OK to interrupt battery charging until morning???

[RunAway]

Anybody know what to do if youre charging 4 batteries together? If one reaches charged do you take that one out, or leave all 4 in charger till all charged?

Ninjaassasin1983 Tell me mate please, if youre charging 4 batteries together, when one battery reaches fully charged, do you take out that one battery first, or wait till all 4 batteries are charged, then take out all 4 batteries? Thanks.....

I just realised now that if you're only charging two batteries then it goes in port 1 & 3 or 2 & 4, and you don't charge one battery only, no wonder batteries were getting hot before....first time i read the manual, tonight.....

That only applies to AAA or 10440 batteries
See manual section below

1. When charging a single battery in the I4, the charging
current can reach as high as 750mA, which exceeds the
current many Ni-MH/Ni-Cd AAA and 10440 Li-ion batteries
can withstand. For this reason, under no circumstances
should a single AAA or 10440 battery be charged on its
own, as potential overheating, damage or even explosion
may occur.

However I wouldn't even charge a 18350 above 500 mA but anything bigger should be fine.

If you are charging 18350s I would that they go in linked slots eg 1 & 2 which will limit the current to 375mA per cell.
Note: They won't blow up (providing they are good quality proper batteries) but they may get hot which will shorten their lifespan

Thanks BKKKPewsey BTW if i'm charging all 4 batteries together do i take each one battery out as it gets fully charged, or wait for all 4 to be charged then take out all 4? Dont want to overcharge which is why i'm asking, thanks......

Okay I just bought a nitecore intellicharger and was under the impression that I could leave the batteries in over night with no ill effects as each slot is independently controlled and stops when a battery is fully charged.. Was i misled, or do I possibly have a different charger?

I actually do this all the time. (This is in an i2)
I`ll also charge a single 18350 or an 18350 and an 18650 together or whatever combo I need.
If I need one of them I`ll take it out and leave the other one in if it`s not fully charged.

My understanding is it charges to capacity and then stops, or drops into "trickle" mode.
I frequently charge overnight too

Please note I do not necessarily advise anyone else to do this its just my M.O.
I always use top-quality batteries and I would`t do this with an ego USB style battery/charger but I refuse to get all "battery paranoid" either.

My iPhone stays on a charger on my bedside table and has never blown up and killed me, neither have my laptops which stay on charge constantly when at home and they all use the same battery chemistry as my 18650 batteries.

I have a I2 as well as I couldn't really get my head around exactly what happens with the linked bays with the I4
So if you are charging 4 bats say and battery in bay 1 gets fully charged does the battery in bay 2 carry on at 375mA or go up 750mA?
With the I2 both bays charge at 500mA end of story.

@RSJFT
No you were not misled they will stop charging when the battery is fully charged - in that respect the bays are independent.

From what I understand, charging unattended, charging overnight, and leaving batteries on charge after they're full, when using an intellicharger and reputable batteries, really comes down to trust. Do you have absolute faith that your charger will cut flow to the batteries once they're done? Do you have faith that if something goes wrong you or somebody else will be near enough to react before it gets out of control?

Using a Nitecore or XTar charger and decent batteries reduces the risk of things going wrong, but it can't eliminate the risk entirely. I bought an i4 and I use EFest, AW and Torchy batteries, because I want to minimise my chances of getting into trouble with them. Even with all of these, I don't leave them charging unattended, I don't charge them overnight, and if they finish charging I take them out and put them in plastic cases.

I have my batteries charging in my cabin, which has class A-60 bulkheads and door. If a fire breaks out in here and I get out and close the door, that fire will not progress beyond my cabin for at least 60 minutes. Outside my cabin there are two fire extinguishers: one foam, and one dry powder. It takes us less than six minutes to get our fire teams dressed and mobilised. Despite all this I don't leave my batteries charging unattended.

I certainly don't expect my batteries to explode or my charger to catch fire, and I'm confident that if I forget I have batteries charging and leave my cabin for half an hour then nothing will go wrong, but why take the chance? Convenience is the only benefit of leaving them unattended, and as far as I'm concerned it's not really worth the risk.
