After 7 years on my Duracell group 27, I upgraded to a Northstar Power X2...I have these in my entire fleet and they are the best batteries I've ever used...my oldest us 9 years old and showing no signs of being tired...the runner feels like it starts like I'm using lightening! Ha!
Time to clean the engine bay! Sheesh!!![]()

I got that same battery for my 04 4Runner. I have had really good experience with this line of batteries.
Did you do the voltage mode? The AGM style battery requires a big more charging than a lead acid battery. Dirty Parts makes it easy for the 4th gen.

Be sure to read the note before ordering as there are a few variations.
Yes, these are terrific batteries! I actually use a Ford diode found at most autoparts' stores that increases the alternator output to 14.8 while charging and holding 13.8-14.2 while cruising...I do the same in my tundra with great success and a happy AGM! Here's a GM version of what I used...literally the same thing...Amazon.com
Just hit a quarter million with my '07 Sport. Love this truck.
