66007-84 Harley Davidson Battery Replacements
The Harley Davidson part number 66007-84 has not been upgraded since inception. However, several aftermarket manufacturers have improved upon the original Yuasa specs of the YHD-12 as it was also known. These upgrades are sealed lead acid AGM batteries.
Remember to take into account that the CCA is not the only metric you should pay attention to, the Ah is vitally important and arguably more important for a Harley motorcycle. If you can increase both these numbers from what the OEM specs indicate you know you have a solid battery that will stand the test of time. The sealed maintenance free UBVT-7 and MBHD12H are our top replacement batteries.
