NOTE: The power output of this charger is incorrect for the protected 3V 750 & 900mah RCR123A cells that we carry. We specifically do not recommend using this charger for those cells. Only use this charger with 3.6 & 3.7V cells.

NOTE: Use special caution when working with Li-ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure the user has enough knowledge of Li-Ion rechargeable batteries in charging, discharging and assembly before use. Always charge in/on a fire-proof surface. Never leave charging batteries unattended. We are not responsible for damage if there is any modification of the batteries/chargers in any form or shape (including pack making). We are not responsible for any damage caused by misuse or mishandling of Li-Ion batteries and chargers. We only recommend using Lithium Ion rechargeable batteries with a control circuit (protection PCB) to assure safe charge, discharge, etc., use of lithium ion batteries with a protection circuit is potentially hazardous

Works great
It works as advertised. Got to drain the batteries all the way down for better reconditioning. The batteries will last longer

Faithful For 4 years And Going
I've been using this charger with (2) 2200 mah 18650 batteries for over (4) years now. It has worked faithfully every time. It has the ability to charge quite a few other size batteries too but I have never had to use for any of those sizes. Since I have never experienced any failures, I would recommend it to anyone that may ask me.

Lion Charger Battery
The charger and batteries are great. I am using mine to power a 1 watt hand held laser. The charger is easy to use. It charges the 3000mah Ultra fire batteries too.

1 Question & 1 Answer
from Whitesboro, NY asked:
November 19, 2014
I have purchased the KLARUS XT 20 which runs off of 2x 18650 or 4x CR123A's. Does this COMBO UltrFire 18500 1600mah 3.7v batteries run the Klarus X20? Does the Ultrafire WF-139 Lithium Ion Charger / 2 Ultrafire 18500mah 3.7v battery charger run off of both AC and DC? If not is there any other 18650 rechargeable batteries that you recommend with a dual AC/DC charger? Please let me know .Randy Wilcox
1 Answer
No, the Klarus XT20 is not compatible with 18500 li-ion batteries, only 18650 cells. The UltraFire WF139 battery charger does not include a DC car charger, only an AC wall charger. We do carry a Nitecore 12V DC Car Cord that is compatible with the Nitecore i2 Intellicharge Charger, Nitecore i4 Intellicharge Charger, Nitecore D2 Digicharger Charger, and Nitecore D4 Digicharger Charger. These chargers will charge li-ion 18650 batteries.
