Antigravity Batteries H6 / Group-48 RE-START Lithium Car Battery (Wireless Emergency Restart / Full BMS)
The Antigravity H6 / Group-48 is a lithium automotive battery that is fully compatible with standard H6 / Group-48 batteries. With its built-in RE-START (wireless jump-start) feature, you can restart the engine at the press of a button on the included remote control if the battery dies. It also features Full BMS (over-discharge/over-charge/short-circuit/overheat/cell balancing protection) to maximize safety and durability.
Compared to standard lead-acid batteries, it provides a weight reduction of up to 70% (approx. 16–25kg), improving vehicle characteristics such as acceleration, braking, and handling. This is a high-performance battery ideal for both race and street vehicles.

Before Ordering
〇 About Import Taxes
At Shafto-ya Shopping, we cover the import consumption taxes incurred upon arrival, so there are no additional charges beyond the total amount paid at checkout.
〇 Checking Compatibility
All product databases are based on North American (USDM) vehicles. Please verify compatibility with Japanese (JDM) vehicles before ordering. (If you are unsure if the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to investigate for you.)
Returns due to incompatibility are not accepted if ordered without prior confirmation.
Please note that even if items are sorted by selecting the year, make, and model in the tabs on our homepage, it does not guarantee a perfect fit for Japanese-model vehicles without modification.
All products have been translated into Japanese using translation software. Please contact us before ordering if you have any questions regarding confusing phrasing.
○ About Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically by entering your delivery address on the checkout page. For large items such as body parts, the actual shipping cost may differ significantly from the automated calculation; in such cases, we will contact you individually via email.
Generally, all products are shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international delivery takes approximately 7 to 14 days, so please allow ample time for your order.

○ About Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with "Japanese Vehicle Inspection" standards, and we cannot provide structural review documents for these standards. Therefore, all parts are sold for "use on circuits, private land, or off-road," and installation/use is at your own risk.
○ About Warranty
Please check the contents of your order immediately upon arrival. As all products are shipped internationally from outside Japan, there is a possibility of damage to the shipping box or the product. We will only provide returns, refunds, or replacements for shipping-damaged goods, defective items, or incorrect items if notified within 7 days of receipt. Please be aware that for products sold through our company, all warranty claims must be handled "only through us." We do not provide support through other companies or distributors within Japan.
