Lightweight Jaguar Battery – Antigravity H7 / Group 94R Lithium

Description

Lightweight Jaguar Battery – Antigravity H7 Lithium

A lightweight Jaguar battery is one of the simplest ways to remove meaningful weight from a performance build without increasing engine or drivetrain stress. The Antigravity H7 / Group 94R lithium battery combines high cranking power with LiFePO4 construction, a built-in Battery Management System and wireless RE-START emergency starting.

Compared with a conventional lead-acid or AGM battery, the correct Antigravity configuration can reduce vehicle weight by up to approximately 45 lb, depending on the battery being replaced and the capacity selected.

Lightweight Battery Upgrade for Jaguar Performance Models

This battery is intended for compatible H7 / Group 94R-equipped Jaguar applications, including models such as the Jaguar F-Type, XK / XKR, XE, XF / XFR, XJ / XJR and F-Pace. It is also suitable for selected H7 / Group 94R-equipped Range Rover and Range Rover Sport applications.

That makes it relevant for customers searching for a Jaguar F-Type lightweight battery, Jaguar XK lightweight battery, Jaguar XKR lightweight battery, Jaguar XE lightweight battery, Jaguar XF lightweight battery, Jaguar XJ lithium battery or Jaguar F-Pace lightweight battery.

These are the same types of Jaguar and Range Rover performance platforms commonly upgraded with Alpha Jag ECU tuning, supercharger pulleys, performance intakes, cooling upgrades and lightweight brake components. Reducing battery mass complements those modifications by removing weight rather than adding additional engine load.

Why Reduce Battery Weight?

Battery weight is carried by the vehicle at all times. Replacing a heavy conventional battery with a lithium starter battery can reduce total vehicle mass without changing engine calibration, boost pressure or drivetrain loading.

A reduction of up to approximately 45 lb is significant for a single bolt-in component. Lower vehicle mass benefits acceleration, braking and directional response, while the Antigravity H7 platform still provides high cranking output for starting a performance engine.

Wireless RE-START Technology

Antigravity’s RE-START system is designed to retain reserve energy if the battery reaches its low-voltage protection threshold. The reserve can be activated using the supplied wireless key fob or manually at the battery, allowing the vehicle to be restarted in supported discharge situations without a separate jump pack.

Built-In Battery Management System

The integrated BMS provides protection against over-discharge, over-charge, short circuit and excessive temperature, along with cell balancing. This helps keep the LiFePO4 cells within their intended operating range while maintaining strong cranking performance.

Choose Your Lightweight Jaguar Battery Capacity

• 40Ah / 1500 CA / 14.75 lb – greatest weight reduction and strong cranking output.
• 60Ah / 1800 CA / 20.75 lb – additional reserve capacity while remaining substantially lighter than many conventional batteries.
• 80Ah / approximately 2000 CA / 25.5 lb – highest capacity and cranking output in the H7 range.

Recommended Performance Pairings

For a more complete performance build, pair the lightweight battery with Alpha Jag Custom ECU Tuning and Jaguar Lightweight Two-Piece Performance Brake Rotors. These upgrades complement the battery by improving power delivery and reducing additional vehicle or rotating mass.

H7 / Group 94R Battery Size & Specifications

All three versions use the same standard H7 / Group 94R case:

• Battery group: H7 / Group 94R
• Case dimensions: 12.25 x 7 x 7.5 in (312 x 175 x 190 mm)
• Nominal voltage: 12.8V
• Chemistry: LiFePO4 lithium iron phosphate
• Terminals: M8 x 1.25 threaded terminals
• Capacity options: 40Ah, 60Ah, 80Ah
• Cranking output: 1500 CA, 1800 CA or approximately 2000 CA

Fitment – Verify H7 / Group 94R Before Ordering

Battery size is not determined by model name alone. Jaguar and Land Rover battery specifications can vary by year, engine, market and equipment level. Some vehicles may use H6 / Group 48 or H8 / Group 49 rather than H7 / Group 94R.

This product is specifically the H7 / Group 94R Antigravity battery. Verify the group size printed on the existing battery, check the battery tray and terminal orientation, or contact Alpha Jag with the year, model and current battery information before ordering.

This is particularly important for XK / XKR applications because battery size can vary by model year and configuration. The lightweight-battery search terms above describe compatible performance applications, not a guarantee that every model year uses H7 / Group 94R.

Charging & Shipping

Use an external charger specifically compatible with LiFePO4 lithium automotive batteries. Do not use incompatible lead-acid desulfation or reconditioning modes. Adult signature is required for shipment, and Antigravity currently states that the 80Ah version cannot be shipped by air.
