Olight S2R Baton II charging issue.

Does anyone know whats happening here and what I should do about it?

When I connect the magnetic charger to the flashlight, instead of turning solid red to indicate charging, It instead turns red while repeatedly flashing green as well.

Is this the end for my baton?

I don’t think it has to do with the battery. Maybe it has to do with the cable, eventually the power source, or even the bottom of the flashlight.

Is it damaged (the bottom of the flashlight)? Also, do you have any other similar cable to test in the flashlight? Maybe it is related to that.

Ive taken very good care of the cable kowing its my only way to charge this light.

There doesnt seem to be anything visually wrong with it.

I guess this is just the end for this light…

Maybe take apart the flashlight, give parts a quick wipe, put everything back, tighten everything. But wait….then untighten everything again and tighten it back up again.

Not damaged in any meaningful way, just some cosmetic “damage”.

Next time I am at my dads, I can try his charger with my light and vice versa.

Thanks, I’ll try that.

Edit: Diddnt work.

Still behaves exactly the same after doing that.

Video here just shows that the cable is in good condition. Lights up Green as normal when plugged into power source, and still flickers when connected to the light which is not normal.

I dont trust leaving it to charge like this not knowing whats happening.

Dont need to start a fire or anything..

So I visited my dad today who also owns this light.

Tried his light with my charger and there were no issues.

Tried my light with his charger and experienced the same flickering.

So whatver the problem is, its with the light and not the charger.

Have you cleaned the contacts on the flashlight tailcap with alcohol, maybe a pencil eraser?  Looks clean in the videos but sometimes that solves contact issues.  If the charger interface is good then perhaps the battery and springs in the light need the same treatment, especially the little brass ring in the bottom that contacts the battery positive.  Sounds like you've already used a different source of power (at your dad's?) to rule that out.  Does the light exhibit any weirdness in use?  If not then chances are it's the contacts/interface between the charger cap and the outside of the tail cap.  Be sure that plunger moves freely because it has to poke down against the center contact in the tail cap and provide good pressure (and be clean). 

The charger for the little S1R II is the only one I have but it looks identical.  It doesn't flicker unless I really wiggle it around to the point of breaking contact and seems to be drawing a steady 850mA from the wall wart.  I also have the similar Olight usb charger has which uses two caps for either end of the battery.  It has exhibited some red-green flash and also the flicker here a few times but that has been solved each time by a simple cleaning of those contacts.  Same thing on a Rofis which uses more or less the same setup.

I emailed Olight about it and thats what they suggested as well. Still flickers after cleaning though.

Since It uses the proprietary magnetic charger, The light is never opened and the battery is never taken out. Should it develop these types of issues if its never opened?

It has the same flickering using my dads charger.

My dads light is just fine using my charger.

It works normal otherwise, but the battery is really low now so ive stopped using it.

Again, its never opened and the battery is never removed. So nothing should really be able to get dirty inside?

I can still try cleaning it all though.

I dont feel comfortable just letting it charge and hoping for the best.

Im worried about damaging the battery, or worse, fire/explosion?

Thank you very much for your input.

Ill try cleaning everything as you described and seeing if that fixes it.

I used to complain about olight using the cheapest junk batteries they could find, and making them proprietary. But nobody would believe me. You used to be able to use quality non-proprietary batteries, but the charge function wouldn’t work. Don’t know if you can still do that or not.

Maybe try switching your dad’s battery into your light.

Did you ever pick up a multimeter so you can check voltage?  I'll have to try this and observe but I wonder what these chargers do when cell voltage is pretty low.  There's always a period of initializing and pulsing with any smart charger before it settles into a charging rate...I don't suppose that would show in the indicator led but maybe? 

If you never open/remove then yeah, it should stay clean inside.  Personally I usually take mine out and charge it in a normal charger because I'm not terribly fond of the charging rate the mag charger provides the little 16340 cells I have (over 1C charge rate, I think...measured at the wall and on the mag cap, but I can't tell what it's actually doing in the circuit when the battery is involved.  I think it's a bit too high, though, for my liking.).  But it doesn't hurt to clean it anyway.  The plunger is the spring loaded nib on the mag cap itself.  One of those threads linked above talks about a malfunction there where some cleaning (and lubing, which I don't think is necessary) fixed his situation with a plunger that stopped traveling freely I guess. 

When you clean, give it some good pressure.  Sometimes you can't see oxidation like you can some grease or schmoo.  Q-tip with alcohol is fine (or a clean cloth even).  With the other usb charger of theirs, I was somewhat surprised when a legit cleaning fixed it because they really didn't look dirty and I'd already wiped them.  This may not be your solution but it's the first place to start, and it seems as though you've ruled out a couple other possibilities including (I assume) power source. 

I'm a little curious how the bits in the tail of the light are set up.  When I measure voltage on the mag cap the plunger is negative, ring is positive.  But in the light, that center post that the plunger contacts looks like it's straight through to the positive contact on the battery.  Hard to see in there and there could be some swapping by via on that little board.  It'd be interesting to see how they're assembled.

