18650 Charging time

[Method69uk]

Hi all

I received my Vamo V3 a couple of weeks ago from Fasttech. (love it!)  I'd also bought a couple of Torchy 2600Mah 18650 3.7v batteries as I heard they were decent.

How long does it take on average for you guys to charge up similar batteries? The first charge took me about 10 or 12 hours and I'm finding that this hasn't gone down.. they're still taking me 12 hours if not more to fully charge to 4.2v.

I'm currently using a Trustfire TR001 charger as Fasttech didn't have the Nitecore i4 in stock when I ordered my Vamo, but I have one on order now.


I'm sure others have said their batteries charge a lot quicker than 12 hours! Is this a charger issue or a battery issue?

Thanks

Steve

Haven't really timed it, but something more of the order of 4-5 hours for the NCR18650B (which holds a lot more charge)

I suspect your charger is 0.5Amps max. It will take forever with large batteries. If you had a 1 Amp charger then it would be reduced to around 4 or 5 hours.

Would you recommend those batteries barrynorton? I was looking to get another couple as I don't want to be left with no power while I have these long charging times!

I've just looked on the bottom and it says "output 4.2v at 500ma" hmmm.

Sometimes I select 0.5 amps on my charger to charge slower as supposed to be good for the batteries to charge very slowly sometimes. Maybe it is maybe it isn't, but when I do this it takes like you have found...10 to 12 hours. It certainly takes a lot more than twice as long than 1 amp max selected.

What charger have you got Brambles? Looks like I need a 1 amp charger!

Not sure what the Nitecore i4 maximum is.. wish I'd looked into it first..

I'm no battery expert, but I did quite a bit of research before getting the NCR18650B and I've been very impressed. Going to buy a couple more myself (about 20 quid for a pair on Amazon Marketplace from well-established torch resellers).

Method69uk an 18650 should last you 2 days, so have one in vamo just charged, and charge the other one on rotation every 2 days so that you always have a ready-charged battery to swap.

I must be abusing my Vamo something chronic GunJack - I have to swap batteries once a day at least!

Might have something to do with the fact I'm off sick and spending a lot of time at the PC..

At 10W on the VTR I can make it through the day, but not for a whole second day (and that's with 3400mAh)

When sitting at a computer all day with a vamo in you hand you will be amazed how much you actually vape compared to being out and about. Normal working days can sometimes go three days if something good on telly at night ( I do not vape in Living room), on one battery.
If I am working on computer all day and again in evening then 2 sometimes 3 batteries easy.

The problem is it is hard to compare with what others do. One person might vape all day but take small puffs, and another might be the same but take longer puffs so gets half the battery life. Whilst a 3400mAH battery will give more capacity it is not actually that much more in say a vamo or other device cutting off at 3.3 volts.

I did a table recently which tried to show what the popular batteries would deliver v cost from Fasttech.

see allaboute-cigarettes.proboards.com/thread/29243/18650-battery-specs-comparison?page=1&scrollTo=527719 might confuse you more or might make sense.

My i4 takes about 4-5 hours, does not seem to matter if battery fully or partly discharged.
