On my first laptop 10+ years ago I had 1 year battery warranty and on month 13 the battery would run for about 10% of original time.
Now I have 5 years old laptop capable of 3 hr of work on original battery.
AGM batteries cost much more, while reports say they die faster than flooded batteries.
There is video on youtube how a guy jumped his car from bank of AA batteries.
So technology exist, but I stick to older batteries for $50 that can last for 10 years
Unless you're routinely running an AGM deep cycle battery below 50%, you should be able to far more from them than a flooded battery. My boss has been running his for 12 years now. I have full expectation that I'll get the same on mine.
