What is Second-life Battery?

It retains useful capacity. It stores solar or grid energy. It extends use before recycling. A car battery that has dropped to around 70 to 80 percent capacity may no longer meet range needs but can still store energy for homes, businesses or the grid. Projects use second-life batteries to buffer fast chargers. Each battery must be tested and integrated with suitable safety electronics.

How it works

Modules are tested and reused.

Why it matters for your car

Quality varies. Safety systems are needed.
