I've got a spare set of batteries that I rarely use. I fully charge them and box them. When I do need to use them, shall I recharge them before using or will they still be 100% and ok to use after a week or 2 of storage.
18650’s are ok at a full charge for a good few weeks dude.
It’s only when you’re storing them for months you could do with dropping them down to their nominal voltage.
I got a some spare batteries out the other day had not used them for maybe 2-3 months they still had like 90% charge but I did balance them out in a external charger before use.
