We've been using 7day shop rechargeable AA's in Braun Oral B

1. They are slightly overlong (maybe half mm) and require a lot of force
to close the snap-shut cap. Is this typical of rechargeables or is it a
prob only with 7Day shop batteries? Have cracked cap one one Braun
already.

It's a problem of substandard batteries. None of mine have ever had this
problem.


2. They don't last very long - maybe 2 weeks. They can last 12 months in
a wall clock but struggle with high drain stuff.
The perfect answer is Duracell but these are not cheap. I've tried
Googling for an alternative but you get pages of Amazon spam.

Eneloop Pro NiMH have pretty high energy densities. I've had some but
not long enough to given an honest opinion.

Q. Can anyone suggest an alterative disposable brand please - of
reasonably good quality. TIA.

Bulk packs of Energisers from CPC can be had at excellent/unit value.

Babz on eBay also have a good range of suppliers, pack sizes, and
battery types. Quick and good prices. No connection, just my usual
"first stop".

Duracell can be cheap...

http://www.battery-force.co.uk/category-BESTSELLER.html

though, it does say 'industrial'? I know not what that entails.

How is that cheap?

30 for £12 inc VAT = 2.5 batteries for £1 (40p ea) compared with
Poundland -
6 for £1 (16.66P ea) or Ikea - 10 for £1 (10p ea) ...

It's a bit like comparing chalk with cheese. It's difficult to judge
hi-drain batteries with low-drain. 10p per battery sounds cheap but in my
earlier post, you'll see that the batteries from the 99p shop only lasted 5
days in my Oral B toothbrush (4 days in wife's OB). So the cost is 2p per
day.

My 5 year old OB died in July, I ordered new from Ebay, it came supplied
with Duracells. It's been going strong since 23rd July. Lets assume they
last another week or so. 40p per Duracell for 80 days = half p per day.
Therefore a quarter of the price of the "cheapo's". Agreed the budget brand
bats a fine in lo-drain wall clocks etc but hopeless (cost-wise) on the
hi-drain gadgets.

If the ordered Eneloop re-chargeables fit the Brauns ok, I won't need to buy
disposable batteries again - neither Duracells nor cheapo's.

Its not news that zinc chlorides are low on capacity and high on price per Ah. No-one that understands batteries would rush to recommend them, other than in exceptional cases.

Not really as it's down to internal resistance of teh cell, if that is higher
then you can;t have a high current drain so the battery may well last longer.
This is why those small coincells can last years in PCs becusea all they do it keep teh clock circit and low power memory 'awake' Those bats are typically 3V at 250ma and they can last for 5+ years.

You might put it like that. I'd not.

There is so much variation in battery prices - and quality - that it's not
easy to say what you should go out to buy for best value. My local 99p
shop was selling single PP3 Panasonic carbon for that 'quid' - hardly good
value.

Personally, I buy disposable batteries at Lidl.

Actually it's not so hard. Rechargeables where they're practical, and whatever brand is cheapest alkalines otherwise. There just isn't enough difference between brands in 99% of cases to justify paying differing prices.

ZnC and ZnCl are consistently poor contenders.

The most you can really say is that if you have some stuff
that does usefully use alkalines, it does make sense to use
those in clocks once they wont power the higher load
devices anymore.

But if you don't, it makes a lot more sense
to use lower priced zinc batterys that don't
leak in the lower load devices like clocks.

I've certainly seen alkalines which have leaked. Of course since I used
more of them than zinc, not possible to say which is more likely.

But with something like a clock I'd assume you'd replace the battery when
it stops working. So not much chance of a leak, which is far more likely
in something left unused for a very long time. In which case you should
remove the batteries anyway.

me too that's why I say less likely as that is what I have found after using Zn for a few years in our clocks.

not unless you've made a mental note of them or had people bring back used batteries like they do here. (4 alkaline today so far) last year I recyled 80+KG although two were lead acid mobility batts.

I have 20 of 4XAA battery holders behind me ready for fridays lab.
I have about 20 AAs with less than 80% 40% remaining charge for general purpose use. I have 20 alkaline battereies ready to go out on my next order tomorrow.

I have ~40 alkaline PP3s for another lab later this year.
I have ~40 NiMH AA mostly fully charged also in 4 way holders.

But with something like a clock I'd assume you'd replace the battery when
it stops working.

That's the general idea.

All the main chemistries leak, including NiCd & NiMH. ZnC & its ZnCl variant are unique in having many times the leakage rate of the others.

