electric bike battery replacement cost

In Australia, replacing an e-bike battery typically costs around AUD 400–1,200 for common 36–48V packs, with premium or high-capacity units nudging AUD 800–1,500.

Proprietary systems (Bosch, Shimano, Yamaha, Specialized) usually sit at the higher end, while off-brand packs are cheaper but can be a false economy.

Used batteries do pop up for roughly AUD 150–600, but expect reduced range and a shorter remaining lifespan.

Factor in AUD 50–150 for fitting if you’re not DIY-inclined, plus proper recycling of the old pack.

If a price seems too good, it probably is—buy from reputable sellers and match voltage, capacity, connectors, and BMS specs to your bike.
