just curious. if the hybrid battery dies. will the car still be able to run on petrol mode? probaby FC will be based on petrol mode thereafter.

Anyone can advise?

The hybrid Axio I rent, will just continue on petrol, when the hybrid battery died, but it keeps giving warnings.

So if you ignore the "deadly serious" warning, you can continue to drive using the petrol engine.

I recall it was shared here at different threads: Toyota can, Honda cannot.  This is due to the different hybrid technology.

it is true honda hybrid cannot switch to petrol mode if the hybrid batt or motor dies?

It depends on the car model. 
for BMW X5 plug in hybrid. Any anomaly it detected in battery it will shut off everything and prevent you from driving further.

Yes, I’ve actually explored a few other hybrid workshops besides HEVShop. One of the notable ones is JK Repair Hybrid Batteries — they specialize in hybrid battery diagnostics, reconditioning, replacements, and even mobile services across the UK.

🔧 Battery Maintenance Costs (Typical Ranges):

Hybrid battery fan cleaning: usually around £50–£90, depending on location and labor rates. It’s an important maintenance task, especially if the fan is clogged — overheating can reduce battery life.

Battery reconditioning/recharge: ranges between £250–£600 depending on the car model and the warranty you opt for. Some places offer a 12–36 month warranty with unlimited mileage.

Since your PI (Parallel Import) warranty is ending and they haven’t done a hybrid battery check yet, it’s actually a smart move to have it looked at by an independent specialist. Many dealers skip proper battery diagnostics unless there's a warning light.

If you're near Birmingham or surrounding areas, JK Repair could be a good choice — they’re certified (City & Guilds Level 3) and offer full reports after diagnostics.

Let me know if you want a list of checks or a comparison between shops — happy to help!

i can recall many actually voiced concern about cost of replacing the hybrid battery when this hybrid car technology is new. But now many happily embrace EVs with a much much bigger battery without any after thoughts like this aspect no longer relevant. The world has changed so much already.
