    Match those batteries with the correct application for best results

    The Energizer L91 Lithium AA cell is a fantastic power source. For high-drain applications, it offers great advantages over ordinary alkaline cell and rechargeable NiMH cell. However, it is also very expensive as a disposable battery. So it is important to recognize the strength of L91, and use it only in applications that give you the best results. Otherwise you'll be wasting your money.According to data sheet published by Energizer, the capacity of the Lithium AA cell (L91) is 3000mAh. This number remains nearly constant with load current. In comparison, the ordinary Alkaline battery (such as the ) is rated as 2800mAh, but only at a very light load of 25mA. At a heavy load of 1000mA (typical for a digital camera or flash unit), its capacity drops to below 1000mAh. This number gets even worse at low temperature... 5/5 NLee the Engineer (Nashua, NH) - See all my reviews, January 1, 2008

    Lithium AA batteries are NOT the same as Lithium-ion Rechargeable

    [Updated on June 8, 2011]Note: Amazon has moved two of my previous reviews (one for Energizer Lithium AA 4-pack, one for 8-pack) under one page. Therefore I have to update my review to add some new information - or else I look like a fool who says the same thing twice.=== New information follows ===There seems to be some confusion about those Energizer Lithium AA batteries. Several people have bought those batteries under the assumption that they are rechargeable, only to be disappointed later.Despite the name 'Lithium', those Energizer Lithium AA batteries are very different from the commonly known 'Lithium-ion' rechargeable batteries. Namely:- They are single-use batteries (NOT rechargeable like Li-ion)- The terminal voltage for each cell is around 1.65V (compared to around 3.7V for each Li-ion rechargeable cell)The two types of batteries are not compatible.

    First off, I did some research and 3400 mAh cells just came out costing about $17-20 EACH... 4000 mAh advertising is clearly false.

I know how to test batteries & I have the equipment. I tested these based on the standard slow 20 hour discharge rate, not a high rate which makes the batteries look even worse.This battery company is basically running something like a scam. I bought a total of 6 of these at 2 different times. My tests show that on average, they don't even measure up to a 1/3 of the 3000 mAh level claimed by UltraFire. One went totally dead after using only once.Furthermore, they only have about the same power level as found in a triple pack of AAA batteries.Therefore, buying these batteries makes no sense at all. Save yourself time & trouble & stay with lights that use the triple pack of AAA batteries.

    When you think China; Think... BUYER BEWARE!

    These chargers are junk! They are everywhere because they are cheap. I'm an engineer, and part of my job is to prep items for, and run items through UL and FCC testing. These are not only noisy, and out of tolerances for FCC emissions, but based on what I see; there is no way these chargers could pass UL testing. They are dangerous! The contacts where the AC terminals connect to inside are poorly designs, made of cheap material, and in some cases can bend and touch each other. There is no thermal, overload, or short circuit protection. Anyone who values their safety will not use these. If you must use these chargers DO NOT leave them unattended for any amount of time. This is true not just for this one, but all of the 18650 and 14500 chargers that look like this one. They are all made from the same design, and with the same chap materials. Buy a good charger...

    ULTRAFIRE is 100% unreliable

    This brand and manufacturer is 100% unreliable ... bought 4 flashlights from them pre-Sandy (the storm) ... used them during Sandy and they worked fine. Post Sandy ALL flashlights and batteries failed! As follows: 2 batteries simply starting leaking in the charger (also an Ultrafire charger) - tossed; 2 batteries never recharged again - tossed; 2 batteries charged only partially - tossed; 1 flashlight simply burned out (all LEDs) - tossed; 2nd flashlight partially burned out - main center LED which was generating most light - tossed; 3rd flashlight - never turned on again - on/off switch just stuck and would not disengage - tossed; 4th flashlight - constant flicker no matter what setting I put the on/off switch on - tossed. So let's do the math here: over $150 of essentially throw away flashlights, batteries and chargers for a one time event. No matter how you look at this it's a ridiculous proposition - next I am going back to Fenix - also equally expensive for just one but it lasted... 1/5 jackbnimble (New Jersey) - See all my reviews This review is from: 4pcs Ultrafire 18650 3000 mAh 3.7V Li-ion Rechargeable Battery+1pcs Charger (Electronics) This brand and manufacturer is 100% unreliable ... bought 4 flashlights from them pre-Sandy (the storm) ... used them during Sandy and they worked fine.

This review is from: 2Pcs 18650 3.7V-4.2V 5000MAH Li-ion Rechargeable Efficient Battery Deep Blue (Electronics) I ordered these to supplement my one battery I bought for my iTaste VTR. My first battery is an efest 2000mah. I bought these thinking "wow, 5000 may!" BUT using the same charger, same settings, each of these batteries only lasts about 2 hours. My original efest 2000 mah batter lasts 1.5 to 2 days with the same usage patterns. These batteries are either bad or misrepresented. Either way, I DO NOT recommend them. But I do recommend the efest brand based on the one battery I have that is 2000mah. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , July 6, 2014

Pleasant to deal with and prompt with their shipping. I have been trying to update this page for about 4 months and just figured out how to do it.

