Do AW IMR Batteries Keep Taking Longer and Longer to Charge?

[NicLiq]

I cycle charge two AW IMR 18650 batteries and four 14500 batteries on an Ultrafire WF-188 charger.

Each 18650 is on the charger every other day (usually). They used to charge in about 3-4 hours, but now it's taking over 8. I just checked one and it was at 4.13v after 9 hours. I think the charger light turns green when they hit 4.20v.

They are a little over 2 mos. old, so would have about 35+ charges each.

The 14500 are newer, but I am noticing that they are taking longer and longer to charge too.

Is this the nature of those batteries? Does there come a time where they won't fully charge?

I'm going to go with a charger issue. I have a few AW 18650 IMRs, all are over 2 months old and I charge at least one per day, and they still charge in the same amount of time as always, about 45-50 minutes(using a PILA charger)

Make sure you have the selector on the 188 switched to 650 mA. Other than that sounds like a charger issue.

were you running them until they were fully drained or taking them out before they discharged below 3.5v?

 

[NicLiq]

I thought it might be the charger too, but two of the newer 14500s charge normally, the ones that are about 6 weeks old take longer (I have electrical tape around them so know which are which).

The charger has always been set on 650 mA (and 3.7v). I guess I should just buy a PILA, but I still need to figure out what I'm doing to these batteries.

i think provape still has a sale on the pila. it won't show till you add it to your cart

 

[NicLiq]

I've never let any of them drop as low as 3.5v. I thought I was close once, but it was still 3.6-something.

 

[tybin]

well that is odd then

Thanks, I just bought it - was $45 and it took another $5 off in my cart. I wanted one anyway, I'll call it a birthday present

I hope that's the issue, but I just don't think it is. Do we have anyone here who's been using AW IMRs long enough to describe what happens when they're shot?

 

[tybin]

are you a july baby too?

 

[NicLiq]

are you a july baby too?

Yep - usually the hottest day of the year (tomorrow). Happy Birthday to you too!

 

[tybin]

happy birthday to you!!!! mine's not till next week. ok sorry for getting off track

 

[NicLiq]

Off track is better because I just put my last charged battery in while watching red lights blink over and over. If I have to resort to my Riva, I'm going to cry.

I sure hope it's the charger - if all of you thought it was, it has to be. Thanks to everyone!

I've had 2 pair of imr 14500 in rotation since December and and 1 pair of IMR 18350 for about 2 months. I charge the a pair of 14500s every 2 days or so and the 18350s every 3 days or so I've notice no difference in charging times or vape times in between charges.

This makes me more confident that it's probably the charger, thanks!

 

[NicLiq]

It was my charger, the right side was only charging intermittently, and when I had two batteries on it, the left side started acting up. If I had one battery only on the left side, then it worked.

I received the Pila today and it's awesome! It's like a REO for batteries.

Thanks to everyone for their help and extra thanks for talking me into finally buying a Pila
