If you know your model year, this matches it directly to a generation. If you only know the compliance year, check the chassis code on the build plate. Imported Alphard hybrids are almost always ATH20W or AYH30W, and the two packs are not interchangeable.
- 2011-2015, 2nd Generation, chassis ATH20W: NiMH, 244.8V, 21 modules (12 x 9.6V plus 9 x 14.4V). From $4,790 fitted.
- 2015 onwards, 3rd Generation, chassis AYH30W: NiMH, 244.8V, 34 x 7.2V modules. From $4,790 fitted.
A 2015 build can be either generation depending on production month. The 3rd Generation launched in January 2015, so a very early 2015 import may still be a 20 Series. If the chassis code is not clear, send us a photo of the build plate and we will confirm the pack before quoting.

Common Toyota Alphard Hybrid Battery Problems
Because the Alphard is heavier than most Toyota hybrids and typically carries a full family plus cargo, the battery experiences more demanding cycling than the same-era Camry or Prius battery.
- The battery cooling fan works harder and clogs faster
- Individual modules can drop out of balance sooner
- Fuel economy degradation appears earlier as the system compensates
- Rideshare and taxi Alphards typically show issues 3-4 years earlier than private owners
Regular battery cooling fan cleaning (every 2-3 years) is the single most effective preventive step for extending Alphard battery life.

Toyota Alphard Hybrid Battery Warranty

Both apply to the 2nd Generation and 3rd Generation at the same price. Full terms are on our warranty page.
A new aftermarket Toyota Alphard hybrid battery is $4,790 fitted at our Belmore workshop for both the 2nd Generation (ATH20W) and 3rd Generation (AYH30W). This includes the pack, professional installation, a full diagnostic scan, and a 2-year / 100,000 km warranty. Refurbished packs are available from $2,500 fitted with a 6-month / 20,000 km warranty. Toyota dealer replacement for the same job in Sydney typically costs $8,000 or more.
Check the chassis code on your vehicle build plate. Chassis code ATH20W is the 2nd Generation (December 2011 to January 2015). Chassis code AYH30W is the 3rd Generation (January 2015 onwards). A very early 2015 build could be either, so send us a photo of your build plate and we will confirm before quoting. The two generations use completely different battery packs and are not interchangeable.
Common warning signs include fuel economy dropping noticeably, the Check Hybrid System warning light appearing, weak acceleration when the vehicle is loaded with passengers or cargo, the petrol engine running more often at low speeds, reduced electric-only driving, and the state-of-charge gauge fluctuating rapidly between full and empty. See our Check Hybrid System warning guide for detailed diagnostic information.
A well-maintained Alphard hybrid battery typically lasts 5+ years, or 150,000 to 250,000 kilometres. Because the Alphard is heavier than most Toyota hybrids and typically carries passengers and cargo, the pack works harder than the same era Camry or Prius battery. Rideshare and taxi Alphard vehicles typically need replacement 3-4 years sooner than private owners.
