I had a couple of Optimas back in the early 00’s that I took from truck to truck to truck. I had a couple of them for about 10 years. they used to be nearly indestructible.
My 09 yellow top just bit the dust. I was able to get it charged back above 13v but it's so old I didn't want to risk it with winter coming.
Got my yellow top in my 2000 subaru forester still going good 4 years up north where it gets cold
My old Celica was at 11 years of daily on a Yellow Top, including at least 3x when it sat to dead and recharged just fine. When I got a new car and stopped driving it, it only lasted another 6 months of infrequent driving after that.
I had a yellow top that lasted me through 3 cars and over 12 years. I sold it with one of my cars. Those were the good ole days where they actually were decent.
ive got my early 2000's redtop it still sits at 12 but it gets alarmingly hot when in use, best battery ever, over 10 cars
I actually like this change. It's telling me the actual battery charge. What I don't like is at least on my S 8 Ultra is it hits 85%, then starts discharging the battery. The battery gets as low as 81% before charging again. Personally I think this charge / discharge cycle is going to be more harmful long term than just charging to 100% and holding there. So I ended up turning it back off.
my yellow top won't hold a charge after two winters in my project car. will never spend another dime with them
Bought a new one and had to warranty it 6months later.
All since lifespan has been 2-3 years. I only sell them at customer request…
