04 Prius battery replacement Puerto rico
I bought a battery kit for my Prius in Puerto Rico. I don’t put a lot of miles on the car but has given me flawless performance since I installed it about a year and a half ago. I installed it myself with no real problems in less than a day. Technical support was great for the one question I had. I would definitely recommend this product! Thanks, Jeff
Jeff kuckukJan 12th 2019
Great product. Installed according to directions and started the car. No codes and runs great.
Would give 5 star but took a while to receive and the black plastic covers were broke in the package. They give you some extras, but was still short two. I just used some pieces and tape.

Gen2 battery rebuild kit
Kit arrived a week early in good condition. I was able to rebuild the battery working from the back seat of my 2005 Prius. Instructions are not perfect, but they never are for auto replacement parts. You need to think for yourself a bit, and have some experience with home auto repair and working with high voltages. Everything works fine; it is like a new battery.

Successful, though a bit tricky for a beginner.
I installed this just a day ago and it was a success! I'll say right off the bat that the battery is great, but plenty of forum postings already attest to it, so I'm focusing on the negative in this review. Overall, I rate it as excellent. The real main issue I had (and I've seen it mentioned elsewhere) is that the safety interlock wires, which are kept from the original assembly, are too long and stiff to attach properly in this new pack without some SERIOUS persuasion. You have to really bend the wires to get them to fit, and they are very thick and stiff. I believe the seller mentioned on a forum that using a hairdryer or heat gun to soften the wires helps. I didn't bother with this, and mine are pressing hard against the metal casing, making it difficult to reassemble. If were doing it again, I would probably take the time to warm up the wires to easily bend them into place. Other minor issues (not the batteries themselves) were: 1. The instructions were incomplete. They did not tell me how to disassemble my old battery, or which parts to remove and which ones to leave in it. They skip from "Take the battery assembly out of the car" to "Put together the new modules". Luckily, I had read about disassembly of Prius batteries, so I didn't have trouble with it. 2. The packing foam. This stuff is extremely messy. All the new battery modules were just covered with little specks of this crap. I had to vacuum off all the modules to get the little white fragments off. A bit annoying. Here's to many more miles!

Prius Feels New
I haven’t had time to thoroughly test drive these. That said, the install was straight forward using their guide. I would recommend getting some 1000v rated, single aught electricians gloves (Google Magid) befor start. My Prius runs so smoothly after I installed these. The owner was helpful in answering questions and just talking shop. Go for it!

Signs your hybrid battery is failing.

A hybrid pack rarely dies all at once. One weak module drags the rest down, and the car tells you in a few predictable ways.

  1. 01A warning light and a battery code The red triangle appears with code P0A80, "replace hybrid battery pack".
  2. 02The charge gauge jumps aroundIt swings from full to nearly empty in minutes instead of moving slowly.
  3. 03The engine never restsIt runs at stop lights and low speed, and fuel economy drops by 5 to 10 mpg or more.
  4. 04Weak or jerky accelerationThe electric assist fades on hills and highway merges, or the car shudders when the engine kicks in.

New, rebuilt or used. Know what you are buying.

Many "replacement" hybrid batteries are reconditioned packs or modules pulled from salvage cars. Ours are not.

Full product details

Description

A complete, brand-new hybrid battery for your Toyota Prius (2004 to 2009). Every cell is new NiMH with zero miles. Not refurbished, not rebuilt, and not pulled from a wrecked car.

Built stronger than the original

  • 14 new cylindrical NiMH modules (14.4 V each, 201.6 V total). Your original pack uses 28 small modules, so there are half as many connections to work loose.
  • Numbered and matched. Modules are tested, matched and numbered before they ship, so they go back in the right order and wear evenly.

When to replace your Toyota Prius battery

  • The red triangle warning is on and the car stores code P0A80 (replace hybrid battery pack)
  • The battery gauge swings quickly between full and empty
  • The engine runs far more than it used to and fuel economy drops

Hybrid batteries usually fail one weak module at a time. Once one goes, the rest are close behind, so replacing the whole pack with new cells is the fix that lasts.

Why new instead of rebuilt or used

  • Brand new, zero miles. Rebuilt packs reuse old modules that are already ageing. Used packs come out of wrecked or high-mileage cars. Ours are new cells, so the whole pack starts its life the day you install it.
  • Keep your car's own electronics. You reuse your original battery case, battery computer, fans and wiring junction, parts you know have not been abused, instead of trusting a pack that came out of a junkyard car.
  • No core charge. Keep or recycle your old modules.

What's in the box

  • 14 new cylindrical NiMH modules
  • New high-voltage wiring harness
  • Nickel-plated bus bars, temperature clips, bolts and terminal nuts

Fits

Toyota Prius 2nd generation, 2004 to 2009. Not for the Prius C or plug-in. Not sure? Email info@newpriusbatteries.com with your VIN.

Installation

Most owners or local shops finish the swap in an afternoon with basic hand tools and insulated gloves. You remove the old modules from the case, fit the new ones in order and refit the pack.

Shipping: pick the option that suits you at checkout

  • Free Shipping – duties included, about 30 days on average. Shipping, import duties and fees are all paid. Nothing to pay at the door.
  • Express – $150, about 5 days. Faster delivery. The carrier collects import duties and fees (usually about $100 to $200) when it arrives.

We ship to the 48 contiguous United States. You get a tracking number as soon as your order ships.

Warranty

3 years or 60,000 miles, whichever comes first, is included. Want more cover? Choose the extended warranty above to add 2 more years (5 years total) for $800. Covered against block voltage error codes. Installation, labour and shipping are not included. Warranty claims are handled directly by NewPriusBatteries.com.

Warranty Information

3 years or 60,000 miles, whichever comes first. Optional extended warranty adds 2 more years (5 years total) for $800. Modules are warranted against block voltage error codes. Installation, labour and shipping are not included. Warranty claims are handled by NewPriusBatteries.com.

    Order was shipped promptly, packaging was good so there was no damage during shipping. The kit is pretty easy to install if you're familiar with these packs. I'll be sharing data from road testing on Priuschat.com
