How long should the first charge be and should I discharge the battery completely before charging after the first few charge?
Actually I'm looking for a 200-500mw 445-473nm laserOnce your Li-ion reaches ~4.1 vdc unless you have a 'smart' or 'intelligent' charger ( the more 'spendy' ones) remove them/it from the charger- NEVER 'store' Li_ions in a charger.
it sounds like you have no meter or even a battery checker- The Li-ions I sell arrived fairly close to fully charged.
Mine are not cheap because they are high quality Li_ions,, Also , at least for now, the current regs BAN the use of USPS for shipping... thus I am forced to either lie to my friends at my local PO ( which I am not comfortable doing) or use Fed Ex which at the very least is around 2-3 $ more. Fed Ex has one rate for any package one pound or less ~$7.50
so buying just a few batteries is going to cost more per battery than if you ordered a pound of them. The only way around these regs it to send Li-ions inside the intended devices- I was told that cell phone batteries cannot be mailed unless they are inside cell phones.
SO I can send you some, if you want, via USPS as long as you buy the lasers too. China battery sellers will still use EMS or HongKong post which becomes USPS once they are here ....but I will not-- its not like the 'batterty' police are going to china to arrest them.BUT.. .what happens in USA if these new regs are ignored is something I do not intend to find out the hard way..
....I am currently preparing to ship 14 16650s ( for Ti-B JLs) to CT and that will cost my buyer ~$ 8.50 for Fed Ex ground.
they weight 1~.5 pounds.
capeche?
