Ni-Mh Rechargeable AA - 2700 mAh £5.19 a pack @ 7dayshop (+Free P&P)

Found 12th Jan 2009Made hot 12th Jan 2009
Been looking for a good buy for a while, these seem an excellent buy and 7 dayshop are great. Also on Amazon for the same price but a long lead time.

Pack of 4 x 2700 mAh ultra high capacity rechargeable AA (LR6) batteries

Found this review on Bristol cameras
- Capacity 2700mAh, 1.25V Ni-MH
- Exceptionally good voltage stability. Under test conditions a voltage of over 1.2V was recorded for 70% of the discharging time.
- Rechargeable up to 600 times. This is equivalent to approx 2400 alkaline batteries for a set of four of these batteries.

Unless you are using them in something like an LED Cree light, then it's all about the mAh.

Leave these batteries in your torch for a month and they'll be flat as a pancake.

My torch uses them up by the hour, no chance of them lasting a month!
(even if I do leave them for a month, there's still charge in them, top them up and they last longer than the 2100's, once these new ones capacity is 2500 I will buy).

What battery charger do you guys use then? Cause I heard the one with the timers are rubbish.

This is not a particularly good deal, especially as it's hard to believe the capacity figures.

i use one of these
batterylogic.co.uk/tec…asp
not cheap but really is the business, can do stuff very few other chargers can do (like refresh batteries and give you the capacity)

edit: this is not actually a great deal, you can get 4x 2900mah good make on ebay for about the same price. but im not allowed to link to them.

Get some hybrio batteries if you want to use them in low drain devices like remotes and keyboards etc.

the best batterys and chargers are Uniross

i use the own brand 7 day shop batteries for my camera - they last ages..
an extra 71p for 4X2800mah on these ones... free case too..

]http//ww…842

are the hybro a brand of battery or a different type of battery?

I am investing in a pile of batteries and a good charger and i want something that is going to be obsolete in 18month
They will be used in console controllers, kids toys and i need some for tv remotes

Any recommendations would be appreciated

Hybrio are hyrbid batteries which are supposed to hold their charge for longer. Uniross have HYBRIO and Panasonic has the Infinium range.

Coincidentally, I bought these AND the Panasonics from 7dayshop and used them both in Cree LED torches. I haven't done a head to head comparison cos I'm not that much of a torch geek but both types of batteries have their own merits.
I'm using a Energizer 15 min recharger with Hybrio and regular NIMHs at the moment with great success.

That's a nice charger! You can set it not to cook your batteries with 200mAh charge :thumbsup:

The ones quoted above are "hybrio" ones.......:thumbsup:

Unless you are recharging your batteries within 2 weeks, you are better of with hybrio et al.
Also vapextech "instant"
sanyo "eneloop"
panasonic "infinium".
They can deliver higher current "amp" which means they can deliver the brightest potential of cree LED torches (for dealextreme fans like me!)
A fully charged 2900mAh AA will only have around 2000mAh of charge left 2 weeks after a charge, even if it has not been used, while the hybrio will still have 50% charge at 12 months.

For a really low power device, like a remote control, you are still better off with cheap alkaline ones, as they will usually only need replacing every few years.

I am using Uniross 2700 mAh ones and they stays months with my Canon S2 IS camera when 2300 mAh could hardly take a week.

As smiff stated often NiMH batteries become 'stale' and a decent battery charger like the technoline can refresh them back into life. That's possibly why your 2300 mAh ones were under performing. Using the above charger my sanyo eneloop ones were only holding 400 mAh until refreshed back up to full capacity.

These aren't 2700mAh even though they are branded such. Energizer 2500mAh's are the top capacity at the moment. These one's certainly won't last as long and will most likely leak :-(

These seem very good so far, giving very fast recycling on my flashgun but I don't yet know how many more flashes I'm going to get compared with cheaper equivalents. The "plastic box" was a bit disappointing, it's really only slightly upgraded packaging.

Sorry, I don't have them I have no idea if they are any good, but from what I hear vapex are a good brand. I have a set of Vapex "instant" low self discharge, and they are decent. The guy that sells 'em is pretty fair too.

That simply goes to show how you can't believe the capacity figures.

Yes, it is interesting how big names like Energizer and Uniross sell max powered batteries of 2500mAh and 2700mAh while some no-name Ebay-seller can sell no-named batteries "officially" rated 2900mAh... Hmmm.

For those interested in detailed measurements of batteries, this guy did it although this is a bit outdated:

Got the batetries through. German made, and hold a hell of a charge.

They look better built than the uniross.

Got mine too, but cheaper 2100 from aldi beat it in terms of charge capacity when I used in my wiiimote cause i needed to recharge these hama ones too often. Not gonna buy anymore of these I'm afraid :(.

An old thread I know, but I ordered these batteries and have tested their capacities in a MH-C9000 charger. The first charge/discharge averaged 2591mAH but after a few cycles I now get extremely close to 2700mAH.

Anyone who says these are pants clearly has never tried them.
