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).
