Low self discharge battery, Minimum capacity 1900 mAh, Protection for Overcharge, Can meet HSF requirement.
Rechargeable batteries play an important role in our lives and many daily chores would be unthinkable without the ability to recharge.
Nickel-cadmium – Mature and well understood, NiCd is used where long service life, high discharge current and extreme temperatures are required. Nickel-metal-hydride – Serves as a replacement for NiCd as it has only mild toxic metals and provides higher specific energy.
Lithium-ion – Li-ion is replacing many applications that were previously served by lead and nickel-based batteries.
Table 1 compares the characteristics of the four commonly used rechargeable battery systems, showing average performance ratings at time of publication. Missing from in the list is the popular lithium-ion-polymer that gets its name from the unique separator and electrolyte system. Please tell me if Li Ion battery has what is called “memory effect” which means it has to be fully discharged before charging again?In other words,can it be charged as often as we want,like in between the usage so that battery charge does not go off during the use of the equipment? If I connected multiple super capacitors to replace a 12 volt car battery in sequence,  could I achieve enough power to start my engine, if so how many and what size capacitor. I believe they used to be used for low internal resistance applications but were unpopular because of the Potassium Hydroxide electroyite.
I see 18650 batteries with, for example, 30amp continuous discharge and 60amp pulse discharge. Question: Why do Li ion batteries cost so much more than other secondary (rechargable) batteries? By submitting this form, you are providing your express consent to receive electronic communications from Battery University.
Secondary Batteries (Rechargeable batteries) play an important role in our lives and many daily chores would be unthinkable without the ability to recharge an empty battery. Lead Acid Battery — This is one of the oldest & the most well-known rechargeable battery systems.
Nickel-cadmium (NiCd) Battery — This is used in applications which require a long service life. Nickel-metal-hydride (NiMH) Battery — Owing to many environmental concerns, NiCd batteries are being replaced by other types. The lithium-ion family is divided into three major battery types, which are named by their cathode oxides – these include cobalt, manganese and phosphate.
Lithium-ion-cobalt or lithium-cobalt (LiCoO2): This has high specific energy with moderate load capabilities and modest service life.
Lithium-ion-manganese or lithium-manganese (LiMn2O4): This is capable of high charge and discharge currents, but has low specific energy and modest service life.
Lithium-ion-phosphate or lithium-phosphate (LiFePO4): This is similar to the lithium-manganese system.
Recent developments include batteries with embedded electronics such as USBCELL, which allows a user to charge an AA battery through a USB connector. The technology behind nickel-zinc (NiZn) batteries has been available for ages, however making it cost effective and affordable for end users is something that has happened in the last few years. Another important thing to note regarding the NiZn rechargeable batteries that is related to their higher voltage is that when using these in a device that has an indicator of the remaining charge of a battery the indication may not be accurate. Anyway, in general we suggest that you do not bother with NiZn rechargeable batteries at all as a the moment these are being sold mostly under various Chinese no-name brands, so the risk of having trouble with the reliability of the batteries or the charger for them is higher. These batteries have a lot going for them: they come fully charged (like alkaline batteries), and they can hold their charge over many months (unlike regular Ni-MH rechargeables). The charge times are as follows: AA Eneloops charge in 230 minutes, and AAA Eneloops charge in 135 minutes.
How about some good battery chargers to go with these batteries?A The chargers featured below are some of the smartest out there — they have built-in protection to prevent overcharging or undercharging. The drawback is that the single-status LCD panel a long programming sequence makes it a bit difficult to use for multiple cells.
Maha’s chargers can restore batteries to their optimal performance level by repeatedly charging and discharging them.
Does ‘Eneloop’ supply rechargeable 9volt pps batteries and the appropriate charger? If I use an item once per week(like a beard trimmer) for 10 minutes, should I use rechargeable AA Nimh LSD batteries(like Eneloop, Eneloop Pro or Energizers)? Do I have to completely run out a rechargeable battery before I can charge it again, or can I charge it when I want?
I usually do buy packs of 4 and run several cycles in an old fashioned flash light just breaking them in.

Personally I would go with the Maha PowerEx a€?Ultimate Professionala€? Charger, It will charge lots of kind of batteries for any use.
Battery Polarity Reversal Protection – Prevents Charger damage and operation in case a battery is inserted into the MH-C808M backwards. Alkaline battery Protection – Automatically recognizes an Alkaline battery and Prevents Charger operation and damage. Yes, the newer NiMh batteries have a longer shelf life, and are generally more reliable than the older kinds.
I use rechargeable batteries in every device in my home (requiring batteries), and I don’t have any issues. I use Eneloops with my XBox 360 Wireless controller hooked up to my PC, no problems whatsoever. If the eneloop are the best batteries why doesn’t Panasonic have it’s own top rated charger? Over time I’ve seen a number of battery manufacturers recommend using their chargers only with the batteries they produce. What do you think about SunLabz 2800 mAh AA batteries and their associated smart battery recharging counterpart? I fly RC Helicopter’s almost daily and I have tried many generic rechargeable batteries but nothing compared to the Eneloop. I just can’t say enough positive things about Eneloop rechargeable batteries but try them for yourself.

