The 2020 Toyota Tacoma typically uses a Group Size 24F, 12-volt automotive battery. This is the standard OEM size for most models from that year, with variations possible depending on trim and equipment.
In practice, the battery size is identified by a label on the battery itself and in the owner's manual or dealer parts catalogs. If you’re replacing or upgrading, verify the exact group size on your current battery and match it to a compatible replacement. The battery is located in the engine bay, usually on the passenger side, and is accessible for inspection or replacement.
Battery specifications for the 2020 Tacoma
The following specifications reflect common OEM configurations for the 2020 Tacoma and what you should consider when replacing the battery.
- Group size: 24F
- Battery type: 12-volt lead-acid (standard, non-AGM; aftermarket AGM options exist but confirm compatibility)
- Typical cold-cranking amps (CCA): commonly around 550–650 CCA depending on the exact model/engine; check the battery label for the precise rating

How to verify the exact size for your truck
Use these steps to confirm you’re selecting the correct battery size for your Tacoma:
- Check the battery label in the engine bay for the Group Size (e.g., 24F)
- Consult the owner's manual or the Toyota parts catalog with your VIN to confirm the approved group size
- Compare with the replacement battery’s group size printed on its label before purchase
- Ask a Toyota dealer or trusted auto shop to cross-check with your vehicle’s specifications if you’re unsure
Verifying the exact size ensures proper fit, terminal configuration, and electrical compatibility for the Tacoma’s systems.
Additional notes on replacement and upgrades
Choosing between standard and AGM
Most 2020 Tacomas come with a standard flooded lead-acid battery, but some owners opt for an AGM (absorbed glass mat) replacement for enhanced vibration resistance and longer life. If you choose an AGM option, ensure it remains compatible with the vehicle’s fitment, geometry, and charging system.
Summary
The 2020 Toyota Tacoma is commonly equipped with a Group Size 24F, 12-volt lead-acid battery. While 24F is the typical size, always verify the exact group size on your current battery label or in the official parts catalog for your VIN, especially if you’re replacing or upgrading. Location is in the engine bay on the passenger side, and when in doubt, consult a dealer or professional technician to confirm compatibility.
