Rubbish. Lithium cells can be dropped to 2.6/2.7V per cell as a limit. If you try and discharge it futher and you'll never get it to take a charge again.

In fact that advice is downright dangerous. Attempting to fully discharge a Lithium cell can cause it to rapidly heat up and create a build up of hydrogen in the cell, the cell can puff up, in this state a spark can ignite the gas and the lithium metal react with any water and burn fiercely. Remember the laptop batteries that caused fires a few years ago that was through over discharging and shorting.


Phones cut off at the 2.8/2.9 level and say the battery flat, and they will be fine as long as you charge it soon. Flatten a lithium battery leave it a month or so to self discharge a bit lower, and then try to charge it and you may find the cell is deal.

If only basic reading skills were an entry requirement to this site. Please quote the section where I advised anyone to completely discharge their battery...you can't because I didn't say that.

What I said was and I quote "Fully discharging a lithium battery is not a good idea"

Please read before you post nonsense, it saves embarrassment for everyone.

Sorry, but I'm quite confused - started reading as I have just got a HTC Desire S, and thought there might be some useful info here...

In simple terms, what is the best advise for keeping a battery in good health/maximising charge?

In the past with mobile phones I have let the battery become nearly empty before charging it. Is this not the right thing to do?

Your post as I quoted was

"Completely discharging and fully recharging a lithium battery can only be done around 500-1000 times before it will fail altogether."

the bolding is mine.

You did advice against deep discharging and then you went on to state you can completely discharge and recharge a lithium battery 500 to 1000 times.

Does the fridge trick apply to lithium batterys as well?

I thought that only ever worked on non rechargables, From experience Lithoum batteries perform better in cooler conditions but badly if too cold, like in winter.

The should only be chilled if they aren't going to be used for prolonged periods of time. It won't bring life back to a dying battery or anything magic like that.

No, its a very bad thing to do. Have a read through the thread. See my earlier posts about charging sparingly and often.

Thanks. I'm afraid I was getting a bit confused with the above posts!

I'll start charging it before it's telling me to from now on then...it kicks into powersaver at 30% so guess that's the time to plug in!
