2017 Toyota Tacoma Battery Size & Group

Quick Answer

• BCI Group Size: 24F
• CCA Rating: 700-750 CCA (minimum)
• Reserve Capacity: 120-140 minutes
• AGM vs. Flooded: Either is suitable, but AGM offers benefits.
• Terminal Layout: Top Post, Positive on Right (when viewed from front with terminals closest to you)
• Physical Dimensions: Approximately 10.25" L x 6.8" W x 9" H
• Dual Battery Setup: Not standard for gasoline models.

Replacement Battery Options

• Interstate: Group 24F (e.g., MT-24F, MTZ-24F for AGM)
• Optima: YellowTop D34/78 (requires adapter for proper fit due to slightly smaller dimensions, fits 24F applications)
• DieHard: Platinum AGM Group 24F
• Odyssey: Group 24F (e.g., 24F-750DIN, PC1500DT)
• ACDelco: Professional AGM 24FAGM

AGM vs Flooded — Which Does This Vehicle Need?

For your 2017 Toyota Tacoma, both AGM (Absorbed Glass Mat) and traditional flooded lead-acid batteries are suitable. The vehicle does not require an AGM battery from the factory. However, AGM batteries offer several advantages:

• Durability: More resistant to vibration and impacts, which can be beneficial for off-road enthusiasts or those driving on rough roads.
• Maintenance-Free: No need to check water levels.
• Slower Self-Discharge: Holds a charge longer when the vehicle is not in use.
• Better Performance in Extreme Temperatures: Generally performs better in both very hot and very cold conditions.
• Deep Cycling Capability: Better suited to handle repeated deep discharges, which can occur with aftermarket accessories or frequent short trips.

While AGM batteries typically cost more upfront, their longevity and performance benefits often justify the investment for many Tacoma owners. If you opt for a flooded battery, ensure it's a good quality unit with adequate CCA and RC ratings.

Post-Installation Relearn / Reset Procedure

After disconnecting and replacing the battery in your 2017 Toyota Tacoma, you may notice a few things behaving differently until the vehicle "relearns" certain parameters. Here's a general procedure:

1. Engine Idle Relearn: The engine control unit (ECU) may need to relearn its idle parameters. After connecting the new battery, start the engine and let it idle for 10-15 minutes without touching the accelerator. The idle may be slightly erratic at first but should smooth out.
2. Power Window Reset: Power windows may lose their auto up/down function. To reset:
   • Close the window completely.
   • Hold the window switch in the "up" position for a few seconds after it's closed.
   • Open the window completely.
   • Hold the window switch in the "down" position for a few seconds after it's open.
   • Repeat for all windows.
3. Radio Presets and Clock: You will need to reset your radio presets and the clock manually.
4. Trip Computer/Fuel Economy Data: This data will be reset to zero.
5. Steering Angle Sensor (potentially): While less common on this generation Tacoma, some vehicles may require a steering angle sensor calibration if the VSC (Vehicle Stability Control) light comes on after battery replacement. This typically involves driving straight for a short distance or a specific turn-lock-to-lock procedure.

Always consult your owner's manual for specific instructions for your vehicle model.

Signs of a Failing Battery

Don't wait for a complete battery failure to replace it. Watch out for these common signs:

• Slow Engine Crank: The engine turns over slowly or
