There is no way a battery could last that long, even with newest and greatest technology, unless u pushed for 300k km in a year, than sure

Conclusion: No need to argue with those wanna drive Myvis but wanna demotivate others to avoid futuristic cars.

Bro, I used to own the Camry Hybrid until 2 months ago. Have you had the pleasure?
I did the numbers. Extra 500 bucks road tax. Extra 300 bucks insurance. Sure, the low profile was fun to drive, but every time it rained, I had to take evasive action. I saw my neighbour with a Civic Hybrid fork out over 10k ringgit when he developed problems with his inverter equipment.

So if you haven't owned one, don't try to sound like you have!

one thing you need to note is that. battery is not the only thing you need to consider.

from what i know, hybrid cars, different parts also is for hybrid design, which is more costly than a petrol car.

but then again, i'm not against buying one second hand. just see if its suit you. like other said, if its not a city stop-go drive, then your saving could be reduced.

Well, how long your Lithium battery last? It is stated that the Lithium is designed to have 500 time recharge but well I can say it can last more recharge cycle, However, how long the battery last between recharge? I believe you know that the time for every recharge get shorter and shorter. 

Some manufacturers are very transparent about the degradation.

In my Volvo for example:
- 96 cells battery in 6 modules (16 cells in each module)
- you can't change individual cell, but can change single module
- Use only 73% of the battery where empty = 17%, full = 90%
- designed degradation rate is with 2x full charge daily on 300 days a year, battery capacity remain > 70% over 15 years
- long term storage recommendation is store with 1/4 battery level. Check and top up every 6 months.

One full charge is 40KM of pure electrical drive in hybrid mode (50KM if deliberately set to Pure mode), it is true to real usage for me.

So 2x full charge = 80KM, 300 days = 24,000KM on pure electric drive a year.
That's more than normal people can charge unless one have charger at both work and home. Most people only able to charge on way due to limited charging stations.

Ya, completely agree with you, you change it when it degrade below your practical usage.
We know battery will degrade when we buy the car, there are other features we value that makes us want the car, when time comes just replace what degraded/gone bad. If you drive 100,000KM on ICE, piston ring leak lubricant also what.

Some people want to buy big car like Camry, but not willing to pay service, wear and tear maintenance, not even willing to pay road tax and insurance. He win liao loh.

Can elaborate how your brother fail to claim warranty for the HV battery? AFAIK, battery degradation is allowed to claim warranty. I mean, how can you expect the battery not to degrade?

So far nothing broke or need any major replacement after 3.5 years.
