Is there any way to revive a tenergy AAA NiMH cell? It was in a small Mag lite and has had very limited use. The light was working one day and a few days later it would not light. 2 of the three cells in this light began recharging but 1 does not even register in the tenergy recharger, or is it just a bad cell? Thanks. Is there any way to revive a tenergy AAA NiMH cell? It was in a small Mag lite and has had very limited use.

The problem with the high energy, all the NiMh cells is that the voltage is significantly lower than 'normal' / carbon cell batteries. Approx 1.2V Versus 1.5V. With a filament bulb it matters a little but an LED has a specific min voltage to fire. So the cell can be loaded with juice (so to speak) but be too low to fire the diode. it affects some electronics in the same way. My digital pocket recorder has the problem although the Tenergy cells seem to keep up their voltage, ie work longer with my recorder (than other of the Hi Output NiMh cells).

All I can tell you about that is the other day I was using the flashlight which eventually became dim. I replaced it on the lamp. Although connected to the AC adapter, the red light did not come on and the lamp would not operate from the switch on the base. I thought I had a problem with either the base or the AC adapter. The next time I entered the office where I keep it, however, the lamp was brightly shining and the red light was on. I concluded that the flashlight part must be charged at least somewhat before the lamp can operate from the AC adapter current. I hope this helps.

Your question relates to AAA cells. I ordered and reviewed AA cells in this same Amazon Basics brand. These are rechargeable Nickel-Metal Hydride (NiMH) cells. I found the AA's to be quite good. If your solar lights use rechargeable AAA's I think you will find these to be the same quality as the AA's and to be a "happy" choice. Some have complained that the AA's do not have quite the claimed storage capacity (miliAmpere-Hours or MAH) but I have not given them a formal MAH test. However, they have already held up better than any other rechargeable AA's I have used. I suspect you will be pleases.

My pack of AA purchased in January 2015 says 2014. I did not know NiMH goes bad 3 - 4 years. How did you find out this information? I have been using rechargeable batteries for years with no problems without NiMH. I just checked a different package of AAA purchased in January also & it says 2011. Gee your never too old to learn a valuable lesson. Thanks so much for informing me about this. Have a great day. VRLT

Yea mine went bad after a very short time also. I don't know why they didn't make it to use a AAA. I went to the battery store to get them. They cost $3.50 ea for those little things.

Since my review of these, I found out that the battery can be replaced. These advertise as having a 600mAH NiMH battery. Mine had a 400mAH battery. I opened the black box and replaced the battery with a larger strength battery at full charge and they now work great again. I don't think the sun is strong enough to indefinitely charge the battery. It needs to be fully charged in a NiMH battery charger (do not use NiCD- nickel cadmium). So far, these lights have been brightly glowing on my dining room table for the last 3 nights. It's worth a shot, since they truly are very pretty. I did learn that the higher the number on the NiMH battery, the longer the lights will function. I had a 1850 that I experimented with and it is working. Don't know if the sun strength and duration is good enough to recharge it. That's my next experiment. Hope this helped.

we're currently using recharbeables in our sets. They seem to work well, I haven't had to replace yet (just been playing a couple of times). Actually, I did have to replace almost right away - it turns out two of the 6 were not fully charged. The gun would still tag/receive tags, but the special effects were all off and the voice/sound effects were V...E...R...Y.......S...L...O...W... but it was a good warning, and at least I could finish that game effectively. If that's what we have to look forward to, I'm pretty happy with how the tagger handles low battery.

I have same problem, I took a flash light and shocked it at night to turn off then when lite was removed it seemed to reset, been working for a couple of day now, i have 3 of them 2 work great all the time one is exposed more to street lights and another porch lite, it seems to be effected by it. Im going to try a cover over the eye with an exposed end towards the sky.

Karl, Sorry I didn't notice your question eariler. Any 'value-charger' (such as this Duracell CEF14, Rayovac Easy charger, Sony BCG34HLD, etc) can be used to 'prime' a completely drained NiMH or NiCd cell. Just put it in the cheap charger for 1-2 minutes, and that should be enough for the BC-9009 to recognize it again. If the cheap charger requires charging in pairs, you can pair an empty cell with a full cell - as long as you don't forget and leave them in there for too long. If your question is: "Can I use a NiMH charger to recharge NiCd cells"? The answer is yes - if you know what you're doing. - Dumb timer-based charger expects the cell capacity of a typical NiMH to be higher (around 2500mAh). So if you put in a low-capacity NiCd cell and leave it overnight, the cell will be badly over-charged. This is not going to cause any danger, but it is bad for battery lifespan. If you can remember to remove the cells after a few hours, then it is still alright. - Smart charger like the Sony BCG34HLD looks for a voltage 'dip' (negative dV/dt) to terminate charging. The -dV/dt for NiMH is smaller than that for NiCd, which means any smart charger designed for NiMH can also handle NiCd, but not the other way around. I recommend the Sony value charger, because it is the only one that can recharge individual cells. Sony Cycle Energy BCG34HLD4KN Power Charger with 4 Pre-Charged 2000 mAh AA Batteries

My husband Chuck is a mechanic and he says it occasionally falls out of his shirt pocket without breaking. As long as it doesn't lamp tip first on the bulb it survives OK. When the light starts to flicker or seems dim, don't tap it or bang on it!Just replace the AAAA(4A) batteries right away. AAAA batteries are available at more stores than they used to be.Radio Shack has them. He is unsure of the lumens but it is plenty bright and the beam is concentrated enough for all uses. Chuck has used them for 5 or 6 yrs and bought 3 at a time because he loves them that much! My husband Chuck is a mechanic and he says it occasionally falls out of his shirt pocket without breaking.

High Flyer,I looked up the user manual for EV2653 cordless phone system. The manual says to charge the included 600mAh AAA cells for 12 hours prior to first use, but subsequent maintenance charge only takes 8 hours. Base on this info, I can safely conclude that it is a dumb charger with a constant current of 75mA.You should be able to use the eneloop 800mAh AAA cells in the handset just fine. However, since the handset is being charged daily, you don't really need low-self-discharge cells in it. Ordinary 1000mAh NiMH cells may actually do better since they can provide longer talk time for the women in the house... No wait, just stick to the eneloop cells in that case.

I doubt you can find any 2700mAh NiMH cell that can retain 75% of its charge after just ONE month of storage. Why don't you test it for yourself? Charge up a set of 2700mAh cells and keep it on the shelf for one month, then use it in your digital camera or flash light. Let us know how much battery life you can get out of it.

I've had very good luck with low self discharge NiMh AA batteries. You just want to make sure the batteries are all in good condition. One bad cell will reduce it a lot.

I bought a set of Tenergy 18650's and I let the headlamp run on low for 14 hours before I got bored and shut it off.not sure how much longer it would have gone.

Battery probably bad. If you let NiMH get absolutely flat (discharged) they CAN reverse polarity.

It works in 2-3 D and C cell Maglites It will not work in a 4 cell. There is a different version that works in a 4 cell though. Just search around a little bit and you should find one.

Not sure about damage, but my flashlight (FENIX) worked with those, but company recommended TENERGY 18650 rechargeable. One 18650 same size as two CR123s. TENERGYs hold charge longer. Should work for you, John, but email to your LEGACY company should confirm it for you.
