I've just got a new battery for my mobile, it contained some charge, and the advice I was given was,
use it flatten it, and then charge it.
Curiously I was discussing this someone else, and they said they were told to
charge it straight away, when they bought a new one, even though it also contained some charge.

I know years ago, when the NiCads were first in fashion, that was always the advice,
don't part charge it as it will have a "memory" and subsequent charges will never be "full" charges.

I just wondered if that held true today?
A poll is added for your consideration ;)
 
I have considered all your carefully composed answers Chris and have arrived at the conclusion that I don`t care, nor do I care about JR.

Saying that, I bet some scientific type member will know the definitive answer.........:p
 
Lithium cells won't remember who JR was so you can.... er.... What was the question?
 
I was under the impression that full discharge of lithium ion batteries reduced their life. And that topping up was better for it. Also better to store lithium ion batteries with a full charge. Well that was the impression I had.

He makes Oil, I guess there must be some connection :D

Thank you for taking the time to review all the options Ade,
I consider your's to be the best answer so far :thumbs:
:D

Thats what I like about TP, someone with either know the answer or Google it for you :D

I hope not, one should only buy OEM batteries anyway.......;)

OEM?
Off Ebay Members??

Seriously, that's one I've never heard before interesting...
 
Ive been told that you only need to charge to 80% then once a month a full discharge and full charge, thats how i charge my Moto G battery in the phone and i get 4 days usage from it regularly and 9 plus hours from my Samsung Series 9 laptop

There are more variations "appearing" than I had thought of, interesting :)
 
do not let it run flat ,keep it trickle charged when not in use ,the biggest killer of batteries of ANY type is cold weather so keep it warm ,but do not use a willy as a warmer especially if the phone is on vibrate :wave:

That was not the kind of "leakage" I was thinking of.
 
I was told to completely run them down before every tenth recharge. That guy is a complete a hole so I ignored him. Doesn't seem to have done any harm. Who counts battery charging cycles?

Waits for brash to drop by and use the "W" word :D

I certainly don't, the out going battery lasted about 20 months changing at random times,
even leaving it plugged in on full charge in the car and the like.
But as it was bearly lasting 12 hours on a charge I thought I'd treat myself to a new one :D

Damn! there goes my last pleasure in life :(
 
You should never run a lithium battery flat it can damage it and will shorten the life. Regular top up charges are best but I suppose with the price of non original batteries as low as it is it's not so important to treat them well.

Cheers Hugh.
As above that one lasted about 20 months being used and abused,
run flat a few times, charged when not flat,
left plugged in over night and more.
I suppose a tenner wasn't a bad price for a replacement anyway :)
 
Not sure that most devices will actually completely flatten a LiIon battery. I know that My D700 simply won't turn on when it gets to a certain level of discharge and the charger reports that the battery is 20% charged. Similarly my phone just switches itself off at a certain point - or goes into battery saving mode (I tend to charge it every other night so it rarely gets to that point!)
 
Lithium polymer cells will burst into flames if they discharge too far, and most devices have a limiter built in to prevent that. For best battery life you should routinely discharge as far as possible (less than 10%) then recharge to the top. Top up charges are OK if needed, but not ideal.

Actually I'd noticed mine flashes a warning at 14% I stick it on charge at that, sometimes I miss the "warning" and find it off.
I wasn't sure if it drained beyond that TBH :)

That seems a bit of a dramatic way to get you to buy another!

Thanks I did wonder :D
 
My Samsung moby tells me when there is only 30% charge left and suggests I might want to recharge it. My Samsung tablet does the same.
 
Use it how you want to and just buy another in a years time unlike the apple boys most phones can receive a new battery in a jiffy
 
I used to do safety testing on Li-ion batteries - at one time they had to be run flat to conserve battery life but not any more - technology has moved on.

*they will not burst into flames if you allow them to run flat - dear me, as if! *only applies to OEM ones

always buy OEM batteries as the ones made cheaply in China (usually) can be poorly made and can have safety devices missing and, therefore, can burst into flames for ANY reason. Whenever you hear about batteries exploding they will be cheap ones bought off t'internet.

never leave your battery charging near heat (ie on a radiator), never leave a battery near heat anyway (in a hot car). Try not to drop a battery or get it wet. When I say battery I mean whether it is inside the device or not. It is not a good idea to carry a battery in your trouser pocket (in case it explodes, not because your trouser pocket will cause it to explode lol).

Remember when you did science at school and they had this stuff that they kept in oil as it was extremely volatile in air or water? Remember when teacher dumped a tiny amount in water and it fizzed about then exploded? A pink flame was potassium, yellow was sodium and lithium was red. so, yes, Lithium-ion batteries and water don't mix.

By EU law Li-ion batteries must have at least 2 levels of safety built in to stop things like over-voltage. under-voltage, over-temperature etc. So if your battery gets too hot while charging it will stop charging. But if the battery is on a radiator the temperature will continue to rise and the battery will explode anyway. Please follow my advice because I have seen a small phone battery explode and the fire burned through our work bench (3" thick wood) and made a crater in the floor in mere seconds!

ok, lecture over, carry on with what you were doing :)

:ty: Really good advise despite some peoples aversion to paying for OEM (y)
 
one of the reasons we're seeing a lot of those electronic cigarettes exploding whilst charging/sitting in pockets is that as a device they are unregulated - classed as neither tobacco or medicine (as yet) - so they're probably being tested to a standard that doesn't completely cover their use, but mostly they're made in China, and the Chinese manufacturers look at costs rather than safety. They think nothing of missing out important safety devices to save money in manufacture. It is acceptable in China to pay for safety certificates rather than pass the requirements to be awarded them. Things are improving but very slowly. We once had to help a client who was being sued by trading standards because his (mechanical) device caught fire. Turned out the motor he was using had passed all the safety testing etc at the design stage, but during manufacture the Chinese supplier had two motor options and he went for the cheaper option (which was supposed to be an identical motor), but they'd taken out the thermal cut-out switch to make it cheaper. oops!

Makes mental note to try and knowing avoid buying batteries etc from China ;)
 
Buy from reputable UK based suppliers and you should be OK. Avoid E-Bay and AMP.

Not all OEM batteries are 100% safe - I had my first DSLR battery recalled and replaced by Nikon (IIRC the batteries were sourced from Sony.)
