Hi, first post so be gentle

I was looking for some high-powered batteries for my flashgun and came across these, there excellent and long lasting at 2900mAh, the price is a bargain and the more you buy the cheaper it gets.
Not a top brand but does the same thing and much cheaper.

hope its helpful

Yes they are fine, and occasional users might "need" the higher capacity as opposed to the shorter time they take to loose charge, but for the vast majority, their own brand Low self discharge ones: Good 2 Go will be more convenient, despite the nominally lower capacity -

If I fully charged the 2900 and put them on the shelf, how long before they self discharged enough to be the equivalent of 2100mAh?
A day? A week? A month?
I'd be interested to know.
Personally I own both, and love both.

I agree with all the above. Though I have used rechargeable batteries
for years the rapid charge loss used to irritate me on a grand scale.
With these the problem is solved. 7 Day shop say only 35% of
people use rechargeables. 65% are therefore balmy.

longer than month, I think most people just exaggerate quality of good to go ones, as I've read many reviews and no one seem would give proper, clear explanation with any test's done along with their comments/reviews.
Imo it is like an effect with placebo pills. Somebody claims, that after "week on a shelf" their ordinary nimh batteries completely discharged,whereas "good to go" still hold the charge", which is clearly misleading, as my 3-years old energizer (1600mAh) does hold charge after a month on the shelf,same with duracell, uniross and noname brands in different sizes(aa, aaa, d, c). although I don't have equipment to test this, but, do they have it, to support their claims?

Not in depth but my energizers 2100mAh AA in an energizer slow charger in my Canon A10 camera last a few days - with minimal use. I've got some 7Day Good to gos that have been in that camera for about a month and there's no Low battery indicator yet.. Hope this helps somewhat.

It is not a placebo effect .There is definate proof that "'low slow-dischage" rechargable batteries are just that! And for the vast majority of applications, good-2-go batteries (there are many makes/names but first developed by Sanyo) 'low self-discharge' are far superior to 'normal' HiMh rechargables. This guy did a brill review a few years ago - gets technical but proves the point - http://www.stefanv.com/electronics/sanyo_eneloop.html . Additionally, it is evident re the low-discharge because when you buy them you can use them without charging - they are charged before packing - and if they are sold within, say 2 years, they will work from the packet. Contrast that with normal NiMh recharagables which are not charged before shipping. See Sanyos info site http://www.eneloop.info/

There are other benefits than the 'self discharge" - they last longer in use - even ones that are a lower rating compared to higher rating normnal NiMh.

I have used rechargable for years - NiCd then NiMh and have now used these types of batteries for about two years. The effect on my digital cameras is very significant. Normal rechargeables do go flat very quickly - within weeks - in a camera swiched off. Not so with these new types. Also they last far far longer when the camera is in use.

If anyone is considering recharagable batteries then there is no point in NOT buying 'low self-discharge' IMO. If you don't believe it - buy a pack - same price or cheaper than normal rechargable - I am convinced you would not regret it!

We have good to go batteries in our shower radio - normal rechargables would require charging after a few weeks - now it is more like a few months in between charges, obviously the radio is only on during the shower/shaving time.

Definately the slow discharge batteries are miles better.

I bought one of these (or at least it looks like that) from 7dayshop. The instructions I got didn't say what the Refresh/Charge button did though I have just discovered today what it does. I put one battery in the unit which I know goes flat in next to no time and put it on 'Refresh'. Within 10 seconds the display changed from Refresh to Charge so it looks like it wasn't doing a refresh at all.

Other times when I put batteries in the display flashes on an off on some of the batteries. Again the instructions don't tell you what this means. I assumed it meant the battery was no good as it didn't seem to charge but when I put it in another charger and charged it and then returned it to the 7dayshop one the flashing on and off did not happen.

I therefore became unsure as to whether this charger was doing what it was supposed to with some batteries. It wasn't just old ones it did it with either. I had one Eneloop type which had only been used once and it didn't seem to like that one either.

