I use this one from Oreillys auto parts since mine is on the firewall and I don't want to look at the optima. 785 cranking amps and so far reliable starts even after sitting for a month at a time.

looking for a good quality negative battery for 51 V8 want American made
We're on a down hill slope. Bought a Timken wheel bearing (thinking top-of-the-line). Came in their Timken box but marked made by *** in Canada. Adding injury to deception, Timken marked up ***'s (US) retail cost (literally) 200 %. Timken's little box is very expensive.
Most all batteries are made in Mexico now including Interstate. Restrictions on lead (heavy metals) and acids are the reason. Just like chrome shops. Really doesn't matter where it's made. AGM batteries like Optima are the best car batteries. Allot of Mexicans have died from lead poison, not just from battery production. You really don't want batteries produced here. Dangerous process. It's well worth the duty to get it out of the country.
Philip, please consider editing your post. I and I'm sure others are offended by the inference that American lives are more valuable than others.
