Overridden With Inconsistencies
on October 9, 2013
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.
