Parts for your 2020 Toyota Land cruiser-Batteries

2020 Toyota LandCruiser batteries: what they do and how to look after them

Per Toyota’s owner’s manual and workshop literature for the 200 Series, the 2020 Toyota LandCruiser runs a 12‑volt lead‑acid starting battery. Many AU/NZ diesel VDJ200 models are factory‑equipped with a dual‑battery setup, while petrol URJ200 variants generally have a single battery. The Smart Key remote also uses a small coin cell (CR2032). So yes—batteries are very much part of this vehicle.

The battery (or batteries) on a 2020 LandCruiser does the heavy lifting when it comes to starting under the bonnet, supports electronics when the engine’s off, and stabilises system voltage when the alternator’s busy. On dual‑battery rigs, an auxiliary unit keeps fridges, lights and winches humming without flattening the starter. For touring across Aussie or Kiwi backroads, a healthy battery setup is essential kit.

As part of routine servicing, it’s worth checking state of charge and health. A fully charged battery should rest around 12.6–12.8 V, with the engine running, the alternator typically holds 13.8–14.5 V. In hotter climates, frequent short trips, or with plenty of accessories, expect replacement closer to 3–4 years, in gentler use, up to about 5 years is common. Flooded lead‑acid is fine for light duty, but AGM often suits dual‑battery and winch work thanks to better vibration resistance and higher discharge tolerance.

• Watch for slow cranking, dim lights, warning lamps, swelling cases, or a sulphur smell—these are signs it’s time.
• When replacing, keep power if needed to maintain presets, always remove the negative clamp first and refit it last.
• Clean and tighten terminals, use anti‑corrosion spray, and ensure hold‑downs are snug for off‑road vibration.
• Choose a capacity and CCA that match your engine and climate. Common fits include N70/N70ZZ, DIN95‑type, or Group 27/31 equivalents, check tray size and terminals.
• For dual systems, use a quality isolator or DC‑DC charger so both batteries charge correctly under a smart alternator.

A quick battery test at each service saves headaches, especially before long hauls. If the LandCruiser cranks a bit lazy on a cold morning, don’t push your luck—sort the battery before the next mission.

FAQs

What battery type and size suits a 2020 LandCruiser?

Most AU/NZ diesel 200 Series use high‑CCA units such as N70/N70ZZ or DIN95‑style, with many owners opting for AGM for durability and accessories. Petrol models may use similar capacity or Group 27/31 equivalents. Always match CCA, physical size, and terminal layout to the tray and hold‑down in your specific variant.

If running a dual‑battery system for touring, pair batteries with similar chemistry and use a proper isolator or DC‑DC charger to keep charging spot on.

How often should the battery be replaced?

Plan on 3–5 years, leaning shorter with heat, corrugations, winching, and short‑trip driving. Test at each service, if cranking slows, voltage sags, or a load test shows low reserve, replace before it strands the crew.

For dual setups, remember both batteries age, monitor them individually so a tired auxiliary doesn’t drag down the starter.

Does the 2020 LandCruiser have dual batteries from factory?

Many AU/NZ diesel VDJ200 trims were factory‑fitted with dual batteries, while others and most petrol variants run a single starter battery. Plenty of owners add an auxiliary battery for fridges, lighting, and recovery gear.

If adding one, mount securely, fuse close to the positive post, and use a quality isolator or DC‑DC charger compatible with the vehicle’s charging strategy.
