MTP are 30 months 100% warranty, pro-rated out to 85 months
MT are 24 months 100% warranty, pro-rated out to 75 months
I are 18 months 100% warranty, pro-rated out to 65 months.
Formula for pro-rate cost to us and charge to customer:: months battery lasted x Adjustment amount(list) or (cost)
Adjustment amount is found by dividing total months battery is pro-rated for (i.e. 85) by the list price (can be found at interstatebatteries.com or on pricing sheet) or what it cost us.
