I bought a brand new OEM replacement battery (G9510-47020) on August 11, 2018 from a Toyota dealer (cost ~ $2,000). I installed it in my '02 Prius and it works great. Then a tree fell on my Prius and it's totaled (completely caved in roof, bent doors and both rear quarter panels). But the new hybrid battery is still great. Less than 600 miles has been put on car since the battery was installed. Charge has been maintained since the tree hit it (Nov 10, 2018) by starting and idling the car for 20 minutes twice a week. I really don't want the hassle of shipping this battery, so hoping to find a local buyer near Clarksville, Maryland. Asking $1200 (includes the original internal electronics modules too - they don't normally come with the replacement battery). I can even install it for you for a little extra if need be. Would consider delivering the battery if it's not too far away.
