Ultrafire WF-138 Charger and 18350 Batteries

[deviations]

Does anyone know if the Ultrafire WF-138 switching charger can charge 18350 batteries? I know these batteries are 3.7v and the charger can output 3.6v. I didn't think they were compatible but saw the battery and charger bundles on sale at a few places.

Does anyone have this charger and can comment?

I don't have that particular charger, but I do use several of that size of battery. The Ultrafire WF-138 seems to only charge CR123A and 16340 batteries, according to the vendor's description.

The Ultrafire WF-139 - Battery Chargers : Ultrafire WF-139 will charge 18350 batteries and is just a couple more dollars than the one you listed.

I charge my 18350 batteries either in a Pila or Xtar MP2.

A downside to the MP2 is the spring-loaded charging bays; the batteries must be inserted very carefully or the flimsy springs will bend sideways. The Pila's charging bay is much easier to insert/remove batteries because of the spacers it uses, and it charges the batteries possibly twice as fast as the MP2 does. It's been said that the Pila also uses a charging algorhythm which can prolong battery life. I have had the Pila and a couple of AW IMR 18650 batteries for a year and both are going strong good as new. Well worth the extra money to me, if you can spring for it.

Xtar MP2 does look good for the price. Picked that up along with some Efest IMRs. Thanks.

I like and use the NiteCore i4 or the i2. You don't need spacers for the 18350s or the 16340 batts.

I agree with sashwa. I have the i4 (4 bay).
