wp2ii charger

So I have the xtar charger and im charging my battery (awimr 2000mah) should I have the output at .5 or 1. ? Thanks = )

For 2000 mAh batteries - easily the 1 amp switch position. Any battery 1000 mAh or lower you definitely want to put the switch in the 500 mAh position. Most of my batteries fall to extremes anyway so there isn't a lot to figure out. My 18650's are all 2 amp or higher so 1 amp position. Any of my 14500, 16350's etc. are 900 mAh or less - so all those get the .5 position.

ETA: The bottom line is you never put more charging current into a battery than it's rated ouput. Charging a 2 amp capacity battery at only 500 mA - not a problem - it just might take longer. But charging an 800 mAh battery at 1 amp - PROBLEM.

The "0" position is for using the WPII 2 as a charging device. With the charger unplugged put an 18650 battery in slot 1, connect the device you want to charge to the USB port.

Thanks again ! Your info is always helpful!

This may be a dumb question, but please humor me ... is the AW IMR battery a Lithium-ion battery? The XTAR WPII 2 clearly says it's only for Lithium-ion batteries. Just wanted to clear that up in my own mind since I'm confused about IMR chemistry designation.

It is, and that battery will charge safely on the WPII.

IMR means it is a Lithium Manganese chemistry, which is safer than the Lithium Cobalt, or ICR, chemistry.

Follow Rick's advice on what current to set the charger on.

I charge 18350's & 18650's on mine. I just leave it on .5 just to be safe. If all your charging is the awimr 2000mah, then 1.

Thanks for your clarification .... much appreciated!

Lithium Ion (Li Ion) is a large class of batteries, which has a few sub-classes within it.

• Li Mn is a safe chemistry & high drain class, currently the recommended battery for use in all mods. AW IMR's fall in this category.

• Li Cr, Li Ni, Li Co, and LiNiCoMnP all have slightly different chemistries and still considered Li Ion. Most of these are called "protected" Li Ion because being a more volatile chemistry require a protective circuit built into the battery. Typically have higher capacity (mAh) than Li Mn, but without the maximum load current attribute (amps/high drain) Li Mn has.

• A new class called a hybrid is being made by Panasonic and Sony. These companies do not disclose the chemistries publically, but are said to have high drain attributes as well as high capacity and protection.

Just a side note, I use 2 Panasonic hybrid CGR18650CHs and a i2 Intelli-charger and couldn't be happier with the results. In case anyone is wondering how they work out.... pretty damn good!
