Without doing an autopsy, guesswork is futile. Single example references leave a lot to be desired. When my group 34 died I dug in and found out exactly why. I would not hazard a guess as to -exactly- why the Sam's Club batteries died although have a PAIR of batteries die exactly the same way is curious.
My recommendation is to bite-the-bullet, get on the phone and find a distributor of TROJAN T-105 batteries (places that sell golf cars usually sell batteries, or call the nearest golf course, ask for the "Pro Shop" and get a reference there).
I had too many hilarious experiences with brands competitive to Trojan to encourage me to think about using an alternative. Including have 10 out of 12 (major competitor) batteries die outright out me on a 10 month trip to Baja California. The batteries were given to me by OEM, free. But they weren't free. The hassles cost me hundreds of dollars.
Things may have changed in the last 20+ years but sampling has not. A battery review is valid if a battery has failed, and times and circumstances have been described. Some "star reviews" have nutso five-star ratings "Well I have had brand X batteries for 1-2 years and I love them *****". Worthless and it skews factual information. Read each review starting with 1 star and go backwards up through 2 and three star reviews.
I had NEVER encountered a bunch as biased toward Trojan, and reluctant to try other brands and owners and pro shop managers of golf courses. If I asked about an alternative brand, I got my ass chewed out. When a dozen golf courses did that to me one-after-another I began to get a hint.
One stupid failed group 34 in a toad cost me several days and several hundred dollars. I don't need to be a mathematician to know it was a poor purchase, although at the time it was the -only- and I mean ONLY alternative. I hate battery problems. Junk that does not work costs a lot of money.
