Test / Review: Panasonic NCR18650B 3400mAh (Green)

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. :slight_smile:

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, etc…
and unprotected didn’t.

So… If I’m 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

I’m gonna used it for some kind ultrafire XML-T6 flashlight is it OK ? After an hour using full brightness it’s very hot.

Thanks.

In a good, reputable charger, the unprotected Panasonic NCR18650B cells shown in the 1st post will also stop at or around 4.2v’s. 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 don’t 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 ?

I’m already charged for 7 hours and still charging… 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 ” the Sanyo NCR18650BF is better “: Wholesale Panasonic-Sanyo NCR18650BF – 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 ‘NCR18650B’, they think ‘best 18650 around’. When they think ‘NCR18650BF’, they think ‘WHAT?’. People don’t 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 cells…

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.

from what i read the Sanyo NCR18650BF are better then the Panasonic NCR18650B
then why are the Pana B more then the Sanyo BF

4 pcs protected NCR18650B (free international shipping and tracking number included) = 26US$ from Banggood (with mentioned discount code)
vs
4 pcs protected NCR18650BF (Registered Airmail via Sweden Post $2.05+) = 36.16US$ from Fasttech (with BLF discount code)

or
4 pcs unprotected NCR18650B (free international shipping and tracking number included) = 24US$ from Banggood (with mentioned discount code)
vs
4 pcs unprotected NCR18650BF (Registered Airmail via Sweden Post $2.08+) = 29.30US$ from Fasttech (with BLF discount code)

So, how about you provide some proof to your claims (like a link to a store where we could buy NCR18650BF for less than 6$(unprotected)/6.5$ (protected) with included free international shipping and tracking) or stop spamming the forum

My concern would be the packaging.

I only bought cells once from GB. They seemed like genuine Samsung cells, but they came as 4 naked cells, packaged loose in one shared little ziplock bag.
This little bag was loose inside the regular padded shipping envelope, without any other means of protection.
One cell arrived dented. It took a hit from either the other items in the order, or the other cells.

For the safety of the mail and shipping systems, and myself, I will not order cells from GB again.
FastTech ships in bubble-wrapped 18650 plastic storage boxes and I never had an issue with these.
ME takes special precautions when shipping, never an issue there either.

here you are http://www.aliexpress.com/item/10pcs-lot-3-6V-3400mAh-Original-for-sanyo-NCR18650BF-rechargeable-Battery-18650-3400-mah-batteries/32380122609.html

BTW Ali E. has a good protection plan and if these prove to be fakes you will get your money back
so

i also have 2 Liitokala lii-500 on the way that measure the real mAh rating its the 1st thing i will do when they come BTW lii 500 is LE$$ THEN $24

BTW while i am newish to 18650 (only about 3 years) i am a long time purchasing agent and i find low prices
one possible reason is that with the newly released NCR18650GA @ 3500mAh the now old are being dumped in favor of the new

BTW there are ALWAYS DEALS (past now over deal sadly i only ordered 12pcs)
Panasonic 3.6 Volt 18650 Battery 3400 mAh-4pc for $16.99
