My Vapcell S4+ Analyzing Charger photos and observations

Batteries and Chargers Chargers

I am seeing 50% higher shipping cost than what you found — $8.41 to Dallas, TX for USPS Ground.

I’ve ordered this charger, and I have some questions (I’m a noob and this is my first charger).
My batteries are only Ni-MH (eneloop and noname).

- When battery fully charged (100%), should I seen on the charger the therorical capacity of the battery (for example, if I charge an AAA eneloop 1.2V 750mAh battery, when then battery is full charged, should I read 750mAh on the charger ?)

  • How to read resistance (mOhm), I’m currently charging 4 AAA noname batteries 750mAh, 2 was in error, and I’ve used the repair fonctionnality to charge them, All of them are reporting different resistance values (from 200 mOhm to 999 mOhm) ?,

And I also have a general question :

- I heard that Li-Ion battery exist, they never sold in regular shops, so can we replace a Ni-MH battery with a Li-Ion, is there some exceptions ?

  • Using which criterias you decide to recycle your batteries ?

Thanks

Charging mode only reports how much it puts into the battery. If you want to check that use the Cap Test mode. Do note there is an issue with this charger in that mode where it won’t really fully recharge NiMH cells at the end of the test despite it saying they are 100%. I just do a Charge mode on any cell right after the Cap Test is done.

Take the milli-ohm values with a grain of salt but higher numbers generally aren’t a good indicator of battery health.

Li-ion cells have a nominal voltage of 3.6V while NiMH cells are 1.2V — so they are completely different and not simply interchangeable! You really should do some research…

I have some older low self discharge cells that no longer can even handle just a 250mA discharge rate, but I can still use them in some of my LED flashlights. For some flashlights I use 3AA-to-D parallel adapters to make use of my older cells.

Thanks for your answers.

I charged many batteries and on two of them the charger was filling the battery much more (4000 mAh) than the theorical capacity (2700 mAh). The battery was very hot when I removed it from thé charger… I think this very dangerous !

I can’t charge battery on night or when I’m at work, I’m not very confident …

I have noted a similar behavior (both on this charger and my old LaCrosse BC-900) with old worn-out batteries. Maybe try the Cap Test or Repair function on those cells.

69

Can you give us some information on the batteries that you were trying to charge with this charger? Also, how old are the batteries?

70

Too bad it has only .5A on 2 discharge slots.

I would of really liked it to have at least 2A discharge on each slot independently.

71

But then the charger should need perhaps 2 high-volume fans to manage the heat generated at 2a x 4 !

72

Not a problem; I’m really looking for a multi-slot high current tester. Let the cooling be handled by me.
Most testers I generally found are .5A on discharge test which is utterly useless for any high current cell.
Opuses can do 1A on all slots (and needs modded cooling). Did not find anything better so far.

73

SkyRC MC3000 can do 1x 2A discharge, or 4x 1A discharge.

I’d really like for the MC3000 to be able to at least do 4x 1.5A, and hopefully make a variant compatible with longer protected 21700 batteries…

Folks:

I bought this charger 2 weeks ago and have put it through its paces. My impression thus far is it does very well. Appears to be accurate. Build quality is “ok”. About standard for the course. My ONLY issue is the power supply. It is noisy. I can hear a constant buzz when not plugged into the charger and when plugged in and charging a cell you can hear a pulsing sound. Not good. Almost too noisy to share my office. I might have to start looking for a quality 12V 5.0A = 60 Watt charger that is quite as this buzzing is problematic for me. Anyone know where I can buy a decent build power supply?

75

I use this type:

Similar for 5V, 30+A.

@tatasal
Got this charger less than a year ago and it worked great for my needs.
The other day went to charge some batteries and the screen was blank.
Long story short I am looking for a new charger since this one is dead.
Sent email and pm to Neal however got no response if it is covered under warranty.

77

Dennis of Vapcell, who is also a member here, just said they have 1-year warranty as long as the the damage is not “man-made”.

Thank you for the update, silly question how do I get hold of Dennis?

Update:
Just sent a pm to Dennis.
Thank you @tatasal.

I received my s4plus today.I can't change current. I do what instructions say. Charger says its in 3a current but then goes down to 157ma. Seems like Charger doesn't go into manaul. Can anyone please help. Thanks Jim

Did you manually move or set to Manual and still won’t obey?

81

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.

82

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.

83

so, Im interested in figuring out the IR of my Eneloops
sounds like this is not the right charger for that job:
