Why Lithium

I prefer to imagine cost as a thick goo, and a battery as a giant shallow pan, which you solely fill from one nook, and the voltage is the height of the goo at that corner of the pan. Because the goo could be very thick and sticky, when you’re filling the pan, the corner that you just’re filling will get full first, however if you wait long enough, all of the goo will ultimately even out throughout the pan. And whenever you drain the pan, that nook will drain first, while a lot of the remainder of the pan nonetheless has plenty of goo in it. It’s hard to inform how the battery’s doing without timing all of it the way till the cellphone dies by itself. Since my cellphone doesn’t perceive how I can presumably have this a lot capability (I use 3800mAh batteries as an alternative of the 1500mAh the telephone was designed for), the studying will go all the way down to 1% and still final for another day or more.

This most likely means not utilizing a wall or car charger, however solely charging from a pc’s USB port. USB port commonplace most output is just 500mA, so that will help a lot. I actually don’t understand how a lot votage charge my battery is getting but I prefer to keep away from the 2 extremes of four.2V charging and also beneath 20% the place it puts pressure on it. @vince yeah I agree it be a fantastic science experiment and would assist to reply some unaswered questions from doubters and restrict the debates whether or not charging discharging initially improves the battery capability.

On mine, my my voltage could be about three.7 to three.6v when my phone would say it was dead. That sort of makes sense, as it was designed for a 1500mAh battery, and I’m using 3800mAh batteries now. I cant make sure whether I’m even getting most capacity out of the battery or whether or not it’s solely charging as if it’s a 2100mah battery. I used to design battery chargers, and I like this text. It provides me sufficient to design the charger for this chemistry.

Maybe tightening the cap places an excessive amount of pressure on components contained in the flashlight. I’d think about that the scale of the battery also components in to it, so what’s considered a quick charging fee for a small battery might be a sluggish rate for a bigger capacity battery. Everything else is a tradeoff between optimal longevity and personal comfort.

If I’m using the cellphone for a long time, video, gps, or something that keeps the display on, the voltage will finally read very low. But after I give up using it and await some time, the voltage will come again up by itself, even with out being plugged in. And should you have a look at the table on the prime of this text, you’ll see that the voltage of the battery will reach 4.2v lengthy earlier than the battery is totally charged.

i’ve heard you may be able to recuperate a “dead” lithium cell by charging it with very low mA, like mA until it comes again as much as around 1-1.5 volts. seems to me it is a flashlight downside, not a battery downside.

There’s additionally chips from a number of producers that can do the identical. I suppose that is why so many GPS batteries have died… i used to be charging the battery while using it. I assume one of the best thing you can do, for what you need, is to be sure to at all times cost it slowly.
