Best Battery for Toyota Prius

After 16 years and 140k miles, our Prius battery is still going strong.

My neighbor bought a Prius 15 years ago,whoever they came out, the dealer told him it would cost $5000 for a new battery replacement. It lasted until 2024, it cost $1500 to have new battery put in,aftermarket of course

I'm in Australia, and pay $A250 for a Delkor AGM S46B24R or $A340 for a Optima DS46B24R.

I've had great luck with the Optima Yellow Top DS46B24R for Gen2.

My 2006 Prius's original battery went to 150,000 miles before needing replacement.

My old prius was 16 years old and 370.000km battery was fine

My Prius is 13 years old with 187,000 miles still getting 47mpg. I think the battery paid for itself 100,000 miles ago.

I have a 10+ year old Prius C that had a 100k-mile warranty on the battery. It failed at 108k and cost $4k to replace. It's at 230k miles now, and I expect to have to replace it again (but who knows?)

The yellow top is what I have in my car and there is one issue I have with it, the amp hour rating. The yellow top is only 38a/h where the OEM is about 45a/h. This will lead to the inverter using a lot of energy charging the 12v battery and decrease fuel efficiency.

my 2009 had an optima and it only lasted 2 years
