Zebralight SC60

But ... if it does have a ring surrounding the positive terminal ....

What else would be the purpose of that ring ?

The design purpose is to keep the FLAT negative end of a battery from contacting the pos. terminal .

It's almost as flat as a + end of a flat-top design cell. The ring only has to keep it separated a Few hundredths of an inch - to be effective .

If it has a surrounding ring ....... I'm leery .

Those who now have SC60's ......

Does it have any type of RAISED reverse polarity protection ring on the circuit board/battery side ?

It would help to know about that at least .

~

Mine does not as I look inside all I see is the board and a raised post.

jhc37013 ,

Can you please verify if it has an outer ring , to hinder contact , in some circumstances ?

Or is there ONLY a protruding pos. terminal on the circuit board ?

I'm sorry you guys are having trouble with your 2600's mine works just fine with them. I can see a clearly raised post inside the head for battery contact.

I believe you jhc... it's just a mystery now... maybe since you got yours a while back and we are getting this new batch there is something different with our SC60s?

We need more data!

There is only the protruding post and nothing else.

Ha ... thank you ... you answered my question as I was typing it .

Didn't notice your reply.

OK ... now to those whose light won't work ....

Please look inside and see if you have a surrounding ring ... in YOUR model .

If no ring ... I would suspect a bad light .

[OrezzerO]

I'm not understanding the ring question...

Here is mine:

Well .... that pic left no doubt ...... TREMENDOUS picture !


Sorry , but you must have a bad light if it won't light up.

Did you test your battery ?

~

 

[OrezzerO]

Thats the best the iphone could muster...
I really dont have anything to test it with... my first 18650 light...

I purchased one of those USB bat chargers from cottonpickers and have used it to sucessfully charge some AW123s and one of the two AW 2600 18650s I *just* bought from lighthound. I did not charge the other 18650 from lighthound b/c the one i hooked up was pretty much topped off and showed 4.13v on the charger.

so you really think we both just have bad lights?

I wonder if zebra does a quick test on lights before sending them out?

OrezerrO ,

Also , is the end of your battery tube clean to make GOOD contact .

( sand it lightly - NO lube )

Otherwise , your light must be bad .

Do you have a CR123 size Dummy cell (all aluminum) you could pair with a Rcr123 cell , just to see if it works .

I'd also try it with the OTHER 18650 cell you got. New cell charge is enough for test.

That's all I got .

This is the best pic I could do.

Thanks ... that's DEEP ......

but OrezzerO got you beat with his ZOOOOM .

~
But now I know they have NO ring :thumbsup:

[OrezzerO]

now *THAT* is a good macro shot...

What is interesting is that although the circuit boards look similar they are obviously a different batch... my board has a fraction of a mm between the board and the body... yours seems to have quiet a bit of space.... lots of little differences...

could be something to it or a red herring

 

[OrezzerO]

and your contact looks nice and sanded... maybe there is some shelac or something on mine.... i cleaned the spring contact a little but i really dont want to do much more... if I was zebra i wouldn't want to take returns where the light had been tampered with...

 

[TooManyGizmos]

~

Yeah ....... but clean the end of the tube.

~
( ...returns where the light had been tampered with... ) learn to tamper gently

 

[jhc37013]

I have been using a 2200 button top lately so maybe that could explain why my terminal looks different, however maybe it's just the camera angle's but your post does seem to be a bit wider and flatter than mine.

:nana: ..... I hope you guys are not reversing your flat-top cells

Double check the polarity markings on the cell.

~ ................... just to be on the safe side .

 

[jhc37013]

And here is the reason why the tailcap rubs the contacts on the AW 2600 negative side, unless you grind the nubs off the battery as suggested by TMG. The very large contact spring on the SC60.

SC60 left / H60 right

And finally a few of the family, not a very good one but I know nothing about camera's.
