Frequently Asked Questions
What is the AG-H7-80-RS?It is an Antigravity H7/Group 94R 12.8V LiFePO4 automotive starting battery with 80Ah capacity, approximately 2,000 cranking amps, a full BMS, and wireless RE-START technology.
Will this battery fit my vehicle?It fits only when the H7/Group 94R case, 12.25 × 7 × 7.5 in (312 × 175 × 190 mm) dimensions, terminal orientation, hold-down, cable reach, electrical demand, and charging system match your application.
How does wireless RE-START work?If the BMS detects over-discharge, it can place the battery into sleep mode while reserving enough energy for an emergency start. Use the supplied key fob or the button on the battery to reactivate it.
Can I use a standard lead-acid charger?Use only a charger approved for 12V LiFePO4 batteries. Do not use unsupported desulfation, repair, or lead-acid-only charging modes.
Does this replace an AGM battery?It can replace a compatible lead-acid or AGM battery when the physical fitment, capacity, charging voltage, parasitic draw, and manufacturer requirements are all suitable.
Is a battery tray modification required?No tray modification is normally required when the vehicle uses the matching OEM H7/Group 94R case and hold-down arrangement, but the installation must be measured and verified.
Is the battery safe for a street vehicle?The integrated BMS provides multiple layers of protection, but correct installation, charging compatibility, secure mounting, and compliance with the vehicle manufacturer’s requirements remain essential.
Are there shipping restrictions?An adult signature is required for delivery. The 80Ah model cannot ship by air.
Installation Instructions
- Confirm H7/Group 94R fitment, polarity, cable reach, hold-down style, charging voltage, and vehicle battery requirements.
- Turn the vehicle off and disconnect the existing battery according to the vehicle service manual.
- Install AG-H7-80-RS in the correct orientation and secure it with the factory-compatible hold-down.
- Connect the positive and negative cables to the correct terminals and tighten them to the manufacturer’s specification.
- Verify charging-system voltage, check for abnormal parasitic draw, and test the RE-START remote before returning the vehicle to service.
