Highly recommended. My girlfriend’s 2001 Prius died at 140K miles. Toyota dealership were quoting $3000. I checked out used hybrid batteries, but most didn’t offer installation or a warranty. Then found HybridBatteryRepair, which was extremely reasonable at about $1600 for a rebuilt battery . Included installation and 6 month warranty. He came to us and it took 1-2 hours for the installation. Also took the old battery off our hands. Prius has been running great since then! Very satisfied.
