Actual battery life of LiFeO4 and Lithium batteries
These battery technologies are being touted as being able to be recharged 1000 to 2000 times (Lithium and LiFeO4) which, even if they were charged / discharged every day / 365 days per year - should give a life expectancy of 3 to 6 years. Thats NOT what I'm seeing customers get. Its more typically 2 years before a new battery is needed. Trouble shooting usually confirms that only a couple cells are the issue, but cells aren't sold individually - ya gotta buy the whole battery.
Those batteries are expensive and buying a new battery every couple years isn't exactly what most customers expect to have to do - especially if the bike has only seen light use.
What are your own experiences please?
