Abstract
A battery may have a foil battery pack with leads that are coupled to a printed circuit board. Battery protection structures formed from an insulating material such as plastic may be used to protect the foil battery pack. The foil battery pack may have a rectangular shape with front and rear faces surrounded by a rectangular peripheral edge. The battery protection structures may have a ring shape that surrounds the peripheral edge while leaving the front and rear faces exposed to minimize the size of the battery protection structures. An elastomeric material may be used to form the battery protection structures. The elastomeric material may allow the battery protection structures to stretch when the battery pack expands during use. Two shots of plastic may be incorporated into the battery protection structures to provide both puncture resistance and the ability to stretch during use.
