Re: Proper Mugen 3K mAH initial charging?

Assuming the phones are kept cool, I've never been able to cause a fully charged battery to begin discharging while hooked up to USB, even during long 2xx kB/sec transfers.

I never recall reading anything in the manual for my Mogul or Touch Pro suggesting a 12 hour initial charge, and I made it a point to read the owner's manual for both phones. The new battery came 'bare', nothing but a large back piece and the new battery, with small foam pieces to keep it from sliding around. These were wrapped in plastic and tape. Kinda left on my own to figure out the best practice there..

I did read about Li-Ion batteries online quite a bit, and they all make reference to keeping the battery as fully charged as possible, while also keeping it as cool as possible. Several sites also caution against fully draining a Li-Ion battery, warning that if they are drained too low, they will be unable to safely take a charge and an internal safety circuit will sever the link to the cells to prevent possible property damage. (ie, fire, boom, etc..)

I'd never make fun of you or call you stupid for your battery charging beliefs - You've shown that you are a smart guy in several threads.

I'll be tracking the runtime of this battery as best I can, and if it drops to less than ~80% of its rated capacity, I'll be notifying the manufacturer and getting a replacement. By my calculations, a 3,000 mAH battery should run for 9.51 hours if a 1,340 mAH battery runs for 4.25 hours. As far as I can determine, that 80% cutoff is anything less than about 7.60 hours.
well ur phone does the protecting for you... our stock cords give 1A of output... i pretty sure usb charging only does half that(feel free to correct me).. but there is a difference somewhere in the output of power... usb charging has always been considered the slower and less reliable way to charge by most... do u use the "fastcharge" found on nuerom.com or something? this supposedly changes a default "block" in the phone thus allows for 1A ouput to come through your usb from your comp...

its on the top of page 4 in the "basics guide" included with your tp...and in asurion replacement packages....see pics

and i didnt mean anyone specifically making fun of my practice, it was just a phrase of generalization really...

but yeah keep people posted on if it was worth it to upgrade the battery... maybe just repost in here though, instead of making new threads everytime
