Charger Question

[Mr_Phil]

Hi.

Can someone point me to a resource where I can get educated on how batteries and chargers work?

I currently have 4 of the green 4.8v nimh 600mah batts from madvapes.
I also have two of the blue 3v 1250mah lipo from madvapes
and finally two of the red Vmax IMR 18350 batts from Madvapes. These are 3v as well.

I bought HG-1412-W 4 Cell Li-Ion Charger from Madvapes

The description reads:

HG-1412W Battery Charger. This is a universal charger that comes with a wall plug and has four charging channels. It has a switch that allows you to change charging modes.

These include:
1. is for Ni-MH/NiCad batteries.
2. is for rechargeable alkaline batteries.
3. is for LiFePO batteries.
4. is for rechargeable Li-Ion batteries.

1200 mAh output at all voltages so it charges batteries fast. Easily fits 18650, 18500, 18350, 14500, 17670, 10440, 16340 and CR123. Plugs directly into a wall outlet and has a seperate LED to provide charge status for each channel. AC cord is about 2ft long. Easy to use and operate. Color may vary.

I noticed that the unit has voltages next to the numbers. So, for example, position four on the charger reads 4.2 volts. According to the MV blurb position 4 is for lion bats. So, does that mean that it will kill the 3v batts? Likewise, position one on the blurb is for NIMH but on the charger position one reads 1.2v. So, which position should I charge my green batts on?

I freely admit I am really confused. And, just to be clear: I have no beef with Madvapes. They are pretty much my fav ecig vendor bar none. But, I am really getting tired of experimental mix and match batts for my bolt. i like the hotter hit from the higher voltages on a 2 to 2.5 ohm tank.

And, I tried charging the 4.8s on the 4.2 setting. In no time flat they showed charged. And they were obviously weak when tested. The 3v batts take a fast charge on the 3.5v (position 3) spot. But they also only last an hour or two afterwards.

I need to figure this out. Any and all help appreciated.

On the charger it reads

4. 4.2v
3. 3.5v
2. 1.5v
1. 1.2v

Follow MVs recommendation. The 4.8V batt is 4 x 1.2 in series and requires to be charged at the 1.2V setting. That being said, not all batteries are created equal.

A resource that covers a lot of info is Battery University.

m'kay. I put them in the charger at 1.2v and it instantly shows them to be charged (all red LED's out, green led lit). Thanks for the tip.

A lot is right. Thanks. Guess I need to study up on it.

You won't be able to charge those with that charger, none of the positions provide enough voltage.

You will need an output voltage of about ~5.6V to charge these properly.

And FWIW don't confuse LiPo with LifePO. Different cells.
