I’ve been using Wyze Lock for a while now and have experimented with different battery types to optimize their lifespan. One common question I’ve seen is about using Energizer Ultimate Lithium AA batteries instead of standard alkaline ones. From my experience, these lithium batteries are a great choice for extending the replacement intervals without any issues. They maintain the same 1.5V nominal voltage as standard alkaline batteries, which is crucial for the lock’s operation. I’ve been using them for over six months now, and the performance has been consistent. The lock responds quickly, and I haven’t encountered any connectivity problems. If you’re looking to reduce the frequency of battery changes, I highly recommend giving these a try. Let me know if you have any questions or other battery tips to share!
