7dayshop AA Ni-Mh High Performance Rechargeable Batteries 2900mAh: 16 Pack "4x4"

I am a photographer and use 7dayshop batteries for all my strobes/flashguns, as well as for kids toys and all kinds of other things and can only say that they are excellent ... these rechargeable batteries have totally outlasted named brands such as Duracell, Varta and Everyready batteries that I have bought in the past. The "recycle times" on my flashes are amazingly fast with these batteries on board and the amount of charge they hold is fantastic - 2900mAh is about as big as they come.The oldest 2 or 3 sets of these that I own must be nearly 3 years old now and I have probably charged them a good one hundred times if not more, but still they show no signs of losing any of their charge and they still produce excellent power every time.Once charged they hold a (near) full charge for several weeks without having to recharge or top them up unlike the Duracells, etc whcih I have used in the past which often lose their charge over just a matter of days.Downsides?? 7Dayshop don't deliver to the EU and I live in Portugal so I have to get them shipped to family in the UK and brought over or sent at extra cost, and the physical battery size is very slightly chunkier than standard AA's (probably due to their large capacity)... its not a problem generally but in a couple of cheaper components I have used them in which have small battery compartments they are a bit of a tight squeeze.Overall ... can only recommend these, they are dirt cheap and work, and the battery cases that they come in are really handy for transporting or just storing them when they are charged.I also mainly to use 7dayshop chargers with these batteries which have a refresh/discharge function - using this on a fairly regular basis definitely seems to help keep the batteries in optimal condition.

Fatter than the AA standard so difficult to remove from any battery compartment that you can squeeze them into. Something is wrong with these batteries in that there is no voltage drop to trigger digital battery chargers to stop charging them - they will just keep charging. Warnings on the chargers imply that might cause fires but I have pulled these things out of my charger before that ever happened. Terrible life - they just run out of juice in no time while in use. Terrible shelf life - by the time I grab the fully-charged batteries to use they are totally flat while the Eneloops that I charged alongside them are still nearly 100% fresh.Twenty five quid wasted in the most annoying way. I bought twenty four of these and they are all as bad as each other. Is that a coincidence? I will stick with Eneloops from now on.

Purchased 2 packs (32 cells) about 4 years ago and used them intermittently in Camera Flash Gun, Scanner radio and LED Torch.They claim to be rechargeable for upto 1000 times, i know that my batteries have only been charged a maximum of 12 times and yet so far 14 of the cells are dead and will not charge.Surely they should have a greater lifespan than 4 years, they were not in constant use, and certainly do not live up to the claims of... Last for years, Recharge upto 1000 timeI wrote to 7dayshop over my concerns and received the following response:HiIt sounds like the batteries have been left for too long without re-charge.NiMH batteries self discharge about 1% per dayRegards,So you must recharge these batteries every couple of months whether you use them or not.

I have been using these for a few years now for low drain applications (wall clocks etc) and they are now failing at a high rate - i.e. chargers reject them. That is apart from all the features mentioned in other negative reviews. Moving on to AmazonBasics ones now, which seem to have the same specs as Eneloop Pros (2500 mAh, 500x rechargeable, made in Japan)

I have used 7Dayshop before for many years.There own brand of rechargeable batteries are very good. I use them in all sorts of things from remotes to cameras. They hold their charge well and can be recharged many times before they fade.This batch is for my voice recorder which takes 4 of these. I used it yesterday and they went all day with lots of on and off cycles, half hour recordings and many reviews driving headphones. They are very good for the money. The only gripe I have is that they seem very slightly fatter than normal throw always and are sometimes a tight fit. Apart from this they are perfect for heavy duty needs.

I have many 7DayShop rechargeable batteries including 30+ of their AAs and have found them to be completely reliable and long lasting despite their budget price.They perform at least as well as every other brand I've ever tried including Sony and Duracell batteries.The cases hold 4 AA batteries and are a nice addition. Personally, I insert a little slip of paper between the batteries and the outside of the transparent case which has "Flat" written on one side and "Charged" on the other. As only one side of the paper is visible at once it means that you can use the cases to separate flat and charged batteries to help keep you organised.

Appalling self-discharge rates and most measure as 1800 mAH, despite running several "break in" cycles.Having recently obtained some brand-name 2400 mAH batteries (Duracell Recharge Ultra) and repeatedly achieved a measured 2400 mAH capacity plus very low self-discharge, I now fully understand why these "2900 mAH" batteries are so cheap - they're rubbish.

I am a bit late on this review but feel I need to say something. 6years on and these batteries are still going strong. I have only lost one of them after all this time which no longer charges. They charge up well and I put them on a regen cycle everynow and again. I simply cannot speak highly enough of the batteries and will chose them everytime.Keep going with these 7dayshop, they are awesome

Ich habe vier dieser Akkus überprüft und dabei zwar nur eine Kapazität von rund 2500 mAh (+-25 mAh) gemessen statt der angegebenen Kapazität von 2900 mAh,, aber für den günstigen Preis ist das noch völlig o.k.Eine LED-Leuchte, bestückt mit 3 dieser Akkus hielt immerhin 23:30 Stunden durch!

elles fonctionne bien mais ce sont des 2700 mah (c'est indiqué dessus en petit mais bien sur pas visible sur la photo)....alors que dans le titre il est indiqué 2900ma/h

Produit reçu dans les temps, exactement comme décrit et comme la photo. Reste maintenant à les mettre à l'épreuve... A voir avec l'utilisation
