Dont bother with these type of batteries in anything that you dont charge regularly (Especially smoke alarms, remote burglar alarms, etc)

For that you need to buy this type: http://www.hotukdeals.com/deals/8-x-nimh-rechargeable-low-discharge-stay-ready-batteries-10-50-vapextech/952263


These vapex batteries are exceptional if like me you like your batteries ready when you're ready for them!! I'm switching from std nimh over to these long life versions.

Couldnt agree more.

Great deal if they were decent these cheap ones don't hold a very long charge as you will find out. I used to use them in mw Wii-Motes but they lasted less than a day sometimes. I switched to £1 for 10 battterys from my local pound store which last a lot longer (Kodak :)) Plus the fact you gotta charge for 7 hours for about 3-4 hours use?? Is it really worth the hassle?

These are only useful if you have high drain electronics, like digital cameras, radio controlled cars, etc. Don't buy these if you're planning to put them in remotes, small digital clocks etc; while they will work, the voltage will drop fast. The only reason the person on page 1 still hasn't had to charge their batteries in their remote is because remotes don't require that much power in the first place, even batteries that are almost dead can power them, that doesn't mean his batteries haven't lost most of their voltage due to the nature of standard NiMH batteries.

Instead of buying a 20 pack, buy some low-self-discharge NiMH batteries like Hybrios, Eneloop etc. 4 x AA Hybrios can be bought for £5 and in non-high drain appliances will outlast these 2900mahs easily due to the fact that they hold their power for longer. Hybrios last ages in WiiMotes.

Using any kind rechargeable batteries in smoke alarms let alone standard NiMH AA's is very dangerous. 9 volt Hybrio/Eneloop you can maybe get away with, but smoke alarms are the one place you should put a good quality alkaline (Energizer's are good) or even 9v lithium (again, Energizer sell them).

I use duracell rechargeables in my wiimotes, the lifetime is measured in weeks rather than hours. Although I also use those Kodak ones for other things, they're better 'per pound' than Duracell standard.

great deal heat added but who needs this many rechargeables ?oO
people with remote controls, bike lights, smoke alarms, etc etc!

bit of a silly comment really!

"Silly comments" here's a very silly one......

"people with remote controls, bike lights, smoke alarms, etc etc!"

Using rechargeables in a smoke alarm is a definite no no(unless they are the Eneloop type) they're also not that great in remote controls.
.....and smoke alarms warn you when the battery gets low! DOH!

I have seen it commented that using rechargeables in a smoke alarm can be risky as the pace at which they lose charge could prevent the warning being picked up apon - e.g if you were out a day for example by the time you returned the batteries may not be strong enough to have continued with the audibile warning . Not sure how true this is though.

utter crap as per usual!

I have some in my Logitech universal remote and havent had to recharge even after 6 months use.

and smoke alarms warn you when the battery gets low! DOH!



The only rechargeables that have been any use for me in remote controls have been the 'eneloop' type. Most 20 for a quid batteries I've put in a remote have lasted the best part of a year, where the rechargeables usually need replacing after a month or two.

And please don't ask folks to risk their lives putting the wrong types of batteries in their smoke detectors!!!

The deal is no good for me as my charger will only take 4 AAs at a time ;)

This is an interesting read. http://e-group.uk.net/forum/showthread.php?t=12087 . It basically backs up completely what you have said and i am now wondering why i keep buying 7dayshop good to go instead X)

I already have 24 AA and 8 AAA, I could still do with a few more AAs, Remotes, Wii controllers, RC Toys, Wireless mouse, X box 360 controllers, Childrens toys..

I need about 40 AAs so getting these too
#55
Forgive me for saying so but if you buy 5 or more individual packs don't you get them for £3.99 each anyway - whilst the 5 pack is a good price i'm not sure that it's a particularly good "Deal"
#56
I just noticed the 'good to go' are the same price - I've not used 7dayshop batteries and I know the 'good to go' aren't the best of their type; but they might be better suited for items that aren't continually in use.
#57
Ni-Mh self discharge, so they're going to go flat in your remote quicker than normal ones.

Then they specify "up to 1000 recharge cycles" (or whatever). They don't specify that "UP TO 1000 cycles" could mean "DOWN TO as little as 5 recharge cycles before this battery becomes almost useless". There's no guarantee for minimum number of cycles (usually).

I've not tried this brand and have no plan to do so, as all previous efforts with cheap rechargeables have had very poor results and even branded Sony ones have been a major let down.

I'm currently evaluating Eneloop batteries. For a start, they hold their charge well. I'll report on life in about 3 years time, but right now it seems like these are the way to go.

My original (HR-xUTG) AA's and AAA have been in use since September 2007, still doing well as they should, haven't been cycle counting though. No better than cheap NiMHs in medium or high discharge devices but they serve their purpose well for less demanding stuff and longish term storing.
