Autodark helmet failure - repair attempt, need battery & holder advice


First posting in joining.welding, I hang out over rec.metal.
My cheapy autodark helmet quit recently, about 3 years old. I Googled
autodark helmet repair and did not find much, except for this thread:

the cross posting. Summary of which is: all autodark helmets
w/ solar cells also have batteries, not they have capacitors,
batteries,=85blah, blah, blah=85.Store your helmet in the sun to extend
the battery life. The advice was a bit late but I placed the autodark
module in a southern facing window for 9 weeks. On the first strike
the autodark was noticeable slow, but was OK for the following
restrikes. After a 5+ minute pause, the first strike was once again
slow.
With not too much to loose, I used an Exacto knife and cut open the
case seam:

CR2330 batteries soldered to the board. I found a replacement
battery w/ the solder leads attached

but then I thought why not mount the batteries on the outside of the
case as in this simulation

is plenty of room between the module and my forehead for the
batteries.
So should I stay w/ the 0.255mAh CR2330 battery or go with something
else since I am no longer constrained by the package space? If so
what? I found this puppy w/ a much higher capacity

but it also has a higher self discharge rate.
SO where does one go to buy a very small qty of electrical components
today? In my youth I stopped by Radio Shack or Olsens Electronics for
parts. I found a nice looking battery holder online (in min qtys of
12). I need a battery holder that I can bond or screw/rivet to the PP
(guess) case of the autodark module. Who are some good vendors that
are willing to deal in small qty orders and don=92t have outrageous
shipping rates?

mouser.com They will sell you 5MM or 1 of just _about_ anything they carry (not tape-mounted parts, usually, but any bulk stuff for sure).

Digi-Key tends to be easier to deal with and have great customer service.

I use both, but prefer Mouser. Shipping is usually faster and cheaper than Digi-Key, especially if your order fits in a USPS flat rate box.

You could also try yard sales. Kids toys and cell phones are common discards.

Same as the others, plus

and http://www.halte= d.com for surplus. Also,

sometimes has electric/ electronic goodies for cheap, worth going to it for the entertainment. Herbach and Rademan lean more towards electromechanical stuff. With any of the surplus stuff, buy if you see what you want, it may not be there much longer.
Radio Shack has a bunch of stuff on their web site, sometimes they even have it in their stores. Most components and loose parts have been moved to a couple of sets of drawers in a dusty corner, you'll have to ask. Helps to look it up on the site first, then take the part number in, all of the places are arranged according to part numbers.
If your batteries are connected in series, you might look for a holder for a CR123, it's 6 volts out of the package, might last longer. Both Mouser and Digi-key have battery holders for both coin and tubular lithium batteries.

(clip) ^^^^^^^^^^^^^^^^^^^^^^ I think most of the training that Radio Shack provides their clerks is on selling cell phones. If you try to explain something technical, or describe a needed part, you probably won't get very far. Good advice to go in with the part numbers.

One battery holder, not necessarily the one you want:

But, this is about batteries; those can't be shipped USPS.
Some of the solder-in cells are lithium primary cells, and others are lithium rechargeable cells (VL2330 is rechargeable and BR2330 is not). Make sure you aren't using an incompatible cell to do the replacement.

Sure they can. USPS even gives advice on how to ship battery operated devices...

I always wonder why companies provide a link on an image to open up another window showing the same size image.

CR123 is 3 volts.

Since a welding hemlet protects your eyes from serious risk. Is it worth saving a few bucks by doing home repair? And what happens if the protection fails? Mass doses of UV? I'm not sure. But I'm concerned for your eye sight.

Provides UV and IR protection when off. It is the visible light that it shades against.

The glass in the hood provides the UV protection, with or without the electronics, the electronics just cuts the dazzle down to an accepable level. Hoods are expensive enough that refurb/repair is viable. If the filter were cracked, that would be an item for concern. But it's not.

Yup, you're right. Thinking of this pup:

had a green laser that used it.
