10 best li ion rechargeable batteries

Lithium-ion (Li-ion) rechargeable batteries are a type of rechargeable battery commonly used in various consumer electronics, including but not limited to coin button cells, household batteries, and other household supplies. They have gained popularity due to their high energy density, longer lifespan, and the absence of memory effect, which means they can be recharged at any state of charge without negatively affecting their performance. Here are some key points about Li-ion rechargeable batteries:

Composition: Li-ion batteries consist of a cathode, an anode, and an electrolyte. The cathode is typically made of lithium cobalt oxide, lithium manganese oxide, or other lithium-based materials, while the anode is commonly composed of carbon. The electrolyte is usually a lithium salt dissolved in a solvent.
Energy Density: Li-ion batteries offer a high energy density, which means they can store a significant amount of energy in a relatively small and lightweight package. This property makes them ideal for portable electronic devices like smartphones, laptops, and digital cameras.
Rechargeability: Li-ion batteries are rechargeable, and they can be recharged hundreds to thousands of times before their capacity starts to degrade significantly. This makes them cost-effective and environmentally friendly compared to disposable batteries.
Self-Discharge: Li-ion batteries have a relatively low self-discharge rate, which means they can hold their charge for extended periods when not in use.This makes them suitable for applications where long-term storage is required.
Safety: While Li-ion batteries are generally safe, they can be prone to overheating and, in rare cases, even catch fire or explode if they are punctured, exposed to extreme temperatures, overcharged, or damaged. Manufacturers incorporate safety features like thermal protection and voltage cutoff to minimize these risks.
Voltage and Capacity: The voltage and capacity of Li-ion batteries can vary depending on the specific application. Coin button cells typically have a lower capacity and voltage compared to larger Li-ion batteries used in household electronics. The voltage of a single Li-ion cell is around 3.6 to 3.7 volts.
Charging: Li-ion batteries require a specific charging regimen to ensure their safety and longevity. Overcharging or fast charging beyond recommended limits can lead to reduced battery life and safety risks.
Environmental Impact: Li-ion batteries are more environmentally friendly than disposable batteries because they reduce the number of batteries disposed of in landfills. However, recycling programs for Li-ion batteries are essential to minimize their environmental impact further.
Applications: Li-ion batteries are used in a wide range of applications, from small devices like watches and calculators (coin button cells) to larger household electronics such as cordless phones, laptops, tablets, and even electric vehicles (EVs).
Advancements: Research and development in Li-ion battery technology continue to improve their performance, energy density, and safety. New materials and designs are being explored to push the boundaries of what Li-ion batteries can achieve.

In summary, Li-ion rechargeable batteries are a versatile and widely used power source in various consumer electronics and household devices due to their high energy density, rechargeability, and other favorable characteristics. Proper handling, charging, and disposal are essential to ensure their safety and longevity.

User questions & answers

Question:	Will they fit and work in a streamlight tlr 2 hl? Also how long do they last competed to streamlight cr123 batteries
Answer:	I don't know if they fit streamlight but if it takes the CR123A batteries then it should fit. I don't know if streamlight is like surefire but I ran into issue with rechargeable batteries burning out the bulb my fix on that was ordering LED bulb off Amazon. I have been extremely happy with both batteries and bulb. I just purchased about two weeks ago so not sure about how long they last. I have been using for the last week on and off and still holding a charge.
Question:	Will This work in a Surefire flashlight tube? If so, how effective is the light output
Answer:	Will work, but life is not as long.
Question:	Can i buy a separate usb charger for these? (*aside from the one included
Answer:	No you have to use the included charger. I have a professional level Sky Rc MC3000 cylindrical battery charger that I charge all of My cylindrical style batteries on. With that being said not even that will charge these batteries there is a low voltage battery protection circuitry in the top of the battery it may do other things as well but it is why you cannot charge them on a regular charger. The charger it comes with is kind of convenient You don't have to lug around a larger big charger to charge these batteries You simply use the USB charger that comes with the batteries. I must say it charges the batteries so far from what I've seen good they're red while they're charging on the tips of the battery and then the tip of the battery turns blue when it's charged. One thing I can definitely say is these batteries are far better far more powerful and longer lasting than any nimh/ni-cad rechargeable battery I have ever used. There may be better lithium batteries out there It just all depends on how much you want to spend. For the price and these are pretty darn good and convenient to use lithium batteries. Hope that helps If any other questions don't hesitate to ask.
Question:	are these batteries the same as cr123a
Answer:	These are NOT like CR123a batteries. Due to the micro USB these batteries are overall longer by a few millimeters. This extends the button top past the standard size for CR123a. These will work in flashlights that have low tolerances in the tube.

