Battery Configuration Versions

The Song Meter Mini 2 can be purchased with one of two options for battery power:

  • The Song Meter Mini 2 AA can run on either four or eight AA batteries. Alkaline batteries provide the most consistent performance, but other battery chemistries can be used. See Types of AA Batteries for more information.

  • The Song Meter Mini 2 Li-ion can run on between one and six 18650 lithium-ion (Li-ion) batteries. See Lithium-Ion Battery Requirements for details on choosing compatible batteries.

Note:

These are two separate versions of the Song Meter Mini 2. Neither version can be converted or reconfigured to use the other type of battery.

The type of battery used significantly affects deployment time. As a general rule, 18650 lithium-ion batteries hold significantly more energy than AA batteries, and they are, by definition, rechargeable. Using six, high-quality 18650 lithium-ion batteries will enable the longest possible deployments with the Song Meter Mini 2.

Other than the differences in battery compatibility, the AA and Li-ion versions of the Song Meter Mini 2 are identical in functionality.

Important:

Lithium-ion batteries are not to be confused with Energizer® Ultimate Lithium™ (lithium/iron disulfide) batteries.

18650 lithium-ion batteries are larger and put out a much higher voltage than all types of AA batteries. 18650 lithium-ion batteries therefore cannot be used interchangeably with any AA battery.
