Uh...wrong section for the vid, sonic??
I sell these batteries and Iamsonic is totally correct. Everyone else seems to be talking out their ass and how long has that battery guy been selling batteries, a week?
I have not been informed by my rep that the batteries are any different currently.
In addition when I asked about how they would resuscitate a dead optima I was
told 8-10 hours at low charge state. I have Optimas in my Toyota Tacoma, Z3,
SL-600 , Ford Exploder( no misprint) and a 1989 Ford van. The van battery has been
in the truck for 12 years and I can leave the truck parked for 3 months and it still starts.
As far as batteries / alternators here are the facts.Batteries need at least a 70%
state of charge and 12.5 volts to start a car. Alternator output needs to be 12.5 volts
min. and max output of 14.60 to 14.85 volts is seen when testing. However, with a few exceptions, all alternators are regulated at 13.8 volts. When testing for a battery
put a battery tester or load tester across the terminals and check the voltage. Then
while still watching the load tester have some one start the car. If the voltage drops below 25% you need a new battery. Put another way , if your battery is rated as
800 Cranking amps) and it shows 560 on start it is toast.
Advantages of yellow top Deep cycling, no outgasing (no smell or fumes) no leakage of electrolyte if overcharged ( battery acid leaking can damage paint and eventually promote rust, Can be mounted upside down or on their side ( love to dothat in old pickups and Jeeps and they have 2 sets of battery terminals.
As far as the member saying the voltage drops to 8.5 at idle put your meter on the alternator and check the output. If it's also 8.5 you need a new alternator, not battery.
The old ones were fine, imo.Lack of knowledge and experience. It does say AGM on the freaking battery lol..
I've been using optima since the mid 90s. I've never had one go bad before 7 years and I've NEVER seen one (out of hundreds) burn out a cell or melt in person.... You only see that crap on the internet from random idiots posting pics showing under hoods that obviously had shit installers. They usually last 7+ years of brutal abuse for me and I buy them (red, blue, and yellow) exclusively over any battery, if properly installed. I see people using side posts for high current applications that you are not supposed to, and the wonder what went wrong... The side post that melted from an old post way back in 2014 (in this thread) is 100% user error and they clearly state not to use it for high amp situations, although I have used side posts too as secondary grounds and have never seen this. Looks like a loose terminal got hot and melted is all.. Funny how many jerks cant even install a battery, but its true.
Even with only 8 yellows and 1500 amps of draw, I only see 12v and doing [email protected] and [email protected] and they charge back almost as fast as I drain them with my x3 300a Ohio generator alts. Optima isn't the most used battery in performance cars for nothing!
Love my optimas!
