@theconversationau "current prices, online advice suggests the warranty will typically expire before the battery pays for itself."
Who throws away their other household appliances when the warranty expires? You keep using them till they stop working if you've got any sense. If the battery capacity has dropped by 20% after 10y, the remaining 80% capacity is still useful. Why the assumption that the payback lifetime is the warranty period? #HouseholdBattery #TheConversation #GreenEnergy.
