Got my ultrafire 188 charger today from superT. Vapn... I pm'd you bout setting for it. I think I got it set okay just wanna be sure.
Day 2 on the vmax and lovin it. Batteries only lasted me about 10 hours yesterday but had plenty of time to settle in with it. Had one glitch where it seemed to power off by itself randomly and then wouldnt come back on for a minute but it hasnt happend again.
Another question. When checking the remaining battery voltage it shows the remaining charge as total between two batteries. Fully charged should be 8.4v? the low point 6.4v?
If Im wrong please correct me. I know I read it before here but its slipped my mind now.
Hey Buff, since their may be a few out there with this charger or one on the way to them, for the sake of putting it in a post for every one to read, just make a mental note of what post # it is for future reference. Ok....here we go. Im going to break this into 2 small parts."Recommended use" ..&.."My use".
1st Recommended Use : Ok...real simple, their are 2 slider switches on the Ultrafire WF-188, One on the R.side that shows : 3.0/3.2 & 3.6/3.7 (volts). On the L.side that shows: 300mA / 650mA (miliAmps).
-- The recommended charging rate for most 3.0/3.2 volt batteries is 300mA. And the "most often" recommended charging rate for a 3.6/3.7 volt batteries is 500-650mA, in this case 650mA.
-- So this being explained when you charge 3.0/3.2v batteries the voltage slider on the R.side should be set to 3.0/3.2 and the charging rate slider switch on the L,side should be set to 300mA.
-- When charging 3.6/3.7v batteries the slider on the R.side should be set accordingly to 3.6/3.7 and the charging rate should be set to 650mA.
Now "My usage" ( this how I use it as a personal prefference if you decide to do any of the following you do at your own choice)
-- All the above is followed to the "T" by me,... with the exeption of 1 small detail and 2 very simple but different situations.
1.If I want/need my 3.7v batteries to charge quickly during the "day" for immediate use I follow the above directions, 3.6/3.7 switch and 650mA charging rate.
2. If I'm going to charge a battery that is fully discharged (to it's safe discharge voltage of 2.5-3.0v) overnight, I keep the 3.6/3.7v switch as is, but take the charge rate to 300mA so it's a slower charge.
Please keep in mind I'm usually in bed by 11pm (est) and up by 4am(est) for my morning workout and getting to work. So 5 hours is as long as their on there. Theirs only 7 batteries I even use and only 3 sizes............ E'fest IMR 18650 2200mAh.... E'fest IMR 18350 800mAh,....E'fest IMR 14650 900mAh,.....AW IMR 18650 2000MaH,....AW IMR 18350 700mAh,.....And PANASONIC CGR 18650CH 2250 mAh, PANASONIC NCR 18650 3100mAh.
FYI: My E'fest AW side by side tests are very close to being complete and double checked. All I can say right now is "so far" Im in total AHH over the output amperage of every single E'fest I tested. For now I'll leave it at that.
I hope this helps Buff, and whoever else may have the same questions....Take care everyone !!!! ......J
Well I tried to keep it short....o'well . lol
