Battery Panasonic or OEM Subaru

My MY2007 S2000 also came with Panasonic battery. I replaced it with Walmart battery in last summer (2015), So it ran for 8 years.

Original factory Panasonic battery in my RX-8 lasted 7 years. The 'premium' Exide I replaced it with is on it's way out now after only 4 years.

When I bought my 2006 4Runner V8 three weeks ago, it had the original Panasonic battery on it's last leg and I had it replaced with a Toyota True Start battery. The 4Runner only had 109,600 miles when we had that battery replaced.

My battery keeps dying if I dont use my car for 1-2 days and Subaru is failing to address the issues.

Subaru has had a problem with their electrical systems since 2014. Batteries last 2 years, max. 2018 legacy is on its third battery in 4 years. 13,000 miles. $600.00 in batteries.

Subaru batteries aren't great in the cold either

My battery made for Subaru died on my 2017 Forester 2 weeks before the warranty ran out. SUBARU has their own problems with their batteries.

Subaru batteries suck
