Hybrio / Eneloop type AA batteries. i.e. they are charged and ready to use, and hold their charge for up to a year.
Bargain price if they perform similar to Hybrios etc. I've used 7ds batteries for many years and found them reliable and well performing.

Price reduces if you order multiples (e.g. ranging from £4.49 for 1 pack down to £3.89 for 10). Includes postage.

"JUST ARRIVED BY POPULAR DEMAND - 7dayshop.com Good TO GO batteries arrive pre-charged and ready to use. Additionally they hold their charge for longer times than traditional Ni-Mh rechargeable batteries and can be recharged up to 1,000 times...
7dayshop.com "GOOD TO GO" are the similar/same in technology as Sanyo ENELOOP, Panasonic Infinium, Uniross Hybrio, GP Recyko, Sony Cycle Energy, Duracell Active Charge, Hama Ready 4 Power and Camlink's Ready 2 Go batteries - Only Much Better Value of Course !!
Ni-Mh (nickel metal hydride) type batteries are favoured by demanding users as they are memory free and offer superb performance over traditional Ni-Cad rechargeable and also single-use Alkaline types. These 7dayshop.com batteries are compatible with all good quality chargers and equipment types too.

AA size batteries are also known as LR6, LR06 and MN1500

These AA batteries are supplied with a FREE plastic (semi-transparent) storage case, which will help to look after your batteries and also prevent possibly dangerous short-circuits in your pocket or case etc. These cases are modular and can be linked together to provide a larger/longer case. We also sell these cases separately (and in differing colours) to help with battery rotation etc.

Ask yourself why Ni-Mh rechargeable batteries becoming so very popular ?
Because using rechargeable batteries will save you hundreds of £££'s over using "single-use" batteries. They cost only a few pence to re-charge and can be used again and again (up to 1,000 times in fact). Very often they offer better performance than even the best one time use alkaline batteries on the market today. The charging technology has also moved forward and it is now possible to re-charge Ni-Mh batteries in much shorter times than was possible before and a big extra plus is that they are also kinder to the environment as you are not throwing batteries away to landfill sites.

good price although 'unknown' quality

adds only 7 degrees heat ...! hmm was 9 and posted a few more deals which got 100+ heat and now dropped
ah well

Everyone's heat dropped.

Good deal, could do with a few batteries although was slightly disappointed in some of these new types of batteries I got a few months ago, don't seem to hold their charge as well as they're supposed to. I wonder if anyone has tested them scientifically?

Damm which ones are best vapextech or Sanyo eneloop or these ones? I currently use Fujicell 2500 mAh and they are s""t dont last long and the charge dissipates quickly when not in use, looking to upgrade.

thnx for heat info

sure i saw some tests on the batteries on a camera user forum but was pretty soon after they came to market so only a few tested.
plenty of simple ones on net now like :stefanv.com/ele…tml for an idea

I've used 7DaysShop batteries a lot, and I have continued to buy them as they're great value and great performers. Never had these from them though, but I've no reason to think they'll be any less impressive.

The thing I've found with this breed of battery, is that the device tends to relatively quickly show that the charge level has dropped, but then it stays like that for ages and ages, continuing to give level power. They do indeed hold power without use for way long enough before i finally use them up too, which is the point of these.

I tend to use "regular" ni-mh (2800mAh 7 day shop...) in my camera & flash, keeping a set of Hybrios in the bag as back-up.

Anyone else having problems paying on their site? I've tried and failed with 2 cards

Can't say about Sanyo because I don't have any but I've found the Vapextech to be very good.

The Vapex AAs I received last week didn't have cases in the pack, though Vapextech.co.uk put some in the envelope, and I thought they looked different though I haven't had time to compare them in any detail. I hope they are as good as they have been in the past.

Have some heat from me. I've ordered and will leave feedback when I've tried them for a while.

I dont get the point of these. They're lower capacity (2100mAh) than cheaper normal NiMHs (even from the same site). Unless you literally have to use them as soon as they come through the post, surely its better to get 2800mAh ones, then charge them up ready. Higher capacity, lower price....

To me they seem like a gimmick...

Still... Heat added, as if you want them, it ain't a bad price

These hold a charge for a much longer time. Normal NiMH go flat even without use.

The point about this is not that they come fully charged, but that they will hold there charge for up to a year. a normal NiMH will start to loose its charge fairly quickly so they are no good for keeping in a torch that only gets used occasionally, in an emergency for example

The good thing about these batteries is that they are low drain when not in use. I can charge them up and stick them in the cupboard for a few months and not have to worry about them running out half way through a vital task. I use a set as spares for my digital camera

With normal recharables I'd have to do a top-up to make be sure I've not court short

Good batteries. I have a few sets of these and they hold their charge really well. Good for in my wiimotes

Rechargeable batteries operate at a lower voltage 1.2V vs 1.5V in a normal battery. I'm not an electrician, but I believe that voltage drops as the battery runs down, therefore a rechargeable battery may look to the device as if it is low when in fact it is running normally. To clarify a normal battery can drop from 1.5V quite quickly, but a rechargeable one maintains about 1.2V for most of its charge.

Except if you don't use the high capacity batteries quite soon after charging they lose most of their extra capacity advantage whilst low self discharge batteries keep a higher percentage of their charge for vastly longer. E.g. you can't really charge the high capacity ones 'ready' unless it's close to when you need them. See here: stefanv.com/ele…gif

I'm new to the rechargeable battery scene ... £4.49 for 4 batteries seems quite pricey to me ?
I would need 8 of these to keep 2 wii motes going. Any suggestions on a charger to go with these ?
Thanks
Adam

Great batteries. Want to start moving fully over to these, as normal Ni-Mh batteries are a pain due to how quick (in comparison) they discharge. So these now go in things like my digital camera, controllers and even my cheap electric toothbrush. So whenever I go to use my digital camera now, I don't have to worry about the batteries losing their charge.

