High compression increases starting load, but a battery is never a universal Harley part. Match the exact OEM part number or battery group, physical length x width x height, terminal orientation and hold-down before comparing CCA. Do not substitute peak-current or PHCA figures for CCA: the products below state CCA separately where published.

- Published period-specific Touring application
- Maintenance-free sealed format
- Listed application is limited
- Not a blanket replacement for later Touring bikes

HVT-2 AGM Harley Battery
An AGM replacement type cross-referenced to Harley 66010-97, with a published 450 CCA and 169 x 131 x 175 mm case. It is a candidate only where that physical footprint and terminals match.

HVT-6 AGM Harley Battery
An AGM type cross-referenced to Harley 66010-82 with 300 CCA and a 203 x 88 x 162 mm case. It is a dimension-specific option, not an upgrade path for a different original battery group.
- 300 CCA
- 203 x 88 x 162 mm case
- Published OEM cross-reference
- 23 Ah nominal capacity

- Fitment is case- and terminal-specific
Odyssey ODS-AGM28L PC925
A 12 V AGM battery with separately stated 330 CCA and 900 PHCA figures; do not confuse the latter with CCA. Its 168.7 x 179.1 x 148.1 mm case and M6 or SAE terminals make fitment a physical check.
- 330 CCA and 900 PHCA stated separately
- 168.7 x 179.1 x 148.1 mm case
- Published CCA avoids peak-current substitution
- 28 Ah nominal capacity

Buying tips
- Test voltage drop and inspect grounds, starter cables and automatic compression releases before blaming the battery.
- Use the battery maker’s approved charger and follow its lithium or AGM charging limits; a higher number cannot overcome incorrect fitment or a weak charging system.
