9 Advantages Of Lithium Ion Battery
 
03:00
1. High energy density:   The much greater energy density is one of the chief advantages of a lithium ion battery or cell.  2.  Smaller and lighter: Li-ion battery is lighter than other rechargeable batteries in consideration of battery capacity. 3. Lithium ion cells is that their rate of self-discharge is much lower than that of other rechargeable cells such as Ni-Cad and NiMH forms. 4. Does not need prolonged priming when new. One regular charge is all that's needed. 5. Low maintenance:   One major lithium ion battery advantage is that they do not require and maintenance to ensure their performance. 6. Quick charging: Li-ion battery is quicker to charge than other rechargeable batteries. 7. Variety of types available:   There are several types of lithium ion cell available. This advantage of lithium ion batteries can mean that the right technology can be used for the particular application needed. 8. Specialty cells can provide very high current to applications such as power tools. 9. Longer lifespan: Li-ion battery can typically handle hundreds of charge-discharge cycles. Some lithium ion batteries loss 30 percent of their capacity after 1000 cycles while more advanced lithium ion batteries still have better capacity only after 5000 cycles.

LiFe safer than LiPo?
 
06:49
Are LiFePO4 batteries really safer than LiPo batteries, especially when used in RC transmitters? Well if abused, they do puff, just like a lipo, but after I spent some time trying to resuscitate a puffed LiFe transmitter battery, I eventually decided to subject it to significant electrical and physical insult -- to see if I could make it vent flame and smoke like lipos do. As you can see in the video, although two of the cells were charged and significant current was forced into the faulty cell, it did not ignite -- although the wiring did burn for a short while. Perhaps not totally conclusive but a pretty good indicator that LiFe packs are safer than lipos -- although the number of lipo-related transmitter fires remains very, very small.

"Free Energy" cell batteryLithium sulfinyl chloride accumulators which appeared in recent years combine the compact size of nickel cadmium batteries and nickel-metal-hydride batteries and a high capacity of lead-acid batteries."Free Energy" battery produced by the "Center of independent supply sources" is one of the variants of standby battery of this type. They are composed of PMX165C cells with a nominal voltage of 3.93V per cell, the capacity of 6.2 A/h and the size 24*55 mm.The peculiar feature of these cells is a relatively low discharge current about 0.3A. Therefore they can't be used in transport vehicles or power electric tools unlike lithium-iron-phosphate cells.Although these cells as supply source of independent devices have a wider temperature range from -20 to +165 degrees and low self-discharge current not more than 3% of the capacity per year.Moreover, "Free Energy" batteries have an inbuilt unit of discharge control which monitors the discharge level and sends reports on its status to the remote unit of data reader via Bluetooth or PC cable.All these characteristics make "Free Energy" batteries a reliable supply source for independent high-duty equipment.

Different types of Lithium Ion Battery
 
07:54
Friends a new video. Its about different types of lithium ion battery. Don't forget to subscribe and Press the like button if you wish. A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell. Lithium-ion batteries are common in home electronics. They are one of the most popular types of rechargeable batteries for portable electronics, with a high energy density, tiny memory effect[9] and low self-discharge. LIBs are also growing in popularity for military, battery electric vehicle and aerospace applications.

