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?

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.

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.
