How long are 14500 batteries supposed to last?

[sandybeach]

Question - I am a fairly new mod user. My mod uses two 14500 batteries. I have had it for two months. I use three sets of batteries and alternate them. I've noticed that the battery charge is lasting about half as long as it did when they were new.

How often am I supposed to replace the batteries?

Thanks!
Sandy

Oh, by the way, I use the AW IMR 14500 in a box mod. It used to last all day between charges, now it's about 4 hours. They seem to charge faster, too now. I have a good charger (Xtar) and I don't leave them on the charger after they are done.

It kind of depends on the battery and how much you vape but, I get a lot longer than that from AW IMRs. How long do they last you on a charge when new?

I vape at about 4 volts with a 1.25 dual coil cartomizer.

That's pretty stout. It comes to 3.2 amps. I use 14500s in a Reo mini with a 1.8 ohm atomizer that's 2.05 amps. I can't place it but, I seem to remember that I read somewhere that pulling more that 3 amps on those batts would shorten the life.

I'm curious, what mod are you using?

A little Varicool VV box mod from SmokTek. Maybe it's because I use the dual coil cartos. Oh, I also use the GoGo 3.5 ml dual coil cartos, too. I think they are around 1.5 - 2.0.

You don't see a lot of VV mods that take 14500s that's why I asked. I think you're probably pushing the amps a bit. Actually, it sounds like you're pushing the mod close to it's cut off point too. Have you considered going to something with higher resistance?

Like what?

sometimes i find that the charger light turns green before the batts are fully charged also, sounds like this is your issue due to you say they charge faster now.

I have a screw-in voltage tester that screws in where the cartomizer would. Can I test them with that?

That meter won't really give you straight battery voltage because it's reading both batteries through the regulator in your mod. If you have a multimeter you can test the batteries themselves.

I use a 2x14500 box mod as well (different than yours) and I get around around 6-8 hours between charges. I vape 1.5 ohm dual coil carto's at just over 5 volts. Vape time depends on how heavy I vape.

Each battery should be coming out of the charger around 4.2 volts.

Yeah, you should be usiing a multimeter. They can be bought very inexpensively.

im unsure if they are "spot on" i have a VV mod and if i hit my power button a few times it tells me my voltage, never used the testers before so i am unable to answer that, sorry, its worth a shot tho, i know 3.7 volt batts when full are about 4.1v fully charged, so yours fully charged should be alittle higher then 3v

Hmmmm, I think I'm getting around 4 hours. The batteries are 2 - 3 months old. Maybe I should leave them on the charger after it turns green? Or just replace them.