http://www.PortableSolarPower.Biz http://www.portablesolarpower.biz/products/lfp-20-portable-solar-power-generator-system This is a video going over the LFP 20 Portable Solar Power Generator System showing how it works and how to get the most out of it. What Is LIFEPO4? The Benefits Of Using LIFEPO4 Batteries. - + Safe Technology - Will not catch fire or explode if damaged. + Half the weight of an equivalent capacity lead acid battery. + Over 2000 deep discharge cycles vs. 300 for lead acid battery. + Double the usable capacity of lead acid batteries. + Virtually flat discharge curve means no "voltage sag". + High discharge & recharge rate capability. + They can be left partially charged for long periods of time. + Extremely low self discharge rate unlike lead acid batteries. + Does not suffer from thermal runaway like Li-Ion or Li-Po + Can be safely used with no loss in performance up to 140F. + Absolutely maintenance free for the life of the battery. + Does not contain any toxic heavy metals like lead & cadium. + The most eco friendly battery chemistry available. What Is MPPT Solar Tracking? - The most widely known advantage is an increase in useable power going into your batteries from a photovoltaic array. When a photovoltaic module is connected in a system which has a battery, the battery acts as a limiter to the voltage output of the array. A MPPT charge controller "fools" the panels into producing a higher voltage by "eliminating" their view of the battery in the system. This way they operate on their maximum power point voltage. This allows more power to go into the battery, up to 30% in some instances. Reports from the field indicate that increases of 20 to 30% in total daily solar power harvest are typically observed by using MPPT solar tracking technology vs. systems lacking MPPT technology.

A brief lithium ion booster discussion - Harbor Freight "Viking" booster
 
09:37
This video is the second part of a brief discussion of a lithium ion automotive battery jump-start booster I recently bought at Harbor Freight, the Viking Lithium Ion booster number 62749. A couple of corrections: Lead acid batteries typically self discharge at a rate of 1% per day, not 1% per month. Sorry, non-scripted video, will try to edit this change into future revision. Note that the weight comparison mentioned was to the jumper cables people typically carry in their car anyway. A typical lead acid based booster weighs 20 to 40lbs or more. I will edit the video for clarity on this issue. Check back on this channel for a re-edited version of the same video including the preceding material, as well as some other video where I test the claimed output and capacity.

Measuring Lithium Ion Battery Internal Resistance (ESR) to quickly identify bad cells.
 
04:28
I've recently stubled across a channel called Nerdville - The Nerdville chap has a mountain of 18650 Lithium Ion cells (About ~7000 of them). Having watched his plans for building an automated charging/discharging/measuring solution, I had an idea for a possible way to quickly identify bad cells before the lenghty charge/discharge cycles begin that I thought I'd share. The milliohm reading this technique gives will be wildly inaccurate due to using the wrong test frequency (100Khz instead of 1Khz), but relative measurements from one battery to another will be consistent.

About mobile battery malayalam, ബറ്ററിയെ കുറിച്ചുള്ള സംശയങ്ങൾ
 
05:35
Special thanks to Mr. Jayaraj G Nath https://www.youtube.com/user/jayarajgnathvideo About mobile battery malayalam,ബറ്ററിയെ കുറിച്ചുള്ള സംശയങ്ങൾ Lithium-ion batteries are common in home electronics. They are one of the most popular types of rechargeable batteries for portable electronics, with a highenergy density, tiny memory effect and low self-discharge. LIBs are also growing in popularity for military, battery electric vehicle and aerospaceapplications.For example, lithium-ion batteries are becoming a common replacement for the lead–acid batteries that have been used historically for golf carts and utility vehicles. Instead of heavy lead plates and acid electrolyte, the trend is to use lightweight lithium-ion battery packs that can provide the same voltage as lead-acid batteries, so no modification to the vehicle's drive system is required. Chemistry, performance, cost and safety characteristics vary across LIB types. Handheld electronics mostly use LIBs based on lithium cobalt oxide (LiCoO 2), which offers high energy density, but presents safety risks, especially when damaged. Lithium iron phosphate (LiFePO 4), lithium ion manganese oxide battery (LiMn 2O 4, Li 2MnO 3, or LMO) and lithium nickel manganese cobalt oxide (LiNiMnCoO 2 or NMC) offer lower energy density, but longer lives and less likelihood of unfortunate events in real world use, (e.g., fire, explosion, ...). Such batteries are widely used for electric tools, medical equipment, and other roles. NMC in particular is a leading contender for automotive applications. Lithium nickel cobalt aluminum oxide (LiNiCoAlO 2 or NCA) and lithium titanate(Li 4Ti 5O 12 or LTO) are specialty designs aimed at particular niche roles. The newer lithium–sulfur batteries promise the highest performance-to-weight ratio.

