It has USB charging out of the bottom. I don't think you could piggy back either the Apple charger into the Dynex or the other way around hence my suggestion to not even use the Dynex for iOS charging. The Dynex cable itself will not induce the 8 hr charge limit correct? I agree the cable should work - thinking it was some sort of switching cable defies all logic.
No it's not. If the charger overcharges them, they could explode, so most chargers know when to stop. The real reason that people say not to leave them fully charged for long periods of time is that they can explode if accidently shorted out. It's the needed circuitry to prevent these things from happening that's forgiving.
Li-poly cells are more forgiving, but with most of the benefits of Li-ion cells. Funny, Apple says otherwise: [apple. I've not seen the iPod battery pack, but I suspect it's a 2 cell Li-poly. In that case, the unit should shut off long before either cell could ever be reverse charged.
But it's definately a concern when you have more than 3 or so cells, and you have something that doesn't automatically sh. LiIon batteries have a maximum lifespan, aroudn cycles. The deeper the discharge, the more "life" you use from the battery.
Like lead-acid batteries, they are NOT forgiving of complete discharge and ch. I think the consensus is Li Ion and NiMH batteries are better kept close to full charge, and NiCads should be drained fully before recharging.

There doesn't seem to be any official word from Apple on their website, so I was hoping the smart people here could clear it up for me. This discussion has been archived.

Apple Ipods use Lithium Ion batteries, like a lot of portable products. So, don't leave it on the charger. The battery will last longer. Share twitter facebook. Re:Discharge Batteries Score: 2. Re:Discharge Batteries Score: 2 , Informative. That's a good point! Re:Discharge Batteries Score: 4 , Interesting. Kind of like how most modern consumer electonics devices have smart chargers that stop charging the battery when it's full? Parent Share twitter facebook.
The apple dock stops charging when the ipod is full. Re:Discharge Batteries Score: 1. One thing to consider is, if you leave it on the charger while listening to music, it will not be runing off of the power source, but rather the battery, which is constantly being charged, so it may reduce the life.
Re:Discharge Batteries Score: 5 , Interesting. Depending on how the charging system works, that may or may not be relevant. Actually, if you leave it connected long enough without accessing it, the hard disk in the iPod will spin down. I actually used it as a scratch disk for downloading about 3GB the other d. Disk mode Score: 2. Re:Disk mode Score: 1.
You do? I don't. Apple knows the same thing that the rest of the computer industry does as well as most car manufacturers You just have to balance how long the life of the product is so that it is -just- long enough not to make the product seem "cheap". I was in 2 different compu-shops this season buying gifts.
In one shop a lady was yelling at the salesman because she could not g. Re:Disk mode Score: 2. Apple quite purposely made a disposable product with a life just long enough to keep people barely happy enough to buy again.
As with computers, I think such products should have a government mandated company paid-for disposal program. A simple way to replace the battery would fix the problem, but would lose Apple money. Thanks, it is not a subject I have any need to take the time for since I own a different brand portable, but I will now correct the sales people when they mispeak if I hear it again.
One of my more insipid vices : While invalidating alot of my angst : you haven't changed the fact that the word is simply not out there among the masses. I'll retract my original statement with glee, I'm always happy to see good ecological practices. However, Apple needs to edumuhcate the sales forces at their various retail.
Most quick chargers shut off or trickle charge the battery and are not harmful to the battery. I have many NiCads and LiIon batteries that have well over charging cycles and some 10 years old that are almost as good as the day I bought them. If you care for your batteries they will last a very long time and if you don't, they won't.
It is as simple as that. The article mentioned tells the right way to do it In many ways, lithium-ion is superior to nickel and lead-based chemistries and the applications for lithium-ion batteries are growing as a result.
New metal and chemical combinations are being tried every six months to. Ni-Cd: Drain them out completely and then recharge them until full. Ni-Mh: I think it's same as above, but the memory effect isn't as bad as it is for Ni-Cd. I might be wrong thought. Not good advice Score: 4 , Informative. Don't drain your batteries. Cells in a pack will discharge at different rates. When one dies and is driven in reverse by the other cells, it will be permanently killed.
Memory effect is real, but you will not ever notice it, unless you do dozens of discharge cycles that are all the same length, to an accuracy of a few seconds.
This isn't going to happen in normal use. Basically, use your iPod. Charge it when you like. Don't run it all the way down.

Re:batteries Score: 5 , Informative. Re:batteries Score: 2. Sadly, i don't know what properties Li-Ion Polymer batteries have verses standard Li-Ion cells, aside from the fact that Li-Ion Polymer is more of a flexible sheet rather then a AA shaped cell. Re:batteries Score: 3 , Informative. Li-poly batteries are very like Li-ion cells, but they're less likely to explode if overcharged. Beyond that, and the possible shape differences, I don't think there's much of a difference.
The link you gave explained it pretty well Not the 3rd-gen iPods. They use regular li-ion batteries. Re:batteries Score: 1. The memory effect present in Ni-Cd batteries is caused by crystals of Cadmium forming on either the anode or cathode I don't remember which. The memory effect is not supposed to happen in NiMH batteries as there is no Cadmium in them.
The high capacity NiMH batteries I have tell me to keep them topped off as much as possible to prolong their useful life. Li-Ion batteries do not have a memory effect that I know of, so there shouldn't be a problem topping them off, but I haven't heard if this is good or bad.
Here is a great article [ussc. Mostly, but never drain ANY cell completely! This can cause a dead cell within the battery and it will need to be replaced or if you know the "trick" it might be revived.
What about a lithium polymer battery? Score: 2. I have experienced problems with my iPod when I let it run down completely, it drops into 'zombie' mode and cannot be woken without unplugging the battery. This is a pain in the arse when I'm going to be away from my computer for a long time. The iPod is one of the first of the first generation and can now only hold charge for around an hour.
What we really want is sony to release the batteries to the general public UK so we can refit them cheaply ourselves. Re:keep it topped up Score: 2. Re:keep it topped up Score: 1. True, but the batteries may well be supplied by Sony. To start the conversation again, simply ask a new question. Can the battery be overcharged on the ipod touch? Or if you leave it plugged in past the needed charging time, will that do anything to the ability to hold a charge?
It would seem reasonable to use the electrica power whenever possible. I have an ipod touch 4th gen. Posted on Jan 28, PM. Jan 28, PM in response to fiddlestix20 In response to fiddlestix The battery cannot be overcharged The devices then just run on the line power if used while plugged in. Jan 28, PM. Page content loaded. In regards to charging then, is it better to wait until it is down to charge, or charge it more frequently to keep the charge up? I know Apple says the battery is good for charges cyckes before it starts to operate at less than optimum.
It makes no difference. Apple does recommend that your almost fully discharge followed by a full charge monthly.
