Yeah I always thought it was a myth, but... Name brand, especially for rechargeables, is important. For alkaline? I like Energizer batteries myself. From my caving days, they were always better than Duracell or others. For random coin cells of course I've bought various random ones off Amazon, but the only ones that really last are name brand. I've seen the same with the lithium AA, 9V, etc too. I have yet to find a random lithium brand for AA that seem like an actual better deal than the Energizers. For AAA, who knows as in my experience they all suck.
And for whatever reason, replacing SLA in small UPS doesn't seem worth it either. They never seem to last very long! With absurd shipping costs, you're almost better off just buying a new small UPS. I know some have had success using Li-ion replacements for SLA, but that varies too based on personal experience. We got a single Li-ion battery for our golf cart vs lead-acid. It was about $1k vs around $800 for lead, but it weighs about 500# less. Now that cart is FAST!
