Long before I was born? I am 42 and your age is ? Hair dryers? I don't think I ever saw a hair dryer with a lithium ion battery in it. Since we are talking hair dryers why do they sell chargers for cars and ones for motor cycle batteries? Why not just buy one and don't say buy one that does both that has selectable settings. Reason being is if you use a car charger which is 10 amps on a 2 amp motorcycle battery you will cook it and if you ise the motorcyle charger on a car battery it will take forever to charge it So now you see why they sell car chargers, motorcycle chargers, and ones with variable charging rates. Please explain that one why their is not one charger for all car and motorcycle batteries. Please don't use the excuse they are lead acid, AGM, etc. Since we are on AGM batteries tell me about those as well. What charger do you use. What voltage does a car alternator put out?
Since you have such expertise answer these questions too. What voltage reading will you get on a 220 volt 3 phase piece of equipment coming in from testing supply to supply? What reading will you get testing one supply to ground? Do you need a neutral wire to use this 220 bolt 3 phase piece of equipment ? What size light bulbs do they use for an L train that ONLY has a 600 volt power source coming in?
Here's a test I did with help of a couple co-workers.
Just like the last forum post here we go again. I used an old iPhone and obtained 2 other ones and put brand new batteries in them. Altered the charger to put out more than 2.1 amps and did 50 charge/discharge cycles on one. Did the same with te other one at 1 amp, and the other at .5 amps
After that let all 3 devices sit for 3 days all at the same settings and the one that was charged at .5 Amps had the best battery capacity and the one with the altered charger was the worst? Please explain that and answer my 3 phase power question.
I will be anxiously awaiting your answers to ALL these questions.