Lead acid is rugged, forgiving if abused and is economically priced, but it has a low specific energy and limited cycle count. NiCd is one of the most rugged and enduring batteries; it is the only chemistry that allows ultra-fast charging with minimal stress.
Li-ion is divided into different types, named by their active materials, which are cobalt, manganese, phosphate and titanate. Battery University monitors the comments and understands the importance of expressing perspectives and opinions in a shared forum. I think it would be really worth to add a little bit of today’s so popular lithium-polymer (LiPo) and mention also a chemistries like lithium-sulphur (LiS) and lithium-air as well.
In this regard, there are different types of secondary batteries that vary in their specific energy, life, load characteristics, safety, price, self-discharge, maintenance requirements, and disposal. Other characteristics of NiCd batteries include high discharge current, extreme temperatures and economical price.
So a few years ago the first consumer oriented rechargeable NiZn batteries in popular sizes such as AA and AAA started appearing on the market and though there was initial interest in them now, a few years later, we can say that they did not come to stay. So generally the cost of just a few NiZn batteries is not going to be justified when you add the cost of the special charger you need to get along with the batteries, however if using more batteries than the things will balance out. Because of the higher voltage the NiZn batteries may be reported as full or almost full while at the same time you might be actually close to having them almost fully discharged especially if the device you are using them in is designed for Alkaline batteries. They have a high energy capacity (2500 mAh), and they perform better than similar high-capacity AAs. Because they can hold their charge for so long, they are suitable for low-drain devices like remote controls and flashlights. I do not recommend the Energizer or Duracell rechargeable batteries — these name brands seem to produce inferior rechargeables, perhaps to protect their sales of alkaline batteries. Eneloops can be recharged up to 2100 times, and they will retain their charged capacity even after years of storage. The Eneloop Pro has a capacity of 2500 mAh –this is 500 mAh more than the regular Eneloops.
I then meter each battery after being fully charged INDIVIDUALLY and match the closest batteries as a pairs. A good quality charger will revive and recondition your batteries, and they will indicate if a battery is malfunctioning, which is quite useful. I just have a few questions, will this work on Xbox 360 wireless controllers or are these high powered, and for the charger do I need to purchase a separate one or will the kit(if there is one) be okay since I won’t be doing heavy use for it, just mostly for gaming and for some torch lights at home.

Unlike traditional Alkaline or Lithium batteries, these rechargeable batteries can be charged and reused up to 500 times, saving you money and reducing waste.Vivitar Ni-MH rechargeable AA size batteries hold their charge longer than the competitors' NiMH rechargeables when not in use, and thanks to their 2100 mAh rating, are perfect for use in high drain devices like digital cameras too.

Lead acid is used for wheelchairs, golf cars, personnel carriers, emergency lighting and uninterruptible power supply (UPS). It is more expensive than most other batteries, but high cycle count and low maintenance reduce the cost per cycle over many other chemistries. Also missing is the rechargeable lithium-metal, a battery that, once the safety issues are resolved, has the potential of becoming a battery choice with extraordinarily high specific energy and good specific power. However, all communication must be done with the use of appropriate language and the avoidance of spam and discrimination. We recommend posting your question in the comment sections for the Battery University Group (BUG) to share. For example, the peak load current and best result range of Lithium ion battery chemistries is vastly superior to other types.
Lead acid is used for wheelchairs, golf cars, personnel carriers, emergency lighting and uninterrupted power supply (UPS) systems.
Li-ion batteries are more expensive than nickel and lead acid systems, and need protection circuit for safety. The main idea behind NiZn cells is that they are able to provide higher operating voltage than the rechargeable NiMH batteries, a voltage closer to the one of the Alkaline batteries, but with the ability to recharge them.
However, they are ideal for use in high-drain electronic devices like digital cameras, where they out-perform alkalines.
Their only potential downside is that they can be charged 500 times — not 2100 times like the regular Eneloops. You can mix and charge AA, AAA, C and D sized cells at the same time on individual charging circuits. For digital cameras (like my 10 year old Canon Powershot 540) they have lasted well over their rated 600 cycles. The charger *does* has short-circuit protection, over charge protection and reverse polarity protection. Do I need to get a more up to date charger for the batteries you have currently recommended?
Due to environmental concerns, NiCd is being replaced with other chemistries, but it retains its status in aircraft due to its good safety record. The table only addresses portable batteries and excludes large systems that resemble a refinery.
The sealed Valve Regulated Lead-Acid (VRLA) Battery  is popular in the automotive industry as a replacement for the lead–acid wet cell.
However, on average most people will charge their batteries about 100-200 times over a 5 year period. After so-so life from the Harbor Freight specials (usually 4-500 of their advertised 800 cycles), I’m getting 3+ years and maybe 800+ cycles from each pair and have taken about 20,000 shots and 500 hours of video. The better chargers will recondition the batteries, and they allow you to weed out the problematic batteries easily.
Also, within the Li-ion group, the cobalt system is different from Manganese and Phosphate. The VRLA battery uses an immobilized sulphuric acid electrolyte, reducing the chance of leakage and extending the shelf life.
If here is no power regulator in a device it will use the higher voltage that NiZn provides, so for example a flashlight may be brighter or a remote control car can run faster than with NiMH or Alkaline batteries.
On the other hand the newer Low Self-Dicharge NiMH batteries are with a significantly lower self discharge rate and NiZn batteries do not yet have an LSD version. Have in mind though that even if comparing mWh ratings of different batteries there are also other factors that need to be taken into account as well, so while it might be better to be used instead of mAh ratings it is still not be that accurate for comparison. For example, if you charged your batteries twice a week consistently, it would take 5 years to reach 500 charges. Panasonic recommends keeping the batteries in a cool location to maximize charge retention. After 5-6 cycles, I get a solid full charge in them and meter test again for matching up pairs. The problem is that this can lead to the reduced life of the light bulb of the flashlight as well as overheating the motor in an RC car and thus damaging it, so again you should be careful with the higher voltage of NiZn batteries. Also note that the more the number of batteries being used in a device, the higher the chances are that you might have trouble because of the higher voltage that NiZn batteries use. With one or two normally there should not be problems, but going for four or even eight batteries in a device the increase in the total voltage over what Alkaline or NiMH batteries will provide can be quite high and a cause a problem in some devices.
