Battle of the Batteries

We put three battery brands to the test to see which would last the longest in Loggerhead's passive acoustic recorders.

The Test

One pack of 3 D-cells for each brand

Record 60s

Sleep 60s

96 kHz sample rate

Amazon Basics was the winner, running for 26 days, whereas Energizer lasted only 20 days. Sorry Energizer bunny.

In summary, using Amazon Basics alkaline batteries with a 50% duty cycle:

Snap would run 26 days

LS1 would run 104 days

LS1X would run 208 days
