10. Cycle life varies depending upon application-specific
characteristics. Actual results will vary.
11. Per United Nations material classification UN3499, all
Maxwell ultracapacitors have less than 10 Wh capacity
to meet the requirements of Special Provisions 361.
When packaged according to the regulation, both
individual ultracapacitors and modules composed
of those ultracapacitors shipped by Maxwell can be
transported without being treated as dangerous
goods (hazardous materials).
