The 2004 Lexus GX470 uses a standard 12-volt automotive battery. In most cases, the correct replacement is a Group 24F (often labeled 24F) flooded lead-acid battery with about 700–750 cold-cranking amps (CCA) and roughly 70–75 amp-hours (Ah). Always verify the exact size and specs on your current battery label or in the owner's manual.
Beyond the basics, the GX470’s electrical system relies on a conventional lead-acid battery rather than a hybrid or specialized unit. Replacement choices typically fall into a few group sizes and formats, with options ranging from plain flooded batteries to high-performance AGM (absorbent glass mat) variants. Climate, driving habits, and equipment loads all influence the best pick.
Battery basics for the 2004 GX470
The GX470's electrical design is compatible with standard automotive batteries. While many owners stick with the OEM-recommended group size, aftermarket options are common as long as they fit the battery tray and meet minimum CCA and Ah requirements. If you routinely drive in very cold conditions or use many accessories, you may opt for a battery with higher CCA and reserve capacity.
Common group sizes and specs
The following sizes are commonly used for replacements in the 2004 GX470. Check the label on your current battery or your vehicle’s manual to confirm the exact requirement for your vehicle, as regional variations can apply.
Battery type options
Most GX470s use a traditional flooded lead-acid battery, but AGM options are widely available. AGM batteries can offer longer life and better performance in some climates, though they may require a compatible charger and can be more expensive.
- Group Size 24F: 12V flooded lead-acid or AGM option; typical 70–75 Ah; 650–750 CCA; reserve capacity around 100–120 minutes.
- Group Size 24: Similar specs to 24F, with minor variations in terminal layout depending on the manufacturer.
- AGM options: Readily available from major brands; often higher CCA and longer life, but ensure proper fit and compatibility with the vehicle’s charging system.
Conclusion: When replacing, choose a battery that matches or exceeds OEM electrical requirements, ensures proper fit in the tray and with the terminals, and take climate into account for CCA and reserve capacity. Always verify the exact group size from the battery label or service manual.
OEM guidance and installation tips
To guarantee compatibility, confirm the replacement with your vehicle’s VIN at a dealer or trusted parts retailer. If you’re shopping aftermarket, look for a battery labeled Group 24F (or 24) with CCA in the 650–750 range and at least 70 Ah. Ensure the battery terminals match your vehicle’s configuration and that the new battery fits securely in the tray and clamps.
Summary
For a 2004 GX470, the typical battery choice is a 12-volt Group 24F (or sometimes 24) flooded lead-acid battery with about 700–750 CCA and roughly 70–75 Ah. AGM variants are an option if you want higher performance, but always verify fitment and charging compatibility. When replacing, consult your owner’s manual or the current battery label to confirm the exact size and specifications, and consider climate and driving habits to select the best CCA and reserve capacity.
