The Antigravity ATX12 RE-START Lithium Battery is an ultra-lightweight, high-performance lithium battery that can replace a standard YTX12-size lead-acid battery. Its most notable feature is the integrated RE-START technology, which enters a protection mode when it detects a low charge, reserving enough power to start the vehicle. You can start the engine simply by pressing the button on the battery itself.
Weighing only about 1.2 kg, it delivers high starting performance with 360 cranking amps. It is suitable for a wide range of uses, from daily commuting and touring to lightweight racing applications. It also features an integrated full BMS (Battery Management System), which manages over-discharge, over-charge, thermal protection, and cell balancing to significantly improve safety and longevity.

Before Ordering
〇 Regarding Import Taxes
At Shaft-ya, we cover the import taxes incurred during customs clearance, so you will not be charged anything beyond the total amount paid at checkout.
〇 Compatibility Verification
Our product database is based on North American vehicles (USDM). Please confirm compatibility with Japanese models (JDM) before placing your order. (If you are unsure whether a listed product fits your vehicle, please feel free to contact us, and our support team will investigate for you.)
If an order is placed without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model on our homepage, it does not guarantee a direct fit for Japanese-spec vehicles without modification.
All product descriptions have been translated into Japanese using translation software. As there may be ambiguous expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically upon entering your address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual cost. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international delivery takes approximately 7 to 14 days, so please allow sufficient time for your order. If you are in a hurry, please contact us in advance to confirm the delivery schedule. All products are shipped via air freight; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan and are not compliant with "Japanese vehicle inspection" (Shaken) standards. Furthermore, we cannot provide strength calculation documents or similar paperwork for these requirements. Therefore, all parts are sold for "circuit, private property, and off-road use only," and their installation and use are at the customer's own risk.
○ Regarding Warranty
Please check your items immediately upon arrival. Since all products are shipped internationally, there is a possibility of damage to the packaging or the product itself during transit. We will only accept returns, refunds, or exchanges if we are notified within 7 days of receipt regarding damaged, defective, or incorrect items. Please note that for products sold through us, all warranty support must be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
