Battery OEM Toyota or Deka

My Mechanic had me get non-AGM style from Deka. I have the dual battery setup, and have drained my spare a few times already and it’s out performed the previous brands.

See alot of "battery replacement cost" blah blah. 1) I have had 4 hybrid work cars (3 Camry and 1 Prius) All driven to 150k or more miles without battery issue. 2) Battery is warrantied by Toyota for 10 yrs unlimited miles 3) If you drive car alot the battery will last along time. If it sits 5 days week and you dont drive alot the battery has a small chance to be bad in 10 yrs. 10 YEARS and that like worst case if sits and not driven combined with being outside in really hot or really cold or both (Northeast). I've never seen it though in 4 cars.

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

I have put 50k+ miles on my 09 Highlander Hybrid in the last 2 years. It charges to 76% and provides 27-30mpg depending on conditions. I love it.

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

I had a 2008 Highlander hybrid that I sold to a coworker. The battery is still strong but the fan that cools the batteries gave out. He had that fixed and it is still running fine today.

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 really like the Deka ETX12. Point is these batteries are bulletproof. They last longer than any other battery I have ever gotten. I highly recommend them.

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?)

Switched to a stock mk5 4cyl battery though as the Deka couldn't handle sitting for more than a couple days without being on a trickle charger.
