Frequently Asked Questions

What is the AG-H6-40-RS?

It is a H6 / Group 48 lithium starter battery with 40Ah capacity, 1500 cranking amps, BMS protection, and wireless reserve-starting capability.

Will it fit my vehicle?

Fitment depends on case size, tray dimensions, hold-down style, terminal position, polarity, and charging-system compatibility. Compare every specification with the original battery before ordering.

What does RE-START do?

The battery can reserve enough energy for a restart after an over-discharge event. The reserve can be activated with the compatible wireless remote.

Can I use a standard lead-acid charger?

No. Use a charger approved for 12V LiFePO4 starter batteries and follow Antigravitys charging limits.

Does it work with every alternator?

No. Confirm that the vehicle charging system operates within the manufacturers approved lithium-battery voltage range.

Is this a deep-cycle battery?

No. It is designed primarily as a starter battery, not as a dedicated deep-cycle house battery.

Can I install it myself?

Installation is straightforward when the case size and terminals match, but electrical safety and secure mounting are essential. Professional installation is recommended when fitment is uncertain.

How should it be stored?

Disconnect parasitic loads, store it in a dry temperature-controlled location, and check charge condition according to the manufacturers instructions.

Installation Instructions

1. Turn the vehicle off and disconnect the negative cable before the positive cable.
2. Remove the original battery and confirm the tray, hold-down, polarity, and cable reach.
3. Secure the lithium battery so it cannot move or contact surrounding components.
4. Connect the positive cable first, then the negative cable, and verify tight clean connections.
5. Confirm normal charging voltage and test the RE-START remote according to the manufacturers instructions.

Frequently Asked Questions

What is the AG-H6-60-RS?

It is an Antigravity H6/Group 48 12.8V LiFePO4 automotive starting battery with 60Ah capacity, 1,800 cranking amps, a full BMS, and wireless RE-START technology.

Will this battery fit my vehicle?

It fits only when the H6/Group 48 case, 10.75 7 7.5 in (272 175 190 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 H6/Group 48 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 manufacturers requirements remain essential.

Are there shipping restrictions?

An adult signature is required for delivery.

Installation Instructions

1. Confirm H6/Group 48 fitment, polarity, cable reach, hold-down style, charging voltage, and vehicle battery requirements.
2. Turn the vehicle off and disconnect the existing battery according to the vehicle service manual.
3. Install AG-H6-60-RS in the correct orientation and secure it with the factory-compatible hold-down.
4. Connect the positive and negative cables to the correct terminals and tighten them to the manufacturers specification.
