Product 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 maintain 85 percent of their charge after one year and can be recharged up to 1,000 times. This new technology offers consumers the convenience of a ready-to-use rechargeable battery that is longer lasting and environmentally friendly.

Customer Reviews

Finally! Good rechargeable batteries.
For many years, rechargeable batteries (AAA, AA, C, D) have been very disappointing because they "self-discharge" in a week or two while waiting to be used (or sitting on a store shelf). That's why you must always charge new batteries before using them.

These new Sony batteries finally solve the problem. They self-discharge very slowly, keeping 90% of their charge after a year of storage. I have been using several AAA and AA Sony rechargeable batteries for a month now, and am very pleased and impressed. I only wish that C and D cells were available.

Little batteries, Big power
I use these batteries in my digital camera. Got them not long ago, it works a long time in the camera. Longer than my old 900m ones. I use the old 900m ones in my remotes now, those doesn't require as much power usage.

Switched to all rechargeable batteries to be more eco-friendly. Many people still buy the batteries at $0.99 store which lasts very short time and end up as hazard trash. I hope the manufactures can ship the products such as remotes with the rechargeable batteries to promote it.

Sony battries
I ordered this style of battery to see if it was better then the other Sony rechargable batteries. I did know that know rechargabke wouldnt work in my TV remote. I was surprised, other than that the appear to last longer than the other Sony battery.
