Did you manually move or set to Manual and still won’t obey?
Can you tell me how to change the current. I can't seem to get the current to change. I can't seem to get in manual mode.
Set to Manual mode while there is no cell in the bay.
Once a cell/s is loaded while in Manual mode, the charger’s “mA” in the Display should blink, then you can press the “current” button to the mA you wish.
so, Im interested in figuring out the IR of my Eneloops
sounds like this is not the right charger for that job:
I don’t think there is currently a commercial charger/analyzer that can consistently show the correct IR each time, not even my more expensive SkyRC MC3000, considering the inherent drawbacks of using “sliding” rails in order to fit various kinds of cells in the bay, tightness of the contact points, etc., etc. that can affect such IR readings, though they can be just about in the ball-park figure and of course, better than no reading at all of the old analyzers that we have.
….and these manufacturers actually never claim that their product can consistently give the correct reading, each time.
However this is the Vapcell IR tester that I have that can “repeatedly” give out the same IR figure almost each time:
thank you
I need education, considering my first analyzing charger
I have noticed that my old Eneloop, no longer produce as many lumens from my AAA Tool, as my new Eneloop. Im not sure if that is due to IR, or loss of Capacity, or something else
is this S4 a good charger for me to monitor the capacity and resistance (at least to tell new cells from old ones), of my aging Eneloops, as well as LiIon cells?
or would you suggest a different analyzing charger, for my application?
I would say that the current “improved” version of the S4+ will be good enough for your needs.
Thank You 
Happy New Year!
Same to you my friend…in my part of the world 14 hours from now New Year will start.
Greetings to everyone here in BLF!
Vapcell S4 Plus:
I got mines a few days ago. It took me a while to figure it out.
- Small switch located on right side, Manual mode.
- When the cell is in the slot and the charger is plugged into power, press and Hold down the Mode button for two or three seconds, and continue to hold the button down.
- Then you can press the current button button to cycle through the various amp levels, when the current number is flashing. Release both buttons when your choice appears.
- For multiple cells, press the Display button to select the next slot, then repeat steps two and three. You can select different amp charge currents for different slots. Also, this charger fits 21700 protected usb cells. I bought four S4, for my two GT 94s' and MF05 and MT90.
Does that work in all modes such as capacity test. And when capacity test starts discharge do I need to do it again for 1a discharge
And are all 4 slots capable of 3a charge and 1a discharge. And thank you for taking the time to help me. Jim
Yes, max of 3a/slot X 4 slots.
That’s 2 questions in one.
As tatasal mentioned, all 4 slots can do 3A charge current.
But only slots 1 & 4 can do 1A discharge current, while slots 2 & 3 (middle) can do 500mA discharge current.
While on Capacity Test mode, it seems the S4 Plus automatically selects the discharge current to use (I’m not sure if it depends on the selected charge current, or maybe the IR measurement, since for Capacity Test mode, only the Charge current is user selectable, assuming in “Manual” mode; the Discharge current is automatically chosen by the charger).
However, one can manually set the Discharge current when using the “Discharge” mode (outer 2 slots max 1A discharge current and middle 2 sltos max 500mA discharge current).
I think mine just blew up. With one battery in channel one, it showed all four channels charging, and there was a burning smell. I have turned it off
That sounds very close to my misfortune with my Vapcell S4+ only 10 months old, good luck trying to get it replaced under warranty……
I had an AAA battery blow up in ch4 and the charger developed issues after that, which does d not end well. I suspect the battery going bang damaged things.
I only used mine to charge the 18650,21700,26650 and one day it just refused to work and died.
When power is applied the screen back light comes on very dim and you can not see anything that is normally displayed,
when i insert a battery in any of the slots the display turns a little brighter and when viewed from an angle i can see a very dim outline of the functions,
however there are strange things happening, no matter the slot i choose using one battery the charger never shows the proper slot information where the battery is inserted it shows that there is nothing in that slot but it shows 1 or 2 different slots without any battery in them that these slots are charging.
When I insert 4 batteries everything goes blank even the dim back light goes out.
I purchased vapecells4plus, and it works very well. The only issue is that batteries must be put in correctly. To get accurate readings.
I really wish the sound it makes when a cell is finished charging could be turned off, it drives my dog nuts.
I don't think it is supposed to make a sound.
