While a new EV battery might cost $150–$250/kWh, a repurposed "second-life" battery can drop to $44–$180/kWh.
Repurposing keeps critical minerals like lithium, cobalt, and nickel in use longer, delaying the need for destructive new mining. The Ethical Weight of E-Waste buy used batteries
Used batteries often have a lower Depth of Discharge (DOD) —perhaps only 50-60% compared to 80% for new units. This means that while the upfront price is lower, the cost per usable kilowatt-hour can actually be higher over the battery's remaining life. The Environmental "Second Life" While a new EV battery might cost $150–$250/kWh,
The deepest argument for buying used batteries is ecological. For lithium-ion batteries, the vast majority of their carbon footprint is generated during . By extending a battery's life through a second owner, we amortize that initial carbon debt over a longer period. Carbon Reduction: Using second-life systems can reduce CO2cap C cap O sub 2 This means that while the upfront price is
From a purely financial standpoint, the decision to buy used is driven by a stark price difference. Pre-owned batteries typically cost than new ones. However, this "discount" comes with an invisible tax: uncertainty .
