Hi,

My gas mower just caved on me. I am considering buying one of these mowers and I have to take many things into consideration including how often I need to replace the battery which is quite expansive.

The specification for the battery did not mention lifetime of the battery. Like any rechargeable battery, there is a lifetime with directly related to the number of charges before it can no longer hold the charges effectively. For instance, after how many charges will the battery only be able to hold 45 minutes, 30 minutes, and 15 minutes of charges respectively?

Thanks,
Michael

You're going to get a fuzzy answer at best.  Lithium Ion battery technology is much better than the previous technologies, e.g. Ni-Cad, Ni-MH, Lead Acid, etc.  Ego warranties their batteries (and chargers) for three years. 

As these came out in 2013, we're only now getting to the point where the warranty is expiring.  With that said, I have a 2.0 AH battery with a 2013 manufacture date (which I bought second hand), so I don't know the true history of how it was used before I got it a year or so ago.  This battery has about 92% of it's capacity left, which is pretty good in my opinion for a 4 year old battery.  And it's better than the 90% on my 80V Kobalt battery.  That said, it could die tomorrow, but I have other backup batteries.

Here's a thread on how to measure battery health.
