I am curious about all the various charger voltages out there for KR808D-1 batteries. I have a set of chargers originally from V2cigs (gen1 charger I am assuming based on reading the forums) that outputs 4.2V@200ma. I ordered some KR808D-1s from HealthCabin that are of the newer "sealed" auto type and the charger they have on their website is 4.5V@150ma (according to the website, I do not actually have this unit). I am assuming this is a gen2 charger, however I have seem other gen2 chargers that are 5V@150ma. Again, based on reading, its a no-no to charge gen1 KR808D-1s on a gen2 charger, but vice versa is fine. I am curious what other charger output values are out there and why such a wide variance.
The batteries currently in my possession are V2cigs 4.2V@250mah and 4.2V@380mah (unregulated). The ones I ordered are 3.7V@280mah (I assume regulated if they are gen2). I am assuming it is ok to use my V2cigs charger on these units. If this is incorrect thinking please let me know.
