The car still moves. Reduced power, a kind of limp, you drove it home — now you are googling the bill. P0A80 is a scan result, not a purchase order. Public 2026 ranges are below. This is not a shop quote.
If you have not scanned yet, start on symptoms. The numbers on this page assume the hybrid pack is actually the problem.
If the dash is dark and the car will not even wake up, that is often the small 12-volt, not the traction pack. KBB-style roundups mix those two bills into one scary number. Different part, different check.
Usually cheap
A normal auxiliary battery under the hatch (Gen 2/3) or in the engine bay on some later cars. It boots the computers. If the dash is dark, the car is silent, or it acts like a regular dead car, start here.
Ballpark: often around $80, sometimes more for AGM. We do not have a sourced 2026 national average.
The expensive one
The orange-cabled hybrid battery that moves the car. The usual picture: red triangle, P0A80, reduced power, a kind of limp — a car that still moves. Many people drive it home.
Public 2026 ranges: about $950 shipped recon up through $3,500–$5,000+ at a dealer. Diagnose before you buy.
A conventional 12-volt auxiliary battery is a normal parts-store purchase — often around $80, sometimes more for AGM. We do not have a sourced 2026 national average, so treat that as a ballpark, not a quote.
If the red triangle is on, P0A80, reduced power, a kind of limp — and the car still moves — read the glove-box warranty booklet before you treat the numbers below as your bill. Factory HV coverage is 8 years / 100,000 miles on 2019 and earlier, 10 years / 150,000 miles on 2020 and newer (Toyota’s 2020 announcement). Some states already had 10 / 150 on earlier cars under emissions rules. Check the glove-box warranty booklet for the car in front of you.
Still in coverage: stop shopping vendor prices. Go to the dealer first. Aftermarket packs do not preserve remaining Toyota HV coverage. Out of coverage: then the public ranges below apply — and only after a real diagnosis on symptoms, not a dark-dash 12-volt scare.
These are public figures as of 30 August 2026. They are not invoices, and they are not “we priced 17 shops.” Taxes, core charges, shipping, and local labor sit on top.

Public Gen 2 / Gen 3 reman about ~$1,399 with 24 months; new cells about ~$2,099 with 48 months. This guide has not tested their packs.
NexPower reseller with mobile install. Useful if you want sodium modules and do not want to open an HV case. This guide does not have a sourced 2026 installed-price sheet from them, so it will not invent one.
Public recon pricing for a complete Gen 2 / Gen 3 pack (~$950). Comparison column — this guide has not used them.
Come-to-you reman / new / sodium. $1,349–$1,949 installed on most Prius work, per their own 2026 blog. Core charges if you do not return the old pack. Mixed PriusChat and BBB warranty reputation — see OEM vs reman vs sodium.
| Path | Typical $ range | Who it is for | Warranty shape | DIY vs mobile |
|---|---|---|---|---|
| Diagnosis first | Dr. Prius (free + IAP tests) + Veepeak BLE ~$32; 12V often ~$80 | Anyone whose dash just lit up or whose car went silent | n/a — this is not a pack | You + Dr. Prius / Veepeak, or a shop scan |
| DIY sodium modules | $1,350–$1,890 parts (Salty / NexPower list) | Handy owners who accept HV risk and a shorter DIY warranty | NexPower since Mar 2023: 2 years unlimited miles with a certified installer, 1 year DIY, non-transferable | DIY (or NexPower-certified installer) |
| Shipped reman pack | ~$950 (Hybrid CPR) to ~$1,399 (Greentec reman) | Price-sensitive owners who will install locally or themselves | Greentec reman: 24 months. Hybrid CPR: see their pricing page. | Ship + DIY or local install |

| Toyota dealer | $3,500–$5,000+ (Green Bean’s cited dealer range); RepairPal $4,501–$4,694 | Still in factory warranty, or you want OEM paper and will pay for it | Factory HV warranty if still covered; otherwise whatever the dealer writes on the invoice | Dealer |
These ranges skip a made-up used-Prius trade-in so the math looks tidy, and they skip Dorman HV packs — out of stock, poor reviews.
I tried balancing a pack. Limited success. A Prius sodium-ion and a Camry have been in use here for about two years with no issues — owner experience, not a product guarantee. Sodium is still not Toyota OEM.
If you are deciding whether the car itself is still worth the bill, use the 150k / 200k page.

They are mixing a silent 12-volt with the hybrid pack that still moves the car. KBB-style roundups do this. A dark dash is often about $80. A traction pack is four figures.
Hybrid CPR’s public pricing page lists a complete recon Gen 2 / Gen 3 pack around $950. That is parts, not a nationwide mobile install, and we have not used them.