This is very good as it charges each cell individually. They sell smaller ones too with Delta-V technology .

Good price in comparison to the Brand names. I usually buy the Hybrio ones from eBay for about £6.49 but at £4.49 these may be worth a pop. Are 7dayshop trustworthy?

IMHO, yes they are very trustworthy.

They have been around for years, and I have ordered many items such as batteries, memory cards and ink. I've never had any issues with them, and their prices are usually great (inclusive of delivery remember).

Actually, the 2800mAh is more expensive at £5.29 :p. These are not a gimmick, just different, as someone else above explained.

And cheers for the heat!

anyone know who makes these batteries? doubt if 7dayshop make them, more likely to be rebranded other manufacturer

When you consider that the cost of charging them is less than 1p, and that they can be recharged hundreds of times, then the initial cost is laughably small compared with the cost of disposables. Unfortunately there still seems to be a rich seam of the hard of thinking who can't quite work that out.

I think the poster was comparing them to other >2000mAh rechargeables that you can pick up for

And of course those batteries he is talking about would be "standard" rechargeables too, not the hybrid type. Note that I have tried the cheap types from Aldi in particular, and they are rubbish. They now sit dormant in a drawer, the only reason I wont throw them away is because this goes against the ethos of having rechargeable batteries!



Why not take them back? (unless they are really old)
I've some ones I bought in Aldi and they are working fine.
I've also got some from Lidl that were even cheaper (but they sell out fast)

Perhaps you might wish to explain to the poster who is new to rechargeables why you think hybrio are better than the standard, cheaper ones. (other than you appear to have got some duff ones)?

OK thanks guys. I would say something about 7dayshop batteries though: I bought a twin-pack of LiIon cells for a Panasonic TZ3 camera and, despite the effusive description, they are not a patch on the original. Doesn't mean these ones aren't good of course, but not all 7dayshop batteries are excellent.

I didn't mean to say these are better - these are a different type of rechargeable.

The Aldi rechargeables are of the standard type, and in comparison to to my other standard types, they are poor, seeming to hold charge for and run down in a far shorter time. To be fair their mAh is rated lower in the first place, but seeing as the others I have were only very slightly more expensive, the Aldi units are not worth me buying again. Not faulty I suspect, just not what I'm used to.

Note: I love Aldi.

How do these batteries compare with Vapex ones?

I can buy 4 instant 2100MAH batteries for £4.50 anyway, but theres £2 postage aswell!

Should I get the Vapex ones or these?

It also appears that there are only 2/3 battery manufacturers hence these maybe identical as eneloop or hybrio ones? Anyone care to comment on this?

I don't think anyone here has actually got any of these yet as they're new - some on order by the looks of it. Similar specs to the Vapex I think? Spec is higher than Eneloops which are 2000mAh.

I'd be happy to try these instead of the vapex, but then I'm a repeat user of 7dayShop.

I suspect we'll never find out who actually makes these. Unless we do a side-by-side dismantle test! Could be messy.

I don't know whether it is the best charger or not. Everyone has his/her own opinion. One of these has done the job well for me for over a year so I recommend it.

An explanation of Delta V

Batteries are charged at constant current of between 0.5 and 1.0 C rate. … Batteries are charged at constant current of between 0.5 and 1.0 C rate. The battery voltage rises as charging progresses to a peak when fully charged then subsequently falls. This voltage drop, -delta V, is due to polarisation or oxygen build up inside the cell which starts to occur once the cell is fully charged. At this point the cell enters the overcharge danger zone and the temperature begins to rise rapidly since the chemical changes are complete and the excess electrical energy is converted into heat. The voltage drop occurs regardless of the discharge level or ambient temperature and it can therefore be detected and used to identify the peak and hence to cut off the charger when the battery has reached its full charge or switch to trickle charge.

Spec is higher than Eneloops which are 2000mAh.

Unfortunately you can take such figures with a large pinch of salt, especially when considering such tiny variations.

Ordered 2x AA and 2x AAA. Seem a pretty good price.

Plus I won't be buying normal NIMH batteries anymore, these instant ones that hold charged are much better for me as I don't use a high drain device all the time (quite rarely), so these are much better.

Charge and forget. Great idea!

Not sure if the ones in this thread are listed in these tests. The first link is just Eneloop v Recyko

Theres more to it than that. In the long run they are ofcourse cheaper, but I know that I'll never need to worry if I've got enough alkaline batteries.

Buying 8 batteries will last for a very long time and anytime I need them I know I can just charge them up! So it's more peace of mind for some people rather than the cost.

Not sure I understand you - you seem to be saying initially that having alkaline batteries is necessary in order not to run out of batteries, but then you say that they aren't necessary because you can just charge up the rechargeables.

What I mean is that, if I were not using rechargeable batteries (i.e. I had normal AA duracell ones), then I'd have to make sure I have plenty stock, so I don't have to run to the shop if they run out of my mouse or keyboard etc.

Whereas with rechargeable ones - I just buy them once and then never worry. If any battery becomes low, simply recharge. I don't even have to think about how much stock of AA batteries I've got.

Rechargeables are cheaper - but more importantly less hassle.
