How To Choose Batteries and Store Them
Strabo
Choose the right battery.
There are many types. Find your application and buy wisely.
http://www.mpoweruk.com/battery_types.htm
http://www.batteries4less.com/contents/Battery_Guide/
For 'D' 'C' 'AA' 'AAA'
1. Some brands are manufactured with quality materials and to higher
standards than others.
2. Every manufacturer tests batteries individually or by batch.
Those that are below standard are sold to resellers for discount
distribution while those that pass get the brand name.
3. Quality batteries have manufacture and/or 'use by' dates.
As a rule of thumb, cheap batteries are cheap for a reason.
Before installing batteries wipe each with a clean absorbent cloth or
paper to remove oils and moisture.
Inspect battery compartments, contacts and leads for moisture and
corrosion.
To maximize battery life keep batteries clean, dry and cool.
For intact commercial packs, keep them in their commercial wrapper
and store in a refrigerator between 40 and 50 degrees.
If a device is not going to be used for a month remove the
batteries and place them in container in a way that the battery
nodes can not make contact and attach to the device, or, store
them in a refrigerator as described above.

Do not consider "Heavy Duty" or similar names, they're carbon-zinc. You
don't want them.
"UltraLast" doesn't.
Energizer and Duracell alkalines give similar performance.
Ray-O-Vac alkalines have about 20% less energy than Energizer and
Duracell.
Keep'm in the freezer and they'll be fine in 2 decades.

More primitive technology. Ray-O-Vac didn't keep up. Duracell pioneered
mass production of alkalines but Energizer caught up. Both are head and
shoulders above the other brands.

For instance Fujitsu: http://www.fdk.com/ says diddly squat about their
electrical specifications even though they are a high volume, world-wide
brand. Same for Maxell, Sanyo and Hitachi. Guess I'll have to take the
time to run discharge tests and compare...
Varta, German, does offer their data sheets. The specs are about 10%
lower in capacity than Duracell and EverReady but this might be due to
advertising creep. I'd have to do a comparison test in order to believe.

Ive got an alkaline ReZap charger from Schlemmer and the Energizers charge
good, but the Duracells leak if i try and charge them . I put a quick charge
on them for about 5 minutes to load pictures of my camera ,and they didnt
leak but i dont trust them . The problem is they dont leak while charging.
They leak later when you have them in something. Many people stated the
same and i got the same results. But other then that i love duracells.

You're cooking the core. The fast charge is damaging the battery.
Are alkaline batteries designed to be recharged?

CY: Carbon zinc cells tend to go dead, on the shelf, in a
couple years. Alkalines last a lot longer. Also in devices,
I have tested years ago, and find alkaline battery is equal
to four carbon batteries.

If the cell is discharged too much, it will leak after
charging. Usually several days later. I put the batteries
aside for a week or two. Check them later for leaks (always
around the negative end) and if it's still charged.

I've been tossing perfectly good incandescent flashlights whose
batteries will not hold a charge in favor of the new LED's.
In fact, I've taken "dead batteries" out of incandescents that work fine
in LED's.
Curly Surmudgeon
Some but those are identified as "ReChargable" and use a slightly
different technology. In my experience you can recharge Alkalines for
low drain applications with a slow charge. I used to charge Duracells at
about 20 ma overnight with absolutely no problem.
Now I just buy mass quantities and store them in the deep freezer. Even
10 years past expiration they perform well. Remember this rule of thumb,
chemical reactions half/double every 10 degrees centigrade. That's 18
degrees farenheit. If you store them at -20 degrees then you've extended
their lives by roughly five.

Yup. The inverter in DC to flourescent lights is actually an inductive
flyback converter which requires a low ESR, a current surge. Batteries
that fail there will work just fine, for a long time, in low drain
applications.

That's not the best part. Best part is the magic glasses that con man
Joseph Smith supposedly found magically that allowed him to translate
these ancient Hebrew texts he supposedly found. Then, of course, an
angel came down from Heaven and removed said tablets and magic glasses
and conveniently whisked all the evidence away to Heaven. Damn it, I
hate it when angels do that. And these moron Mormons buy it all.
And if you want to know what they will do to people that cross them,
google "Mountain Meadow Massacre", "blood atonement", and the
subsequent cover up. Without a doubt one of the most bizarre,
illogical, and corrupt religions ever devised by insane people.

Heat does indeed accelerate molecular activity. And removing molecular

However, I welcome demonstrable evidence concerning freezing batteries.
I'm sure the type of battery is important. Not all will respond in

In the past, I don't believe that I noticed any substantial
differences in capacities between various brands.
IIRC, Consumer Reports had noted that the capacities for various
alkaline batteries were all quite comparable (even store brands).
Where I see a difference in performance is on the leakage issue. If
you're going to store batteries in a device, get good quality (i.e.
Duracell in all of mine). For day-to-day use, use whatever is cheap.
And, of course, rotate your stock.
Of course, if the device doesn't need batteries stored in it for your
use, then don't store the batteries in it.

and then open with Adobe. Wouldn't open in Firefox. Yeah,
you can't upgrade very far, when you run Windows 1972.
In the past, I don't believe that I noticed any substantial
differences in capacities between various brands.
CY: I havn't noticed capacity diff. Some over aged cells got
cheap, and leaked.
IIRC, Consumer Reports had noted that the capacities for
various
alkaline batteries were all quite comparable (even store
brands).
CY: That's my memory. all about the same.
Where I see a difference in performance is on the leakage
issue. If
you're going to store batteries in a device, get good
quality (i.e.
Duracell in all of mine). For day-to-day use, use whatever
is cheap.
And, of course, rotate your stock.
CY: I'm with you. I've heard good things about Energizer.
Of course, if the device doesn't need batteries stored in it
for your
use, then don't store the batteries in it.
CY: some things, it's nice to store with batteries. Tool box
flashlight, for example.

