The Antigravity Group-24 RE-START Lithium Car Battery is a high-performance lithium battery designed to replace standard Group-24 size batteries.
With its unique RE-START (wireless built-in jump-start) feature, if your battery ever dies, you can restart the vehicle simply by pressing a button on the included key fob. There is no need to open the hood or prepare a jump starter.
It features a high-performance BMS (Battery Management System) to prevent over-discharge, over-charge, extreme temperatures, and short circuits.
Compared to conventional lead-acid batteries, it is up to 70% lighter, improving handling, acceleration, and braking performance.

Before placing an order
〇 Regarding import duties
At Shafutoya Shopping Site, we cover the import duties incurred during customs clearance, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇 Checking Compatibility
Our entire product database is based on North American vehicle specifications (USDM). Please confirm the installation compatibility for Japanese domestic market (JDM) vehicles before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and model using the tabs on our top page, it does not necessarily guarantee that they will fit Japanese-model vehicles without modifications.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before placing your order.
○ Regarding Delivery
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping 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.
Essentially, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time for delivery. If you are in a hurry, please contact us in advance to check the lead time. Please note that all products are transported by air; none are shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Essentially, all products handled by us are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide structural integrity documents or similar paperwork for these systems. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and any installation or use is at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the products themselves. We will only provide returns, refunds, or replacements for products with shipping damage, defective goods, or items different from what was ordered if you contact us within 7 days of receipt. Please understand that for products sold through us, warranty-related support will be provided "only through us." We do not provide support through other companies or distributors located within Japan.