I wrote a review on 7dayshop and it never got published so don't rely on the comments on there. They only publish what they want to.

So - following a comment on here I have just gone for the Speedy Box charger for £14.99.

http://www.7dayshop.com/catalog/product_info.php?products_id=100598

This is a proven charger and is a rebranded Vanson Speedy Box

This one is supposed to be even better but only does AA and AAA batteries and is almost double the price

I'm a caver, and I use these batteries in my lights. My life depends on them, and i find them to be good, long lasting, reliable batteries, and a really good price. And I find they hold their charge for a reasonable amount of time.

In other words, they're great for intense use, hold charge reasonably well, but obviously aren't designed for use in a shower radio etc

Hope that helps

That's interesting I get the same, I just leave the battery in there and the flashing stops and charging begins. Same as you I have no idea on what it means.
#19
Usually a refresh button would discharge the battery first, so if the battery is already flat, it will quickly sense this and charge it.

Or, if a battery has gone totally flat, it may pulse the battery with a higher voltage, to try and recover it- if you have a battery that refuses to charge, try pressing the button!

Hmmmm, been about this price for pretty much ever.

Give them a go then... you have both types, try it!

It is the ability to treat good 2 go types jut as you would disposables though,... I don't need to even think about batteies, they are just "there" and I barely bother with the standard ones I have, unless I run out of the smaller number of LSD type!

They are even more vociferous than that!

The only greater madness I see is the tungsten filament bulb brigade. With them, it is some sort of panic at the loss of those bulbs, made to seem about as significant as the loss of a limb! Common sense just gets thrown out of the window, fantasy gets brought in, and suddenly various pretend illnesses are made up a a reason why they can't use low energy lighting, when in many cases, there is even IMPROVEMENT for those with sight problems with Low Energy lighting!

The Daily Mail has a lot to answer for for that, and thankfully there hasn't been such an obsessional attack against rechargeable batteries!

Which is precisely why MOST uses and users will find the LSD type so convenient - they won't have to worry,and just use them, whether tit is in a shower radio, remote control, clock, or a torch or camera flash, they ARE designed for use pretty much everywhere.

I think if I was using them in such critical situations as you suggest, I would do some simple testing to find if I there is benefit either way, but for the average home user, the LSD type means it is like using disposables, you just stick them in and they are there!

Ah, the mythical Camlink charger ;-)

I've been looking for one of these for a while. I've visited 6 different Home Bargain stores on my various travels and have yet to find oen. Plenty of hens teeth, glass hammers and chocolate ifreguards but not chargers. :-D

And on the light bulb issue I too dislike energy saving ones due to them needing 10 minutes to warm up.

The future is energy saving, the future is dimly lit.

I currently have engergiser batters which I bought a year ago or some but need to buy some more AA batteries. Are these batteries better than the current Engergiser ones I have and if so I presume I would be able to use my Energiser charger for them and it would be just as good. Please help.

Narkodrom, here is a review from the good 2 go batteries:

I thought I would do a test between the AA versions of Sanyo Eneloop, Panasonic Infinium and the 7 Day Good To Go Batteries,I charged 4 of each in the same charger until it showed them to be fully charged,they all indicated 100% charge on my Annsman battery tester I then left them for 2 months and measured them again,the Eneloop and Good to Go still measured 100% the Panasonic only 80%.In my opinion the Good to Go are every bit as good as the Eneloop but at about half the price.

7dayshop.c-om Reply. Wow what a great review. A big thank you for taking the time to run such a useful comparison, we are delighted that our Good to Go batteries have come out so well !

A few 7 dayshop items lately have been cheaper on Amazon Marketplace. Odd, you would expect them to be making even less, what with fees from Amazon to pay.

That said, the Good 2 Go low self discharge ones are still cheaper than any of these, and most people will still find them no compromise over the nominally higher capacity standard ones for most day to day use.
