I'm waiting on my 3400mah Panasonic cells to come. Looking at the specs they do seem slightly longer than some other 18650's. if they don't fit I will use jumper wires soldered to small magnets and attach them to the cell. Or jump the leads on the charger to a piece of wood with screws or metal posts and make my own battery holder.

Looks like charger is large enough to accommodate larger cells. I will see in 2 more days when the 18650s arrive.
Xtar WP2 ii specs.
Charges any lithium cell that can fit, in the battery bay, 50 to 70mm length, and shorter cells with spacers (were not included in sample)
16340, 14500, 14650, 17670, 18500, 18650, 18700
Charge rate selectable at 500 or 1000mA max current
12V input
Usb type A socket output up to 500mA (powered by battery bay 1)
However this spec listing says the charger can't handle over 68mm cells.
The XTAR WP2 II charger is a dual bay rechargeable lithium battery charger released by XTAR in mid 2011. It offers 2 independent charging bays which can take cells 50-68mm in length, and cells shorter than that with suitable spacers. This means cells from 14500s, up to practically all protected 18650s will fit. The XTAR 18700s (68mm long) are also accepted in this charger.
