Panasonic eneloop pro ready-to use Ni-MH battery, AA/Mignon, 4-pack, min. 2500 mAh, 500-charge cycle life, with very high power performance and low self-discharge, rechargeable battery

I've been purchasing rechargeable batteries for years now. I have a man drawer with a few spares in that have been charged up so I always have some handy when I need them. Unlike non-rechargeable batteries I find that you don't get much warning with Ni-MH ones before they are nearly completely depleted so it's a good idea to have a few pre-charged ones spare. Despite lots of devices using Li-Ion batteries these days I've actually found that the number of devices around the house that require AA batteries has increased. Things like digital cameras, remote controls, wireless computer keyboards, wireless mice, console joypads, Oculus Rift/Quest VR controllers, children's toys and even electronic doorbells, to name a few, all still seem to require them. The nice thing about these batteries is that they arrive pre-charged (with solar energy!) so they don't require charging (although I suspect they will not be charged to 100%). They also claim to retain 85% of their change after 12 months if they are not used which is great news for the ones that I have stored in the man drawer. These can also be recharged up to 500 times... if that's true then these are going to last a long time! Of course it will be difficult to verify these claims for a while but if they fail to live up to expectations then I will update my review. These seem to be genuine batteries and look like the real thing and I've had no issues with the ones I've used so far. Pros: - Good value compared to regular non-rechargeable batteries - Slightly higher spec than the 2500mAh Duracell batteries - 2500mAh so should be good for more demanding devices - Batteries come pre-charged (although unlikely to be 100% charged) - Hold their charge when not in use (i.e. 85% of charge after 1 year) - Can potentially be recharged up to 500 times - Better for environment than non rechargeable batteries as you are reusing them repeatedly as opposed to disposing of them (batteries are full of harmful chemicals and heavy metals). These are also pre-charged using Solar energy which is much greener. Cons: - Perhaps a little expensive when compared to non-rechargeable batteries but they really do pay for themselves after a few charges. - You get very little warning when the batteries are running out of charge. Always a good idea to have some on standby. Neutral: - As with any rechargeable batteries they require time to recharge

Rechargeable batteries like these are well worth the initial outlay as they can be used over and over again over a number of years, thus saving money on single use equivalents and avoiding the consumption of all the raw materials used in their manufacture.

I have a load of these batteries that I have accumulated. I was fed up of never having 1.5V cells and at Christmas time we go through a silly amount of these with the Christmas lights. So I ended up doing a bit of research into which are the best rechargeable batteries on the market, and these seemed to crop up a lot for the performance, life and just being all round good batteries. My only issue is reminding my wife not to throw out the black batteries because they're rechargeable, she forgets though, so I have to top up and buy more every so often! Not the cheapest on the market, but they're good and I've not had any issues. A top tip if you have a battery that has discharged too much, then if you use another full battery of the same size, you can push the "bases of the dead and the working battery together and then use ditching tongs (as long as they're metal and "short" the nobble ends of the batteries together for 30 seconds. This allows the battery to reverse charge and it provides enough of a kickstart that will then allow the battery to be re-charged, it's very satisfying when a battery goes from not being detected to charging after this trick!

These are nickle-metal-hydride (NiMH) rechargeable batteries which produce 1.2A of power. Eneloop batteries are designed to have a very low self-discharge. Older rechargeable batteries will self-discharge about 20% on the first day and about 5% per day after that. Eneloops still retain 80% of their charge after a year. They're great for LED torches, cameras and digital radios. Eneloops also have a higher capacity (measured in mAh) than many non-rechargeable batteries. The fact that they last longer and can be recharged makes them the best batteries on the market. They're Japanese and their quality is second to none. There are two main types of Eneloop battery - the black-coloured ones have a higher mAh capacity but will take fewer recharge cycles (~500), whilst the white-coloured ones have a lower mAh capacity but will take more recharge cycles (~2000). For example, people who work in the emergency services will probably want a higher mAh capacity so that their LED torches will last longer, and people who play video games will want higher mAh for their wireless controllers. The lower mAh capacity are more suited for cordless phones, TV remotes, or for people who don't use their torch or radio every day - e.g.,an emergency torch stored in a vehicle, kitchen or bedroom. In practical use, the black-coloured Eneloops last about 35%-40% longer between charges than the white-coloured Eneloops, but the white ones can be recharged 4 times more. Obviously you also need a good quality charger to get the most out of these batteries. There are a lot of different chargers on the market so shop around. Eneloop even sell a charger with batteries included. Personally I use the Ansmann 16+ charger - it's expensive, but probably the best there is. It's also huge! (Ansmann make smaller 8+ and 4+ versions.) The XTAR VC4 is also quite good and the Nitecore chargers work well too.

I bought a set of these a while back and am pleased with them, although I'm not sure how much more charge they really provide over the standard ones. I have a hunch that one of them my be underperforming as the unit they're used in fades a bit quicker thn expected sometimes, but other than that they've been fine. I also have the standard Eneloops and think they're great after several years of use (although I note that the prices have rocketed in recent years).

