So do I. They rarely last more than a year before they leak, and some
brands even less. Before they changed from some anonymous Chinese
manufacturer to GPT, the Office Depot brand sold here lasted 3-4 months.

An awful lot of the 'Duracells' you'll find in discount places,
markets, etc. are chinese fakes. A genuine Procell PP3 has six
cylindrical cells which look like a small AAA cell. The ripoffs I`ve
seen have flat cells. You can barely tell the difference from external
appearances alone - the price should be your guide.

I've never bought any at a market, as they are cheaper in bulk from places like Rapid Electronics.

It may have been Farnell (same company as CPC) I got them from. I use both Farnell and Rapid, whichever is cheaper. Rapid are good for NiMH.

There are 1.5 volt lithium batteries, such as AA's. They are rare,
and have extremely long shelf life, but I have never seen specs
for discharge rate, etc.

Eveready sells litium 1.5V AAs. They're most-commonly available in camera
stores. They have two or three times the capacity of your ordinary alkaline,
I believe, particularly in high-drain applications.

CPC are my usual source though on Friday, I bought 2x4AA rechargeable from
Aldi because, I needed some in a hurry, I was in Aldi, the last ones I
bought there seemed OK, CPC postage makes them expensive and I just
received my last order from CPC (around 300 pounds) and wasn't expecting
to place another order "soon".

One set charged up fine but one cell in the other set won't take charge.

Lame. I keep hearing this silly excuse. This is consumer high-street
shop level thinking. The whole audio industry is riddled with it. For
decades dull black boxes have been shifted with the letters PRO on
them, regardless of how tacky they are, never has an industry blown its
trumpet so loudly.

Err, we're talking radio mics here. And pro ones are in a different league
to the low end stuff. They have to be rugged - and possible to fix if
damaged.

Do they use alkalines in space?

That's a stupid comparison - you'd have to take all those needed with you.
Plus the fact that 'space' has easy and constant access to a source of
power - the sun. Unheard of in the UK. ;-)

In oil drilling gear that has to go down deep in the earth and stand
vibrations?

They use PP3s there? Or AAs? AAAs?

In pacemakers?

Cost almost certainly doesn't matter there.

In aircraft black boxes?

Any battery used in that will be a backup.

Ok, maybe they do, sometimes, but there are lot of battery technologies
reached for when mission critical reliability is needed, and I bet most
industries don't reach for alkalines.

Their requirements are likely different. With radio mics you need a
cost/performance/reliability compromise.

Oil wells reach for lithium thionyl chloride, for
example. If long life primaries with extreme reliability are important
to people who are so up themselves with their 'reputation' and their
expensive hours that are worth SO many batteries, why not buy those?

I can give a reason. Very high capacity (and cost) primary cells might be
ok where you can log the usage. Unfortunately in the film etc world this
isn't always possible - one person might be looking after dozens of the
things. So fitting brand new ones with a reasonable life is simply more
convenient - you change them all at natural break times. That might be
once a day - or twice. With some, three times. Most give a life of at
least 5 hours.

Instead of clinging to one aging method that is highly polluting, use
some imagination and explore what REAL professionals with mission
critical requirements are up to. Compared to those, the industry that
makes such a song and dance of putting microphones in front of
delegates at conferences is like the hairdressers and telephone
sanitisers that Douglas Adams whimsically crashlanded on some planet
along with a captain with a penchant for bathtubs and rubber ducks. >
While we need entertainment and communication to make life worth
living, people used to get by till very recently without having to use
so many mics to feel important or get themselves heard.

Thanks for showing you don't have any understanding of this industry.

Think I met you once in the form of a large middle aged lady. I was
working on a live TV current affairs program. Went to clip a mic on her
and she said 'I don't need that, I have a perfectly good voice'

Get a grip. This thread has wound its way round this silly circle for
too long, and I should never have got into it myself, but I have, and
this is my parting shot. I'll read the flames if I have the patience,
but I will try not to get further involved.

It's as well to understand the problems in an individual industry before
trying to apply fixes from another. TV is full of kids just out of college
trying to do just that - and failing miserably. I've seen hundreds come
and go...

I admit to using a few alkalines at times, but either where laziness is
more attractive than performance, or where nothing else fits yet. If I
could change all to Li-ion or lithium thionyl chloride types, I would.
Specifically, the only time I justify an alkaline is when I need a PP3
that is ready to use, between long periods of disuse. For anything
else, I find another way.

One of the most important things with some RMs is size - if they have to
be concealed on the body. Better batteries allow smaller units. But good
RMs are extremely expensive and none will junk good ones just for this.

I would have told her that the audience was miles away, and her voice
wouldn't carry that far. Then I would hint that I would have the Cyron
operator put up a message that she had refused to use a microphone
because 'I don't need that, I have a perfectly good voice' and see how
fast she changed her mind.

I had one of the power supply boards in a RCA TK 46 studio camera
start to fail while on air. I was in the process of rebuilding every
board of that type and had just finished one so I slipped into the rear
door of the studio & got that camera operator's attention. He used his
intercom headset to inform the control room & director so I could repair
the camera between shots. I had just finished when the preacher on
camera called out to me to join him in singing some southern gospel, on
live TV. I politely refused, because my singing voice is registered as a
lethal weapon.

Are those times for cells that have been stored in unused condition,
or for cells that are in a device which is in occasional use?

I believe that the former (shelf life when fully charged) is often a
good deal better than the latter (lifetime once partially discharged).
I've read that even a modest partial discharge of an alkaline cell
starts an electrochemical reaction that can lead to corrosion of the
case after a year or so.

I think it has more to do with who makes the batteries and where
than how they are stored. We get lots of things from Hong Kong,
Singapore and mainland China.

If you think the people who put melanine in powdered milk, or used lead
paint on toys are the only ones who produce cheap junk and label it
has high priced well known brands, you are mistaken.

Here, were most UK and US brands are not officially sold, and grey market
goods are perfectly legal, you never know what you are buying, even if you
buy it in a well known store.

I expect that it's now the same way elsewhere, except that the name
brands usually are really what you think you are getting.

For example, last Christmas one of the major UK retailers sold a DVD player
for 10 quid. In the box was a remote and I assume batteries. How much did
those batteries cost, and how many of them surfaced with "brand names" on
them?

I'm in the US, so quid is meaningless to me. Most remotes here seem
to be shipped with crappy carbon zinc, or no name alkaline cells. Some
are so bad they leak before the item is sold.

Right now you can buy a DVD player for US $14 after a $5 rebate. I
saw plenty of them in the 19 to 29 dollar range through the year.

I buy only name brand US made cells when I can. I keep a good
supply on hand for power outages, flashlights & hurricane season. I use
my oldest stock between seasons, and some got quite old. They were well
past the use by dates, but all were still good.

Same in an Energizer, the difference is that the cells in a Procell
are connected by spotwelded on flat metal strips
In an Energizer, pressure alone connects the cells to the top terminals
and bottom conductors. That might explain why they sometimes
inexplicably fail after a few minutes.

In an industry where possibly 40 or 50, radio packs may be used nightly

they could get away with using rechargables and saving money?
