I've had an Odyssey Performance Group 48 H6 Battery - ODY-48720 in my 2014 for a little over 2 years, and it's been trouble-free.
Odyssey H6. The only one that’ll last because they’re the only manufacturer using virgin lead in the manufacturing process now.

When Johnson Controls took over optima they changed the formula of their process to use recycled lead and it half lifes the battery.
