I put an Optima 75/35 Red Top into my first Subaru, an MY01 RX Liberty in mid 2001, this battery is now living in my MY03 XS Forester.SuperRu said:I just put a new Optima 34R in JudyRu's 98 Forester. It replaces an Optima that I bought new back in 1997. It still worked fine, but I didn't want to chance it with a battery that old. They can't last forever? Can they?
I have a 51R in my XT after donating my OEM battery to my sister in-laws 98 OB. This is her third battery.
My Optima has let me down just the once in 2003, I had an Earth leak which drained the battery "dead flat", we (Battery World) could not find the fault so they charged it up enough to start the Liberty as I had a specialists appointment 100kms away late that morning, the remainder of the charging has been done in the car and it hasn't failed since.
SupeRu as for the age question, I based my purchase upon the Testimonials from the USA Optima website and specifically upon this one
Here is the site http://www.optimabatteries.com/publish/optima/americas0/en/config/product_info/technology/testimonials.html#000100010004"I believe these batteries have evolved into a very good cold weather battery as our vehicles crank over well in temperature extremes down to -50°F. Also, no problems have occurred from summer heat. Since 1987, 50 of the original 65 are still in service."
