Battery Degradation Simulator

All batteries lose capacity over time. This simulator shows how different batteries degrade over their warranty period, helping you understand true long-term value.

Capacity Over Time

Tesla Powerwall 3

BYD HVS 12.8

Key Milestones

Tesla Powerwall 3

Chemistry: LFP | Warranty: 10yr

Below 80%: Year 12 | Below 70%: >15yr | Below 60%: >15yr

Est. lifetime throughput: ~54MWh over 15 years

BYD HVS 12.8

Chemistry: LFP | Warranty: 10yr

Below 80%: Year 12 | Below 70%: >15yr | Below 60%: >15yr

Est. lifetime throughput: ~52MWh over 15 years

Degradation rates are estimates based on manufacturer specifications and chemistry defaults (LFP: 2%/yr, NMC: 3.5%/yr, LTO: 0.5%/yr). Actual degradation varies by usage patterns, temperature, and depth of discharge. Perth's warm climate may accelerate NMC degradation but has minimal impact on LFP.
