i just want to know how does a cell phone charger works. i know that it uses a transformer and diodes for rectification. my actual doubt is that i have read in a news paper that there would be 30% losses when the charger is given supply and no mobile is connected. am surprised how there can be so much loss

I have several dead battery packs for my 18v power tools. Planning to rebuild them and figuring I might as well upgrade their run time while I'm at it. The original battery packs are 1600mah but I can get 2500mah battery cells that are the same size for about the same price. 1) Will I still be able to charge the higher capacity batteries with the charger that came with the lower capacity ones? 2) Will it charge them to their full 2500mah capacity? 3) Will it be able to detect when they are fully charged? 4) Will it give a false positive and think they are fully charged as soon as they reach the 1600mah of the original battery packs?

All the DIY solar chargers seem to use a feel test or a multi meter to test if batteries are charged. Is there a curcuit utilizing an LED like those on manufactured chargers, that will let me know when my batteries are charged, and possibly put them in float mode or turn the unit off?

I have 2 cellphone battery brick chargers. I took one apart and found it to have 6, 18650 LiPo batteries connected in parallel to a circuit board to charge it. I have a project that requires 12 V and I would like to use these in some fashion. I was thinking put the two parallel battery bricks in series to get 7.4 V and step up with a DC to DC converter. Which one would be appropriate? To charge the LiPo's I was thinking of parallel connecting the two circuit boards from the 2 cellphone battery chargers to a single wire connecting to a 5V cellphone wall usb charger. The usb charger supplies 5V at max 2.4A. Any help would be appreciated!

I have three Black and Decker, 18volt battery chargers, for the FireStorm series tools. One is an orange dual charger. One is the single black charger that came with the drill. And one is the Radio charger. The radio charger AC adapter case melted and no longer works. The single and double chargers both seem to kill batteries, and do not charge. I have voltage coming from the chargers, but I don't remember how much. Does anyone know what the voltage should be on the charger? More importantly, how do I repair the charger to output the correct voltage/current?

Do you think there is a great alternative to the current solar charger? Today, there are many DIY Solar Chargers that are alternatives to the current commercial products. Do you think there is a better design for a solar charger that is not run by an arduino?

I now have 2 Toshiba laptops, a Portege M300 and a Portege M600. My M600 is secondhand, and didn't come with a charger, however i discovered that the charger port is smaller than the charger port on the M300. Will i have to buy a new charger or is there anything i can do? new Toshiba chargers are, I believe, AUD$96.

Hello I want to charge my sony ericsson w580i with my iphone charger. My SE charger is rated for charging at the current 4,9V but my iphone charger outputs 5,25V. Is it harmful for the battery in my SE mobile to have a 0,26V current extra? Or can i put in a resistor between to lower the current from 5,25 to 4,9.
