I want to keep some NiMH rechargeable 9v batteries in my tool bag (well, my
meter bag, actually). I am currently running a double loop of electrical tape
around the entire battery to insulate the terminals.

I'd like to use something more durable (one battery has had a terminal peek
through the tape) and was thinking about something like a battery terminal
connector but made of insulating material like nylon (probably of some
cheaper plastic).

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

Ideas?

I've seen all-plastic plugs for 9V batteries that were designed for just
this purpose. But they came on batteries supplied with a product. I've never
seen them for commercial sale.

How about punching two holes in a block of foam, then taping it on?

Pro Duracells PP3 size in the UK come with a plastic clip on cover for the
positive terminal as they are usually supplied in bulk - ie no individual
wrapping. So that's to prevent shorts in a partially emptied box.
Find a film or TV crew and ask the sound guy for some.

Start harvesting the snap-on battery cords from dead electronics. Cut
the wires off short (preferably inside the vinyl housing a bit). Snap
them on -- there you are!

Most of those break after a few operations.

You could take a dead battery apart and use the connector block from that
after insulating. Usually far stronger than the wire ended connectors.

That would be my suggestion, you could insulate the terminal rivets with
blobs of epoxy glue or with some makes of battery the blank plastic insert
from the bottom could be superglued on for insulation.

You can buy such cords, but the cheapest/fastest solution is to take
apart a dead battery and tape up the back side, with a bit of plastic
behind to prevent rubbing through -- the battery may have this anyway.

In my impoverished schooldays, no battery was ever thrown away without
salvaging the connectors.

Small 4 mil ziplock bags. Put the batteries in them with the
terminals towards the zipper. Put the dead ones back in, in the other
direction so you can tell them apart.

I'd like to use something more durable

I just use some stiff paper, wrap one end of the battery
like an Xmas present, and tape the paper. This makes
a paper friction-fit cap, which has never failed me.

Strapping tape is permanent enough, but some kinds of
book-repair (urethane?) tape are better. Kapton is overkill,
but... the problem gets dead, it stays dead... that works.

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.

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.

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
I were using them for an all day presentation where they could only be
changed at say the lunch break, good rechargeables *might* be worth it.
Assuming your mics have an SMPS that can work on the lower voltage.

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
retail - unless you're willing to use no name stuff. At the moment I'm
using Energiser.

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
CPC in Preston. My last batch of PP3`s worked out around 80p each.

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
I were using them for an all day presentation where they could only be

Assuming your mics have an SMPS that can work on the lower voltage.

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
retail - unless you're willing to use no name stuff. At the moment I'm

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.

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.

I used to use plastic DIP chip shipping tubes:

http://farm4.static.flickr.com/3200/...4213d96b_o.jpg

Cut a channel along the top to hold the batteries by their negative
terminals. For better grip, first drill holes the diameter of the
positive terminals. Plastic tubing, slit lengthwise, also works, and
the flexible type can be wrapped all around the battery for a better
grip.

Or you could glue the batteries together with double-stick tape or
silicone RTV, just enough to hold them securely but not so much that
they're hard to twist or pry apart.
