I use old prescription pill bottles to hold spare batteries. The size
I have hold two AA type cells or a 9V type perfectly. The twist on/off
security cap makes a tight seal to protect other items in the satchel
in the event that the batteries were to leak. Sometimes these bottles
stay around a long time if spares are not used very often. In those
cases I'll insert a small paper in the bottle with the date scribbled
on it. When a spare set is deployed the paper is thrown away and the
used batteries can be placed in the same container until they can be
properly added to the collection bucket at the local hardware store.

Does such a thing exist? I did web searches, but maybe my terminology isn't

Thanks,

As Michael pointed out, the same caps that Duracells ship with are
available in aftermarket. Personally, I just use a piece of gaffers
(duct) tape, line the cells up--terminals down, adhesive side up--then
fold the tape down over the sides. That's enough to keep them from
shorting together. Put in a drawer or box, they won't short to anything
else.

YMMV...the goo from the tape is sometimes an issue.

Now if it's AA/AAA/CR123 cells you want to protect, there are nice
little soft plastic snap boxes available that work fine. Dealextreme
sells a set of 3 4-cell AA boxes for < $2.50. Pricey for a few bits of
plastic, but that includes worldwide shipping. I use them for NiMH AA
cells. You often get them for free when you buy a set of 4 cells.

Just out of curiosity, what are you using that requires a 9V
rechargable battery? Something special? Most occasional-use meters and
such like are better off with a 9V primary cell because of the low
self discharge rate of primary cells compared to NiMH.

To be honest, I don't use them for anything. My comments referred to
alkalines used in wireless mics and other sound equipment. I save the
used batteries in the manner suggested above. 9v's are expensive.
While I wouldn't use them again professionally, we change them at almost
every opportunity, since the expense is trivial compared to a dead mic
during a show or presentation. As such, they are still useful for less
demanding applications.

I also wouldn't use rechargables for the application; but the size,
shape and intent are close enough for the method to be useful to the OP.

He is in the convention business. The mics are used to at least half
battery life, per use. Rather than take a chance of one dying before a
second use is over, the battery is replaced. It's figured to be a
consumable item like gaffer's tape & light bulbs.

ProCells are well discounted and often two boxes for the price of one at

When I say they're expensive, I'm speaking as a consumer. A card of two
name-brand 9v's might be as much as $8 in a convenience store. That's a
lot to pay for a backup battery in an alarm clock (the usual destination
for my used cells), or a toddlers toy. Servicable cells are a perk of
the job. I never buy them, either way (unless jobs with 9v's haven't
come my way lately). Professionally, the client pays. Personally, I
get free batteries.

Either way the cost (to me) is trivial.

But if you're using decent quality batteries and equipment, the life
should be pretty consistent. With mine, it's 9 hours so I change at 8. If

The breaks don't always come at 8 hours. So, as you say, at lunch I'd

change them, depending on the projected balance of the presentation.
I'd also watch the reciever battery indicators like a hawk if they
started to get low. I've been known to sneak up and change them on the fly.

But as I said earlier, 'pro' batteries bought by the box already come with
a clip on protector. Or do in the UK. And are cheaper per unit than buying

I've never bught (my clients haven't, actually) anything but Procells.

I don't--and I don't allow anyone to--put the protectors back on the
cells, or put them back in a used box. In the box--or protector
on--means 'new battery' to me. Too much trouble to keep track during
the heat of battle. If the stagehands or anyone else want the used
cells, they need to get them out of my sight.

I don't have time to check (or recharge) used batteries. I do check the
mic's indicator whenever I change out the cells, though. I've never
gotten a bad Procell; but there's a first time for everything.

No-one's time should be that important unless they're saving a life or
something. Time these devices were fitted with lithium ion batteries.
Changing out sets of those occurs less because the energy density is good,
there;s no 'memory effect' or other reason not to top up on demand, the cost
can be low enough to compete with Procells, and changing them is as fast, or
faster, given no fiddly pop-cap connector to mess with. And you top up your
batteries at night in a charger and in the morning you have lots of new
batteries. Their energy density is good enough that you'll likely get through
a day or more of the demands a microphone makes, so if time really IS si
desperately im,piortant that you think you can't find enough to charge a
battery, think again. It will save you more than it costs.

The only serious obstacle is the possible lack of 9V PP3 shaped lithium ion
types. I don't think I've seen any yet. But a decent mic could use a DC-DC
converter and run off one or two standard CR123's just fine, and for a lot
longer too. The use of space for chemical reaction is far better in large
cells than groups of small ones.

As i just said in another post, most mics these days use AA's. Last
tour I had 11 presentation systems, each with four RF receivers; and
each receiver had a lav pack and a handheld mic...presenter's choice.
That's a lot of batteries (two per). Additionally, we had a general
session (the 'main tent') with a dozen RF mics. I never got a bad
battery, but I didn't have time to monitor each mic for 15 minutes,
either. Usually either I (or my designated crew) checked batteries on
each major break and replaced if below full scale on the mic battery
indicator.

All that said, I did have to shepherd eight walkie-talkies that all used
rechargeables. That was trouble enough....

The new type (eg. Uniross Hybrio) of NiMH have a very low self discharge. The only problem is certain devices like smoke alarms not liking the slightly lower voltage.

