What Is a Platinum AGM Battery Group Size 24F?
The phrase "platinum AGM battery group size 24F" describes a specific tier and format of automotive battery, and understanding all three parts of that description separately is the key to choosing the right replacement.
Group size 24F is a BCI (Battery Council International) standardized case code that defines the battery's physical dimensions and terminal layout. Any battery labelled "24F", regardless of brand, must conform to the same physical footprint: approximately 10.71β³ long, 6.77β³ wide, and 8.98β³ tall, with the positive terminal on the right.
AGM stands for Absorbed Glass Mat: the sealed, maintenance-free battery chemistry in which the electrolyte is absorbed into fiberglass mat separators rather than sitting as free liquid. AGM batteries don't spill, don't require water top-ups, charge faster than flooded batteries, and handle deeper discharge without damage. They are required for vehicles with start-stop systems.
All platinum-tier Group 24F batteries from Uplus brands deliver the same core specifications:Β 710 CCA, 120-minute reserve capacity, 70Ah, making the term a useful shorthand for the premium AGM Group 24F format.
Exact Dimensions & BCI Standard
The Uplus Platinum AGM Battery BCI Group 24F dimensions are 10.71β³ L Γ 6.77β³ W Γ 8.98β³ H, consistent with the BCI Group 24F standard across all brands. Slight manufacturing tolerances of Β±0.25β³ may exist. Always measure your battery tray clearance before ordering, particularly length.
Full Specifications: CCA, Ah, Reserve Capacity
The platinum AGM tier has become an industry benchmark for Group 24F.
| Specification | Uplus Group 24F AGM | What It Means |
|---|---|---|
| Voltage | 12V | Standard automotive |
| CCA (Cold Cranking Amps) | 710 CCA | Starting power at 0Β°F (-18Β°C) |
| CA (Cranking Amps) | β | Starting power at 32Β°F (0Β°C) |
| Capacity (Ah) | 70 Ah | Energy storage over 20 hrs |
| Reserve Capacity (RC) | 120 min | Runtime at 25A draw |
| Charge voltage | 14.4β15.0V | Use AGM-compatible smart charger |
| Max charge current | 0β21A | Don't exceed; use AGM mode |
| Operating temp. | -22Β°F to 140Β°F | Wider range than flooded |
710 CCA is the sweet spot for Group 24F, enough to start Toyota, Volvo, Suzuki, Subaru, Shelby, Scion, Saab, Rover, Mitsubishi, Mercury. It also provides meaningful margin as CCA naturally declines with battery age, so a 710 CCA battery still cranks reliably even at 80% of rated capacity (568 CCA) several years into its service life.
What Vehicles Use a Group 24F Battery?
The BCI Group 24F battery is one of the most common sizes for modern passenger vehicles, particularly favored by Toyota, Honda, Nissan, and Ford. A 24F battery is used in vehicles that require the same physical size as a Group 24 but with reversed terminal posts. This is common in many vehicles from manufacturers like Acura, Honda, Infiniti, Lexus, Nissan, and Toyota.
Why Platinum AGM Not Flooded?
The automotive industry has shifted decisively toward AGM chemistry for vehicles with significant electronic loads, and the the 24F model range is one such model. Here's why platinum AGM is the right choice for the vehicles that use this group size:
| Feature | Standard Flooded Battery | Platinum AGM Battery |
|---|---|---|
| Maintenance | Periodic water checks needed | None: fully sealed |
| Spill risk | Yes, liquid electrolyte | Zero, absorbed glass mat |
| Start-stop compatible | No, fails rapidly | Yes, designed for it |
| Charge acceptance | Slow | 3Γ faster recharge rate |
| Vibration resistance | Low | 15 times more vibration-resistant. |
| Cycle life | 200β400 cycles | 4 times extra cycle life |
| Lifespan | 3β5 years | 5β7 years |
| Deep discharge recovery | Poor | Excellent |
| High draw accessory support | Limited | Designed for it |
Platinum AGM batteries are ideal for vehicles with start-stop technology or high demand electrical accessories (back-up cameras, heated seats, navigation, plug-in accessories) which put a heavier load on the battery. The Toyota 4Runner, Lexus GX460, and Nissan Armada, and more are all major Group 24F users, are exactly this type of vehicle: large, accessory-heavy, with sophisticated electrical management systems.
If your vehicle came with AGM from the factory, you must replace it with AGM. A vehicle's Battery Management System (BMS) is calibrated to charge an AGM battery. Installing a flooded battery in an AGM-equipped vehicle causes the BMS to chronically overcharge it, destroying the flooded battery in 6β12 months and potentially triggering persistent warning lights.
Buying Tips: 5 Things to Check
Confirm "24F" β not just "24"
The "F" is not cosmetic. Group 24 and Group 24F have reversed terminal layouts and different lengths. Verify your vehicle requires Group 24F specifically, not Group 24, Group 24R, or Group 35. Use your owner's manual or the label on the existing battery.
AGM is mandatory if your vehicle shipped with AGM
Check the existing battery label, if it says "AGM," "AGM-type," or "Absorbed Glass Mat," you must replace it with another AGM. If your car's original battery is an AGM type, you must continue using an AGM battery, as your car will not accept a "downgrade" to a flooded battery.
710 CCA meets requirements for virtually all 24F applications
The 710 CCA standard meets or exceeds OEM requirements across all Toyota, Honda, Lexus, and Nissan vehicles using Group 24F.Β
Register the new battery if your vehicle has a BMS
Many 2015+ Toyota, Lexus, and Honda vehicles with advanced charging systems need the BMS recalibrated after battery replacement. This is typically done with a diagnostic scanner at a dealer or shop, it tells the system a new battery has been installed so it charges correctly from day one.
The Uplus Group 24F advantage is direct-to-consumer pricing with US warehouse fulfillment, a clean warranty process, and availability online without requiring an in-store visit to a single retail chain.
For Toyota 4Runner, Tundra, Land Cruiser owners, Lexus RX350/GX460 and other drivers: the Uplus Group 24F provides OEM-matching performance at a competitive price. The sealed AGM construction is particularly relevant for off-road use, where vibration and angle exposure are routine: unlike flooded batteries, the sealed AGM design has no liquid to spill regardless of how the vehicle moves.
