MG ZS EV battery
health check. £79.

The MG ZS EV is the UK's most affordable mass-market EV and increasingly common on the used market. Less independent battery data exists for MG than established brands, making an Aviloo check particularly useful before purchase.

Why check an MG ZS EV?

Less independent data. More reason to check.

The MG ZS EV uses CATL lithium-ion cells with liquid thermal management. It is a credible setup and early data suggests reasonable longevity. The challenge is that unlike Nissan, Tesla or Hyundai, there is significantly less independent long-term battery data for MG available. Used buyers often have more uncertainty about what they are getting.

The two main variants, the 44kWh pre-facelift model and the 72kWh post-2021 version, behave differently. The smaller pack shows faster proportional degradation over mileage. An Aviloo test removes the guesswork entirely.

Higher degradation risk
  • 44kWh pre-facelift at higher mileage
  • Frequent DC rapid charging
  • Uncertainty around longer-term longevity
  • Limited independent resale data
Lower degradation risk
  • CATL cells generally reliable chemistry
  • Liquid thermal management fitted
  • 72kWh battery handles use well
  • MG battery warranty support
Typical SOH for MG ZS EV

What to expect.

2019 to 2020
Typically 85 to 93% SOH. 44kWh models at 4 to 5 years. Check carefully.
2021 to 2022
Typically 88 to 95% SOH. 72kWh facelift. Generally good retention.
High mileage 50k plus
Typically 83 to 92% SOH. Varies by charging behaviour.
Younger 2023 models
Typically 92 to 97% SOH. Near-new. Strong result expected.

Common questions

MG ZS EV FAQ

Is the MG ZS EV battery reliable?

The MG ZS EV uses Chinese CATL cells which have generally shown good durability. However, it is one of the less tested EVs in independent studies compared to Nissan or Hyundai, and used examples come without the same depth of battery data as more established brands. An Aviloo check is particularly valuable here.

What SOH should a used MG ZS EV have?

A 2020 to 2022 MG ZS EV should typically show 86 to 94% SOH on an Aviloo test. The smaller 44kWh battery in pre-facelift models may show slightly higher degradation per year than the 72kWh version in later models.

Does the MG ZS EV have active thermal management?

The MG ZS EV has liquid-cooled battery thermal management, which helps protect the battery during fast charging and in varied temperatures. It is a step above passive cooling but less sophisticated than the system in a Hyundai or Kia.

Why are Aviloo checks particularly useful for MG?

There is less independent data on MG ZS EV battery longevity than on established brands. The Aviloo test gives you a cell-level measurement rather than relying on the BMS readout or the seller's claim. At the price point of used MG ZS EVs, the £79 test cost is well justified.
