Anker Battery ok to charge overnight?

[arthaz28]

I notice the "tips" to use it to charge it to 95% MAX, and use it to no less than 5%. Are these claims true? I have no problems of re-charging it before the 5% mark, but to constantly keeping an eye on the phone while charging it can be tedious and annoying.

Anybody can shed some light my way regarding this subject?

Thank you!

Well, your anker lipo would feel better (and any other lithium polymer battery for that sake) if you would not do full cycle every time. Full cycle means you goes from full to empty charge/discharge. (95 down to 5% counts almost as a full cycle)

Say chemistry in lipo can make 200 full cycles before 20% capacity lost or 500 half cycles (like from 100 to 50% and then recharge to 100%). See the difference, longevity will be bit better with half-cycles.

If you store lipo for prolonged period of time (like month) then don't charge it to 100% but to 50%.

And don't keep your phone in high temp zones (like in a sun in the car) this will kill lipo in no time.

Other then that just enjoy your anker. It's cheap enough to replace it in 500 half-cycles (which might be translated to couple years)

Thanks for the response! From the way you describe it, it sounds very familiar with how my lipo batteries for my rc cars work.

I usually charge my phone at 30% mark to fully charge. So, given that, it'd be ok for me to charge it overnight (to 100% then trickle charge until morning), and let it discharge to 30 - 40% then recharge.

Phone will stop charging lipo when it reaches 4.2V so there is no problem to over-charge it... keep it on a charger overnight.

I do one full cycle about once in month but this is for different reason.

Usually, I can go from 100% at morning to 40% at evening in two days. Then recharge it overnight. I think my Anker 2200mAh will outlast my SGSII.
