e.g. in case of 2.7V 10F cell, charge with 10 * 10 = 100 mA and discharge with
40 * 10 * 2.7 = 1,080 mA
4. Maximum Leakage Current
• Current measured after 72 hrs at rated voltage and 25°C. Initial leakage current
can be higher.
• If applicable, module leakage current is the sum of cell and balancing circuit
leakage currents.
5. Maximum Peak Current
• Current needed to discharge cell/module from rated voltage to half-rated
voltage in 1 second.

9. Per United Nations material classication UN3499, all Maxwell ultracapacitors
have less than 10 Wh capacity to meet the requirements of Special Provisions
361. Both individual ultracapacitors and modules composed of those
ultracapacitors shipped by Maxwell can be transported without being treated as
dangerous goods (hazardous materials) under transportation regulations.
