Farmers Branch sits where two of the busiest freeways in North Texas meet: I-635 (LBJ Freeway) along the south side and I-35E (Stemmons Freeway) through the west. Plenty of residents drive one or both every day, and others take DART from the Farmers Branch Station. Whether you live near Farmers Branch Historical Park or closer to the freeways, if you drive an older Toyota Prius with 150,000+ miles, you probably want to keep a car that has been reliable for years rather than replace it.
DFW Hybrid Battery provides mobile hybrid battery diagnostics, repair and rebuilds in Farmers Branch; on-site diagnostics are $150 and 100% credited toward the repair, since Farmers Branch is part of our regular service area. Most jobs are done at your home or work; when a repair needs it, we can bring the car to our shop.
Older Prius Ownership: What Wears Out and What It Costs
The original battery in a 2004–2015 Prius has done a lot of work by now. Stop-and-go freeway traffic means the pack charges and discharges constantly, and after many years some modules lose capacity faster than others. Once the gap between the strongest and weakest modules grows too large, the car sets a fault and turns on the warning lights.
Second-generation Prius (2004–2009)
These packs are now well past their factory warranty. A full rebuild with tested, matched reconditioned modules is $1,300 — see our Prius Gen 2 page for details.
Third-generation Prius (2010–2015)
A popular commuter car. A full rebuild is $1,400; more on the Prius Gen 3 page.
Repair or retire the car?
If the body, engine and transmission are healthy, a rebuild often makes more sense than a car payment. We test first and tell you honestly if the numbers don’t add up.
A clogged battery cooling fan is another common issue on older cars. Dust and pet hair block the intake near the rear seat, the pack runs hot in traffic, and the battery ages faster. Keeping that intake clean is one of the cheapest ways to protect it.
Warning Signs Commuters Report Most
- The engine runs much more than it used to, and the battery gauge swings from full to empty quickly
- A “Check Hybrid System” message with P0A80 stored
- P3000 battery control codes or battery temperature and cooling codes
- Fuel economy dropping a few MPG at a time over several months

What Happens When You Call
1. Quick phone check
We ask about the car, the mileage and what the dash shows, then set a time at your home or workplace.
2. On-site battery test
We read codes and measure every block of the pack, then check the cooling fan and intake. See how our diagnostics work.
3. Straight answers on cost
You get the test results and the options in writing — module repair, full rebuild or replacement — before any work starts.
4. Back on the freeway
After the repair we clear codes and road-test the car while watching live battery data.
Prices
Diagnostics are $150 and fully credited toward the repair. Module repair starts from $700 labor + parts; full rebuilds start at $1,300 depending on the model, and replacement is quoted by phone. All prices are on our hybrid battery cost page. A car that has sat for a long time may only need a hybrid battery charge, from $300.

Buying a Used Hybrid in Farmers Branch? A Passed Inspection Is Not a Battery Test
Since January 1, 2025, non-commercial vehicles in Texas no longer need a safety inspection before registration. Dallas County, which includes Farmers Branch, is one of the counties that still requires an emissions test. Neither one measures the health of each module in a hybrid battery pack. A used hybrid can register and drive fine on a test drive and still have a pack that is close to setting a warning light.
If you are shopping for a used Prius, Camry Hybrid, Sonata Hybrid or Lexus hybrid, a pre-purchase battery check takes the guesswork out. We can test the car at the seller’s location, and you get the same written Battery Health Report, with the voltage of every module, that our repair customers get.
Ask about the battery’s history
Has the hybrid battery ever been repaired, rebuilt or replaced? Ask for the paperwork and any warranty that came with the work.
Look at the battery cooling intake
On many hybrids it is near the rear seat. A vent packed with dust or pet hair means the pack may have been running hot.
Check the factory battery warranty
Toyota covers the hybrid battery for 10 years / 150,000 miles on 2020 and newer models and 8 years / 100,000 miles on 2019 and older. On 2012–2019 Hyundai Sonata Hybrids, lifetime coverage is for the original owner only; later owners get 10 years / 100,000 miles. A dealer can check the VIN.
Watch for codes, not just lights
A seller can clear a warning light. A scan of the hybrid and battery modules shows codes such as P0A80 and the data behind them.
Hybrid Battery Replacement in Farmers Branch, TX
Farmers Branch is in our regular service area: the on-site diagnostic is $150 and 100% credited toward the repair. That test tells you whether you need a replacement or something smaller.
When is replacement the right call? When the pack is physically damaged (water, swelling, heavy corrosion), when nearly every module is worn and you are keeping the car for years, or when the battery design is not practical to repair module by module. In many other cases, module repair from $700 labor + parts, or a full rebuild with tested, matched reconditioned modules, is the better value.
| Option | How it compares |
|---|---|
| Full rebuild with reconditioned modules | Fixed prices by model, $1,300–$2,400; see the cost page |
| New pack | Highest price, longest expected life; call for a quote |
| Remanufactured or tested-used pack | Lower cost than new; call for a quote |
The final price depends on the vehicle, the pack type and the option you pick. A full replacement often costs $1,500–$4,000 at other shops, and more at a dealer. Every job includes a written warranty of 1 to 3 years, depending on the car’s condition and mileage, before work starts. Learn more about hybrid battery replacement.
