Need an Electronics Geru for resistance info

[EddieS'04]

I have a couple of, 3.6vdc/600ma and 1000ma lithium-ion batteries. I want to try and discharge them more than their service will do. Hoping they will recharge more fully.



What resistor range in ohms and watts, would I need. Im sure it will take a high wattage as so not to burn the resistor.

I also realize that lithium-ion batteries dont have the same memory problems that ni-cads do. I have read they can have some though. That is why it is recomended to not always use your laptop on power assist. Also to let the laptop battery run down fully sometimes, helps longevity.



Battey info; these are for a vaping system. I havent smoked real tobbacco since march of '15. Vaping is the only thing in years of trying to quit that got me off tobbacco. Also I have been slowing down on that. I just hope not to buy more batteries.



I plan to do this outside as to not have a fire..LOL

Thanks

What I know about Ohm's law, a 10-watt resistor would work fine. As far as ohms, it is just a matter of how fast you want to drain the batteries. It would probably be safest to use a higher ohm resistor to drain them slower to avoid too much heat. Sorry, I don't remember the formula for calculating what ohms you need.



Someone much smarter will jump in soon and give you better information.
