FAQ
1. How do I determine what specifications of product I need?
First, confirm the engine displacement of your or your main customer group's vehicles. Generally, higher displacement vehicles require a larger starting current, and battery capacity is positively correlated with starting current. Also, note that lithium batteries experience reduced activity in cold environments; therefore, in cold regions, even for small-displacement vehicles, it's best to use a larger capacity starting power supply.
2. Why do some manufacturers offer significantly larger battery capacities and starting currents for the same product size?
You need to know that current global battery technology still prioritizes energy density in relation to battery volume and weight. If the product you receive has an abnormally high peak current or capacity, be aware that it may be fraudulent. We are committed to providing genuine and high-quality products to our customers; this is our bottom line.
3. What kind of after-sales policy do we offer?
We offer two different after-sales policies to suit your needs: 1. We provide a certain percentage of extra products with each order for you to replace your customers' products; 2. We offer a 1-2 year after-sales guarantee. During this period, you need to collect the damaged products and send them back to the factory for our technicians to assess. If the damage is not caused by human error, we will resend the products with your next order.
4. What can I customize for the products?
We offer rich and flexible customization services. For standard product versions, you can choose battery capacity, product color, logo printing, customized outer packaging, cable clip specifications, customized product specification labels, and instruction manuals. If you need a more competitive product, you can choose a full ODM service. We provide free appearance design and 3D modeling. You only need to pay an additional mold fee to have your own custom molded product.
5. What certifications do our products support?
Our products can support almost any certification you need, such as: CE, FCC, 3C, UKCA, UL, PSE, BIS, RoHS, UN38.3, MSDS, TÜV, etc.
