I finally found the answer: http://endless-sphere.com/forums/viewtopic.php?f=14&t=12272&p=183200&hilit=us18650ft#p183200 "Re: New Sony Olivine-type Lithium Iron Phosphate Power Tool Cell Postby Doctorbass » Thu Aug 13, 2009 3:57 pm hmmm.. Interesting to see Sony decided to invest again the the old great 18650 platform... Their last succes is still the LiMn 18650V and the 18650VT ( aka K O N I O N ) According to the Specsheet I have from them, The V can take 10C and have 1.5Ah (15A burst 7A continuous) for 3.75Vnom 500 cycles at 1C 80%dod 43g The VT can take 15C and have 1.1Ah (17A burst 8A continuous) for 3.70Vnom 500 cycles at 1C 80%dod 43g compared with : The FT that can take 18C and have 1.1Ah ( 18A continuous) for 3.2V 2000cycles 40g" Different voltages, so I can not use the DeWalt batteries in the Makita battery pack.

I have a Makita BL1815 Battery Pack with a #1 dead cell. It uses Sony SE US18650VT cells. I have a donor DeWalt DC9181 Battery Pack, which has Sony SE US18650FT cells. I can find the specifications for the Makita SE US18650VT cell, but not for the DeWalt SE US18650FT cell. So, I am wondering if I can use the DeWalt SE US1860FT cell to repair the Makita SE US18650VT battery pack. Thanks for your expertise!
