I certainly do NOT do that.  It probably doesn't hurt anything to do so, but I have two batteries and three devices.  I do have two chargers, but only one "fast" charger, so I only use it.  After I finish my yard work, I immediately charge both of the batteries and then just set them on the floor near the charger.  I have this routine so that I always I know that I'm ready to use them the next time.

Can the charged battery be put in the mower ready for next use in a week or so?

I thought I read somewhere in one of the manuals, or maybe on this site, that Ego specifically recommends NOT storing the battery in the charger.  I'll try to find that reference.

Official Response
EGO's official stance is to remove the battery after charging. However, from the charger manual the battery will not overcharge if left on the charger. Note that I leave my chargers plugged in at all times, but remove the batteries after they are charged.

"5. When the battery pack is fully charged, the charging indication LEDs stop alternating and will shine green continuously. The power indicator on the battery pack will go out. Wait until the cooling fan stops, remove the battery pack from the charger and disconnect the charger from the power supply.

6. The battery pack will fully charge if left on the charger, but it will not overcharge. If the battery pack remains on the charger for one month or more, it will perform self-maintenance and drop to 30% charge capacity. If this occurs, reinstall the battery pack on the charger to recharge it fully."

That's it.  Thanks for finding it.  

I do the same, and take my batteries off after charging, but leave the charger plugged in.

I agree with everyone. I also charge all of my batteries after use and then store them for the next week. I keep my fast charger always connected and my slow charger is still in the box.

I should clarify. I don't always charge mine right after use. I usually charge them just before use or closer to the day I'll be using them. It seems it's better for the batteries to be kept at around 30-50% of charge and just fully charge before use.

Don’t keep it at 100%. Very bad for battery life. Guaranteed to have bad battery right around the 3 year mark. Don’t charge battery until day you want to use it. There’s a reason ego auto discharge to 30% after a while, that’s to preserve battery life. 30-40% is the best range to store batteries for the long term. Can easily extend life to 5-10 years of use. Note, don’t store battery completely discharged either, equally bad if not worst.

Thank you. Having a tough time deciding whether to buy the mower or not- no one able to tell me the average life of a battery if handled correctly.

They have been around for about 5 years now and most are still in service so 5 years +
