My 2.5 Ah battery didn't self-discharge even after 5 months of storage. Is that a problem?

I charged it to 100 % before winter storage. I stored it for about 5 months indoors, but not on the charger. I expected it to be at 30% power after the period of storage, as a result of the self-discharge operation which is explained in the owner's manual. But I put it on the rapid charger, which indicated that it was at 100% charge, and the charger didn't charge the battery any further (indicating that the battery was already at full charge). Do I need to leave the battery on the charger while in storage for it to self-discharge? Or should it self-discharge even off the charger? If the battery isn't self-discharging, is that a problem? I thought that the self-discharge operation was intended to prolong the life of the battery, but I called EGO customer support and they said that the fact that my battery didn't self-discharge would have no effect on the longevity of the battery. So I'm wondering if the self-discharge function isn't there to prolong the battery life, what is its purpose? Is there any potential problem in my battery not self-discharging?

That feature IS intended to prolong the life of the battery. If it's a feature that's not working, it's defective in my opinion.

Is it going to instantly ruin your battery? No, but leaving the battery fully charged for long periods of time will gradually impact its capacity. I doubt much damage was done after one season, but it all adds up in the long run.

To answer your question directly (oops!), you don't need to do anything special to get the battery into storage mode. It's automatic after sitting unused for 30 days, whether on the charger or not. :-)
