Description |
| Sony's newest rechargeable battery technology seeks to bridge the gap between regular alkaline batteries and NiMH rechargeable batteries. Cycle Energy rechargeable batteries do not require initial charging and have a very low self discharge rate. They preserve 85 percent of their charge afterwards one year and can be recharged up to 1,000 times. This new technology proposes consumers the convenience of a ready-to-use rechargeable battery this is longer lasting and environmentally friendly. |

 They work 2010-06-25 |

| What more can I say? I'm no guru with these things and I'm not using them on any sensitive "voltage" items. They're great for my wireless fight stick and old school mp3 cd player. |
 Varying capacities with these Sony's 2010-06-03 |
| By MikeP (Boston, MA) |
I bought two sets of AA and one AAA of these Sony Cycle Energy batteries from a large NY-based and internet camera store during an 8 USD/AA 4-pack deal was posted on slickdeals a couple of weeks ago and I wanted to relay my experience. (Though I do buy most everything else at Amazon!)
All of the batteries were made in China as per prior posts. They all came out of the package with decent voltage (1.3v? I don't recall exactly) but at maybe 50% of the rated charge of 2000 mAH. I personally don't much care since I was going to charge before using anyway. I had encountered a significant variation with 4 of the 8 AA batteries -- 3 from one pack and one from the other pack.
I use the La Crosse BC-700. I did a simple charge of all of the batteries first. That did not bring the charge up near the rated level. On the first 4, I did a single full discharge-charge cycle and they went up as high as almost 2400mAH! Great! The other 4 did not fare as well. A discharge-charge cycle still did not get them up to 2000 mAH, though mostly in the ballpark. I then did a full "refresh" (repeating discharge/charge cycles until no improvement) and 2 made it to 2030 mAH, while the other 2 only 1970mAH.
SUMMARY:
With discharges and refreshes, all of the brand new Sony's were able to get within an acceptable tolerance +/- of the rated charge and some went far beyond the rating. My main point being that not all of these Sony's are created equal. I'm still using a set of Eneloops for my SLR flash, but these are just fine for wireless mice, WiiMotes, toys, and the like.

| A great improve over the normal rechargeable batteries 2010-02-17 |
| By Will Vasquez (San José, Costa Rica) |
I was used to have the batteries that came with the charger, those batteries would last around one week charged after a full charge, this ones instead come with a full charge, and it doesn't go away after a month without using them.

| Some of the best rechargeable batteries that I own. Make sure you have a good charger to accompany them if you want the most bang for your buck. |
