Antigravity SC-2 Super-Charger (2-Amp Smart Battery Charger / Maintainer)
The Antigravity SC-2 Super-Charger is a multifunctional smart charger compatible with automotive, motorcycle, and powersports batteries. It supports both LiFePO4 lithium batteries and lead-acid batteries, and is capable of handling both 6V and 12V voltages.
Designed as a single charger capable of managing and charging various batteries, it handles everything from daily maintenance charging to maintaining voltage during long-term storage (maintenance mode).
The SC-2 is a 2-amp model, ideal for 3Ah to 60Ah batteries. If you need to charge large-capacity batteries quickly, the higher-end models SC-4 / SC-10 are recommended.

Before Ordering
〇 Regarding Import Taxes
At Shaft-ya Shopping, we pay the import consumption taxes incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇 Checking Compatibility
All product databases are based on North American vehicles (USDM). Please confirm whether the item can be installed on a Japanese vehicle (JDM) before placing your order. (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 assist you.)
If an order is placed without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, make, and model in the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
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 ordering.
○ Regarding Shipping
Shipping costs are paid at the time of settlement. Shipping estimates are calculated automatically when 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 via email.
In principle, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international shipping takes approximately 7 to 14 days, so please allow ample time for delivery. If you are in a rush, please inquire about delivery times in advance. All items are shipped via air freight; we do not ship via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products handled by us are designed and manufactured outside of Japan. They are not compliant with "Japanese Vehicle Inspection Standards," and we cannot provide strength calculation reports for Japanese inspections. Therefore, all parts are sold for the purpose of "circuit, private property, or off-road use," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon delivery. As all products are shipped internationally from outside Japan, packaging boxes or the products themselves may sustain shipping damage. We will only provide returns, refunds, or replacement products if we are notified within 7 days of receipt for items that have shipping damage, are defective, or are different from what was ordered. Please understand that for products sold through us, warranty support will be handled "only through us." We do not provide support through other companies or agencies based in Japan.
