Glovebox torch (flashlight) rebuild with LED

Post by GRNSHRK » Sat Dec 18, 2021 12:16 am

Well, I got tired of F'ing with the friggin' stereo and decided to rebuild the glovebox flashlight with new batteries and an LED \:D/

This involved quite a bit of creative rewiring even though this particular LED doesn't appear to be opposite polarity that many are :-"

And a special shoutout to Tommy for hooking me up with the sources and part numbers for both the batteries and LED =D>

Even though the batteries came from Europe and were stuck on a container ship for who knows how long ](*,)

But I gotta tell you guys, this thing is blindingly bright :shock:

Hopefully it will charge when I plug it in [-o<

Thanks Bob, glad I was able to help. Good job and it’s amazing how bright the little LED is and I’m glad to hear the polarity is not the opposite like mine.

That looks great!
I already have that same Varta battery as I wanted to repair my flashlight.
Now I see that LED, I want to do that as well.
Can you share the part number of that LED Bobbo?

I've replaced the batteries before but I think I must have ended up with non-rechargeable batteries - could you provide a link to the batteries and LED's please?

I have bought the Varta 2/V250H rechargeable batteries.

Paul noted the correct battery stack, although you do need to take the stack apart as only 2 of the batteries will fit, due to the height :-"

I purchased them from Newark Electronics, can't find the link that Tommy sent me, but he probably still has it [-(

I removed the center battery so that I could use the convenient solder tabs, which are a great help. I'm not sure how the original had the wires soldered directly to the battery surface, as I had trouble removing them because the battery acts as a heat sink and I couldn't get it hot enough :-?

The LED came from Superbright LED's, again I don't have the link but I do have the part number, P/N E10-WHP :-k

I'm still trying to bond the 2 halves together, I tried Silicone RTV but it didn't hold good enough, probably because there isn't much surface area to bond to #-o

The goal is to be able to disassemble it in the future, should the need arise [-o<

I'll ask Tommy to post the links for us =D>

Thanks for the info!

I would use a few small drips of superglue.

I have several white glovebox flashlights if any BC folks are in need. A donation to BC will get one in the mail. Seems like a good upgrade at a decent cost as opposed to the $100 units on eBay.

I did an extensive search online and in the US I was only able to find the Varta batteries stacked with 3. I wish I could have found 2 stacked, it would have made the job much easier. Be careful with the resistor when you solder the wires. I was able to find new resistors from a local electronics store.

Anyways, I ordered the batteries and LED from:
Batteries from Newark Electronics. Part number: 55625603059
LED bulb from Superbrightleds. Part number: E10-WHP

Once you receive the LED, check the polarity. You may need to switch it in order to have it charge properly when plugged into the glovebox.

Glue: I’m currently using Testor’s plastic model glue. I used a toothpick to apply it to the edges and so far so good. Don’t want any glue(s) stronger in case the batteries need replacing in the future.

I found the 2 stack at AMAzon in Germany, except it is $33 for it shipped and I am not sure it will make it by the time I leave Portugal, and they don’t ship to the US. I may try locally.

What did you do to convert it to a 2 stack? Was all that was basically needed was to remove the plastic wrap or are the otherwise held together?

Thanks

Jim, the 3-stack from Newark is only $13 and change, plus shipping and applicable sales tax, of course :roll:

The green sleeve can be slid off intact, by simply bending the solder tabs out of the way :-"

The 3 batteries are held together with thin metal of some sort that both wraps around them and provides contact between them, via what appeared to be very small spot welds :-?

They can be popped apart using a metal paint scraper, also a suggestion from Tommy that worked well =D>

Once apart and the sheet metal removed, the evidence of the spot welds will still be visible, providing plenty of electrical contact between the 2 once stacked together \:D/

The original had a thin piece of metal "tape" for lack of a better term, in between the batteries, which I reused, just to ensure even better contact between the 2 batteries :wink:

I would recommend using the top and bottom batteries so that you have solder terminals for both the positive and negative solder connections that you will have to make :P

Verta batteries are from Germany and it seems like an easy find. In the US, not so much. You can order the 2 stack from Amazon but with the delay in shipping, there’s no saying when you will receive them. (I’m waiting for front brake rotors, so far 3 mo’s from ECS). As Bob mentioned Newark is much cheaper. That’s the only place in the US that sells them as far as I know of.
