Several: This are designed for race applications, as such they list CA or cranking amps, not CCA or cold cranking amps, which is what is important for street applications in cold environments like yours. The use a different charging profile than the alternator in your car is set for, and they have an extremely limited disposal/recycling chain (Li poisons lead, so they cannot be recycled together).

You can save some weight (7-10 lbs.) without all the above issues by going with an AGM battery such as the Optima or Odyssey, which are meant for street use in cold climates.
