Lynmor, your OP is what conflicts with your latter comments. In your OP you posted “After repairing several battery trays, replacing two windshield washer pumps and replacing alternators in a last ditch effort to get two different vehicles operational, I will not buy even a flashlight battery from them.”
This seems to indicate your battery(s) boiled-over destroying your battery trays, washer pumps, and that you replaced your alternators…. and subsequent posts indicate the problems were resolved.
Since the LAST corrective action you posted before installing new battery(s) was to replace the alternators…. the logical conclusion for readers is that the alternators boiled your battery(s)…. But You appeared to conclude changing battery(s) is what resolved the issue.… not congruent with what you now state.
Sooo… wanna make the story a better read? … then tell us the details ..in proper sequence…if you want us to believe it was the battery…. and even then it makes no logic because the battery should have been warrantied if that was the problem. NOw…. what is your real story…?
OK, two vehicles, one is an old Chevy van and the other is a six year old Tahoe.
Both needed batteries about the same time, so I replaced them with Walmart MAXX. (#1 & #2)
Both of the batteries lost electrolyte that caused damage to battery trays and more.
Voltage readings were correct when running.
Took the batteries back to Walmart and they replaced them. (#3 & #4)
I repaired all of the damage only to have the same leakage.
Took them back, and again Walmart replaced them. (#5 & #6)
I repaired all the damage again, only to have the same thing.
I wondered if the alternators were leaking AC current although none was detected, but I replaced them anyway. The one on the van had a warranty and that one was replaced free.
Repaired the damage a third time but the #5 & #6 batteries continued to cause damage.
Took one battery back and asked for a different model, they refused and gave me the same thing. (#7) Same issue.
All of the above occurred over approximately one year.
Gave up on Walmart and bought two batteries of a different brand, absolutely no more problems. NEVER AGAIN!