This review is from: EBL® 855 4 Bay 9V Li-ion Battery Charger with 4 Pack 600mAh 9V 6F22 Low Self-Discharge Lithium-ion Rechargeable Batteries (Electronics) I purchased this package because I go through a lot of 9volt batteries playing paintball. I have 2 battery operated hoppers, and they each take (2) 9volt batteries and I have an electronic trigger gun that runs on a 9volt. All in all, that is (5) 9volt batteries and under moderate to heavy use, I have to replace them every 3 months or so. That's $27 every 3 months. This 4 pack of batteries with the charger should save me quite a bit of money.I only gave them 3 stars because the overall size of the battery is a few hairs bigger than a Duracell or Energizer 9volt battery. I had to "convince" them to fit into the paintball hopper. It scraped some of the foil off of the batteries, but they fit and worked like a champ. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , September 30, 2013

They work alright, all four cells arrived neatly and on time but like all Chinese made non-name brand li-ion cells, these are terribly overrated.For name brand 14500 cells, you'll rarely find them over 900mAh and yet these are somehow 2000mAh? Lies.But they do work well in my flashlights, they provide plenty of juice and seem to be well made for the price I paid. With prices like this, I'm guessing these cells are anywhere from 700 to 900mAh in capacity.

This review is from: Aweek® 4Pcs 14500 2000mAh 3.7V Li-ion Lithium Rechargeable Battery AA Batteries For Cree Led Flashlight (Misc.) They work great. Comparing other reviews that fault this type of battery for capacity, I am not sure if they are actually 2000 mAh, but they seem to last as long as I need them. They are brighter in the CREE flashlights than using regular AA batteries (3.7v vs. 1.5v) plus they are rechargeable. They apparently have no protection circuit built in, but I am only using them for flashlights outside so it really doesn't matter. I am well familiar with using lithium-ion and lithium-polymer batteries in my radio control hobbies, so I charge them in my hobby station outside the house to be safe. So far, after several charges each, they have maintained their longevity, do not overheat while charging, and have been great for the intended purpose. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , March 16, 2015

I have a photo of what was shipped that I will place in the product image section.Please do yourself a favor and do not do business with these people or else risk ending up like me. I trust my grievance will be resolved with the Amazon A-to-Z Guarantee Program which I just filed. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , June 18, 2012

    Poor battery, and not for high current applications.

    I purchased two sets of Ultrafire 18650 3000mAh batteries with charger. The included charger works well for travel needs but does not seem to have two independent charging channels, as there is only one charge status LED. It works well enough for casual use with inexpensive cells in my collection, but a higher quality charger such as the Pila IBC is a good investment if you get serious and want the most out of your more expensive 18650 batteries.My only complaint is these batteries after being freshly charged cut out under a high load because of the protection circuit board which seems to be current limited to only around 2.5 Amps. For instance, when trying to drive a Ultrafire WF-502B or WF-501B flashlight with the 900 lumen Cree XML-T6 P60 LED drop-in on max power, it will only illuminate for a couple seconds and then cut off. Running it for a few minutes on medium power to partially drain the battery then allows it to run continuously on high power. The measured current... 1/5 XYZZY - See all my reviews Verified Purchase(What's this?)

    Waste of money

    I purchased these for a fenix tk 35 flashlight. Both batteries indicate fully charged in charger and charger shuts off. When put in flashlight the highest mode would not work. the light would turn on for a second and then shut off. This is what the flashlight does when the batteries start to die. My other AW and tenergy batteries will last me about 2 weeks of light intermittant use before the turbo mode will stop working. These wont work at all in turbo. High mode will work but I never left them in to see how long. I tried to charge them a couple of more times using a different charger but it was the same thing, charger would turn on then after about 1 min would indicate batteries fully charged then shut off. Contacted R-lsales via amazon and was given a address to send them to in California at my own expense. Shipping was going to be $12.00, cost of batteries were $15.00. Wasn't worth the trouble.

    Works, but doesn't live up to claims

    I purchased two sets of these batteries on different days from the seller "CREE Flashlight." The first set I received was defective -- the included battery charger LED turned went out after about a minute of being plugged in. I wasn't sure if the batteries were still being charged, so I pulled them off the charger and measured the voltage with my digital multi-meter. I plugged them back into the charger for an hour, and took another reading. One of the batteries remained the exact same, and the other actually lost .02 volts. I spoke with Amazon about getting a replacement and was asked to send this set back while another was shipped to me. I decided that I would keep the original set until I had the opportunity to compare them to the replacements (fully charged, of course) and would select the two best batteries from the set of four.I received the second set promptly (thanks, Amazon!) and put the batteries in the charger. It worked! About 45 minutes later I had two... 2/5 MacAck - See all my reviews Verified Purchase(What's this?)

lithium-ion battery Icon Ties

A lithium-ion battery (sometimes Li-ion battery or LIB) is a family of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge, and back when charging. Chemistry, performance, cost, and safety characteristics vary across LIB types. Unlike lithium primary batteries (which are disposable), lithium-ion electrochemical cells use an intercalated lithium compound as the electrode material instead of metallic lithium.
