The Antigravity Group-26 RE-START Lithium UTV/Car Battery is a high-performance lithium battery that serves as a direct replacement for standard Group-26 size batteries.
Featuring our proprietary RE-START (wireless built-in jump-starting) technology, if your battery ever goes dead, you can simply press the button on the included key fob to restart your vehicle. No jump starter or roadside assistance required.
Equipped with an advanced full BMS (Battery Management System), it protects against over-discharge, over-charge, thermal runaway, and short circuits.
Compared to lead-acid batteries, it provides up to 70% weight reduction, contributing to improved handling, acceleration, and braking performance.

Before You Order
〇 About Import Consumption Tax
At Shafutoya, we cover the import consumption tax incurred during the import process, so there are no additional charges beyond the total amount paid at checkout.
〇 Compatibility Verification
Our product database is primarily based on North American (USDM) vehicle specifications. Please verify compatibility with Japanese (JDM) vehicles before placing your order. (If you are unsure if a product fits your vehicle, please feel free to contact us; our support team will be happy to assist you.)
If an order is placed without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if our website's category filters show a product based on your selected year, make, and model, it does not guarantee a direct "bolt-on" fit for Japanese-market vehicles.
All product descriptions are translated using translation software. If you find any confusing phrasing, please contact us before ordering.
○ Regarding Shipping
Shipping costs are paid at checkout. Quotes are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the automatic calculation may occasionally differ significantly from the actual shipping cost; in such cases, we will contact you via email.
All items are generally shipped internationally from our U.S. warehouse. Please allow 7 to 14 days for international delivery. If you are in a hurry, please contact us for a delivery estimate in advance. Note that all items are shipped via air freight; we do not use sea freight.
○ Regarding Japanese Road Legal Status (Shaken)
Our products are designed and manufactured outside of Japan and are not compliant with Japanese "Shaken" inspection standards. We cannot provide structural strength documentation or certificates for Japanese inspections. Therefore, all parts are sold for "track, private property, or off-road use only." Installation and use are at your own risk.
○ Regarding Warranty
Please inspect your items immediately upon arrival. As all products are shipped internationally, packaging or items may occasionally sustain transit damage. We will accept returns, refunds, or replacements only if you contact us within 7 days of receipt regarding shipping damage, defects, or incorrect items. Please note that warranty support for products purchased through us must be handled exclusively through us; we cannot offer support via other third-party companies or domestic Japanese agencies.