On the contrary, when ZnC die is typically when you find out they've leaked. And a long slow discharge to a low end voltage, as is normal with clocks, increases the risk a good bit. Clocks are thus a lousy app for ZnC.

well I only have two in my lab which aroung 100 ft in lengh, both radio clocks
which set themselves. They are about 4 mins apart but good enough for the use we put them too, sometimes you'll here them reseting themselves, other times I have to take the battery out and refit it, so it does reset itself after the clocks change.
Over the years I found that Zn leaked almost regually whereas the alkaline ones rarely leak and when they do don't leave a sticky residue like the zn do meaning I have to ditch the clock.
both alkaline an NIMH produce an almost fungus like white dust on the terminals and sometimes the case.
I also keep a few lipos haven't had one leak yet but they do appear to buldge out, especaily after student use.

Bought a pack of Tesco finest zinc specifically for clocks. Non has leaked.

And I've never had any leak unless left on in something you'd switch off -
or very old. Neither of which is going to apply to a clock here.

Low power LCD clocks tend to be exactly the sort of thing where the
battery life is longer than it would be if left on the shelf. The snag
is that the battery will be run into the ground before the display fades
out and they do sometimes leak before the juice runs out. Pun intended.

I have a stock of no longer any good for high current duty primary cells
that serve the rest of their life in my phone for its LCD display or one
of the various domestic clocks. Where possible I use NiMH but some low
current devices won't work on the lower voltage.

No point in using alkalines in clocks.

Yes there is, they are far less likely to leak than the Zn ones are.

I've certainly seen alkalines which have leaked. Of course since I used
more of them than zinc, not possible to say which is more likely.

All the main chemistries leak, including NiCd & NiMH.

ZnC & its ZnCl variant are unique in having many times the leakage rate of
the others.

Bull**** with the best of them, particularly with stuff
like clocks where even someone as stupid as you will
usually notice when its stops and change the battery.

But with something like a clock I'd assume you'd replace the
battery when it stops working. So not much chance of a leak,
which is far more likely in something left unused for a very long
time. In which case you should remove the batteries anyway.

On the contrary, when ZnC die is typically
when you find out they've leaked.

Even sillier and more pig ignorant than you usually manage.

Never had that happen with a clock.

And a long slow discharge to a low end voltage, as
is normal with clocks, increases the risk a good bit.

Even sillier and more pig ignorant than you usually manage.

Never had that happen with a clock.

Clocks are thus a lousy app for ZnC.

I'd have you publicly flogged if you hadn't
enjoyed that so much the last time.

But plenty don’t anymore. The only high current
duty devices I have anymore is the Culinane Jar
Opener and I use Eneloops in those and it
makes not sense to use those in clocks.

Where possible I use NiMH but some low current devices won't work on the
lower voltage.

Those aren't suitable for clocks because of
the much higher self discharge those have.
It makes much more sense to use zinc cells
that don’t leak in clocks if you don’t have
any high current devices you use alkalines
in and put those in clocks when they no
longer work in the high current devices.

it's an option but hardly worth the effort in my case.
I have to keep enough batteries as it is.

You may be correct, I've got two disposable and two 7day rechargeables
(now dead) that need to be re-cycled. I've also got two Energizers. The
latter is fully discharged, so therefore safe to use with micrometer.

'Performance' disposable (99p Shop) = 50.00mm
'Energizer' re-chargeable = 50.10mm
7Day Shop re-chargeable = 50.30mm

As you say, the rechargeables do seem a touch longer. Let's hope the newly
ordered 'Eneloop' are closer to 50.10 and won't strain cap on the Braun.

Further Googling also suggests that it's also the thickness that presents a
problem :-
http://www.talkbass.com/threads/warn...sized.1129918/

A quick measure shows the following diameters :-

Performance disposables 13.45mm
7Day AND Energizer rechargeables = 14.25mm

There follows one glimmer of hope in bcCopenhagens quote, that Eneloops
conform closer to disposable AAs. Lets hope they mean length and thickness
:-)
http://jwsoundgroup.net/index.php?/t...e-aas-too-big/

Update: The Eneloop rechargeables arrived Wednesday and they do fit the
Braun Oral B's ok.

It's a tight fit but they are shorter than the 7Dayers and are the same size
as my old Energizer rechargeables i.e. 50.10 mm long by 14.25 mm dia.

Thanks again Tim W for recs' on the Eneloops. Early days but there seems to
be plenty of 'oomph' for the hi-drain toothbrushes. If they last the
advertised 2000 re-chargings (2000 months = 166 years) ... I'll have to Will
them to my great grandchildren :-)

I still have no idea why re-chargeable batteries are wider and longer?
