Interesting, so it doesn't really affect battery life. What about the charging time? In piezoelectronics, a voltage is generated, so if it's 3x the voltage, would it take 3x the amount of time to charge?
Obviously there are MANY differences, but I'm curious about one in particular.
In an article I read, the creator used NiMH batteries because of their high charge density, but also because they do not require a charge controller and voltage regulator in the circuitry. Why is this, and is there...
So for a DIY project I'm doing, I want to replace my iPhone battery (about 1810 mAh, 3.7V) with a NiMH battery (300 mAh, 1.2V) but I need help getting past some of the problems (and maybe more).
First of all. I've read that iPhone batteries are non-removable, is this true?
I've also read that I...
Another question-I was reading an article about how the batteries were getting larger in phones (like 1800 mAh to 2200 mAh) so the battery lives were getting longer. Is the relationship between mAh and battery lives shorter? For example if I tried to use a 300 mAh battery in a phone, would it...
I read it here http://www.forbes.com/sites/eliseackerman/2014/12/19/will-rapid-charging-damage-your-iphone-6-or-6-plus/ and it gives the reasoning for it not affecting battery life is that the extra heat generated isn't too high and the C-Rating. The information in this article I found elsewhere...
So what determines this limit? For example, I read an article stating than iPad charger could charge a phone 4x faster since it offered a current of 2.1A compared to a USB charger of 0.5 A (without damaging the battery). What determines the limit at which point fast charging turns into...
I see, thanks gleem and davenn!
I'm still curious though, is the reason you can't put 220VAC into 12VAC because the battery would overheat? And if it didn't overheat, would it charge 220/12 (18.33x) faster?
So I learned that outlets actually provide a lot more voltage than small electronics like phones need but that transformers are used for voltage optimization.
Is the sole reason that this is the case is so that the battery generates less heat and doesn't affect the battery as much? Or is there...
That might work, but I want to be able to put the motor generator inside another machine. Do things like small infrared panels exist to go through objects? Things that would be able to take something like a focused infrared source and use the motor generator to create electrical energy?
Okay now that I have a better picture, want to power a generator from a distance (at least 10-20 ft) automatically. I was thinking maybe two magnets could work, if one could make the other generate mechanical energy. Would this work? If not, is there something else that would?
Okay, I did and it helps a lot. Let me pose my problem this way, is there any way I can make one magnet produce mechanical energy once it is in range of another (perhaps through friction)?
