What is this?
This is a DIY kit to completely and fully replace your aging or dead Lexus GS450h Hybrid Battery (a.k.a. Traction Battery) with brand new battery modules, bus-bars, battery wiring harness, and interconnects. You retain your original metal enclosure and hybrid ECU.
Will this work with my Vehicle?
This is meant for Lexus GS450h vehicles, model years 2007 through 2012. These modules will work in any number of Lexus, Toyota and other makes that use the same Panasonic battery design, but the wiring kit is specific to the Lexus GS450h. With extra (and non-supported) DIY, you could potentially make it work with many more vehicles.
Brand New Batteries: Not a refurb or rebuild. These are brand new modules fresh out of the factory and have never been in a vehicle. ZERO miles driven.
Superior Design: Cylindrical cells, half the battery modules, and all the same functionality. Upgrade your Hybrid Pack today!
Factory Warranty: A 2 year or 25,000 mile warranty on the modules. Fleet vehicles included.
For $2050and 4 hours of installation time, you will get a brand new hybrid battery backed by a 2-year or 25,000 mile warranty including fleet vehicles. There is nothing comparable out there. All other options that are not original Lexus/Toyota Hybrid packs, are used modules. Some are refurbished and/or balanced to be better matched with one another, but they are still all used batteries from wrecked, salvaged, totalled, or other failed Prius vehicles. In contrast these batteries from NewPriusBatteries.com are brand new and never used. When you start driving on your new pack, it starts with zero miles on it, just like a brand new Prius from the factory.
The Smarter Financial Investment
Don't waste your money on refurbished or remanufactured batteries. The only real solution to repair your Toyota Prius Hybrid Battery is to replace the entire pack. Anything else is a temporary band-aid, akin to playing the game whack-a-mole. Why spend the same money to put in used modules inside a refurbished pack instead of buying new modules from us? Our batteries at NewPriusBatteries.com are the smartest choice for any Lexus/Toyota Prius needing a Hybrid Battery pack replacement.
The NewPriusBatteries.com Hybrid Battery is different than an original Lexus/Toyota Hybrid Battery, but it is made to be interchangeable. The largest differences and features are highlighted below
Half the Modules: An original Toyota pack uses 40 modules paired into 20 blocks. We've simplified the design and now you just need 20 larger modules making the same 20 blocks. (There are more in the Lexus GS450h than the standard Gen2/Gen3 Prius)
Fully Compatible: Designed to be 100% backwards compatible with the original modules. Uses the same wire connectors, same mounting, same temperature sensors, same enclosure.
Factory Warranty: A 2 year or 25,000 mile warranty on the modules
Cylindrical Cells: These cells are shaped like a series of large D-Cell batteries instead of the rectangular bricks of the original.
New Bus Bars: The kit comes complete with new solid metal bus-bars to connect adjacent modules together, new nuts, and new wiring.
No Core Charge: When you order, you get your battery pack kit. There is no extra charge for a core, and no deposit required. Your old parts can be saved or sold to offset the cost.
Standard Installation Flow
These kits are no more difficult to install than a standard battery swap. In fact, it is recommended to follow one of the many YouTube videos of how to disassemble your Lexus GS450h to access the Hybrid Battery and to put it back together.
Disassemble Prius to Access Hybrid Battery
This involves removing the false floor, some interior plastic panels, and disconnecting the rear seats. All can be done with a socket wrench and a screw-driver. A power-drill is recommended with a socket attachment to make life easier. Average time for a first-time disassemble is roughly 1 hour. An experienced rebuilder can usually do this within 5-10 minutes.
Remove Hybrid Battery from Vehicle
This is a heavy part, it is best to have help. You will need to access the bottom of the pack, so it does need to be fully removed. It cannot be worked on in the car.
Disassemble Original Hybrid Battery
Remove the cover, remove the battery nuts, remove the bus bars, disconnect the venting, disconnect the temperature sensors, remove the tension bar, and end up with the shell of a battery. Since there is no core charge, you are welcome to keep your old modules or to sell them on eBay for others venturing to make refurbished used packs to help offset the cost of your brand new pack! Remember if you ever intend to extract a core exchange fee, you will need your original modules at this time.
Assemble NewPriusBatteries.com Brand New Hybrid Traction Pack
Line up your modules in serial order. Each of the 20 modules are marked from #1 through #20, and put them in order. Attach the bus-bars, battery nuts, and new wiring harness. Move battery to original enclosure. Attach temperature sensors via included clips. Attach modules from the bottom to the original battery enclosure. Complete the wiring, and put the cover back on the battery. That's it! Average time for a first install is about 1 hour if you are taking your time.
Re-Install Hybrid Battery in Vehicle
Again, this is a heavy part and it is best to have help. Carefully place the newly assembled battery back into the Prius.
Reassemble the Prius
Now it is time to put all the bolts, screws, and plastic panels that make up the rear of Prius back together. This may take an hour for a first time builder, again 5-10 minutes for an experienced installer.
Make sure to latch the orange safety interconnect back in-place (it can be tricky!) and READY the vehicle. If you have codes, it is best to clear them before driving. Your brand new battery is now installed and should be trouble free and worry free for a very long time. You also have the peace of mind that your brand new battery from NewPriusBatteries.com is fully warranted for 2 years or 25,000 miles, whichever comes first. In the unlikely event of a warranty replacement, we will send you a new battery module for you to install.
