Clear answer
Clear answer, explained.
The exact lifespan depends on system design, operating conditions, and how frequently the battery cycles (charges and discharges). Manufacturers generally provide 10–15 year performance warranties , while many systems continue operating for up to 20 years with proper maintenance. Maintenance is relatively minimal and focuses on monitoring system performance, inspecting electrical connections, verifying cooling and safety systems, and updating software or firmware. Many systems are monitored remotely 24/7 to detect issues early and ensure reliable operation.
Key points
