<![CDATA[75,000 km Long-Term Ownership Review: 2023 BYD Atto 3 Extended Range — Blade Battery SOH (97.5%), Servicing Costs & Wear Items]]>Just ticked over 75,000 km (46,600 miles) in our Surf Blue 2023 BYD Atto 3 Extended Range (60.48 kWh) here in Melbourne, and since I started logging every charge and service on Day 1, here is the brutally honest long-term report card.

75,000 km Long-Term Ownership Review: 2023 BYD Atto 3 Extended Range — Blade Battery SOH (97.5%), Servicing Costs & Wear Items

1. Blade Battery Health (SOH) at 75,000 km

Plugged in my Vgate vLinker MC+ OBD2 dongle with CarScanner Pro this morning after a full 8% → 100% AC calibration charge:

  • BMS Reported State of Health (SOH): 97.5%
  • Cell Voltage Delta at 100%: 0.006V (6 millivolts across all 126 LFP cells — basically factory fresh!)
  • Charging Habits: ~80% home 7kW solar/off-peak AC charging (charged to 100% twice a week), ~20% DC fast charging on highway trips down to Geelong and Gippsland.

2. Total Maintenance & Repairs Over 75,000 km

  • 20k, 40k, 60k Logbook Services: Stuck to the capped-price schedule (brake fluid at 40k, reduction gear oil at 40k, cabin filters I swap myself in 2 minutes behind the glovebox for $18).
  • Tyres: Swapped the terrible factory Atlas Batman A51 tyres at 24,000 km for Michelin Primacy 4 ST (235/50R18). Still have 4.2mm tread left on the Michelins after 51,000 km!
  • Brakes: Original factory pads still have 7.5mm of meat left because regenerative braking does 90% of the stopping.
  • Warranty Claims: Had the 12V auxiliary lead-acid battery replaced under warranty at 31,000 km, and the driver's interior door pull cable adjusted once. Zero drivetrain or HV faults.

Some people try to skip it, but draining the initial break-in metallic sheen off the magnetic drain plug on the electric drive unit keeps the gearset whisper-quiet for the life of the car.

We're at 55,000 km on our 2023 Atto 3 down in Christchurch NZ (including freezing South Island winters) and our OBD2 SOH reads 98.1%. Haven't noticed a single kilometre of real-world range loss.
