Top Customer Reviews
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 ›
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 ›
I also use the current generation of standard eneloop rechargeable batteries on various gadgets and toys around my house. I would not recommend the :envelop pro" batteries for everyday use, not because they would not work, but because there is no need for a battery of this caliber for most things.
I will never go back to using any other type of rechargeable battery.
I use a La Crosse Technology BC-700 to charge the batteries and have never had an issue with heat dissipation.
I made a comment in my review of the regular eneloops that it was a hair thicker than regular alkalines. Devices with extremely tight-fitting battery compartments may face an issue using the regular eneloops. The eneloop pros perform even worse in this regard; they are yet another hair thicker than the regular eneloops.
Devices with formerly little or no issue with the eneloops now face a variety of situations with the eneloop pros. Removal of the batteries from the battery compartment of the Xbox 360 wireless controller, for instance, became next to impossible without some ingenuity. Cursor movements with the Microsoft Wireless Mouse 5000 became sluggish due to the ever-so-slight protrusion of the battery cover, creating extra friction with the table surface.
Panasonic should have put a discretionary label informing users of the additional thickness between the eneloop and the eneloop pro. Unless you're certain of the battery slot tolerances of your appliances, save yourself the frustration and get the regular eneloops instead.
