I got onto the Amaron bandwagon because I got tired of Motolite. Just about every Motolite battery I've ever used have failed the same way and usually around the same time after the warranty expired, give or take a few months. There was only one instance when it failed a month before the warranty went out. Even so, they gave me a look like they were making it my fault. They eventually replaced it after giving me a run-around.

FLA batteries should last 3-5 years, minimum... unless there's a genuine problem with the vehicle. But definitely should not coincide with the 18-, 21-, or 24-month warranty.

If this is not a good example of planned obsolescence, I don't know what is.
