Charger

Anyone know, I want to grab a backup charger asap. Some seem to say that the voltage is ok to vary within 1v... also.. the average USB port gives 5V worth of power.. meaning that all USB phones can use 5V to charge. That sound reasonable?

Last thought, theres no battery memory or capacity issues with Li-Ions or Poly's, or vert very little.

The problem is, Phones an other equipment, need to run a few full charge to death cycles to establish a complete battery algorythym for displaying capacity, from its understanding of voltages.

Its a deep case but, full charge to death at least once a month to keep battery meter in check.
(Don't ever keep restarting a unit once it shuts off to a low power situation, it is possible to exceed low side cut off, an the battery will need to be jumped, or trashed depending on case by case scenario.)

Lol

What worries.(Thermal issues are all but behind us, unless they start using Cobalt or manganese, in them again, i cant remember which, but its the bad voodoo, and i think they got that process fixed now)


I think..
Peace

The charger i can't say if its pinned out identical, but if it is, the power will be fine.

Exactly, theres very little memory, there is techincally, but too minute to cause issues.

Do not worry about leaving it plugged in, it will not overcharge or hurt/degrade the battery.

True, the circuitry that controls the charge cycle, rate,draw,thermal,low an hi cut off's all controlled by miniture switches built into each Li-Ion.

Charge input rates, are limited by these values established by the li-Ion manufacturers.

Onl thing you can do now a days to hurt the battery or others is, get it wet(Lithium+Water) big show, but most are hermetically sealled and other way is to drive a sharp object through the battery itself.
(Lg even recommends, to keep sharp objects such as animal teeth from puncturring their battery.)

I used to let the boys at the shop play with my old Li-Ions, most used a 4 foot stick with a nail in the end of it an push it through the battery for smoke an fireworks.

Or just expose it to the atmosphere, lithium will react with the water in the air itself an catch fire.
(an to think, you can carry on 5 indivdual batteries or a couple laptops on a plane, each battery has the potential to burn through the plane itself, only way to put out a lithium fire is to smother it with earth.)

The standard rule of thumb in my charging setup is, smoke or flam, through it through the window, don't even bother opening it, at home this is lol. Li-ions in my R/C hobby don't have safeties...

Wow, o/t huh///
Yeah i like batteries..

Sorry
