I'm new to EGO and have gone "all in" purchasing the self propelled mower, 16 in chain saw, 15 in string trimmer, and blower. I live in MN so wondering about battery storage over the winter. Do I need to store the batteries indoors or are they ok in the garage where the temps can fall below zero?

Hi Brent,

If you check in the battery manual there's a section describing the temps at which the batteries should be stored, as well as the unique Long Term Storage mode of the Ego battery packs.

But, no, if your garage gets below freezing the batteries shouldn't be stored there.  Best to keep them indoors.

That's what I thought. Thank you for confirming.

That is what I thought, but like Peter, my batteries never discharged over the winter. I too also stored my batteries off of the charger like Peter and had the same outcome. Which led me to contact CS and was told differently than the manual.

That's what I understood also. Plus someone stated on here that their battery was warm after it had been store for a while. Because it was discharging

In my opinion, the manual trumps someone's understanding of the process every time, even if that person has been trained. :-)

After finding two of my batteries warm at the same time I forwarded my concerns and thoughts to Ego, and Jennifer confirmed with Ego's Engineers that indeed the batteries were discharging, on their own, off the charger, as designed. Nothing to worry about.

If batteries are not self discharging they aren't working as designed, unless there's been an Engineering change that has also not been reflected in the manual.

I'd bet that there are some Customer Service personnel who need to be corrected. ;-)

Interesting! That is certainly the way it should work, although mine did not. I wonder if a change was made since customer service thought my experience was normal.

All, we're looking into this conflicting information with our engineers and will get back to you soon about the proper storage techniques. Sorry for the delay.