Question:	Does this battery have protection to prevent over charging and under charging
Answer:	Dear Mark,Thanks for your question.There are over charge / over discharge protection circuit inside our battery.And there is overcharge protect circuit inside our AC-DC charger. So don't worry about overcharge/overdischarge .Best Regards
Question:	Can I use car cigaret socket to charge this battery pack
Answer:	Please Note - you cannot just plug it into a cigarette lighter to charge the battery pack. It requires a regulated 12.60 volt power supply. If you exceed this voltage you WILL damage the battery pack. Lithium-ion ICR cells do not tolerate over voltage charging above 4.2 volts per cell and will overheat and vent. The cells in these battery packs are not IC protected cells. These battery packs consist of 6 Samsung ICR1860 cells in a parallel series configuration and they do work great but To charge it from your vehicle or any other source you will need a 12.60 volt regulated output power supply. Caution- Warning..... Please be careful! I work with lithium-ion battery packs all the time. Under certain conditions you can create a fire so be careful! As an additional note- this pack is falsely advertised as a 6000mah pack - it is actually a 5400mah pack as the cells are Samsung ICR18650- 2700mah cells in parallel.
Question:	what is the max power draw for a 5v device? Can it deliver 3 or 4 Amps
Answer:	Dear Benoit,Thanks for your question.Max. power draw of our battery is 2A @ 5v and 3A @ 12v.Best Regards,

User questions & answers

Question:	Is this compatible with a vape
Answer:	I purchased the white label 1900mAh batteries and black labeled 2000mAh batteries several years ago. Contrary to other's comments, the white batteries are still charging up to full capacity, and the black batteries have all lost significant capacity. White labels say "made in japan" and black labels "made in china". Mfg Date of black batteries is AUG2014, and white batteries have "201409" imprinted. These have all been charged in the same MH-C9000 WizardOne from the beginning.
Question:	are these bigger than AAs
Answer:	1a would be .5 C with these 2000mah cells.. I checked the IR of these cells and with my Turbo Matched 30 from Competition Electronics (these are a 1500 dollar cell matching system that we professional RC on road and off road car and truck guys used to match cells. Very important and HIGH TECH for the time system. Was made for Nicd cells but worked equally well on Nimh cells when they came out) and matched them to get well matched pairs for practice cells for Mod Mini Z cars and boats.. I used Enloop cells for race days and practice with these.. these cells give a solid 2050 to 2100mah handle, will give me long run times and with cells matched with a 6 amp discharge will give me a avg voltage of about 1.02v per cell over 25 minutes, my well massaged Eneloop 2kMah cells i match at 8.5 amps they give me a avg May of 1980 to 2020mah and will hold a avg Voltage of 1.06V per cell at 8.5 amp load over 25 minutes. Point is these cells are a very good value, even in high load usage these cells stand up a lot better then similarly priced Nimhs from other brands.. these cells offer 85% the performance of Eneloop at less then half the cost.. the cells hold up well until about 200 cycles then they deff start to have noticablly lower avg voltage over time at the same discharge curve.. but that's in higher load apps then most people will be using them for.. I charge these cells at .75C or 1.5 amps, at 1.5 amps the cells are slightly warm off the charger and that's how I want them, slightly warm when ready to run as the IR will be lower with a warm cell over a room temp one giving me less voltage sag as the cell warms up under load... These cells will be slightly above ambient temp of charged at .5C or 1 amp, the warmth will start to happen once the cell reaches about 90^% full charge and progressively get warmer until peak charge.. at .75C charge or 1.5 amps you will notice the cells are a fair bit warmer then ambient temp and this has it's use for high load apps like my Mini Z's and some times I'll even charge them at 1C or 2 amps.. that will make for a fairly hot pack BUT will give me the highest voltage under load for the first 25 to 30% of the charge... but will ABSOLUTELY shorten the cells life and I would not recommend doing that UNLESS you know what you are doing to the cell and understand the cells life will be cut by good bit.. meaning if I get 200 really good cycles on a set of cells when charging them at .75C or 1.5 amps, moving to a 1C or 2 amp charge will know it's really good cycles life down to 100 to 125... but you will have less voltage sag/higher voltage under load taking the very warm cells off the charger and straight to using them then if you was to charge them at a lower rate and have cooler cells... Charge at 1 amp and you will be happy with these cells .5C and under will give you the longest cell life for sure..
Question:	With this work for my atomic beam flashlight
Answer:	Amazon keeps switching up the game to keep us guessing. As of 7/20/2019, the black label/green top batteries are definitely made in CHINA not japan (just received some, and I'm sending them back). None of Amazon's descriptions state whether or not either the black, silver, or white batteries are made, so I would assume that they are all Chinese at this point, which implies all of the manufacturing, quality, and supply chain issues Chinese batteries are famous for at this point. Do yourself a favor and spend a few extra dollars for eneloop or energizer, etc.
Question:	will these work in my solar lights that came with 18500, 850 mAh, 3.2 volts
Answer:	Updated on April 4, 2015To clarify, there are now three different versions of AmazonBasic rechargeable NiMH batteries:- The original AmazonBasics batteries came in black wrappers. They are made in China and have the capacity rating of 2000mAh. They are NOT as good as Sanyo eneloop batteries.ASIN:B0030T1NEA AmazonBasics AA NiMH Pre-Charged Rechargeable Batteries- The second version of AmazonBasics batteries came in white wrappers. They are made in Japan and also have the capacity rating of 2000mAh. They are (according to me) rebranded 2nd-gen Sanyo eneloop, so you can expect at least 1500 cycles lifespan.ASIN:B00CWNMV4G AmazonBasics Pre-Charged Rechargeable Batteries- The third version is also black but called 'high-capacity'. They are (according to me) rebranded Sanyo XX. They are rated 2400mAh, but actual capacity is around 2550mAh, just like Sanyo XX. The rated lifespan of the XX is only 500 cycles.ASIN:B00HZV9TGS AmazonBasics High-Capacity Pre-Charged Rechargeable Batteries
