2600 mah 18650s

[longworthb]

Ok i got my silver bullet on tuesday and fully charged both 18650s. Charger does make a little noise but it works good and fully charges them. The problem im having is they dont seem to last as long as i think they should. Im not a real heavy vaper and there lasting about a day. My riva 750s lasted me about 6 hrs so these in theory should last alot longer then they are. Im wondering if anyone else has the xsl ultra fire 2600mah 18650s and how long they last

I've been using the AW 2900mAh 18650s and I can vape for two days with them. They aren't even fully depleted after that long. I have a couple of Ultrafire batteries that are rated at 1300mAh, but only last about 10 or 11 hours. The AW brand batteries seem to last as long, if not longer, than they're rated so I buy them exclusively now. They're a little more expensive, but I think they're well worth it.

This is what I noticed about UltraFire batteries:

1. Inconsistent quality... 2 out of the 6 batteries that I ordered had their pcb's and button tops slightly askew. Sure a quick roll on my floor solved that problem, but after that the shrink-wrap on the battery seemed a bit loose after that.

2. Overstatement of charge capacity... I have 4 UltraFire 18650's rated at 2500 Mah, tested on my meter at 1900 Mah, tested my AW's and they tested at 2050 Mah while they are only rated for 2000.

3. Chemistry difference... The UltraFire batteries are a LiCo (ICR) type of battery, AW also makes LiCo batteries but the LiMn (IMR) batteries have a much lower internal resistance (C Rating.) To fire standard 510 attys you need to have at least a 4c rated battery or a 2amp output, ultrafires only weigh in at a 2.5c rating whereas the LiMn types bottom out along a 4c rating. You are putting a great deal of strain on your batteries and thats why they seem to peter out fairly quickly...

Hope this helps...

I have 1 of that exact battery - and it's my favorite. I easily get 2 days out of it with moderate vaping on LR atties and cartos. In comparison, I used to get almost a day out of my eGo 600mah.

Do yours go completely dead before charging? How long is it taking to charge them? What are the specs of your charger?

ETA: Thanks for your reply, VapoMonkey. I'll be sure to give AW a try next time I'm ready to order a batt.

they take about 7hrs to charge and yes there completely dead when i charge them. the charger is the one they carry at altsmoke AltSmoke.com | Personal Vaporizers | Electronic Cigarette | Ecigs | Battery Charger (10430/10440/14500/16340 /17670/18650) - Chargers - Accessories. i submitted a ticket after i talked to live chat on there site and he also said he has the same batteries and they last about 2 days

I got 3 of those batt's when I bought my Silver Bullet. I can vape them for around 24 hours each before vapor production starts falling off to the point where it's noticeable, but I've gone 2 days before when I forgot to charge. I usually just charge when I go to sleep though. I vape ~3ml/day.

I could be wrong, but it's possible that the batt isn't getting fully charged. I'm not near my charger to get the specs, but a fully dead 18650 takes me 13+ hours to fully charge. Maybe try vaping on it after a full charge for an hour and then replacing it to charge and see how long it takes.

My batt's from 3.7v take around 8 hrs to charge to around 4.15v where they top out on my charger.

As stated above UF batts over rate their mAh. AW or Redilast are the way to go. I have 2600mAh Redilast 18650's myself.

AW2900's also I really really like the way my Redilast 2900's run, just make sure they fit your Mod they are a tad on the big side but they have sick power and are hard hitters I really like these Batts a lot.
