Instructional video to replace the cells in a snap on 18v CTB7185 4ah and CTB8187 5ah packs.

Spot welder time (strips to cells) 45ms, (strips to strips) 15ms.

The original CTB7185 cells are 2000mah, to give a pack capacity of 4ah. The new cells are 3200mah to give a pack capacity of 6.4ah.

Sorry for the audio and camera angle, this is my first instructional video.
