    Yes, they are good for just about all Li ion rechargeables. They have multiple settings from low ( small batteries), to high ( large capacity).

    Need some battery help...from the knowledgeable!

    I have an AW 16340 RCR 123 protected in my Haiku and went on a 4 day trip to Philadelphia. I charged the battery 4 days before, as it usually lasts a very long time, and I did not use the light on the trip much.

    Aboard the aircraft on the way home I needed to check the floor, and it just went off - dead off. Is there a problem with this battery? Normally, I get up to three weeks at most with normal use of on a charge of it sometimes.

    In the end it was not a problem as I pulled out one of the four other lights I had on me, including my XML Haiku. I just did not want to haul another charger on the trip as is was so short.

    Any thoughts to limited use with recent charge? And why it just snapped itself off or is this normal?

    What I was doing was checking on our Philadelphia cat under the seat, we moved the feline to our desert home with the rest of our cat family.

    Thanks for any info.,

    Best,

    So it provides absolutely zero output, sitting now at 3.7V ?

    Does that Haiku work properly with a different (fresh) battery ?

    The rechargeable went off, and I put a primary CR 123 and it came back to life.

    So the rechargeable in question is still at 3.7V, has not been further recharged or discharged, but will not power your Haiku ?

    Well, I charged full after about two weeks, and into one week with little use it just came on for a second then was dead after that. Just went off. It seemed to charge normal today, just like normal.

    It's that it has never caused the light to fail like that before. Up to now it has worked just fine.

    when I put it on the charger, it was dead, however it has never just stopped working like that before, normally you notice switching issues of the 3s modes and it is time to recharge, not a complete blackout of the Haiku.

    After charging the battery it powers the haiku as normal.

    It sounds likely that the protection circuit tripped, possibly inappropriately.

    I would suggest, at the least, clearly marking that specific battery as questionable (perhaps defective or damaged)

    And, if you would rather not have to worry about it, simply replace it.

    I think you are correct, I will replace it.

    Thanks so much for taking the time to help me with this battery problem.

    Much appreciated.

    One more question on these protected batteries, should you wait until they go dead or so low it is hard to shift modes, or charge them once a week or something of that nature?

    This battery caused the most reliable light made in the world to unusable.

    Again thanks,

    Default Haiku Batteries. Which Do You Use? Primaries or Rechargables?

    What was the voltage on the cell before you charged it again (after the incident)? Any possibility the switch on the light may have been activated and drained the cell?

    When I went to charge it was dead, I don't think it came on in my pocket, I would have felt that. I was flying do the X-rays hurt them?

    I look at it and no longer trust it.

    Thanks so much,

    RedLED,

    Similar issue happened to me in the past on 2 occasion. Both when I went on away trips and both having different 16340 AW Protected black cells. The cells I bought was in 2008 and this occurance happened sometime late last year. Thinking that the cells are ageing, I bought another batch to power up my lights as I too bought in a batch the same time in 2008. So having 2 issues would also mean that the rest of the batch would eventually fail. Anyway new fresh cells came in and when I tried to charge it, I noticed that I was having contact issues with the charging post of the charger. I was using the WF-138 charger. And only then did I realised that, the issue was with the charger and not the cells. Bought another charger the Xstar VC4 which displays charge current and mah, and all my old cells are working to this date albeit reduced capacities. For me I charge these batteries as and when they trip the protection.

    My battery was from July 2016, and I would say it is still kind of new. My charger is an xtar VC2.

    Is this battery any good to use, should I give it a second chance or toss it and replace it? Any advice is welcome. I have switched back to a primary for now.

    I have many Mc Giz lights, however, my EDC Haiku XPG R5 is the one I was using the protected rechargeable in.

    Thanks,

    RL

    In all honesty, the light was either accidentally activated or never fully charged to begin with. It isn't really likely the protection circuit broke unless you use it in a recoil environment.

    Try the cell for a while where you aren't worried about being left in the dark and if it works its fine. If the protection circuit fails prematurely then either take the circuit off and use the bare cell in a light with a built in protection circuit or toss it.

    I would also suggest getting a multimeter and measuring the voltage of the cell at points in time. When the protection circuit trips and you bring it back to life but before charging it reads 3ish volts you know it's working fine. But if it trips and then you read 4 volts still then you know the circuit is defective. 3.7v is the nominal voltage of the cell and doesn't really say much as all li-ion are that for al intents and purposes.


    Theres no real danger past it shutting off prematurely worst comes to worst.

    Thanks, I do have a DMM and will check it. I gave it a charge after it tripped and it has Been just sitting here unused except to put it back in the light to see if it worked, and then removed it.

    I will give it another try. Should I measure it and use it or top it off on the charger first? Also, my DMM can put a load on it for testing should I use that setting or just measure the straight voltage?

    Thanks so much for the advice.

    I would top it off in the charger, let it rest at least 10 minutes and check the voltage with no load. Then measure it the next day. The voltage should not drop by more than one or two .1 volts. If you see it measured at 4.15V off then the next day drops to 3.9V either repeat the test wondering if there was an error in the measurements perhaps the contacts on the DMM weren't seated correct or you can assume the cell is defective and recycle it.

    This is a quick way to measure the self discharge of a cell, which is a good first step to determining the health.
