If BoxLock's battery gets to 20% it will send you a notification alerting you that it is time for a recharge, and again at 10% that way you are never caught off guard by a dead battery.

If your battery were to die, you can plug BoxLock in or use an inexpensive portable charger (you can find one for under $10 on Amazon) and BoxLock should boot right back up so you can unlock it and charge it elsewhere!