See my multiple posts on the subject. For most presentation purposes,
the proven reliability of the good old alkaline--fresh out of the
box--is superior. One less thing to worry about in a complex and

The cost of having a show 'go down' is much more than that of fresh

My answer would be is you can virtually guarantee the performance of a
decent make alkaline. And I sometimes use a great deal - my personal
record for number of radio mics is 38 at once. It really is rare to get a
faulty battery.

Trouble with rechargeables is they don't maintain the same performance
throughout their life - which makes knowing when they must be changed
rather hit or miss. Plus the fact that most give little warning of running
out - unlike an alkaline - due to the different voltage discharge curves.
So what might be a benefit on a high power demand device like a drill etc
is a liability on a low current one.

Of course if you know they will only be used for a short time - like say a
church service - rechargeables can and do make sense. But this isn't
usually the case for film, TV and conference etc use.

All of which makes perfect sense - in the context of a NiMH or NiCd. As most
of this talk has gone to discussing microphones, consider a moderate steady
load. You want that to be supplied with equal constancy, if possible. If
nothing else you know what you'll get during the discharge if it IS constant
in voltage and has adequate current. Lithium ion cells do this fine. They
fall off at the end but not so fast as Ni-based cells. Actually the fade time
at end of discharge when powering a microphone should be fairly long, you'd
get early warning if you knew what to look for. You might still get a couple
of hours of use from start to end of fall anyway, if current demand is less
than 50 mA (examples below), given two CR123A cells. Total use is more than a
half a day easily, even with the lower 800 mAH capacity. With light loads the
safety is very good. Newer batteries even have the clout to power a drill, if
they have lithium titanate anodes. Their shelf life is actually BEST at
around 40% charge so they don't mind being left waiting around, and they can
be charged at any time. They store very well when cold so they won't mind
travel in an unheated truck. They work fine at sub-freezing temperatures too,
so long as you don't go too low, and not many things demand that of them in
use.

Time to running flat is long enough to give you the nice early warning you
can expect from alkalines, but is flatter for longer, before that happens.
And when you've charged them many times, the loss of capacity even after
hundreds of charges and a couple of years of use, will still give you better
performance after a charge, than an alkaline fresh out of the box. If you
charge them each night they'll probably never run flat, and as they'll spend
most of their lives at around 40% charge, give or take 40%, they should last
a long time.

If reliability is critical, run their first couple of charges in a non-
critical situation. Label them with coloured electricians' insulating tape to
code them, or whatever it takes to identify and organise. If I had to put
batteries in 100 microphones I'd rather use lithium ions than alkalines given
what I've seen of them so far on similar steady loads in critical situations
(hours in cold and darkness with a flashlight making the difference between
safety and injury).

What he said. The risk just isn't worth it for the price of a few
batteries.
There`s also the factor that some low end radio mikes seem to object to
rechargable batteries (certainly nicads) It`s possibly the batteries
internal resistance changing as it discharges.
I`ve not really studied it, but when the rechargable discharges beyond
a certain point, the transmitters agc seems to get screwed up and
unstable, feedback is the result. Maybe someone with more technical
understanding can explain.

Then use the new type of NiMH, the pre-charged ones which don't lose power sat on the shelf. Take them out the packet and they are as good as alkalines. Only keep them for a fraction of their life if you want a nice long charge, and put them in a trickle charger when not in use.

There are three problems with them. The first is that they are supplied
charged, but only about 80% charged. While they take longer to discharge
on their own, if they sit on the shelf for a year or so, they very well
may be flat.

The second is that they do not reach their full capacity when recharged
until they have been through 3 or 4 recharge cycles. I have found with
the ones I bought it took even longer, sometimes 10 cycles to get
any useful life out of them.

The third is that they have a higher internal resistance which limits their
output current. That is why the rechargeable alkelines that came out around
1995 never really took off. They were lower in capacity to the disposable
ones (about 80%) to allow room for expansion, and they did not put out
the current that nicads or regular alkelines did.

They also do not charge as fast. I charge mine in a 7 hour NiMH charger,
but have to do it twice. Using the little fixed rate charger that came
with a set, I have to charge then for at least 24 hours.

Geoff,

Do you have any info that indicates that they can't put out as much current
and/or have higher internal resistance (over time) compared with alkalines?

I have been using the Hybrio hybrid batteries in a Canon SX100IS digital
camera for about a year now and I haven't noticed anything problematic about
them. They last a LONG time without any special conditioning. I use a Maha
MH-C401FS charger (set to 'slow').

I've used alkalines in several different cameras and have had horrible
results with them.

Then use the new type of NiMH, the pre-charged ones which don't lose power sat on the shelf. Take them out the packet and they are as good as alkalines. Only keep them for a fraction of their life if you want a nice long charge, and put them in a trickle charger when not in use.

In a word; no.

We don't have trickle chargers in the truck that takes them to the next
city; nor the time to monitor their health. A new Procell is a 'known'
resource. It always works, IME. It always lasts about the same amount
of time. When it's exhausted (actually long before) we discard it--or
switch it to less demanding tasks--and grab a new one (which will last
exactly as long as the last one did). I have a box of used ones right
across the room. Want some? They're great for kids toys, flashlights,
portable radios etc.

You're not listening. Use them yourself if you want to. I value my job
and my reputation much higher than the price of a new battery...or a
thousand of them.
