Duracell think that they are so good they don't even need to tell you what capacity the batteries are. I fell for this a couple of weeks ago when I bought their 'D' cells from Tesco Direct and they turned out to be 2200 mAh which is only at the top end of the range for double A's.
#2
Not bad price - what mAh are they then?


got it - 800's.

Put Duracell on it, and it's hot! Hmm... maybe, but you can do better for the money, there is nothing very special about Duracell, it's all about advertising :-(

WAY behind other companies, they have at long last put out a range of Low Self Discharge batteries :
http://www1.duracell.com/uk/products-detail-activecharge.aspx
2000mah, for AAs (not 2200mah) normal enough for this type, which holds it's charge. (AAAs are 800mah)

Currently, the Good to Go range from 7 dayshop are the best value in this type of battery, (2100mah AA capacity, 800mah AAA) and are £3.99 for 4 or less:
http://www.7dayshop.com/catalog/product_info.php?cPath=777_3&products_id=107341 for AAs
http://www.7dayshop.com/catalog/product_info.php?products_id=107340&PHPSESSID=4cfb26d08d6534151d81edc833c7e625 for AAAs

They turn out to be 800mAh. You can buy their 1000mAh ones from 7dayshop for £4.80 delivered

No, NOT the same type, the Good to Go ones are cheaper too, and although nominally smaller capacity, are more versatile, and as convenient as a disposable so generally less bother.

There are some suggestions on the web that Duracell Active Charge are in fact eneloops (as they are both made by Sanyo). If so this is a good price.

Eneloops are still generally recognised as being superior to Good to Go and other cheaper LSD batteries in applications where high voltage is required by the equipment; in all other uses from the reviews and comparisons I've seen there isn't any benefit from the more expensive eneloops.

Rumour, nothing more.

Yep - it's hard to find any real evidence - it all seems a mess with some of Duracells operations having been bought by GP; Panasonic having a controlling interest in Sanyo and some of Sanyo battery having been sold off to appease the regulators...

The simple fact is all the LSD batteries I've tried; Hybrio, Kodak and Good to Go have worked well (better than much higher rated nimhs) - the Hybrio have performed well over more than a year (haven't had the others long enough to say).

yes, D rechargeables just have a single AA inside them now, just a plastic shell around it

2200 is pretty good for what are low self disharge for aa, and 800 for aaa

i guess duracell have been the last to make this technology seeing as they rely on us chucking tons of expensive batteries away for decades

LSD batteries for me spell the end of paying 2.50 for 4 alky duracells, and the end of the disposable forever

I don't know about this either.I have stuff that will NOT work on anything under the "stated" 1.25 v which as I understand it rechargeables don't have that capacity :thinking:
BTW 1 piece of "gear" uses 8 AAA's so the voltage drop across the 8 is fairly significant in the scheme of things is it not?

so which batteries is it your recommend right now value for money wise and quality? when i clicked on the 7 day shop i had to login or sign up?

i'm looking to buy 4 aaa and 4 aa's both sets rechargeable.

either delivered or pick up any shop

For about 18months i have used panasonic infinium, bought from 7 days shop, so far they have lived up to their claims, one set is unused and just the other day, got it out of the pack (18 months!) and it still had plenty of original charge to fire up my canon camera, made a few shots, they dont need recharging yet

but looks like they cost a couple of quid more at 7 days shop than these!

I don't doubt that as I'm not an electical engineer; but would you care to explain why voltage has no relevance here as you are clearly more knowledgeable than me?
Comparison tests I've seen imply that the eneloops deliver a slightly higher voltage and voltage sensitive devices (Pentax DSLRs are quoted as one example) will show low charge and shut down on makes that don't deliver or hold that higher voltage.

Thanks for that support - have some rep :-D
(I hate it on this site when people make sarky comments with no basis or explanation).

Some samsung camera's in the menu have a selection for rechargeable or alkaline because of the voltage issue

nimh are almost stable voltage to the end, but start lower
alkys start higher and drop lower as they get used up

Is there a special (or preferred) type of charger for low discharge batteries?

Simplistic no-load terminal voltage measurements tell you nothing about battery performance. LSD batteries have a marginally lower internal resistance than standard NiMH batteries so may show a few tens of millivolts greater terminal voltage, but this of no significance when the device is in use. What is useful, and relevant, is the ability of the battery to maintain a steady average voltage throughout the discharge cycle of the battery, but this has no direct correlation with having the highest terminal voltage.

No problem with most chargers, probably better not to rapid charge them, but as they hold their charge, if you have enough spares, you are not likely to need fast charger anyway, as the ones you last charged will probably still be perfectly ready to use!
Something around a couple of hours+ will do fine.

I can't recall having used the phrase "highest terminal voltage" or "no load terminal voltage". Yes I didn't know what I was talking about but what I initially said was correct; as the tests I had seen showed the eneloops maintaining a higher voltage through the dischgarge cycle than some other types. Rather than your pointless sarky comment you could have instead used your knowledge to correct my simplistic use of 'higher voltage'.

Thanks for being such a help. (Yes that was a sarky comment) ;-)

Data please.

Data please.


I can't supply data - we've already established my electrical skills and I don't own any sanyo eneloop.
I couldn't find the HUKD threads where this has been discussed and from where I formed my sweeping opinions; but I'm pretty sure this was one of the articles referred to http://www.candlepowerforums.com/vb/showthread.php?t=223842&highlight=Recyko

On reflection if you'd initially asked for evidence to back up my statement rather than highlighting "high voltage" you'd have received an apology rather than a grumpy reply :oops:

I'd still maintain that from what I've read and opinions expressed by others Sanyo Eneloop may be worth the extra money in cases where a higher discharge voltage through the powercycle is required.