What is NICKEL-ZINC BATTERY? What does NICKEL-ZINC BATTERY mean? NICKEL-ZINC BATTERY meaning - NICKEL-ZINC BATTERY definition - NICKEL-ZINC BATTERY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ A nickel–zinc battery, abbreviated NiZn, is a type of rechargeable battery similar to NiMH batteries, but with a higher voltage of 1.6 V. Larger nickel–zinc battery systems have been known for over 100 years. Since 2000, development of a stabilized zinc electrode system has made this technology viable and competitive with other commercially available rechargeable battery systems. Unlike some other technologies, trickle charging is not recommended. In 1901 Thomas Alva Edison was awarded U.S. Patent 684,204 for a rechargeable nickel–zinc battery system. The battery was later developed by the Irish chemist Dr. James J. Drumm (1897–1974), and installed in four two-car Drumm railcar sets between 1932 and 1948 for use on the Dublin–Bray railway line. Although successful, they were withdrawn when the batteries wore out. Early nickel–zinc batteries provided only a small number of discharge/recharge cycles. In the 1960s nickel–zinc batteries were investigated as an alternative to silver–zinc batteries for military applications, and in the 1970s were again of interest for electric vehicles. Evercel Inc. developed and patented several improvements in nickel–zinc batteries, but withdrew from that area in 2004. Nickel–zinc batteries have a charge/discharge curve similar to 1.2 V NiCd or NiMH cells, but with a higher 1.6 V nominal voltage. Nickel–zinc batteries perform well in high-drain applications, and may have the potential to replace lead–acid batteries because of their higher energy-to-mass ratio and higher power-to-mass ratio — as little as 25% of the mass for the same power. NiZn are cheaper than nickel-cadmium batteries, and are expected to be priced somewhere between NiCd and lead–acid types. NiZn may be used as a substitute for nickel–cadmium. The European Parliament has supported bans on cadmium-based batteries; nickel–zinc is a good alternative for power tools and other applications. A disadvantage is increased self-discharge rate after about 30 cycles, so that batteries do not hold their charge as long as when new. Where this is not a problem NiZn is a good battery choice for applications requiring high-power and high-voltage. If used properly NiZn batteries can last for hundreds of cycles. Compared with cadmium hydroxide, the tendency of zinc hydroxide to dissolve into solution and not fully migrate back to the cathode during recharging has, in the past, presented challenges for the commercial viability of the NiZn battery. The zinc's reluctance to fully return to the solid electrode adversely manifests as shape change and dendrites (or "whiskers"), which may reduce the cell discharging performance or, eventually, short out the cell, resulting in a low cycle life. Recent advances have enabled this problem to be greatly reduced. These advances include improvements in electrode separator materials, inclusion of zinc material stabilizers, and electrolyte improvements (e.g. by using phosphates). PowerGenix has developed 1.6 V batteries with claimed battery cycle life comparable to NiCd batteries. Battery cycle life is most commonly specified at a discharge depth of 80 percent of rated capacity and assuming a one-hour discharge current rate. As the discharge current or the depth of discharge is reduced, the number of charge-discharge cycles for a battery increases. When comparing NiZn to other battery technologies, cycle life comparisons may vary depending on the discharge rate and depth of discharge used. Nickel–zinc cells have an open circuit voltage of 1.85 volts when fully charged, and a nominal voltage of 1.65 V. This makes NiZn an excellent replacement for electronic products designed to use 1.5 V alkaline primary cells. Equipment designed for alkaline batteries will not operate properly below an endpoint voltage based on 1.5V when fresh; NiCd and NiMH both have nominal cell voltages of 1.2 V, and will reach this endpoint before they deliver all their charge they are capable of.
