CLEAR ANSWERS

Good to know.

The most important details about your coverage.

What does the manufacturer’s warranty cover?

Covered product and functional defects are assessed and handled in accordance with the warranty terms. Normal wear, age-related capacity loss, and damage caused by improper use, installation, or unauthorized modifications are not covered.

Does a 10-year warranty always mean a free replacement?

No. The remedy provided and any associated costs depend on the specific warranty claim and the applicable warranty terms. We’ll review the next steps with you before proceeding.

Can I try my battery for 30 days?

The 30-day return option is not an unrestricted trial period. Voluntary returns are subject to requirements regarding product condition, packaging, accessories, and other factors. Please review the return policy before installation or use.

Who pays the shipping costs?

Responsibility for shipping costs depends on the reason for the return and the applicable terms. Our support team will confirm whether a prepaid return label will be provided. Please do not return your battery until you’ve contacted us.

What does lifetime technical support mean?

Our team will continue to assist with technical questions about your Lithink battery after the manufacturer’s warranty expires. This does not mean that repairs, replacement parts, or replacement products will always be free.

How do I register my battery?

Use the product registration page on our website and have your purchase and product details ready. Our support team can answer questions about registration and the warranty that applies to your purchase.
