I have the 56 volt self propelled EGO mower and was very impressed
until the 3rd year or
so when the battery wont charge and all I get is blinking red lights.
The replacement
cost for just the battery is over $300. Is this usual to wear out tht fast?
They only offer a 3 year warranty on their batteries and chargers.
I own 3 7.5 AH batteries, a 5AH one, and 4 2.5 AH batteries (plus 2 fast
chargers and several regular chargers). I've never had any of the
batteries or chargers fail....but have heard from others that they
sometimes do.
After 3 years my 7.5 AH batteries are down to about half capacity (but
my 4 year old one is still at half capacity, so the capacity loss
appears to slow down after the first 3 years....) so you will have to
eventually buy a 2nd or a replacement battery.

(More than a year out of date..about time for me to publish a 4 year
update...)
My mowing area is maybe a gtenth of an acre and my mowing need is modest.
I always completed it on one charge
though did get down to blinking red maybe a half dozen times.
[with a 1/10th acre lot you may not need a 2nd battery, but I need 2-4
batteries to mow my entire lawn depending on the season/weather...]
But am loath to put $300 more into it, not knowing if it is the
battery or the charger.
To check, I disasembld the battery and lightly charged up any low
cells to match the
others (there was no significant mismatch anyway), but still the
charger wont charge it.
Blinking red light on the charger can indicate a high-temp situation on
the battery (at which point it turns on the fan but doesn't charge until
the high temp is reduced). But it can also indicate a battery failure
(or possibly a charger error, but those are usually indicated by no
lights....]
You can pick up a used regular charger relatively cheap on Ebay to test
the battery for sure, but my guess is that it is probably a battery issue.
Several of my batteries (one 7.5ah, one 5ah, and a few of the 2.5 AH)
came with used EGO equiptment I purchased off of Craigslist...buying the
batteries with a kit of equipment that includes
charger/battery/equipment is the most economical way to go for the 2.5
AH batteries if you are buying them new and need something like a
chainsaw, weed wacker, blower, edger, etc...
