Who started this Lithion Ion battery conditioning.

---

There is no “break-in” or “conditioning” required for the Li-ion batteries. They do not need the old “fully discharge – fully charge” routine for the initial three charges as was recommended on older battery technologies. For a number of years now, the advice has been to fully drain a new rechargeble battery at least three times in a row, then do so at least once a month from then on in order to ‘condition’ it. This is designed to prevent ‘memory’ effects and to prolong the life and capacity of the rechargeable battery.

Unfortunately, it appears that this advice is not only incorrect but could be causing battery damage in that it’s reducing the shelf-life of your equipment.

Modern Li-ion batteries apparently do not suffer from memory effects. All that matters is how many recharging cycles they support. The more cycles they are put through, the less effective they become at holding a charge down the line. The caveat, however, is that you can accelerate their decline by forcing them to drain deeper and deeper.

According to Battery University, the depth-of-discharge on a Li-ion device will determine its ultimate cycle count. What this means in practice is that you should recharge your battery frequently and let it drain as little as possible in between recharges. Partial discharges are better.

As expected, high temperatures are also disastrous to the lifespan of Li-ion batteries. Interestingly, high-voltage charging has a similar effect. Higher voltages will charge the battery faster but damage it. The article suggests that user-regulated voltages for laptop batteries might be a useful way to allow the consumer to decide which is more important to them in their daily useage – faster recharge or longer life.

Always store a Li-ion battery full charged. Not doing so will reduce its lifespan and capacity.

Similarly, it would seem that keeping it connected to a power supply when it is 100% charged is not very wise either.

Thanks for posting this! I was wondering something similar after I got my Sensation. I was looking to improve my battery life and was wondering if the fact that I've let my battery discharge irregularly only a handful of times along with hardly ever leaving it off the USB laptop cable at home had anything to do with it. I'll be sure not to discharge it unnecessarily from now on.

I have to disagree with this to an extent, as its preferred to discharge and recharge the first times, as it freshens the cells and calibrates the phone to the battery.

But after this you should recharge it when it's at 30-40%


Also you should not leave a lithium batter fully charged when storing it, but rather have it at 60% and throw it in the refrigerator. This is what i have been doing to all mine batteries, but don't let it freeze though, this will harm the battery!

There's nothing worse than a know-it-all Uni student! If there's a real technician or scientist on the matter I would like to hear their advice.
As I am a mechanical technician I use a variety of battery powered tools all of which are Li-ion, I like to condition all my batteries but for the few that cannot be conditioned due to lack of time those particular batteries are, weaker, last less time and overall die out faster.

Haha, it's not a Uni student, its batter university, a well known webpage

I see, so I suppose it just posted this all on its own?

I believe i can say i trust him

Are you sure? sounds more like Dracula's side kick, haha

This is exactly what I do. Last time I drained a phone down to 0% it killed the battery and wouldn't hold charge like it used to (was fine before I did it). Was on an old LG. Same thing happened to a friends phone too. From then on I try and tell everyone to never do it as well.

While I'm sure you have your sources, I have to disagree. When I got my vibrant, I didn't condition it at all, battery life was horrible. I bought a new battery (the same one), conditioned it, and it was 10000x better.

But I do agree that batteries have become much greater than they used to be about this.

Batteries are always a fun topic
