what is the life expectancy of the 7.5ah battery? How should I store the batteries for the winter when I will not be using them?
Regarding life expectancy: Battery life is usually measured in terms of recharge cycles, so it’s tough for us to predict the exact number of cycles your battery will produce due to all sorts of usage and environmental conditions. It is because of this, as well as for our customers’ peace of mind, that we offer the three year warranty. Also, here is a corresponding thread that might be helpful: https://community.egopowerplus.com/ego/topics/what-is-the-life-expectancy-of-the-7-5ah-battery
Charge/discharge cycles aside, since the warranty is 3 years, life expectancy is...3 years. Now, if you buy the extended warranty..... Just kidding about all of the above. Got a few uses before winter set in and then I didn't even use any of my Ego stuff for nearly 6 months over the winter/early spring. I expect the batteries to last a good long time. Note that everything was kept in our garage which is unheated and uninsulated. So, not *as* cold as directly outdoors, but cold enough. 5ah battery was in the mower and 2.5ah was in the string trimmer. They both got a charge before first use this spring. Both performed perfectly.
Looking in the manual, I don't see an answer to this battery question: When I charge the battery, and the lights indicate that it reaches full charge, should I take it out of the charger or leave it in the charger until I mow again. I'm asking where the battery should be, after charge, during the weeklong wait between times that I mow? In the battery charger? Or in the mower? Or neither? Thanks.
