2023 Toyota Camry — Battery Size & Group

Quick answer

• BCI group size (gas, non‑hybrid): Group 24F (top‑post)
• BCI group size (Hybrid): H5 (a.k.a. Group 47/LN2) AGM, vent‑capable
• Recommended CCA (gas): ~650–800 CCA (OEM commonly ~620–710 CCA)
• Recommended CCA (Hybrid 12V aux): ~450–600 CCA
• Reserve capacity (gas 24F): typically ~120–140 minutes; (Hybrid H5): ~80–100 minutes
• AGM vs flooded: Gas trims accept flooded or AGM; Hybrid requires AGM
• Terminal layout: 24F = left‑hand positive (when posts closest); H5 = right‑hand positive
• Physical dimensions: 24F ≈ 10.25" L × 6.81" W × 8.88" H; H5 ≈ 9.56" L × 6.94" W × 7.5" H
• Dual‑battery setup: Not applicable (no diesel option on Camry)

Replacement battery options

• Interstate Batteries MTP‑24F (flooded, high CCA) — common direct fit for gas models
• Interstate Batteries MTX‑24F (AGM) — upgrade option for gas models
• DieHard Platinum AGM 24F‑AGM — AGM replacement for gas models
• Odyssey ODP‑AGM24F — premium AGM, high reserve capacity for gas models
• For Camry Hybrid (12V auxiliary):
  • Interstate MTX‑47/H5 (AGM)
  • Optima YellowTop DH5 (AGM, deep‑cycle capable)
  • ACDelco 47AGM (AGM)

Note: Part numbers vary by retailer line; always verify fitment by VIN, trim (gas vs Hybrid), and equipment.

AGM vs flooded — which does this vehicle need?

• Gas (non‑hybrid) 2023 Camry: The factory battery is typically a flooded Group 24F. You may replace it with the same flooded style or upgrade to an AGM 24F for better vibration resistance and improved performance under heavy accessory loads or extreme temperatures. The charging system is compatible with either.
• Camry Hybrid: The 12‑volt auxiliary battery is an AGM H5 (Group 47/LN2) and must remain AGM. It’s mounted inside the vehicle and requires a vent‑capable AGM design for safety. Do not substitute a flooded battery on Hybrid models.

Post-installation relearn / reset procedure

After reconnecting the battery:

• Clock, radio presets, and trip data: Re‑enter manually.
• Power window auto‑up/down initialization: For each window, key ON (engine running helps). Hold the switch to fully lower, continue holding 1–2 seconds. Then raise fully and hold 1–2 seconds. Repeat if auto function doesn’t return.
• Sunroof (if equipped): Cycle fully open and fully closed, holding the switch an extra 1–2 seconds at each end to restore pinch‑protection calibration.
• Steering angle/vehicle stability control: Will self‑calibrate while driving straight at moderate speed; a warning light may appear briefly and clear after a short drive.
• HVAC/idle relearn (gas models): Start the engine, all accessories OFF. Let idle in Park for about 5–10 minutes until idle stabilizes. Then run A/C for several minutes and take a short mixed drive so the ECM can relearn load and idle trims.
• TPMS: No manual reset for battery disconnect; sensors will report after a short drive.

Signs of a failing battery

• Slow or labored cranking, especially after an overnight sit
• Dim interior or dash lights that brighten with engine RPM
• Intermittent warning lights or infotainment resets when cranking
• Clicking from the starter relay but no crank
• Corrosion buildup at the terminals or swelling/bulging case
• On Hybrid: multiple system warnings after the vehicle has been parked, even though the traction battery is fine

Common battery issues for this generation

• Short‑trip driving: Frequent short trips and long key‑off periods underload the alternator (or DC‑DC converter on Hybrid), leading to chronic low state of charge and sulfation.
• Parasitic draws: Smart‑key systems, telematics, and accessory add‑ons (dash cams, plug‑in OBD trackers) can maintain small but continuous draws. If the car sits for extended periods, use a maintainer.
• Incorrect group size or polarity: Installing a non‑24F on gas models or an H5 that isn’t AGM/vent‑capable on Hybrid can cause cable reach problems, hold‑down mismatch, or safety issues.
• Terminal corrosion and loose clamps: The Camry’s top‑post configuration can develop corrosion over time. Clean with a baking‑soda solution, install anti‑corrosion pads, and ensure clamps are snug but not over‑tightened.
• Cold‑weather cranking complaints: In colder climates, a higher‑CCA 24F (gas) or healthy AGM H5 (Hybrid) greatly improves reliability; weak batteries often show up first on sub‑freezing mornings.
