How to choose AA batteries for microphones (updated 2025)

When selecting AA cells for microphones, prioritize chemistry first: high-drain NiMH rechargeables (low internal resistance) are typically best for active mic transmitters because they sustain voltage under load. Lithium AAs (primary) excel for long shelf life and very long run times in cold or heavy-duty environments, while high-quality alkaline cells can be a budget option for occasional use. Capacity (mAh) matters, but so does voltage stability under load and the cell’s internal resistance. Also consider rechargeability, how many charge cycles you might need, and compatibility with your charger if you choose NiMH. This guide in 2025 focuses on these attributes to recommend the best AA options for common microphone use cases.
