ML-102 charger

About the ML-102 charger:

I bought one King Kong INR 26650 raised top and (2) ML-102 chargers. The raised top cells do not like to sit in the ML-102 charger very nicely. The raised top of the battery slides up off the positive terminal of the charger (because the terminal just barely hits the edge of the raised part). Seems the charger is really sized for 18650's.

Anyone else using this combination? Seems to me that for use with these raised top cells it would be best to file off some of the chargers rolled side (the way it's rolled to fit an 18650) to allow the 26650 to sit down lower.

Here's a photo trying to show the issue:

It's tough to see the chargers positive terminal, but you can see how the cell is raised up off the "rolled edge" of the side of the charger.

King Kong Raised Top INR26650's: Total length 68.05mm, diameter 26.33mm. Battery is a tight fit in the ML-102 charger with just a mm or two to spare.

Charged up my King Kong INR26650 and terminated at 4.19v measured with a cheap DMM. I then disconnected from the wall adaptor and plugged in my iPhone 3GS to see if it would start charging and it didn't at first. I removed the battery from the charger and placed it back in and it finally started charging.

Here's a photo showing my temporary solution to the raised top cell popping up out of the cradle (a rubber band):

I don't see any reason that I can't file down the rolled edges of the charger to better accommodate this raised top King Kong. I can leave enough of the rolled edge to still firmly hold an 18650 (maybe file the edges down at the top and bottom to about the same level as the middle.
