The Antigravity ATX30 RE-START Lithium Battery is an ultra-lightweight, high-output lithium battery that can replace standard YTX30-size lead-acid batteries. Its most notable feature is the built-in RE-START function, which automatically enters protection mode when the battery is about to die, reserving power for a "restart." Simply press the button on top of the battery to crank the engine and restart your vehicle.
Weighing only approx. 2.6kg, it offers significant weight savings compared to lead-acid batteries of the same size.
Furthermore, it features a powerful 880 cranking amps, making it ideal for big twins, large displacement vehicles, and high-performance custom builds.
It comes equipped with an internal full BMS (Battery Management System) that manages over-discharge, over-charge, thermal protection, and cell balancing to significantly improve safety, longevity, and stability.
The terminals feature a 4-terminal design, allowing for flexible wiring layout on the vehicle.

Before Ordering
〇 About Import Consumption Tax
At Shaft-ya Shopping Site, we cover the import consumption tax incurred during customs clearance, so there will be no additional charges beyond the total amount paid at checkout.
〇 Confirming Compatibility
Our entire product database is based on North American vehicle specifications (USDM). Please confirm compatibility with your Japanese domestic market (JDM) vehicle before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to assist you.)
We cannot accept returns due to incompatibility if an order is placed without prior compatibility confirmation.
Please note that even if items are filtered by year, make, and model using the tabs on our top page, this does not guarantee a direct fitment without modification for Japanese-market vehicles.
All product descriptions are translated into Japanese using translation software. Due to potential confusing phrasing, please contact us if you have any questions before ordering.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automated calculation. In such cases, we will contact you individually by email.
Generally, all items are shipped internationally from our warehouse in the United States. Unlike domestic Japanese shipping, international delivery takes approximately 7 to 14 days, so please order with sufficient time. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all items are shipped via air freight. We do not use sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with "Japanese vehicle inspection standards," and we cannot provide documents such as structural strength certificates for Japanese vehicle inspections. Therefore, all parts are sold for "circuit, private property, or off-road use only," and any installation or use is at your own risk.
○ Regarding Warranty
Please check the contents of your order immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility of damage to the packaging or the product during transit. We will provide returns, refunds, or exchanges only if you contact us within 7 days of receipt regarding items damaged in transit, defective products, or items different from what was ordered. Please understand that for products sold through us, warranty support is handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
