Answers.Body: <p>I deployed 55 audiomoths for roughly 3 months total in the tropics, both dry and wet seasons, and lost 3 to battery corrosion, 1 to a broken switch. Wet season means daily serious downpours. I also had 14 of the waterproof acoustic vent stickers on the weatherproof cases get ripped (mostly by ants), so those needed replacing. One of the case latch mechanisms broke.</p>

Body: <p>I'm deploying audiomoths for a contract (weatherproof cases, 3 months of continuous deployment per year). I need to factor in a reasonable cost to cover moth replacement but I'm not sure how long I can expect them to keep working. Can anyone please share their experiences regarding failure rates, rates of replacement for parts and ideal deployment lifespan of our little green friends.</p>

Comments.Text: I'd be happy for any information whatsoever regarding failure rates (moths, cases, noise filters, uSD). For additional context: I deploy for 12-14 weeks at a time, once a year in austral spring/summer. This includes infrequent low volume rainfall events and high daily temperatures. I record two 5-minute recordings each day of deployment at 48 kHz with medium gain (my Nyquist rate is about 16). During the last deployment I lost 10-20% of my audio filters (due to birds or insects). Some filters were destroyed entirely, others just had a pinhole and need replacing.

Comments.Text: About 8% of the units had incursion of water following damage to the filter. I lost recordings but all units still appeared to be working when tested. These deployments only require 1 set of batteries.
