Systems and methods relating to an analyte sensor system having a battery located within a disposable base

An analyte sensor system, comprising:

• a base configured to attach to a skin of a host, the base having a bottom side configured to face towards the skin of the host and a top side configured to face opposite the bottom side, the base comprising:
• an analyte sensor configured to generate a sensor signal indicative of an analyte concentration level of the host;
• a battery;
• a first plurality of contacts including a plurality of sensor contacts and a plurality of battery contacts;
• and
• a cover configured to secure to the bottom side of the base and secure the battery to the base;
• a sensor electronics module configured to releasably couple to the base, the sensor electronics module comprising:
• a facing surface configured to face the top side of the base;
• a second plurality of contacts on the facing surface and including a plurality of signal contacts and a plurality of power contacts, each of the plurality of signal contacts configured to make electrical contact with a respective one of the plurality of sensor contacts, and each of the plurality of power contacts configured to make electrical contact with a respective one of the plurality of battery contacts to provide power from the battery to the sensor electronics module;
• and
• a wireless transceiver configured to transmit a wireless signal based at least in part on the sensor signal;
• and
• a continuous sealing member configured to provide a seal between the facing surface and the base and around the plurality of signal contacts, the plurality of sensor contacts, the plurality of power contacts, and the plurality of battery contacts within a cavity when the sensor electronics module is releasably coupled to the base.
