It is recommended that the Mark 2 unit be cleaned before storage. To extend the battery life of the Mark 2, you need to charge it to about 80% (shows 4 blue indicators) before storing it. If your storage time is more than 6 months, it is recommended to check the remaining charge every 6 months and charge to 80% when it is below 20%(shows 1 blue indicator). We have designed a perfect size bag for the ZERO BREEZE Mark 2 air conditioner and its accessories. If you are interested, please contact customer service. support@zerobreeze.com Never store your air conditioner on its side, as this can damage it. It’s best to store the AC unit in an area that is cool and dry.
