The majority of EVs still use lithium ion batteries.  The figure I've come across is that only about 30% of EVs use the newer LFP batteries.

 

No. Not globally.

By 2026, over half of all new Electric Vehicles (EVs) produced globally are expected to use Lithium Iron Phosphate (LFP) batteries. LFP market share, which exceeded 50% in 2024 and continues to rise due to lower costs and higher safety, is driven by major adoption from manufacturers like Tesla, BYD, and Ford.

 

As quoted earlier...

So, no, when you claimed batteries MUST be replaced after 10 years, a while back, think it was about 12 months ago, it wasn't correct.

Sure, something like a Gen 1 lithium ion ternary if not looked after properly and fast charged a lot in a less than optimal climate will most likely lose significant capacity after 10 years. 

A direct answer to your claim below...

No, an EV battery does not typically need to be replaced after 10 years. Modern EV batteries are designed to last 15–20 years or more, often outliving the vehicle itself, with an average capacity loss of only about 1.8% to 2.3% per year. While 8–10 year warranties are standard, most batteries continue to function well beyond that, simply offering slightly reduced range. 

 

If you'd have said, SOME batteries only last ten years I would have agreed with you but that wasn't what you claimed. You claimed THEY (all or most of them) only lasted 10 years and the owner was stuck with a huge battery cost. Which isn't true.

 

Well done though, for successfully diverting the conversation away from the claim that lithium ion batteries are volatile fire bombs destined to explode at any minute, to.... whether or not you were right last year when you claimed they were FUBAR after 10 years. You should have been in politics. 😀

 

This guy makes a good point regarding modern thermal management.

 

 

 

 

Wow, now this is impressive, below, I've never owned a petrol car that was capable of doing anything like that mileage....

 

Quote

Lithium-ion batteries in electric vehicles, particularly Tesla models, have proven capable of lasting over 400,000 to 500,000 miles, with some high-use taxis exceeding 424,000 miles on their original battery. While 150,000–250,000 miles is typical, proper care enables significantly higher longevity, with future technologies targeting a 1 million-mile lifespan.

 

I was feeling colorful today.

You're either bat-s*** nuts, or you're trying to gaslight me, which won't work.  

I talked about lithium ion battery issues years ago, well before most EVs had the newer LFP batteries, and you know it.

You were wrong.  Get over it.

This will be my last post here.  I'm done arguing with someone who won't be honest.

Nope. And you've ignored the bit above regarding...

" Real-World Data: Studies indicate that batteries in newer EVs, particularly those produced after 2015, have extremely low replacement rates (under 1% in some reports)."

 

That's extremely low replacement rates right back to 2015. Id never heard of you back then. 😂

You've also ignored the huge milage of original batteries, like the high use Tesla taxis exceeding 424,000 miles on the original battery. That's not LFP.

You've also ignored this....

"No, an EV battery does not typically need to be replaced after 10 years. Modern EV batteries are designed to last 15–20 years or more, often outliving the vehicle itself, with an average capacity loss of only about 1.8% to 2.3% per year. While 8–10 year warranties are standard, most batteries continue to function well beyond that, simply offering slightly reduced range. "

 

------------------------------

Here's loads more for you to ignore...

"Electric vehicle (EV) batteries are lasting significantly longer than expected, with studies indicating they often outlast the car's usable life. Modern EV batteries typically retain 80-90% capacity after 8-10 years, with real-world, dynamic driving conditions potentially extending their life by up to 40% compared to lab tests. 

 

Key findings on EV battery longevity:

• Performance Exceeds Expectations: A 2026 UK study of 8,000 EVs found an average state-of-health (SoH) of 95%, even in vehicles up to 12 years old.
• High Mileage Durability: High-mileage vehicles (100,000+ miles) showed 88-95% battery health, proving that age, rather than just mileage, is not a significant cause of degradation.
• Real-World vs. Lab Results: Research from Stanford and SLAC found that "dynamic" driving (real-world stop-and-go) can make batteries last up to 38-40% longer than the constant, steady"gentle" driving often used in lab tests.
• Long-Term Lifespan: While 8-year warranties are common, many batteries are projected to last 15-20 years or more (300,000+ miles).
• Factors in Longevity: Advanced thermal management offers improved cycle life.
• Exceptions: Extremely hot, consistent temperatures can accelerate degradation. 
   

While early-generation EVs (pre-2016) had higher replacement rates, newer, modern EV batteries are proving to be exceptionally durable. 

 

‐-----------------------------

 

Notice above, after 2016 proving to be exceptionaly durable. Unless you were named something else I'd never heard of you back then. 

 

Notice above, lasting longer than expected, often 80 to 90% capacity after 8 to 10 years.

 

Notice above, 95% capacity seen in 12 year old batteries.

 

Notice above, age not a significant cause of aging, its about milage.

 

But of course, none of this is what you want to be true so will remain impossible for you to accept.

 

You claim to "like EV's but then you take every oportunity to emphasise and exagerate the negatives.
