Thought I would post this for all the guys who were like me who decided to get into the 18650's and tried to wade thru the mass of info that is out there.
I had been reading on this forum and doing research for about 2 month. Ihad read all the info on batteries...
I read all the tacked threads and all the reviews on chargers and the dangers of Li Ion batteries and finally took the plunge. I purchased a TK 35 after spending about a month researching it (Great light, very happy) and along with it I got a Cytac dual bay 139 charger along with 2 protected AW 2900Mah batteries. I wanted to stick with a brand that had consistent high reviews and was always the number one battery recommend for folks new to the Li-Ion game. The charger was part of the package. I had reservations about it based on some reviews and may still get a Pila down the road, but for now, I thought I would try it.
So The first thing I do is take a multi meter to the two New batteries and I get a Voltage of 3.93v per battery.
So based on a chart that I downloaded here (Thanks to whomever did it..) it's telling me the batteries have about a 60%charge.
So I ensure the + and - ends are inserted in the charger. They fit with no issues) and plug it in. I then placed the charger into the bottom of a 50cal ammo can I have and set it on my work bench. Two red lights come on.
I started the charge last night at 5:30pm and kept an eye on the charger every 30 mins. at 10:00pm the lights were still red. At 10:30pm I went back down and the lights were green. I then unplugged and removed the cells.
Both cells measured 4.20v. right off the charger. I let them sit overnight. next morning I remeasure and they read 4.18v. I place them in the light and Viola.. works.
I will be going out tonight to play with my new light. I'll update as I run the light and need to recharge the batteries. Overall I feel very confident on the set up I have now and will continue to measure voltage before and after charging.
