Lifetime warranty batteries emerge

[ME_Andy]

MG (a Chinese brand) has a lifetime warranty now.

CATL is out with a million-mile warranty.

yeah what happens when it doesnt?
Oh your battery isnt covered because car part "insert name" was defective

 

[dubber09]

So, lifetime means 15 years? Or they self destroy right before lapse of 15 year term taking original buyer out along to prevent warranty claims?

 

[Krieg]

15 Years!

 

[ME_Andy]

I don't see anything about 15 years in the MG announcement. Just "lifetime".

 

[Pelican]

It's only good for as long as the EV manufacturer is in business and that is not reassuring given the rate of
closures.

 

[Stumpy]

Is that like "lifetime" or "sealed for life" transmissions?

 

[thomasflaherty]

15 years. Thank God I’ve had 4 lifetimes going for 5.

That is the whole problem with EV. If you run the car 10 years and decide to trade nobody is going to give you decent money for a car that is going to need a replacement battery that costs more than the car is worth.

So it's a good thing I keep my cars for about 20 years. And a 20 year old vehicle isn't worth very much even when they're in good running condition.

For a presentable, good running 20 year old vehicle I typically get $1,500 - $3,000.

How many times MG or the smaller Chinese EV companies out there have been out of business?

CATL isn't going anywhere.

Never. Going.To. Happen.

It might depend on how you define "failed" . Tesla defines failed as being down to 70% of original capacity. It seems 250,000 or even 400,000 miles is possible on many Teslas before loss of 70% capacity.

Loss of battery capacity is fairly rapid initially and then very slow after that. If you defined "failed" as being down to 50% of original capacity current EV batteries would go a very long way. Even so 1,500,000 km (937,000 miles) would be quite an accomplishment.

Meanwhile we need to be realistic about expectations. Not many of us put extreme miles on a vehicle. And not many vehicles ever see extreme miles. There are other limits to vehicle life - rust, crashes, interior wear out, accumulated small stuff.

Our family has had 2 vehicles at all times for the past 50 years. The newer vehicle gets driven the most and the older vehicle much less so. The most we have ever put on a vehicle was 285,000 km (178,000 miles in 18 1/2 years from new). We've had other vehicles to an older age (21 years) though not as many km. So a current Tesla battery should last as long as we would ever need.

True, but they don't make cars. If the car manufacturer goes out of business CATL is not going to warranty it.

How is 15 year, 932,000 miles a lifetime warranty? Do they just mean outliving the rest of the car? I know it's the usual language used in the auto industry now just like lifetime fluids in transmissions. Sure the fluid is considered good for the the lifetime of the transmission, but what's the projected lifetime of that transmission?

Don't get me wrong that's a great warranty and these days on the time alone it's longer than I keep a car. There just has to be a better descriptor, like the actual time and miles instead of calling it lifetime. Maybe that was the intention and the language translation loses it in english.

I thought that was considered the industry standard for battery degradation. I'm sure it could be viewed different over there in order to get to these numbers and maybe by their standard a Tesla pack would match their testing. It would be an important piece of information here.

Wow, Nice! Hope they come to our shores.

"The highlight of the warranty is its unlimited mileage coverage and also the lifetime warranty is not limited to the car’s first owner. It is applicable to both new and current MG customers which reflect the company’s determination and commitment for long-term customer care."

Same could be said about hybrids, but the market doesn't seem to be concerned.
