Toyota Yaris Hybrid Battery Replacement Guide: Ni-MH vs Lithium-Ion, OE Numbers, Cost & Buyer’s Checklist (2011–2025)

1. Why This Guide Matters

The Toyota Yaris Hybrid has been one of the world’s best-selling compact hybrids since 2011, with more than 4 million units sold across the XP130 (3rd gen), XP210 (4th gen) and the Yaris Cross variants. Every Yaris Hybrid on the road today will eventually need a traction battery replacement \u2014 typically between 8 and 12 years of service, or 150,000 to 220,000 km depending on climate and duty cycle.

For wholesale buyers, distributors, and aftermarket service shops, the Yaris Hybrid market is a recurring revenue stream. But there is a catch: Toyota switched battery chemistry between generations. A 3rd-gen Yaris Hybrid uses a nickel-metal hydride (Ni-MH) pack, while the 4th-gen Yaris and Yaris Cross use a ternary lithium-ion (NCM) pack. Ordering the wrong chemistry is the single most common sourcing mistake we see from first-time importers.

This guide walks you through the chemistry transition, the OE part numbers you must match, the realistic price band in 2026, and a 7-step checklist that protects you from counterfeit or mis-spec’d packs.

2. Yaris Hybrid Battery Generations at a Glance

Note: the Yaris GRMN and the GR Yaris hot-hatch are not hybridized \u2014 they use a 1.6L G16E-GTS turbocharged engine only and have no traction battery.

3. Ni-MH vs Lithium-Ion: What Changed and Why

3.1 Third-Gen Ni-MH (2011\u20132022)

The Ni-MH pack in the XP130 uses 40 D-size cells wired in series, giving a nominal 144 V. Each cell is rated around 6.5 Ah, for a total pack energy of roughly 0.94 kWh. Ni-MH is forgiving: it tolerates partial state-of-charge operation, overcharge events are rare thanks to the Toyota hybrid ECU, and the chemistry is thermally stable from \u201330 \u00b0C to +60 \u00b0C. For tropical climates (Middle East, Southeast Asia, sub-Saharan Africa) and cold-climate markets (Northern Europe, Canada), Ni-MH remains the more robust choice.

3.2 Fourth-Gen NCM Lithium (2023\u20132025)

From the XP210 onwards, Toyota migrated to a prismatic NCM lithium-ion pack. The nominal voltage is 177.6 V across 48 cells, with a higher usable energy density (around 1.2 kWh). NCM lithium packs are lighter by roughly 11 kg compared to the Ni-MH equivalent and support a wider state-of-charge window, which improves EV-mode duration. However, they require a Battery Management System (BMS) with cell-level voltage balancing and are more sensitive to deep discharge. For distributors, this means extra handling care during transport and storage.

4. Realistic 2026 Pricing for Wholesale Buyers

Pricing for aftermarket Yaris Hybrid packs varies widely by region, certification (UN38.3, CE, UL1973), and order volume. The table below reflects typical FOB China factory prices for OEM-grade replacement packs in 2026:

Two practical notes:

• Module-only pricing: instead of a full pack, many service shops buy 1\u2013 replacement modules (each module = 8 cells for Ni-MH, 12 cells for NCM). Module pricing is typically 35\u201345% of full-pack price and is the easiest way to enter the Yaris Hybrid aftermarket with low capital risk.
• Customs HS code: Ni-MH packs usually classify under 8507.60; lithium-ion packs under 8507.60 as well but with stricter MSDS, UN38.3 and 1.2 m drop-test documentation. See our 2026 lithium battery export playbook for the full documentation checklist.

5. The 7-Step Buyer’s Checklist

1. Match the OE number, not just the model year. The same year range can have two different OE numbers (e.g. 2011\u20132022 Ni-MH: G9510-52030 / 52031 / 52032). Always cross-check the OE printed on the original battery label before placing an order.
2. Confirm the BMS protocol. 4th-gen Yaris packs include a BMS that communicates with the Toyota hybrid ECU over CAN bus. A non-OEM BMS may throw a P0A80 code after installation. Ask the supplier for a plug-and-play compatibility certificate.
3. Verify cell matching data. Quality suppliers provide per-cell voltage and internal-resistance matching sheets. A matched pack should show < 5 mV delta between cells and < 1.5 m\u03a9 internal-resistance delta.
4. Request cycle-life test reports. A reputable Ni-MH pack should deliver ≥ 2,000 cycles at 80% depth-of-discharge. NCM lithium should deliver ≥ 3,000 cycles at 80% DoD. Ask for the test report \u2014 not a marketing PDF.
5. Check the warranty terms in writing. Industry standard for OEM-grade hybrid packs is 24 months or 100,000 km, whichever comes first. Avoid suppliers that offer only 6-month warranties \u2014 it usually signals cell-grade mismatch or rebuilt packs.
6. Inspect the welding and bus-bar finish. Laser-welded nickel bus-bars (Ni-MH) and ultrasonic-welded aluminum bus-bars (lithium) should show uniform, spatter-free joints. Cold solder joints are the leading cause of field failures within the first 12 months.
7. Plan logistics with UN38.3 + MSDS. Lithium Yaris packs ship as Class 9 dangerous goods and require UN38.3, MSDS, and a 1.2 m drop-test certificate for air freight. Sea freight is more forgiving and is what 90% of bulk buyers use.

