Comments about Tenergy Tenergy LiFePO4 RCR123A, Rechargeable Lithium-Ion Battery, 3.0V, 750 mAh:

I use these batteries with my Streamlight PolyTAC LED in the security industry. The manual says not to use rechargable batteries, but who am I to pay attention to a manual? I've had these batteries in my flashlight over a month on two charges and the flashlight works perfectly. It's a great investment! ...unless you like spending all kinds of money on regular 123s :)

I work on military A/C in the Quality Assurance Division inspecting safety of flight items that have to be exactly perfect. During these inspections I must have reliable batteries and who wants to buy batteries for 5.00 a piece. Thank you for saving me so much money giving the quality our NAVY pilots deserve.

I use this product constantly and my only complaint thus far is after a few months of use they arent as potent on a full charge compared with a new set of them. Otherwise I would have spent a fortune on cr 123 batteries that are not rechargable.

Comments about Tenergy Tenergy LiFePO4 RCR123A, Rechargeable Lithium-Ion Battery, 3.0V, 750 mAh:

I use these batts in my polytec streamlight. Great light and great batteries to pair with it. life is a little short it seems, but not short enough to keep me from buying more. I bought em with a charger to just test the waters and make sure they would work with my light, and im impressed. I would recommend these to anyone using a good flashlight. New batteries are far too expensive for a 120 lumen light with an expected batt life of 3hrs.

Bottom line, buy em if youre using them in a similar light.

Comments about Tenergy Tenergy LiFePO4 RCR123A, Rechargeable Lithium-Ion Battery, 3.0V, 750 mAh:

I do aircraft maintenance and inspections at night and need a powerful flash light. the downside to using a poowerful flash light especially one that uses 123 batteries is that you go through a lot of batteries and the are expensive. These allow me to do my work without the concern of wasting batteries costing myself money. The only last about half as long as they have half the capacity but with just a few cycles they will pay for themselves and then some.

I use these batteries for an electronic vapor cigarette that helped me to stop smoking 7 months ago and I use it 24 hours a day so it's important to have a good product that works well that I can use all day and every day, also this was the best price I found for them anywhere online[...]. I was very pleased with everything to do with this purchase. Thank you.

Comments about Tenergy Tenergy LiFePO4 RCR123A, Rechargeable Lithium-Ion Battery, 3.0V, 750 mAh:

"Not sure if they are suitable for Xenon Flashlights."The above statement was taken from a review [...] I can state that they do not work well in an Xenon flashlight. I have a Cabelas light with the Xenon bulb and grew tired of buying the $10 batteries for it so I went with these rechargable batteries. I charged them, put them in and as soon as I turned the light on, the bulb blew instantly. Now if I want to keep this light, I have to pay $20 for a new bulb assembly. Love the light but I may just go back to a Maglight. I found the same batteries on availabe on another site and they list as being great for LED lights but not other bulbs. Wish I would have found that before I bought them. Probably good batteries and charger but they do not work well in non-LED flashlights. BTW, I hate LED lights. Not nearly as bright.

Comments about Tenergy Tenergy LiFePO4 RCR123A, Rechargeable Lithium-Ion Battery, 3.0V, 750 mAh:

I purchased these batteries to use in a xenon flashlight. Worked great right out of the package for several weeks. After charging and replacing them in Flashlight, the bulb blew instantly. After reviewing the specs on the batteries, it states they can reach a max. charge of 3.6 volts, which when combined in series could be enough to blow out a bulb. Not sure if they are suitable for Xenon Flashlights.

Comments about Tenergy Tenergy LiFePO4 RCR123A, Rechargeable Lithium-Ion Battery, 3.0V, 750 mAh:

I have a insight M3X I've had it almost a year and decided that it was time to get a rechargeable set of batteries. I was excited and once I got them and they had charged the allotted time I put them in an pop it blew my light bulb. Since I'd had it almost a year and heavily used it I wrote it off as it's time to go. So I put the replacement bulb in and immediatly it went pop dead light. Having fully charged batteries is great unless your lightbulb wont work.
