Compared to dry batteries, lithium batteries for smart locks are better. The reasons are:
1. Long lifespan: Lithium batteries generally have a longer lifespan than dry batteries and can be charged and used multiple times.
2. High energy density: Compared to dry batteries, lithium batteries have higher energy density and can provide longer usage time.
3. Environmental protection: Lithium batteries are rechargeable, which reduces environmental pollution compared with disposable dry batteries.
