Charging AW IMR 18650 3.7v on Ultrafire WF-188 -- Quick Question

[jordan85]

I just received a few AW IMR 18650's and an Ultrafire WF-188

Settings on 3.7v and 300mah

When the batteries are charging, the LED indicator is red, but flashes green every few seconds. This happens on both ports, with both batteries. Is this normal, or am I in currently in the process of ruining my batts ?

That's how mine charge. It'll go solid green when the charge is complete.

remember those batts come almost fully charged..i have the same charger and batts..it will go solid green when done.

Yes that's normal, might want to turn the charging rate up to 650ma for the next charge though. Charging a 18650 at 300ma is going to take quite a while. The light will turn green and stay green when it's done.

Is it bad news to keep those AW IMR batteries on the charger for any length of time after the light turns green? Don't want to burn the house down... ya know.

If the charger is functioning properly, cuts off at the correct time and doesn't trickle charge there is no issue with leaving it in the charger BUT I wouldn't advise nor recommend it. Anything can happen with electronics and in the event it does you want to be there to take care of it asap.

I've had the WF-188 and it shorted out on me (sparked and went dead from static electricity discharged when I grabbed a battery to take out of it). I didn't much care for the spring loading design of it to begin with. I've also had 3 WF-139's and I gave one away because I found it more reliable and easier to get the batteries in and out. I like the 139 too because the second one right now is in my car and has a plug-in for DC (cigarette lighter) that I can use to charge batteries when I'm on the go. Just my thoughts

In regards to the green light flashing as it charges (but staying mostly red), mine does that too and it's normal. Once the lights turn green it wont charge the batteries any more but I still try not to keep batteries on the charger after they are charged.

Just keep in mind this is UltraFire you are talking about. Don't care how pretty the new ones look. They can and have gone into meltdown. The unattended/over night charging concerns me much more that any in-mod battery issues.
