Nitecore intellicharger i2

[Yorkshireman]

Having just bought some flat top 18350 batteries i noticed on the list of batteries the i2 can charge the 18350's are not on the list,can you or do you charge your 18350's on your i2 or do i have to buy another charger,if so which one please.

the i2 can and does charge them very good charger its all I use the i2 and the i4

Thanks Ronaldo,i thought it strange they are not listed.

If you are ever unsure what size a battery is it is within the model number.. 18350 is 18mm in dia and 35mm in length, likewise for a 18650 and other sizes.. 18mm x 65mm so if a charger takes an 16340 upto a 18650 the 18350's will fit...

good answer but do you know what the final 0 means

it means the battery is round a 5 means square and so on it just means shape

But the numbers dont give you the voltage/amperage!!! seems an omission ???

I never knew that Ronaldo... i thought it was a 0 added because they had nowhere else to go with the number...lol

The voltage is printed elsewhere on the battery .

Just checked my 18650 and the only other info is li-ion (obvious) and MH12210, voltage/amperage isn't marked at all

Maybe someone can check theirs for you... all of mine (or at least i think all of mine) have 3.7v on them .. My efest 18350's all have High drain 10.5A on them too.... another thing people dont realize is.. you are better off charging your batteries at a slower rate, everyone wants them charged ASAP so want the fastest charger out there, continuous fast charging actually shortens the life of the battery, plus after fast charging the peak charge will drop off quicker than if its slow charged.... some will argue that point but the faster you charge a battery the hotter it gets.... heat kills batteries, thats why RC guys who need to charge batteries real quick between races normaly have a PC fan rigged up under their batteries while they are charging... i always buy variable rate chargers over fixed rate.

It's the heat build up that is the important part, I would rather charge my VTC4s at 2 A than at 1 A or less on a charger that overcharges them as I have read this is this worst thing from both longevity and safety point of view.  The VTC4 is rated at a max charge rate of 4 A, so don't try this unless you know the max charge rate and keep well below that rate.  Also a charger that does Constant Current for the first phase of charging then switch to Constant voltage for the saturation phase is important.  And most importantly of all the charger must stop charging when the battery is full, sounds silly but I know of at least one Efest one that doesn't.

After having bought a charger that some influential people highly rate (latest model Efest LUC4) and finding that it was erratic and overcharged a lot I started keeping a spreadsheet on charging VTC4s & Pana CGR18659CHs on my two Xtar SP2s.  I always charge the VTCs @ 2 A and the CGRs @ 1 A and they both are only a bit warm when charging, a lot cooler than the water you would wash your hands with.  There is very little difference between the two in terms of voltage drop 24 hours after being taken off the charger: the VTCs drop 15.2 mV on average (38 samples) & the CGR 12.9 mV (35 samples), but the final voltages are different due to the charge current: 4.202 V for the VTC @ 2 A & 4.186 for the CGR @ 1 A which together with the differences in internal resistances between a 30 A and 10 A battery account for the 2.5 mV difference.

This is just my opinion & I am not a battery expert YMMV.

yes it goes 18 width 65 length 0 round so that's a 18650

yes it goes 18 width 50 length 0 round so that's a 18500

yes it goes 18 width 35 length 0 round so that's a 18350

ect ect ect
