LiFePo is maybe 10x the lifespan of a normal Lead-Acid battery, if you're cycling it several times a day. A car battery for instance will not do very well in this test. But I'm talking about deep cycle Lead-Acid batteries, cycled every day or couple of days down to 70% capacity (so using 30%). This is a fairly typical workload if you're (for instance) using it as a backup for solar panels. Under those circumstances, the LiFePo battery will die from time elapsed probably about the same time as or maybe even earlier than the Lead-Acid battery dies from cycle count.

- mnw21cam 4y agoKind of. Consider solar panels. A lot of the time, you'll be using around 30% of the discharge capacity to keep you overnight. However, some days will be cloudy, so you might have to use more of the capacity. In this situation, a Lead-Acid will have the full capacity that you bought, but will age like you're using 30% of the capacity most of the time.
- moffkalast 4y agoWell that was interesting, I wasn't aware that flooded lead acid was that much better and that AGM just plain sucks in general, which was also my observation dealing with UPS batteries. Still, I would've expected that ever increasing self discharge would've made them far worse in comparison since it gets worse as the batteries age and you can end up losing major amounts of charge to it. Not sure if that's not as much of a problem for flooded as it is for AGM but I haven't heard it mentioned in the rundown.