As far as I know you still can.  I'm not particularly fond of any of the onboard mag charging setups but I think the way Rofis did theirs was a better idea...no question about cells or orientation, just need the prissy charging cable.  I don't see any advantage in reinventing the wheel with tailcap mag charging other than being able to more easily stand the light upright on its face when connected.  Interesting exercise for the engineers/designers I suppose...gives some extra bullet points for the marketers to use...hopefully ensnares at least as many customers who will be locked into buying your proprietary junk as it does drive away others who don't want to be locked into it.  Someone probably enjoys patent awards and accolades, too.

I did happen to unwrap an S2R II 18650 out of curiosity.

I regret it but maybe sharing this is useful to some people here.

I only did it because olight sent me a whole new S2R II for warranty and let me keep the original faulty one.

Still regret it though. Oh well.

Looks like its an LG?

LGGBMH11865 / S006A067N1

Next time I visit my dad I can try swapping batteries.

If I hadnt unwrapped this one I could have tried it.

I suppose it can always be re-wrapped.

Unfortunately not yet.
Without getting too specific, I just cant afford it right now.
My dad says he thinks he has one in his storage unit, so Im waiting for him to have time to go see if he can find it for me.

I personally need lights to come with their own battery and charger, or im just in over my head.

Im a dumb dumb lol. I just want to buy lights as I would any other consumer elctronic and just use it care free.

Since im not a proper flashaholic and dont already own my own cells and chargers, I like that there are companies like Olight for the average dude like me.

Id prefer if Olight just used a version of standard USB instead though.

For now, the lights I own, I actually need. But there are a bunch I would like just for fun.

You un-wrapped a brand new battery? LG cells are good cells, but these MH1’s along with the F1’s are LG’s cheap line of cells. I think the MH1’s are rated at 10A, and the F1’s 6A, something like that.

That disk on top of the cell is the charge and protection circuit, and looks like it adds considerable length. Therefore, a standard 18650 samsung or sony, probably wouldn’t work like they used to on the older Olight flashlights.

Most likely that battery circuit is your problem.

This is a LG F1 flat top. No protection or charge circuit

I unwrapped the original faulty lights cell when I received the new one.

It was just sitting collecting dust as it still does now.

Ah, got it. Try taking the battery out of the new light and testing your old light with it to see if the battery was the problem. There may be nothing wrong with the flashlight itself

When that light was having its issues, I swapped batts with my dads and determined that the problem was indeed the light and not the batt.

These are the newer olight proprietary cells with that huge circuit. It’s probably more like an 18700+ size and may not fit in a standard charger. Also, the positive and negative are on one end of the cell.

I’d bet the main reason Olight does this is, to sell $2 dollar batteries for $15.

Im starting to think I may need to just find out what the best 18650 is, get one or two, and then only buy lights that can use it.

It has been brought to my attention in another thread that my Manker’s 18350 is also crap and not even powerful enough for the light it came in…

@RobertB

Now you’re getting confused and that may be my fault.

I originally had a S2R II that started glitching out and behaving erratically, and I swapped its battery with my dads to see if it was the light or the battery.

I determined it was the light and Olight sent me a replacement.

I did nothing to this new light but use it normally.

I then unwrapped that battery from the original erratic light.

Now my replacement light is having the issue of the flickering cable light when trying to charge it.

Gotchya. So, did you swap the battery with a known good one on your new light or not?

I have to wait until the next time I visit my dad again to try his battery in my light and vice versa.

I was just using the @ to make clear my comment was directed at you being that I wasnt using the quote feature there.

I just felt that it was getting a little cluttered being quotes inside of quotes inside of quotes at that point lol.

So I wasn’t confused after all. That was exactly the point I was getting at in the first place. You never ruled out the battery as the problem.

Okay then I got confused lmao. That is true, I havent ruled out the battery in this case.

I dont know how the @ works on other platforms. I dont use any.

I just went searching for the specific quote and I guess I internalized it wrong.

What the person actually said was

Quote:
The battery that comes with it does not do the capacity that they quote but it is acceptable for the format.

Still, Im getting very overwhelmed again and discouraged to say the least…

Im too “dumb” to do what you guys are doing. I dont have an electrical degree or…

I just need a light for regular people. (not aa or aaa lights though)

I thought that was Olight. And then Manker.

Turns out thats is just not the case.

Maybe I just have to wait a few more years and hopefully they will become more accessable to the average joe?

I cant do this anymore.

I want to go back to that first 6 month period when I got my very first S2R, where I was over the moon about my awesome pocket sun. Completely Ignorant of the flashaholic world. Assuming it was gonna last forever.

Not that Im a proponent of iphones, but at least it does the damn job I bought it for without having to know anything about how it does it.

Wheres the iphone of flashlights? Again, I thought that was Olight.

*sigh *

Convoy S2+ with a simple off/on switch and 4 modes. IMO, a better flashlight than the Olight and 1/3rd the price. And you get to deal with the owner who’s a member of this forum.

Thats a light that requires me to have an electrical engineering degree though. If it doesnt come with its own battery Its too advanced for me..

I think I should leave.

I clearly dont belong here.

Im probably getting on peoples nerves.

I should stop invading your (the blf at large) space.

Im all take and no give, and likely misusing this forum to get answers to questions im too inadequate to figure out for myself.

And then degenerating into petty rants about my situation.

I wont try and delete everything like I did last time.

Thanks to everyone who tried to help.

Sorry to everyone who was perturbed by my presence.

Later.
