So I bought this EverStart Platinum H6 battery on Friday to replace the OEM H6 that is currently in my 2015 Cayman, and is now nearing the 9th year on this planet. Recent testing of the OEM battery is showing that is now on the brink of needing to be replaced, and the Start/Stop functionality of the car isn't taking place at all anymore, which is the first sign that the car is protecting the battery.
So, first thing I did after getting the battery home from Walmart on Saturday is hook up my Ancel BST200 tester to it, and I was shocked at how poor the results were for a battery with a 10/23 sticker is. I should have taken a picture at the time, but I didn't. The results I can remember was 550 CCA, resistance of over 4.8, and the SOH was 72%, with SOC being around 84%.
So, first thing I do is toss hook up my 0.75A Battery Tender, for a nice long, slow recharge.
After 16 hours, the BT shut off, and then the readings were 100% SOC, but the resistance is in the 4.7 range, and SOH is only 78%.
That just doesn't seem good enough for a brand new battery to me, or am I off base?
So I then hooked it up to a 1.25A Battery Tender, and let it go again until it shut off.
I unplugged it, and let is rest over night, and now here are the results:
So what do you think?
Should I put it into service, or should I return it to Walmart, and hunt down a better one instead?
As you can see, this it the South Korean version of the battery, and I'm not convinced I'm going to get a long service life from this battery.
Though, I do have to admit that the resting 13.04 Volts is way better than what's in the Cayman right now.
Here's the results on the Cayman's OEM battery after spending all night on the 0.75A charger:
Thanks for your opinions.
