CUSTOMER FEEDBACK

Trusted by Hybrid & EV Owners Nationwide

Found them through internet search. Requested mobile installation. They called back within 2 hours to set up an appointment. Turns out they had a shop near me, which saved me 50% on installation cost. Took about an hour.

Prompt, quick, professional service. So much cheaper than getting another car. I would highly recommend their service to anyone who needs a hybrid battery replacement.

I was so grateful that my friend told me about this company. What I thought was going to be a $8,500.00 repair, as quoted to me by my regular auto shop, turned into a $2,400.00 repair. I will be forever grateful to Greentec EV & Hybrid Batteries. Thank you guys so much. Their customer service was excellent over the phone, and my experience with the technician that came to my home to do the repair was also excellent. I can’t thank you all enough. You really saved me!!

The hybrid battery on my prius started dying and I managed to drove to the shop so I left it with them and told me they’ll finish it by tomorrow at 11am but they done it a lot earlier and faster than I expected. The car was running great again with the purchased of 12 month warranty remanufactured. I’m highly satisfied with the work they’ve done and I recommended them big time.

Two Lithium Conversion Options

Professional Lithium Upgrade with Installation ($2,899)

Our complete lithium upgrade package includes premium lithium-ion cells, professional installation, and full system integration. You’ll experience lighter weight, better heat tolerance, improved regenerative braking, and stronger electric assist compared to the original NiMH setup. This turnkey solution comes with 36 months of warranty coverage and unlimited mileage. Currently on sale from $3,295.

DIY Lithium Conversion Pack ($900)

For skilled mechanics and DIY enthusiasts, our conversion pack provides all the lithium cells and hardware needed to upgrade your Insight yourself. You’ll get the same performance benefits as the professional upgrade but save significantly on installation costs. Includes a 30-day limited warranty on the modules as received.

Why Upgrade to Lithium Technology?

If you’re considering a Honda Insight conversion battery replacement, lithium offers measurable advantages over traditional NiMH chemistry:

Superior Heat Management

Lithium batteries handle hot climates far better than NiMH. If you live in the South or Southwest where summer temperatures regularly exceed 95°F, lithium technology prevents the heat-related degradation that shortens NiMH battery life.

Reduced Weight

Lithium cells weigh significantly less than equivalent NiMH packs. The weight reduction improves handling, acceleration response, and overall efficiency — your Insight will feel more nimble and responsive.

Extended Lifespan

While NiMH batteries typically last 5-8 years, lithium conversions often exceed 10 years with proper care. The longer service life means fewer replacements over the time you own your vehicle.

Improved Performance

Lithium delivers more consistent voltage throughout the discharge cycle, which translates to stronger electric assist at all battery charge levels. You’ll notice better acceleration and smoother hybrid transitions.

Better Regenerative Braking

Lithium accepts charge more efficiently during regenerative braking, capturing more energy that would otherwise be lost as heat. This directly improves your real-world fuel economy.

Compatible with All Honda Insight Generations

Our lithium conversion works with both generations of Honda Insight:

  • First Generation (2000-2006): Complete system upgrade for the original two-seater Insight
  • Second Generation (2010-2014): Drop-in replacement for the five-passenger model

Both the professional upgrade and DIY conversion pack are engineered specifically for Honda Insight hybrid systems, ensuring proper voltage, capacity, and BMS integration.

Professional vs. DIY: Which Is Right for You?

Choose Professional Installation If:

  • You want a complete turnkey solution with no hassle
  • You prefer warranty coverage on both parts and labor
  • You’re not comfortable working with high-voltage systems
  • You want certified technicians to handle calibration and testing
  • You value the peace of mind from 36 months of protection

Choose the DIY Conversion Pack If:

  • You’re an experienced mechanic or electrical engineer
  • You have the proper tools and safety equipment for hybrid work
  • You want to save money by doing the installation yourself
  • You enjoy hands-on automotive projects
  • You understand the risks and responsibilities of self-installation

The DIY pack includes comprehensive instructions, but requires technical knowledge of hybrid systems, battery management, and high-voltage safety protocols.

Installation Process

For the professional upgrade, our mobile installation service brings certified technicians to your location. The conversion takes 4-6 hours depending on your Insight generation and includes:

  1. Complete hybrid system diagnostic
  2. Safe removal of the old NiMH battery pack
  3. Installation of new lithium cells and BMS
  4. System calibration and voltage verification
  5. Road test to confirm proper operation
  6. Recycling of your old battery

DIY installers should budget a full day for the conversion, especially on the first attempt. Proper calibration is critical for safe operation and optimal performance.

Is Lithium Conversion Worth the Investment?

Consider the total cost of ownership. A replacement NiMH battery costs $1,400-$2,100 and lasts 5-8 years. If you plan to keep your Insight for another decade, you might need two NiMH replacements at $2,800-$4,200 total.

The lithium upgrade at $2,899 (professionally installed) typically lasts 10+ years — potentially outlasting your ownership of the vehicle. Over time, the lithium conversion actually costs less per year while delivering superior performance throughout its lifespan.

For DIY installers, the $900 conversion pack offers exceptional value if you have the skills to complete the installation safely.

Safety Considerations for DIY Conversions

High-voltage hybrid systems require respect and proper handling. If you’re attempting the DIY conversion, you must:

  • Use insulated tools rated for high-voltage work
  • Wear appropriate personal protective equipment
  • Disconnect the 12V auxiliary battery before starting
  • Follow proper lockout/tagout procedures
  • Verify zero voltage before touching components
  • Understand battery management system programming
  • Have a multimeter capable of measuring high DC voltage

If you’re not completely confident in your ability to work safely with these systems, choose the professionally installed option instead.

Know Your Hybrid’s Battery Health Without Breaking the Bank

If you notice warning lights on your dashboard, don’t rush to the dealership for an expensive diagnostic report. Many local auto parts stores can scan your vehicle and provide error codes for free—just ask them to run a quick scan with a diagnostic tool.

Above, we’ve listed some of the most common hybrid error codes. Keep in mind that the check engine light must be onfor major issues to be detected. If your vehicle is experiencing hybrid battery failure, dealerships often charge thousands of dollars for a replacement—typically with a limited warranty.

At Greentec Auto, we offer a cost-effective alternative, providing high-quality hybrid battery replacements at a fraction of the price. Plus, we back our batteries with a comprehensive warranty to give you peace of mind.