6. Common Mistakes to Avoid

Across more than 500 Yaris Hybrid battery shipments since 2022, we have seen the same five mistakes repeatedly:

• Mixing Ni-MH and lithium modules in the same pack \u2014 a dangerous mismatch that can cause thermal runaway.
• Buying \u201crefurbished\u201d packs marketed as new. If the price is 30% below market and the supplier cannot show date-code labels on individual cells, walk away.
• Skipping the BMS firmware update. 4th-gen Yaris packs may need a firmware flash after replacement to clear the old pack’s service records.
• Ignoring temperature derating. In Gulf-region climates, lithium packs lose about 20% of cycle life for every 10 \u00b0C above 35 \u00b0C average ambient. Ni-MH is a safer pick for these markets.
• Underestimating core return logistics. For customers in markets with strict customs (EU, GCC, Japan), a defective-core return policy is essential to avoid inventory write-offs.

7. Frequently Asked Questions

How long does a Toyota Yaris Hybrid battery last?

Typically 8\u201312 years or 150,000\u2013220,000 km, depending on climate, driving style, and maintenance. Ni-MH packs in mild climates often exceed 250,000 km before needing replacement.

Can I replace a Ni-MH pack with a lithium-ion pack?

No. The 3rd-gen Yaris Hybrid ECU and inverter are calibrated for Ni-MH voltage profiles. Installing a lithium pack will trigger fault codes and may damage the inverter. Stick with the original chemistry for each generation.

What is the difference between G9510-52030, G9510-52031 and G9510-52032?

These three OE numbers cover the 3rd-gen Ni-MH pack across different production sub-periods. They are interchangeable at the vehicle level but differ in cell sourcing. Always confirm the original OE on the battery label before ordering.

Do you offer module-only supply?

Yes. For service shops that prefer module-level replacement (8 cells per module for Ni-MH, 12 cells per module for NCM lithium), we ship matched modules with full per-cell data sheets.

What is the minimum order quantity?

Standard MOQ is 20 packs or 50 modules. For trial orders below MOQ, please contact our sales team to discuss sample-pack pricing.

Lexus ES300h Battery — Ni-MH vs Li-ion (OE# G9280-47010)

The Lexus ES300h battery question — "lexus es300h battery nimh vs li-ion" — comes up constantly from buyers cross-shopping the ES300h against the Toyota Camry Hybrid and Avalon Hybrid. The answer: all Lexus ES300h model years from 2013 to 2018 (XV60, 7th-gen ES) shipped with a Ni-MH traction pack, not lithium-ion. The pack is a 244.8 V / 34-module Ni-MH assembly using 1.2 V D-size cells at 6500 mAh, OE reference G9280-47010, with module-level replacement part numbers G9280-79010 (single module) and G9200-79100 (stick of 6 cells).

The 2019+ Lexus ES300h (XV70 facelift) is the first ES hybrid generation to switch to a lithium-ion traction pack — a 40-module Li-ion assembly at ~259 V nominal, OE reference G9280-79200, using prismatic NCM cells with a 5.0–5.6 Ah capacity per cell. When a buyer or distributor asks “lexus es300h battery nimh vs li-ion”, the correct sourcing decision depends entirely on the build date stamped on the driver-door VIN plate: pre-2019 = Ni-MH, 2019+ = Li-ion. 2026 wholesale FOB pricing: USD $1,260–$1,580 per pack for the Ni-MH G9280-47010 (used in 2013–2018 ES300h XV60), and USD $1,680–$2,040 per pack for the Li-ion G9280-79200 (used in 2019+ ES300h XV70). Compatible replacement part: Lexus ES300h 244.8 V 34-Module Ni-MH Pack (G9280-47010).

Lexus CT200h Battery Replacement (OE# G9280-76010)

The Lexus CT200h is mechanically a rebadged Toyota Prius C / Toyota Aqua and uses the same 201.6 V Ni-MH stick architecture as the Prius Gen 3 family, scaled down to 168 D-size cells (28 sticks of 6 cells). The Lexus CT200h battery replacement part is OE G9280-76010 (full pack assembly) with module-level replacements under G9280-79010. Production years: 2011–2017 (first-gen CT200h, E10 chassis), 2018–2022 (CT200h facelift for Japan / EU markets — not sold in North America).

Because the CT200h shares its cell lot, BMS firmware family, and CAN-bus handshake with the Prius Gen 3 / Prius C, buyers can source CT200h packs through the same aftermarket supply chain as the Prius — same voltage, same capacity, same balancing profile. 2026 wholesale FOB pricing for our Ni-MH CT200h packs: USD $1,080–$1,340 per pack for the full G9280-76010 assembly, with single-module replacement at USD $36–$48 per module. Compatible replacement part: Lexus CT200h 201.6 V 6500 mAh Ni-MH Pack (G9280-76010).
