Lithium batteries...

Ok, I know it's not a subject header designed to grip folk, but nevertheless...

(the following relates to the battery I will receive with my N73 tomorrow, hence this forum)

I was discussing something with a friend a long time ago, with regards mobile phone batteries, and he pointed out a major problem was with something I later found out was called 'memory loss' - IE, if you didn't charge or discharge fully, and became slightly irregular with phone battery use, you could essentially make the battery rather impotent, and it would suffer from less charge life, in both recharge numbers and length of each charge's duration.

I found out he had actually been meaning Nickel batteries, given this isn't an issue with Lithium, but it still begs a question about Lithium ones too:

I have seen quite a few guides which swear by giving your brand new Lithium battery a 14 hour charge for the first two charges, because although they're more than operable after about an hour, it's pretty much only around 50-70% charged, and the more 'outer area' cells in the battery have yet to be charged, meaning, if you don't give the full duration for those first two or so charges, you permanently reduce the battery's capacity given those outer cells become redundant.

*gasp for air*

HOWEVER, the manual for most phones I've seen recently simply advocate a 4 hr charge from the first charge onwards, or indeed a charge till the 'battery charged' message appears. Would this not ruin the battery?

What I am asking is:

What is the best way to get the absolute maximum capacity from your Lithium battery?
 
ppl are saying everything that i donno which is right, charge every night, charge only when the battery dies...blah blah~

imo charge every night.
 
I've used this as a reference a few times:

Battery University

I use my N73 probably 3-6 hours a day between calls, texting, browsing, etc. I don't listen to music through it. Just starting with SmartMovie, so that might add an hour or two a day to usage. I go through the battery every 1.5 to 2 days to about a 1/3, and then recharge.

If you are worried about this, buy a spare along with the desk charger. I've had to do that in the past with a Moto phone (before Li-Ion). It's only about 10% more on the overall price on the phone....

Enjoy your new toy. I'm still facinated with mine!
 
my back ground as a hobbygrade rc cars person, its general rule of thumb for lipo batteries is dont let them die down all the way: in rc car lipo batteries theres a sensor in most prefabed lipo batteries that sences voltages and what ammount of charge is in the battery, if the battery drops down to a cirtain value then it will stop working (like a dead battery). i dont know if the battery in nokia phones have a sensor in them or not but dont let it die all the way down or else it might ruin the battery! also this might be only for rc car batteries but if you over charge them they will catch fire!
 
Romeo has it. Top up lithium ion and lithium polymer batteries. Drain NiCd and NiMH batteries. I've got a 4-year-old cordless phone NiCd battery that still works great and a 4-year-old LiIon battery in a Nokia 6590i that also works great because of following this procedure.
 
I don't think we have to worry about fires bursting out of our cell phones because we can't get to a charger in time. I've had my N73 drop dead a couple times after some very heavy usage and I've never experienced lesser battery life, much less a fire emergency. And yes! I DO pump my gas while on a phone call because it doesn't matter.
 
are you sure you didnt have speaker phone on?!

but yah i do understand, why the heck would people be lookin? i give them a dirty face, just to see what they would do, its funny! it was proven by the mythbusters that a cell phone can not set the gas on fire!

back on topic: that was just from a rc pov cuse we charge a 4000mha lipo battery in like 30 min.
 
Unlike nickel and lead-based batteries, a new lithium-ion pack does not need cycling through charging and discharging. Priming will make little difference because the maximum capacity of lithium-ion is available right from the beginning. Neither does a full discharge improve the capacity of a faded pack. However, a full discharge/charge will reset the digital circuit of a 'smart' battery to improve the state-of-charge estimation

So I guess there is a benefit to at least discharging it and recharging it every once in a while....slightly better life...

..and there is a gas station near one of my offices that has a sign that states no cell use while pumping gas....and I never understood why it was posted. What's the myth about pumping gas and using your cell? Is it battery related?

........and I could search JB but considering there is an open discussion I figured I would ask
