I have a 2009 Lexus GS 450H, although Lexus tell me it was manufactured in 2007. The hybrid battery appears to be as good as new, but how would I know, and what is the expected life of the battery? Anyone had experience with these? And any suggestions on where to buy a new battery if needed - I have heard buying through Lexus is very expensive?

Welcome!

 

Thanks Matt for directing him to that. Welcome friend. Why would your car be a 2007 if Lexus says it was manufactured in 2007? Would that not indeed make it a 2007?

Either way, the expected useful lifespan for the Nickel-Metal-Hydride (NiMH) battery pack is 10-15 years on average. Costs to replace can be dizzying so I reccomend having your local Lexus/Toyota dealer check the hybrid system health before you purchase and periodically after.

 

Mine was an 07, but actually manufactured in March 06...
The 1st 450hs were weird with builds. Remember, Lexus treated it as a sorta open base beta program for the US those first 2 years.

 

Thanks Army of one. The car was first registered in 2009 in England - ostensibly making it a 2009 car. However, I now own it after being exported to New Zealand and Toyota NZ say it was manufactured in 2007, so I imagine that is the actual age of the battery.