I've had these 4 years, I bought two sets for my audio analyser equipment... I didn't realise that my the analyser requires 1.5v batteries until id been using them for around 1 year, I took meter for calibration and they gave me a set of 1.5 volt batteries, I called and explained id been using these for a year and as these are 1.4v I didn't realise they should be 1.5v. ..the guys calibrating could not believe this as normal Duracell 1.4 last just a few hours, I explained these past a good two days testing and they said this is amazing... I have now had these for years and they are still going strong and I can stress how good these are... 10 out of 5 .. very very happy...

I’ve bought many packs over the years and have never had any issues. They are not quite as powerful as disposable batteries but they don’t take long to charge and last long enough. We use them 100% of the time now so consider the value very good in the long run.

Good batteries

Har bara laddad dessa batterier ett fåtal gånger från att jag köpte dessa batterier eftersom de håller så pass länge.

I use these every day and they last much longer than written on the package.

Endlich mal wieder Akkus die ihr Geld wert sind und sogar mehr leisten als Beworben! Vorwort: Die letzten Jahre habe ich leider öfters beim Discounter zu den üblichen 4er Pack NMHi Akkus gegriffen. Die Angaben stimmten hinten und vorne nicht, wenn 3000 drauf stand konnte man schon froh sein, wenn nachher 2000mAh reingeladen wurden. Dazu haben die eine Selbstentladung, wo man sein Geld auch gleich doppelt Verbrennen kann. Vor drei Jahren habe ich sogar meine Digicam weggeworfen, weil ich dachte die wäre Kaputt, ging selbst nach dem Aufladen gleich wieder aus mit der Meldung Akku leer? Nach dem ich mir ein sehr gutes BC700 Ladegerät gekauft habe, sah ich die Akkus waren Teilweise kaputt! Billig Ladegeräte zeigen nicht die Tatsächliche Leistung an, denn trotz hohem Volt wert können diese Defekt sein, wichtig ist die Leistung in mAh (mil. Amper Stunden) und wie lange die X,XX Volt gehalten werden können. Ich habe schon die kleinen Eneloops "AAA" gekauft für meine Fernbedienungen und Festnetztelefon, dort begeistern sie mich schon über ein Jahr. Jetzt habe ich mir eine neue Digital Kamera gekauft und da mussten neue "AA" Akkus her, anstatt kaufe Billig, kaufe zigmal, dieses Mal gleich Eneloops und wie zu erwarten alles bestens. Zur Sache: Die PRO kamen bei mir als neuste Version an, es gibt Unterschiedliche. Anhand der Firmware/Serial Nummer auf dem Akku können sie das Nachprüfen, viele Händler hier geben auch in der Artikelbeschreibung schon die Info. Die Akkus sind auf Grund ihrer geringen Selbstentladung schon fertig vorgeladen, sie können sie also auch gleich Verwenden so wie bei wegwerf Batterien. Die Pro Variante kann mindestens 500 mal wieder Aufgeladen werden, bei der Normalen Version mit weniger Leistung 1000 mal. Die garantierten Zyklen, sind bei der Pro niedriger, weil die höhere Leistung den Akku mehr belastet. 4x500 Ladungen macht insg. 2000, selbst bei billig Alkaline wegwerf Batterien werden sie noch Geld sparen. Die Akkus habe ich im BC700 gleich mal mit dem "Test" Programm (Entladen/Aufgeladen) beackert, alle 4 Lieferten über 3000mAh! Damit mehr als Angegeben, die Angabe auf der Verpackung bezieht sich auf die min. Leistung die Garantiert wird! Hmm, da könnten sich die ganzen DSL/Cable Buden mal ein Beispiel dran nehmen :P Grund solides Produckt, was jeden Cent wert ist! Die 5 Sterne mehr als verdient. Info: Zur Haltbarkeit, kann ich bei der Pro Version noch nichts sagen, sollte es da Neuigkeiten geben, gibt es hier wie immer ein Update bei mir!

Ya conozco esta marca de pilas hace años, y de momento están demostrando una calidad superior a algunas marcas más conocidas.

Sans aucun doute les meilleurs accus rechargeables du moment, tant par leur fiabilité que la rapidité de recharge ou leur tenue dans le temps. Je m'en sers essentiellement pour alimenter mes flashs cobra Nikon SB700 et SB800 et ils me permettent de tenir sans soucis environ 150 déclenchements a pleine puissance, ce qui est vraiment excellent en comparaison d'autres marques. Les batteries constructeurs de Godox sur AD200 ou V860II sont nettement meilleures, mais si vous possédez des flashs cobra qui utilisent des piles AA, optez pour ces Eneloop, vous ne le regretterez pas. Bien évidemment, elles pourront aussi vous servir à d'autres usages... Amusez-vous bien !
