As a starting battery. Did you put it in under the passenger seat ?
My mechanic recommended it because I seem to have a parasitic drain somewhere (radio for sure but maybe another). He stated that ~for now~ it would be good to do, then when we find the issues I could move this to a 2cd battery system (house battery).
 Its a stop-gap for this month.
