Article: Battery Info

This thread is dedicated to breifly explaining the different types of batteries that consumer items use.
[list]
Ni Cad
Ni MH
Li IOn[/list:u]


NiCad and NiMH:

NiCad (Nickel Cadium) is an older version of NiMH(Nickel Metal Hydride).
There are two major differences which are[list]
NiMH is about twice size of the NiCad.
NiMH is less likely to cause the effects of the memory effect.[/list:u]

Memory Effect: When using NiCAD previously, we were strongly suggested to making sure that battery was dead or almost(discharged) before charging again.Otherwise the life of the battery would severely decrease.
Previous mobiles used NiCad. I remember was a pain because I recall having to buy a new battery almost every month....

Lithim Ion:

I beileive can say that almost all consumer devices now use LiIOn. It does not suffer from the "memory effect" It is also lighter than NiMH and NiCad batteries ! This has definitely made a difference. Imagine cell phones like the Nokia 6 series (6310i) for example having a Nicad or NiMH battery.The battery on that phone is a large chunk of a portion of its physical shape.


According to http://www.atbatt.com/info/battery.htm, here are some ways to strenghen the life of your battery.

Prevent the Memory Effect:
Keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries which do not suffer from the memory effect.

Exercise the Battery:
Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new battery break in procedure described above.



The SEP800 uses Li-Polymer

The Lithium Polymer is a branch of Li Ion. One of the major attributes it holds over the Li Ion is its ability to produced much smaller than the Lio Ion. This type of attribute is high seeked by the latest mobile technology manufacturers. Even though one of its drawbacks is that it more expensive to produce compared to the Li Ion.

This concludes my article on Batteries.

Here are a few links that may interest you.

EEEEK!
You miss out on a few rather important issues there mate.
NI-CAD or NI-CD is extremely poisonous.

No memory effect my a**

No memory effect my a**. My mom got a laptop 3 years ago with Li-Ion, and it's completely dead now. My own laptop (18 months old, and which I always fully discharge and recharge) is beginning to get less battery life as well. And that one has Li-Ion as well!!

Re: No memory effect my a**

Man, that's got nothing to do with memory effect. A li-ion battery's usual lifetime is about 1000charge circles, approx. 2 years. As it approaches that, it looses it's capacity constantly, that's not memory effect.

Delta737... I was about to say what the Guest said.

Having no effects of the Memory syndrome does not mean that you battery will remain the same for ever...even assuming it sounds stupid..soorry for that..but its obvious. I think nothing virtually remains the same after alot of usage.Even simple stuff like my optical mouse is giving me trouble. I been using it for about 3yrs now. It kinda lags,skips.. even though its never been dropped..just sits there on its pad...
