If it is not a hassle , then yes it is best to charge before use rather than after use.
Better to store at a partial charge rather than full charge. 
Unless you run it down to red light, then you should give it a partial charge before storage.

The battery management system will self discharge down to 30% after is sits unused for 30 days.

NOTICE:This battery pack is equipped with an advanced self-maintenance function to extend the battery life. Depending on the battery charge, it will automatically perform a self-discharge operation after one month of storage. After this self-maintenance, the battery pack will enter sleep mode and maintain 30% of its charge capacity. If stored for a month or longer, fully recharge the battery before the next use.

Ed, when you add enough EGO tools, you won't need to be concerned over battery storage. My batteries are used year round in rotation and doesn't sit idle for long enough for it to automatically release energy.

I have 2 2.5 ah batteries and 2 5 ah batteries that are in regular rotation. I'll use a 5 ah in the mower and a 2.5 ah in a string trimmer, edger, and blower when I mow my lawns. I generally use the 2.5 ah for other handheld tools like my hedge trimmer. I'll use my 5 ah for the cultivator attachment on the multi-head tool for example.
Anyway, I use one of each until they go to red and then I'll fully charge them. I then start using the other pair that were fully charged right after they went to red. I think I use the batteries frequently enough, especially during mowing season, that I don't worry about charging them right after they go to red. The charged ones rarely sit on the shelf for more than 2 weeks before they get put into use. Once the weather turns cold and growing slows way down then I'll just let them sit and do their self maintenance. Then just charge as I might need them.

I have yet to use my 7.5 Ah in any tool but mower and snow blower. This fall, I may give it a try on my leaf blower just to see how long my arm lass.
