Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of rechargeable battery commonly used in consumer electronics. They are currently one of the most popular types of battery for portable electronics, with one of the best energy-to-weight ratios, no memory effect and a slow loss of charge when not in use.
HISTORY
The first workable lithium cells were created in the early 1970s at Exxon Central Research and Development. Lithium-ion batteries became a reality after Bell Labs report of a workable graphite anode. However, it took till 1991 for the first commercial version to be created by Sony to be available to the market.
PRO'S
-
Li-ion iPod batteries do not suffer from the memory effect.
-
Li-ion batteries are a lot lighter than other batteries since Lithium is the 3rd lightest element.
-
Li-ion batteries have a low self-discharge rate of approximately 5% per month, compared with over 30% per month in nickel metal hydride batteries and 10% per month in nickel cadmium batteries.
-
Lithium-ion batteries are more flexible for manufacturer's to form into a wide variety of shapes and sizes so as to efficiently fit in the available space in the devices they power.
-
Relatively low self-discharge - self-discharge is less than half that of nickel-based batteries.
CON'S
-
It is fragile and requires a protection circuit to maintain safe operation.
-
Can rupture, ignite, or explode when exposed to high temperatures or direct sunlight.
-
Rather than showing a gradual shortening of the running time of the equipment, Li-ion batteries may often just abruptly fail.
-
Expensive to manufacture.
-
Regulatory controls on transportation restrictions for shipment of larger quantities.
If my battery dies completely, will I loose my music or data?
No! Your music, data, video, and/or pictures are stored on the hard-drive and are completely independent of your battery.
When I replace the dead battery with a genuine Longlast Battery, do I need to recycle my iPod battery?
It is highly recommend recycling your battery. Batteries may produce the following potential problems or hazards:
-
Pollute the lakes and streams as the metals vaporize into the air when burned.
-
Contribute to heavy metals that potentially may leach from solid waste landfills.
-
Expose the environment and water to lead and acid.
-
Contain strong corrosive acids.
Staples and Radio Shack have free recycling programs throughout the United States. This Website will give you more information about recycling batteries: www.earth911.org
About Charging your Longlast Battery
Lithium-ion batteries pack in a higher power density than Nickel-based batteries. This gives you a longer battery life in a lighter package. You can also recharge a Lithium-ion battery whenever you want without worrying about memory effect. Memory effect is common in Nickel-based batteries that require a full charge or discharge cycle necessary to keep Nickel-based batteries at peak performance.
What is a "charge cycle"?
Lithium-ion batteries can be charged a certain number of times, as defined by charge cycle. A charge cycle means using all of the battery's power, but that doesn't necessarily mean a single charge. As an example, you could use to your electronics device for a few hours one day, using half its power, and then recharge it fully. If you did the same thing the next day, it would count as one charge cycle, not two. So theoretically you may take several days (or weeks) to complete one charge cycle. Each time you complete a charge cycle, it diminishes battery capacity slightly, but you can put your electronics device battery through many charge cycles (about 300-500) before requiring a new battery.
Should I always run my Longlast battery all the way down before recharging?
No, its best charge before it goes dead. If at that point you leave the devices uncharged for days and days, it could shorten battery life or make the voltage in the battery so low that it will not revive.
How long does it take to charge the battery?
Fully charging the battery takes about 4 hours, but is recommended over night. You can also fast-charge the battery to 80 percent capacity in 1 hour to 2 hours. Charging the battery may take longer if you're using iPod as it charges.
How do I charge my Longlast iPod battery?
The easiest way is to connect it to a Power Adapter.
Do I have to completely drain my Longlast iPod battery to the end before charging it to prevent the so-called "memory effect"?
You do not need to drain the battery before charging it. Lithium-based batteries you're your iPod has, does not have any of the memory effects that nickel-based rechargeable batteries have.
If I don't unplug after four hours on charge, will the battery start running down because the charger shuts off?
No, your iPod stops charging once your Longlast battery is full. But there is no need to take your iPod off the charger right away. However, if you turn off AC power to the charger but leave it hooked up, it could drain the battery. Best practice is to plug the iPod into the cable (or dock) and the cable into the charger, then plug the charger into the wall, otherwise problems maybe caused by the surge when you do it the other way around. After charging, we recommend to unplug it from the wall first.
If I wait to charge my electronics device until the battery is pretty low, will that save cycles and prolong battery life?
It's not how many times you charge it's how many charge/discharge cycles you complete that determines battery life. It makes no difference whether you fully charge a half-used battery twice, or a fully rundown battery once both count as one cycle in the estimated useful life of about 500 cycles. Waiting to charge merely postpones battery use it does not prolong it. So charge whenever is convenient.
Will I shorten the life of the battery if I don't charge my Longlast battery to 100% for the first charge?
No, although we recommend charging fully the first time, but generally after the first 4-5 hour charge, the lithium battery does not suffer from memory (which is mostly urban myth anyway) and will not be harmed by partial charges at any time.
Do I have to "condition" my battery before I get the full performance out of it?
This is somewhat correct, but it is not true that you have to charge the electronics device battery, run it down, recharge it again several times before using it to condition the battery. It is true that the first few charges (full or partial) will probably not result in as long total run time as later charges. So a brand new battery does not perform quite as well as one that has been used a bit.
Ok, everything looks great, what am I waiting for?
Good question! It's time to select your Longlast Battery to buy now!
