New Eneloop Pro and Eneloop Plus rechargeable batteries

Just a quick update to the What are the best AA batteries for photography post from last week - Sanyo just announced in Japan two new rechargeable batteries: Eneloop Pro and Eneloop Plus. No details were provided when those new batteries will be available in countries outside Japan.

Tokyo, June 9, 2011 – SANYO Electric Co., Ltd. (SANYO), a world leader in rechargeable battery technology, is pleased to announce the new additions to line-up of the eneloop rechargeable battery series, the “eneloop pro”, the “eneloop plus” and their charger sets to be released for the Japanese market.

The new “eneloop pro” battery has a 25% higher capacity than regular eneloop batteries, making it especially suitable for gadgets with high power consumption, such as digital cameras, strobe lights and flashlights etc. The new “eneloop plus” battery, with its overheat prevention function which suppresses overheating in case of improper use, is ideal for toys.

In addition, SANYO will also launch the “Wireless Charging Carrying Case” which can wirelessly recharge eneloop batteries. The carrying case is compliant with ‘Qi*1’, a standard of the Wireless Power Consortium (WPC) who are working towards the international standardization of wireless recharging technologies.

The “eneloop pro” will be available from July 21, 2011 and the “eneloop pro” charger set will go on sale from September 21 in Japan only*2. The “eneloop plus” and its charger set will be available from December 1, 2011, also in Japan only*2.

SANYO, as a member of the Panasonic Group, will continue to expand the “eneloop” series throughout the world so that people can comfortably adopt a new "lifestyle that values reusing and recycling".

Main Features

  • Eneloop pro: Approximately 25% higher capacity than regular eneloop batteries.
  • Eneloop plus: With overheat prevention function for increased safety in case of improper use. Suitable especially for toys.
  • Wireless Charging Carrying Case: Wirelessly recharge AA and AAA-size eneloop batteries. Compliant with ‘Qi’, an international standard for wireless recharging technology.
*1 The “Qi” mark means that a product with the mark fulfills WPC’s standards for wireless recharging. The carrying case is useable with any charging pad with the Qi mark, regardless of the maker (Excluding certain models).
*2 The products will be available in Japan only (as of the release date).
*3 No manufacturer’s suggested retail price is set for a product with an open price.

    Have about 32 Eneloop AAs and they have served me well. My wallet hurts just thinking about this.

    The all-black exterior is a bad design. You can’t easily number them with a black marker. It is important to keep the batteries together in sets of four, so they wear down equally. The all-while exterior makes this easy, with lots of room for large numbers. If you put a paper label on it, they peel off, and are often too large to fit some flashes. And it adds another layer of thermal insulation – a bad idea.

      I have a silver pen, white pen, metallic pearl pen. You can get it from art store.

      Pick up the metallic silver Sharpie markers at Staples or Home Depot. They work great for marking black surfaces like AC adapters or electrical boxes.

    But there *are* already Eneloops with higher capacity out there called Eneloop XX. What’s the difference?

      Where can you find Eneloop XXs? And are you sure they’re not counterfeit? I have’t seen anything regarding the XXs since they were announced about a year and a half ago with the statement they’d be available sometime later…

        Indeed, there are a lot of fake batteries about. The margins are high and often it is difficult to tell a good battery from a bad one until days or even weeks later. Most consumers could not tell a repackaged factory reject from a top branded battery.

        I buy all my rechargeable batteries at Battery Collection in Hong Kong, including the Eneloops and XX’s shown in the article and accompanying photo. Battery Collection is a large well known chain with a stated commitment to selling original products. Any other vendor with a reputation worth keeping and enough customers so that deception would be noticed is better than buying from a market stall or anonymous on-line vendor.

        The black XX Eneloops are available in some of the large computer shops that also sell P&S cameras. I’ve never seen then in a camera brick and mortar. Contact Sanyo and ask who distributes the batteries in your country and then contact the distributor to get store locations..

        Hope this might be of help…..

      The difference between the existing Eneloop (2nd Generation) and the XX are the addition of a “positive temperature coefficient thermistor” which is designed to cut out batteries before they reach high temperatures. They are intended for primarily for toys. The trade-off is slightly lower energy storage, about 100mAh less.

      Incidentally, I have put my eneloops and XX battery sets through a few cycles under near ideal conditions and at this point, they should be at the optimum performance. I have found that they have not reached their designed ‘typical’ capacity ratings of 2,000mAh and 2,500mAh respectively, and in some cases have fallen short of their ‘minimum’ capacity ratings of 1,900mAh and 2,400mAh. Therefore, either I have not done the experiment right, two Powerex MHC9000 analysers are not reading right, Hong Kong’s most prominent seller of batteries has sold me duff batteries, or six sets of four eneloop brand batteries haven’t lived up to their advertised capacity rating.

      I am not saying that I believe eneloops are not the best choice in ULSD NiMh AA batteries, as I am told that many manufacturers stretch the truth, but my point is batteries with protective circuits are likely to further reduce available capacity. In an external flash, the flash head is likely to cut out before the batteries cut out, but an extra protective circuit simply increases the chance of the flash inexplicably failing to fire at a key moment.

      I understand why these batteries are targetted at they toy market, but really, if a toy is likely to draw enough current to harm a child or start a fire, then that toy is badly designed and has no place in my home.

    i just bought some Sanyo Harmolattice batteries. they ve been around the market for only a coupld of months. metallic red, ‘low self discharge’ 2500mAh. supposed to retain 80% of charge after 6 months and 75 after a year. kind of like a beefed up eneloop i suppose..

  • malez

    the pro and plus batteries are of different size…

  • Borris Chucks

    I bought a pack of 4-AA Sanyo XX [the name used prior to Eneloop Pro], a few months ago. While they do have an extra 25% capacity, whether your needs dictate spending quite a premium is up to you.

    If I were to do it again, I’d hold back on purchasing an excess number of eneloops, tones, duraloops etc. They’re not doing any good sitting on the shelf unused. I probably could get away with owning 8-12 AA’s, but I let sales prices get the better of me.
    I have some eneloops that are over 4 yrs. old and are starting to degrade, meaning their capacity is no longer meeting minimum specs. [1900 mAh]. These batteries are hovering around 1800 mAh, which still isn’t bad at all, but goes to show they’ll likely degrade long before I reach 10 or so years….we’ll see :) Testing done on a mh-c9000.

    For the common user though, just grab some eneloop plus / tones / regular etc. They’ll last alot longer on a charge than Eneloop Pro. This has the advantage on low power devices like remotes, battery clocks etc where a regular eneloop will hold the charge longer.
