Need to address this problem again: https://turbobuick.com/threads/optima-red-top-battery-info-request.444761/
I replaced the previous Optima 34/78 Red Top under warranty. The new battery has performed as poorly as the previous one. Warranty expires mid February. What else is out there? Must be a sealed battery.
The mounting location & retention strongly favors the Optima sizing, rounded corners & the mounting clamp at the base.
Battery needs to reliably crank a tight 500 cid engine with almost 10:1 compression. The Red Top can spin the engine most of the time when it is cold. Can't do it when it is up to operating temperature. I don't think the starter motor is suffering from heat soak, as I've been able to place my hand on it. (Plus a jump start usually spins it easily) Electrical load consists of OEM lighting, heater blower motor, windshield wipers, stereo, gauges, plus the addition of HEI ignition, separate electric cooling fans on radiator & tranny cooler. Alternator is 150 amp Powermaster. This is a four wheel drive application.
Weight savings would be a plus, but not at the cost of reliability.
Thanks.