I use rechargeables in my daily use items, but prefer primary cells
for emergency-ready devices like radios and flashlights -- many/most
rechargeable batteries lose charge, and are dead when you most need
them. Other devices are stored without batteries.

Is there a formula, to know how many batteries to store at
home? Set in the device, plus two more change of batteries?

Rechargeable batteries aren't "primary cells" in the Mor(m)on dictionary?

Ray-o-vac alkalines specification sheets show a lower energy capacity
than Energizer or Duracell. Someone here posted the opposite for D
cells. Work on that reading comprehension problem.

I thought this was obvious, but apparently not...

No they don't. They look quite similar.
Rayovac's page has all cells together:
http://www.rayovac.com/technical/pdfs/pg_battery.pdf
These are the AA:
http://data.energizer.com/PDFs/E91.pdf
http://www1.duracell.com/procell/pdf/MN1500_US_CT.pdf
Picking a rational load, say 200 mA, all three brands of AA batteries
have about 10 hours service life (running down to cell voltage 0.9 V)
These are the D:
http://data.energizer.com/PDFs/E95.pdf
http://www1.duracell.com/procell/pdf/MN1300_US_CT.pdf
Picking a rational load of 0.5 Amps, the Rayovac and Energizer both
have a service life of about 20 hours, the Duracell appears to have
about 25 hours.
The Duracell D stands out from the other brands. The Duracell AA does
not. And the Energizer and Rayovac are the same.
(all assuming that we can believe their engineering data)

How about you pick a shelf life (say, limit it to 3 years), and then
figure out how many batteries you use per year.
Note: Energizer says 7 year shelf life, stored at 21C, with 80%
retained energy.
Stock up to the level that you won't be using batteries older than 3
years in storage (i.e. when you use them, the date code should show
3-4 years left -- so check your date codes when you buy them, also).
Once at that stock level, buy a 1/2-year's worth every 6 months, and
use FIFO (first-in, first-out) rotation. (3 years worth of batteries
might be a lot of storage, so maybe you want to trim that down...)
Don't forget to rotate the batteries sitting in your emergency devices
out every 6 months or so (and cycle those batteries through your daily
use devices).
But if you're going to do it this way, I would suggest you quit buying
crappy discount batteries... Leakage is likely to wreck your devices
(and I've had some cheap store brands that leaked in the forgotten
package, stashed where they didn't get FIFO-ed).
BTW, you could do the same thing with canned foods, etc. In this case
you may not get a lot of "shelf life" buffer, so try to buy them in
quantites that you can use by the date code -- generally the code just
means "best buy", since they probably won't spoil unless the can is
breached. After this date, texture and flavor may degrade -- vitamins
start to degrade from the time they're canned, so plan to supplement
vitamins elsewhere. Those rules are not true of the plastic packaging
materials -- oxygen transmission occurs much faster in them, so be
sure to eat them by the "use by" date (or you could have rancid,
off-flavor food)...

How about you pick a shelf life (say, limit it to 3 years),
and then
figure out how many batteries you use per year.
CY: Ah, but that's the problem. For the last some years, I
keep expecting the world to get worse. As of the year 2009,
I've used mostly rechargable AA. Then, a few AAA cells in
flash lights. Couple of button cells, some hearing aid
batteries, and I can't remember if I've used any C or D
cells.
CY: But, when things get worse, I'll be giving away some
flash lights (really!) and would be nice to have batteries
to give away. So, I'll be wishing for lot more AAA cells for
the free lights from Harbor Freight. I may also be using my
battery fan (eight D cells) and my various Mag lights. The
fluorescent lantern that uses four D cells. The table top
fan that needs two D cells. Suppose I set up a couple of the
neighbors with FRS walkies. I remember the time I was
working at the museum, and went through three AA cells per
walkie, eight walkies, and they got a change of batteries
every night. Some of my FRS sets are 3AA, and some are 3AAA,
and a couple of them are 4AAA cells.
Note: Energizer says 7 year shelf life, stored at 21C, with
80%
retained energy.
Stock up to the level that you won't be using batteries
older than 3
years in storage (i.e. when you use them, the date code

them, also).
Once at that stock level, buy a 1/2-year's worth every 6
months, and
use FIFO (first-in, first-out) rotation. (3 years worth of
batteries
might be a lot of storage, so maybe you want to trim that
down...)
CY: At my peace time consumption, my battey consumption
would fit neatly in a shoe box.
Don't forget to rotate the batteries sitting in your
emergency devices
out every 6 months or so (and cycle those batteries through
your daily
use devices).
CY: yes, you're right. I've got to make some kind of list of
where the devices are.
But if you're going to do it this way, I would suggest you
quit buying
crappy discount batteries... Leakage is likely to wreck
your devices
(and I've had some cheap store brands that leaked in the
forgotten
package, stashed where they didn't get FIFO-ed).
CY: I have also had batteries leak, new in the package. And
some that leaked in flash lights. So, I'm learning to keep a
couple devices with good batteries, and keep the crappy
quality cells for the moment I'm about to need the light,
and then take the batteries out later.
BTW, you could do the same thing with canned foods, etc. In
this case
you may not get a lot of "shelf life" buffer, so try to buy

so be
sure to eat them by the "use by" date (or you could have
rancid,
off-flavor food)...
CY: yes, that system would also work nicely for canned
foods.

It's that comprehension problem thing. Curly should buy some, but it
may not be available locally in Argentina.
