We closely monitor quality metrics to confirm that our batteries are meeting the quality and performance expectations of our customers, and we stand behind all of our batteries with a one year warranty.

Your repair experience is not going to be easy or enjoyable if you receive a part that doesn’t work. To save you the frustration, we ensure that our products are fully tested. We routinely audit the testing procedures of our suppliers, and closely monitor quality metrics to verify that they’re doing it right. If we identify an issue, we implement our own internal testing to prevent faulty products from reaching our shelves. If a part fails to meet our meticulous quality standards, our team will intercept and reject it — so you can buy with confidence. Our batteries carry a one year warranty, while our other parts are backed by a lifetime guarantee.

For a hassle-free repair experience, many of our top-selling replacement parts come with "fix kits." These kits are thoughtfully curated to include all necessary parts, tools, and adhesives for your specific fix. Alternatively, you can visit the product's detailed page where, if available, you'll find a linked repair guide. This guide will provide a comprehensive list of parts and tools required for the job. Trust us to equip you for success with every repair endeavor!
