Speaking of doomsday, for power outages, I have portable radios that using 18650 batteries and sdcards with music and audio dramas. Probably lose power 2-4 times a year, weather related.
And my local cell internet goes down after 30 minutes of power outage, as the local tower only runs on battery backup. So content on removable storage is the way to go.
- jacquesm 3y agoIf you keep these in long term storage charge them to 3.7V and recharge when they drop to 3.5 or so. That way they will last very long. 50 to 60% of full charge is what you should aim for.
