2017 Toyota Highlander — Battery Size & Group (Specs, CCA, RC)

Quick answer

• BCI group size: 24F (reverse terminal layout)
• Cold Cranking Amps (CCA): minimum 550 CCA; 650–750 CCA recommended for colder climates
• Reserve Capacity (RC): ~120–140 minutes (minimum 110 minutes)
• Chemistry: Flooded lead-acid acceptable on gasoline models; AGM optional/upgrade. Hybrid models use an AGM auxiliary 12V.
• Terminals/layout: SAE top posts; positive on the left (when posts are closest to you)
• Physical dimensions (Group 24F): ~10.3" L × 6.8" W × 9.0" H (260 × 173 × 229 mm)
• Dual-battery setup: Not applicable (no diesel option on 2017 Highlander)

Replacement battery options

These are common, high-quality replacements that fit Group 24F. Verify CCA/RC options at purchase.

• Interstate MT-24F (flooded) — strong OEM-style choice; multiple CCA tiers available
• Interstate MTX-24F (AGM) — AGM upgrade for higher accessory load and durability
• DieHard Gold 24F — reliable flooded battery with solid RC for daily use
• DieHard Platinum AGM 24F — premium AGM for extreme temps and heavy electrical demand
• ACDelco Gold 24F — OE-style flooded replacement with competitive warranty
• Odyssey Performance 24F (AGM) — deep-cycle capable AGM with high reserve capacity

AGM vs flooded — which does this vehicle need?

• Gasoline 2017 Highlander: A high-quality flooded Group 24F meets factory requirements. Toyota did not require AGM for the gas models located in the engine bay. If you tow, idle with accessories on (rear entertainment, heated seats, etc.), or drive in very hot/cold climates, an AGM 24F is a worthwhile upgrade thanks to better vibration resistance, slower sulfation, and stronger recovery from deep discharges.
• Hybrid 2017 Highlander: Uses a 12V auxiliary battery that should be AGM due to its interior/cargo-area location and venting requirements. Always match what’s on the vehicle label.

Post-installation relearn / reset procedure

Using a memory saver during the swap avoids most resets. If the battery is fully disconnected, plan to:

1. Idle/ECM relearn
   • Start the engine with all accessories off. Let it idle for 3–5 minutes, then turn A/C on and idle another 3–5 minutes. Drive normally, allowing a few decel-to-idle events. The ECM will relearn fuel trims and idle control.
2. Power window initialization (auto up/down)
   • For each window: key ON, lower window fully and hold the switch down 1–2 seconds. Raise fully and hold up 1–2 seconds. Repeat if auto function doesn’t return immediately.
3. Power liftgate (if equipped)
   • Open and close the liftgate using the interior or key fob switch. If height memory was set, reprogram as desired per owner’s manual.
4. Moonroof/sunroof (if equipped)
   • Cycle fully open, then fully closed; press and hold the close/tilt switch for a few seconds to restore auto/jam protection.
5. Clock, radio presets, and drive mode preferences
   • Re-enter time, radio presets, and any custom settings.
6. Steering angle/traction control
   • The system self-calibrates. A short straight-ahead drive after startup typically clears any temporary VSC/traction lights.
7. Smart Key system
   • Usually automatic on reconnect. If the fob is unresponsive, press the START button with the fob held near it, then start the vehicle normally.

Signs of a failing battery

• Slow or labored cranking, especially after the vehicle sits overnight
• Dim or flickering interior/exterior lights; rapid clicking from the starter relay
• Intermittent warning lights (ABS/VSC) right after startup that clear after revving
• Electrical glitches: power liftgate or window auto functions dropping out
• Battery case swelling or corrosion buildup on the positive terminal
• Repeated jump-starts needed or a battery older than 4–5 years

Common battery issues for this generation

• Wrong group used: A standard 24 will not fit/align correctly; the Highlander needs 24F (reverse terminals). Misfit batteries can strain cables or short at the hold-down.
• Parasitic draw complaints: Door/liftgate ECUs, aftermarket alarms/remote starts, and telematics add-ons can create key-off drains. If the new battery dies in days, have a draw test performed.
• Corrosion under the terminal covers: Clean with a baking soda solution, rinse, dry, and apply a protective spray. Ensure the vent path is clear on AGM units installed inside the vehicle.
• Short-trip driving: Frequent brief trips prevent full recharge. Consider an AGM upgrade and/or periodic maintenance charging.
• Loose or over-tightened hold-down: A loose clamp causes vibration damage; over-tightening can crack the case. Torque snugly and recheck after a week.
