Why pay more at the dealership? At Greentec Auto, we offer affordable, accessible and reliable hybrid battery replacements at up to 50% less than dealership prices without compromising on quality. Get the best value with expert service, mobile installation, and a warranty you can trust.
The cost of shipping to you is included with your purchase. This offer is good for the entire continental United States. Add $200 for shipping to a residential address. Let Greentec Auto make it simple to return your core to us, ask about our reduced return shipping rates.
A refundable “core deposit” of $500.00 will be added to your order at checkout. Once we receive your old battery, we will refund the core deposit back to you minus the cost of return shipping. Cores must be returned within 45 days of purchase. This applies to shipping orders only. In all other circumstances, the core will be picked up at the time of service, no deposit required.
Once your new hybrid battery has arrived, put the core battery back into the same packaging your battery arrived in. As soon as we receive your core battery, we will refund the core deposit back to you. It’s that easy.
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.
