Replace, refurbish, or sell your EV battery?
A dead traction battery feels like the end of the car. It usually isn't. Here's the simple framework that decides it, the same one every estimator on this site runs for you.
The whole decision comes down to one comparison: the cheapest fix that genuinely works, against what the car is worth with a healthy battery. Everything else is detail. Once you have those two numbers side by side, the right move is usually obvious, and it falls into one of three buckets.
Replace it
When the car is worth clearly more than a fresh pack, replace the battery and move on. This is the easy case, and it's where most Teslas and newer EVs land: a car worth $25,000 with a $12,000 pack is a car you fix. The only real choice left is who does the work. A dealer will quote the most; an independent EV shop fitting the same new pack almost always beats it on labor. Get both numbers before you sign.
Refurbish it
When the car is worth keeping but a brand-new pack is overkill, a refurbished or reconditioned battery is the value play. This is the sweet spot for hybrids. A clean Prius or Camry hybrid with a $2,000 refurbished pack keeps returning 50 mpg for years, at a fraction of a replacement car's cost. A refurbished pack won't last as long as new, but on a car you'd otherwise keep, the math is hard to beat. Just buy from a rebuilder who tests cells and warranties the pack.
Sell it
When even the cheapest real fix costs about as much as the car is worth, stop. This is the trap the site was built to spot: the $3,000 battery on a $3,000 car, or the $16,000 Bolt pack on a car worth not much more. An old Nissan Leaf is the textbook example, where a new pack can cost more than the car. In these cases, selling as-is or parting the car out almost always beats pouring money into it. A non-running EV still has real salvage value, and there are buyers who specifically want them.
Two things people get wrong
First, they take the dealer's quote as the only number. There are almost always cheaper paths, from an independent shop to a refurbished pack to a module-level recondition, and a dealer has no reason to mention them. Second, they value the car as if the battery were fine. It isn't. A dead-battery EV or hybrid is worth far less than a healthy one, and that lower as-is value is the number that decides everything.
Just run your numbers
Every model page here has an estimator that does exactly this. You pick the pack and the path, tell it what the car's worth, and it returns a cost range plus a straight replace-refurbish-or-sell call.

Replace, refurbish, or sell: common questions
When is it not worth replacing an EV or hybrid battery?
When the cheapest realistic fix costs about as much as the car is worth, or more. A $16,000 pack on a used car worth $14,000 rarely makes sense, and neither does a $3,000 battery on a $3,000 car. The rule of thumb: if even a refurbished or reconditioned pack costs more than roughly half the car's value, selling or parting it out deserves a serious look.
Is a refurbished battery better than buying a new car?
Often, yes, when the car is otherwise sound. A refurbished hybrid pack for $1,500 to $2,800 keeps a reliable car on the road for years at a fraction of the cost, taxes, and depreciation of a replacement vehicle. The math weakens when the car has other major problems stacking up, or when the battery is a large EV pack that costs as much as a used replacement car on its own.
How do I find out what my car is worth before deciding?
Get a quick private-party or trade-in value from a major valuation site, then knock it down for the dead battery, since a non-running EV or hybrid is worth far less than a healthy one. That lower 'as-is' number is the one that matters. Our model estimators ask for the car's value precisely because the whole decision turns on it.
