 * Feel free to elaborate. --TheEcoDude (talk) 01:51, 20 October 2011 (UTC)
 * All there is to know about eneloops is the difference between the revisions, and I think that info is covered pretty extensively here now. Which information do you expect to find here? Other than that, the 4 typos obviously have been fixed. What a shame, 4 typos. And people actually said that rapture was a hoax... --TheEcoDude (talk) 01:18, 6 November 2011 (UTC)

Eneloop Pro vs. Eneloop XX
I think the Eneloop Pro (2,400mAh) is called Double X in Europe and is different from the XX Powered by Eneloop (2,500mAh XX series). But could be confusion between different marketing in different countries. Engadget Eneloop Pro
 * The %75 retention after one year is when the battery is not used, but sounds here like it can't fully charge after one year of use. I'm not sure if that pertains to the Pro or the XX.Michaelsammler (talk) 00:44, 22 January 2012 (UTC)

Eneloops in C or D format
I haven't seen any information about eneloops in C or D format (other than the adapters) aside from in this article, which claims that these formats are available in Japan - however the link is dead. Can someone update this? — Preceding unsigned comment added by 129.12.250.153 (talk) 00:52, 2 November 2012 (UTC)

Capitalization of the term "Eneloop"
The Wikipedia Manual of Style says that all-lowercase trademarks, such as eneloop, should always be capitalized (i.e. written as Eneloop) when used in Wikipedia. I wonder if someone could please fix the article so that the article matches the Manual of Style and the rest of Wikipedia? Kind regards, &mdash;Unforgettableid (talk) 01:57, 10 April 2013 (UTC)
 * It now complies with MOS:TM. If someone could double check and make sure I didn't miss any that'd be great.  Я ehevkor ✉  19:37, 28 October 2013 (UTC)

Suggestion: add pronunciation for "Eneloop"
I was not sure how you pronounce Eneloop (een-loop, en-loop or any-loop, etc.)... This would be helpful IMHO. — Preceding unsigned comment added by 180.200.159.60 (talk) 04:21, 12 October 2013 (UTC)


 * It would be interesting to know where the name comes from. Panasonic's website says (vaguely) that the name was based "on the concept of recycling energy", so presumably it's supposed to make us think of an "endless loop" (or an "energy loop"). In which case it would be pronounced "en-a-loop". -Ashley Pomeroy (talk) 22:37, 18 April 2015 (UTC)

Panasonic lite lifecycle
Everywhere I look i says that rebranded Lite version can be recharged about 3000 times, not 5000. 83.6.200.192 (talk) 13:27, 27 June 2014 (UTC)
 * I agree. The original Panasonic page referenced in citation #9 of the Wikipedia article, which purportedly supports the assertion in the article that Panasonic's eneloop lite can be recharged 5000 times, returns a 404 error message. The archived version of the page on the Internet Archive Wayback Machine (IAWM) [1], however, refutes this assertion, stating clearly:

Rechargeable up to 3000 times

eneloop lite is rechargeable up to 3000 times, which makes it even more economically and environment-friendly. By reducing the amount of materials used, attractive prices have been realized.
 * Further, the current version of the Panasonic page [2] confirms that the lite version can be recharged 3000 not 5000 times.

 * how about their official Japanese site (http://panasonic.jp/battery/charge/eneloop/) that states 5000 times! both in text and in pictures, the latter should be less considered to be a mere typo, especially when graphically explained the increase of exactly those 3000 times from 2000 to 5000)? — Preceding unsigned comment added by 217.159.171.19 (talk) 16:51, 20 April 2015 (UTC)

Made in China vs Japan
This article needs to mention the differences in Eneloops since the Panasonic purchase. The newer chinese version seem to be quite inferior compared to the Japanese versions. I've had a look at the Edit history and their appears to be an edit war going on regarding the Fujitsu/FDK details. From what I can tell the newer eneloops are just Eneloops by name only and the original Japanese manufactured Eneloops are now Fujitsu (and other rebranded) brand ones.

From this forum: "It's speculated that when Panasonic purchased Sanyo, they only acquired the Eneloop brand and the Japanese factory that produces Eneloops was sold off to a third party to ensure that there weren't any anti-trust issues that would otherwise block the purchase due to Panasonic potentially controlling an excessive proportion of the worldwide battery production capacity.

 * I have written that first statement about FDK. It is very well known fact from within the industry (I have this information from the primary Eneloop distributor here who also distributes Fujitsu now) but you can find articles regarding that - which I did, everything has been cited, look at the old revisions. Panasonic owns NO Ni-MH factory at all from the Sanyo acquisition. They had to sell everything off to not get total monopoly. That ais also the reason why shortly after the acqusition many series of Ni-MH batteries were written off and never got any replacements.


 * So I would like to know the true reason why it is still being removed - Panasonic agents kicking in? Because that argument about "primary research" is just BS, there is nothing like that. This has been known for 6 years now, just that Panasonic of course never had any interest in spreading the information so little number of people know about that.


 * Anyway, what are the "chinese versions"? Never heard of that.(Behemot (talk) 00:21, 21 October 2015 (UTC))

Wh capacity calculations? Are the tables right?
I think Wh is amp hours * volts (volts will drop as battery drains)

The tables confuse me for example AA
 * 1st generation 2000mah 2.4wh - that makes sense to me, because these are 1.2 volt nominal batteries
 * 4th generation 2000mah 5.040wh - that does NOT make sense to me because I think that means a 2.5 volt output. — Preceding unsigned comment added by Antifesto (talk • contribs) 00:45, 9 September 2015 (UTC)


 * It is meant capacity over lifetime, so the capacity in mWh times number of cycles. (Behemot (talk) 14:20, 12 November 2015 (UTC))

HR-3UTGA ?
According to this article the 1st generation is marked HR-3UTG, and 3rd generation is marked HR-3UTGB, mine are marked Sanyo HR-3UTGA, min 1900 mAh, made in Japan. I assume they are 2nd generation, don't know when I bought them. — Preceding unsigned comment added by 2A02:908:1865:3140:2160:F1F7:8B9D:24D7 (talk) 11:01, 11 November 2018 (UTC)
 * Yes, from Japan wikipedia they are 2nd generation. 109.252.171.205 (talk) 07:23, 25 June 2020 (UTC)

Eneloop & Lite lifespan comparison
I don't know if this can go in the article without being considered Original Research, but looking at the total energy delivered by Eneloops and Eneloop Lites, the figure is the same (~2100Wh for AAA size). So, if used to provide steady low power (DECT phone), they will both have the same lifespan - the Lites will have to be charged more frequently if allowed to discharge completely, but this will be exactly compensated for by the larger number of cycles (3000 vs 2000). The non-Lites will let you leave the phone off the hook for a few more days before needing to recharge (longer endurance), but if you always charge overnight they will behave exactly the same, with the Lites doing so more cheaply.

Why is 2022 Eneloop Pro AA min. 2500 again?
Newest packages all have minimal (not typical) at 2500 mAh. That was CC generation. CD generation has min. 2550 mAh. 109.252.166.131 (talk) 00:20, 23 August 2023 (UTC)


 * Oh. okay. Min. 2550 is a Counterfeit Eneloop. 109.252.166.131 (talk) 00:47, 23 August 2023 (UTC)
