These battery cells are ideal for products like digital camera (DSLR) flash units, remote control toys, and tactical flashlights. |
eneloop batteries utilize a highly-durable super lattice alloy which prolongs the life of this important material. Improvements to this super-lattice alloy have increased hydrogen stability resulting in reduced self-discharge and long lasting, stable voltage output. |
eneloop’s unique 'Clean Energy Loop' initiative is a reality. All eneloop and eneloop pro batteries are pre-charged at the factory in Japan using power generated from solar energy.*** This process is certified twice a year by The Green Energy Certification Center. |
Keep your tactical flashlights, walkie-talkie radios, battery powered lanterns, cameras and other devices powered in the winter. eneloop and eneloop pro batteries deliver exceptional performance at extreme low temperatures, down to –4 degree Fahrenheit.**** |

The eneloop Pro follows the long-standing eneloop tradition of NiMH batteries that run circles around most of the competition. This eneloop Pro battery is NOT designed for general usage, but rather high-drain applications. When paired with these high-drain applications, the Pro excels in a fashion that few other batteries can, giving you performance that other NiMH rechargeable and disposable alkaline AA batteries cannot provide.
-------------------------
BACKGROUND & WHAT USAGE THE ENELOOP PRO IS INTENDED FOR
Eneloop is considered by many to be the tour-de-force of rechargeable NiMH cells (much like Panasonic is with lithium ion cells.) Gone are the days where NiMH cells did not give performance that came even close to alkaline. Things like memory, low service lives, rapidly fading capacity, etc. are over. Today we have NiMH cells that can dramatically outperform the finest of disposable alkaline batteries and can be charged thousands of times. Over a 10+ year period, you can save thousands of dollars with a good NiMH setup.
The eneloop Pro is eneloop’s (formally Sanyo and now Panasonic) follow-up to their highly successful eneloop XX series. Like the XX, the eneloop Pro is a SPECIALTY battery. It is NOT intended for usage with lower drain applications, and performs poorly when used for this purpose. However, when used in high-drain applications that tend to be brutal on the battery, the eneloop Pro gives unparalleled runtime that no alkaline can come even close to.
-------------------------
THE STANDARD ENELOOP 2100 VS THE ENELOOP PRO: Which is right for you?
Eneloop’s newest innovation is 4th generation NiMH cells. Like previous generations, eneloop is offering a standard-use and a high-drain model.Read more ›

[Note: The following is an updated version for my original “Sanyo eneloop FAQ”, first published in May 2012]
I have been using eneloop low-self-discharge NiMH batteries since beginning of 2007, and I'm completely satisfied with them. One thing I noticed is that newcomers to the rechargeable battery arena often have similar questions/confusions about eneloop. So here is my list of eneloop Frequently Asked Questions. This list is work in progress.
[Q1] Why are there so many eneloop batteries with different capacity ratings and cycle-life numbers?
[A] There are actually three families of eneloop batteries:
- Standard version: The original Sanyo eneloop (circa 2006) was rated for capacity of 2000mAh typical for AA (800mAh for AAA) and 1000-cycle lifespan. Subsequent generations advertise longer lifespan (1500/1800/2100-cycles) at the same capacity. The charge retention rates have steadily extended from "85% after 1 year" to "90% after 1 year; 70% after 5 years"
(Refer to my uploaded photo on how to identify different generations of eneloop cells)
- High-Capacity version: The original Sanyo XX (circa 2010) was rated for 2500mAh but only 500 cycles. The charge-retention rate is slightly poorer at "75% after 1 year". Newer Panasonic eneloop PRO bumped the capacity to 2550mAh and charge-retention rate to "85% after 1 year".
- LITE version: Those have half the capacity of standard eneloop but twice the cycle life. They are not marketed in the US.
[Q2] Do I get better performance from the latest generation Panasonic eneloop cells verses earlier generation Sanyo eneloop cells?
[A] On paper, newer generation offers longer cycle life and lower self-discharge rate.Read more ›
