Car was cranking over slower than usual lately so I replaced the battery. (14 Accord) Ever since then the CVT has "crisped" up, less "rubber bandy" feel. I'm actually very impressed with how it feels now.

Am I imagining things? Any reason this could be real?

What say you...

It will go back to its rubber band like feel once it gets used to things.

Just curious, what did you replace it with? I've heard a lot of people complaining the original 51R does not last very long. I just hit three years on my '15 Accord so I'm keeping my eyes open.

On some vehicles when the battery is replaced the adaptive or learning comes into play. After a few days it will go back to a normal or previous state usually.

Its probably relearning how you drive.

If its still getting the same MPG I'd suggest your seat of the pants computer needs to be calibrated!

I agree that removing the battery resets the computer, and it will "relearn" how to drive.

O'Reilly's three year battery, was about $150. I swapped it at the store so no core charge.

The mileage has dropped! From 33 to 30, same exact driving.

So I guess it's "relearning", good, I'll keep driving it hard and maybe I'll like it better. I really don't care about 3 mpg.

If I'm not mistaken, Honda's will accept group 35 in place of the 51R. I just did this on a 15CRV.

Bet you are correct meep. I would MUCH rather have a good group 35 instead of a 51r battery.

My Santa Fe was like that... When I changed the battery the shifts were much more abrupt for a couple days and then it went back to the way it was. It had adaptive whatever...

I replaced the 51 in my Accord with a 35.
Much more stout battery.
