The CR2450 coin cell batteries found in SmartThings Multipurpose Door Contact Sensor and other smarthome sensors only last 1 year or less. The CR2450 battery in my outdoor multipurpose sensor only lasted about 6 months because it is constantly reporting the temperature.

Rechargeable CR2450 compatible coin cell batteries are available and known as LIR2450. You will also need a special coin cell lithium-ion charger. The kit I bought includes 4 LIR2450 batteries and one charger that can charge 4 batteries at once, and can also charge other sizes of coin cell lithium-ion batteries.

▼ NOTE that this battery did not work in the Chamberlain MyQ Garage Door sensor, which is unusual. It seems that the sensor is more sensitive to battery voltage, and shuts down due to the higher voltage of these rechargeable cells.

The normal charge cut off for Li ion batteries is 4.2V, so that is normal for the battery to reach that. When a load is put on it, it will drop rapidly to 3.7V nominal. I found that they work fine in Smarthome products, but did not work in MyQ garage door sensor. It didn't damage the sensor, but the sensor would not work while the battery was in due to the higher voltage. A controlled discharge tool can be used to discharge to a specific voltage, like this - https://amzn.to/3LRZAa4
