I got 2 pairs from FT that look exactly like those, and they measure right at 70mm with my cheapie caliper, so Iād say the spec is pretty close.

Just measured mine - 69.59mm
i guess its not a good thing to use this battery on a charger that only charges up to 4.2 v ? like the nitecore i4 ?
?
You have to use it on a 4.2 volt charger or risk problems.
The battery is full charged with 4,2V.
If you have other batteries like the Samsung ICR 18650 30A which is full charged with 4,35V - a 4,2V charger is not a problem and will not harm the battery. Of course it's not charged 100% full, but you can read in many thread, that a not 100% full charged battery will have a longer lifetime.
sorry i thought fully charged is somewhere between 4.2 and 4.35 hence the correction above.
thanks you.
HI,
I would like to ask the difference Panasonic Protected and Unprotected batteries.
In protected batteries it had some kind protection for overcharge, over-discharge, etcā¦
and unprotected didnāt.
Soā¦ If Iām charging the protected batteries, it will stop if the batteries FULL. ( Green Light )
what about the unprotected one ? Is it the same ? My charger output DC = 4.2V
Iām gonna used it for some kind ultrafire XML-T6 flashlight is it OK ? After an hour using full brightness itās very hot.
Thanks.
In a good, reputable charger, the unprotected Panasonic NCR18650B cells shown in the 1st post will also stop at or around 4.2vās. The protection circuit just cuts out when the voltage gets to low in the cell from usage, not necessarily from charging, or overcharging. I have several of these cells, and they are excellent! Better than most other cells. When using them, you just have to be very disciplined and be on the lookout for the 1st significant dip in output on the drop in, and then stop and recharge immediately. Most good, reputable drop ins have a protection circuit built in that will stop the output of the light when voltage is too low.
I donāt think mine is reputable charger. It only said Video/Camera Digital Travel Charger.
Input : 100-240V max 150mA
Output 4.2V
How long usually it takes to full charged it ?
Iām already charged for 7 hours and still chargingā¦ Is it Normal ?
Thanks.
With a fast charger about 4 hours from empty, slower chargers can easily be twice that time, but that does not make them bad chargers.
hey smoke can i ask u something
why does this Panasonic NCR18650B co$t more then the Sanyo NCR18650BF
when ā the Sanyo NCR18650BF is better ā: Wholesale Panasonic-Sanyo NCR18650BF ā 18650 Battery | BATTERY BRO
thank you
Sellers will charge whatever they think people will pay. Price never represents which is better, of any product.
Alot probably has to do with ignorance. When people think āNCR18650Bā, they think ābest 18650 aroundā. When they think āNCR18650BFā, they think āWHAT?ā. People donāt know about this battery, and are unlikely to choose it over something that they have been told is the very best for the past few years.
I just bought NCRBs protected for 6$/pice, where can I get NCRBFs cheaper (with free international registered shipping included)?
Link pls!
6$ per piece would be a bargain for those cells!
oops, my mistake, unprotected are 6$/piece, protected are 6.5$/piece
but here you go:
also worth considering this: http://www.gearbest.com/batteries/pp_190732.html
THanks!
Ordered 4 of the protected ones!
The price from GB is very good - if they are real cellsā¦
Same here.
Ordered 4 protected button tops from GB while they were on sale.
Now have to wait how long it takes to be delivered to Singapore
Gearbest is getting a bit of a slating recently, but I do believe the cells with be real. Well I hope so as I have some Samsung cells on the way.
