Engineered for Heavy V-Twin Cranking & High Vibration

Harley-Davidson motorcycles demand significantly more starting power than standard street bikes. Large-displacement V-Twin engines require massive initial surge current (high Cold Cranking Amps / CCA) to turn over heavy pistons against high compression.

Standard motorcycle batteries often suffer internal grid separation caused by intense engine vibration and high operating heat. At Battery Brands Warehouse, we stock specialised Heavy-Duty AGM and Lithium V-Twin batteries featuring:

• Reinforced Heavy-Cast Lead Grid Construction: Prevents plate shorting under heavy engine vibration.

• Low Self-Discharge Rates: Perfect for weekend riders and seasonal storage.

• Factory Sealed & Maintenance-Free: Leak-proof design allows multi-angle fitment without acid spills.

Frequently Asked Questions

Q: Can I upgrade my Harley-Davidson battery to Lithium?

A: Yes! Lithium (LiFePO4) motorcycle batteries offer up to 60% weight reduction and up to 50% higher starting cranking amps than standard AGM batteries. However, you must ensure your battery charger is lithium-compatible.

Q: Why do Harley V-Twin batteries fail earlier than standard Japanese bikes?

A: Large V-Twin engines require extreme cranking current, putting heavy strain on internal plates. Additionally, high vibration and heat from the air-cooled engine accelerate battery wear. Using a dedicated V-Twin Heavy-Duty AGM like the Motobatt Quadflex or SSB DryCell HVT series solves this issue.

Q: Is the battery charged and ready to install immediately upon pick up?

A: Yes. All our motorcycle batteries are factory-activated, fully sealed, and tested prior to pick up or dispatch so you can bolt it straight into your Harley and ride.
