worth it to have the reliability of the eneloop. Having to go through and discharge and recharge the Amazon Basics two or three times to get them back to operating specs is simply too time consuming. I am giving them a 2-star rating based on the fact that the price is still good even with only 12 working batteries and that they serve as a good backup plan while I'm recharging the eneloop.

These batteries work great for one or two cycles and then quickly degrade to a point where they hold very little charge. The early versions of these batteries were made in Japan and were essentially rebranded Eneloops but that is no longer the case. They are now made in China and are the absolute worst quality rechargeable batteries I have ever used. I believe the vast number of positive reviews were for the early version battery and do not account for the change in manufacturing that has taken place. Unfortunately I bought quite a few and did not catch how bad the quality was until after the warranty had expired. I wanted to share my experience so that others don't fall into the same trap. Best of luck if you decide to take the plunge!

DO NOT BUY
By Rob Boyd Jr.
I purchased these batteries for my son's toys. Most of the reviews on the product were positive, so I felt I was making a good purchase. I was wrong. Immediately after putting the batteries in a couple toys, I noticed that the toys were not fully operational. The toys ran as if they would on weak batteries. Thinking I did something wrong, I let the batteries charge for days. Same result. And to make matters worse, Amazon customer service refused to do anything. I was told that since I was outside the 30 day window that I had to contact the manufacturer directly. In the future, I won't buy anything with Amazon's name on it.
UPDATE: I called Amazon customer service and they authorized the return for the batteries. If you decide to order these batteries, my best advice is to try them quickly to ensure there are no duds in the batch.
