EM300-MCS/EM300-SLD battery payload missing

[peternmuller]

When getting payload data from EM300-MCS/EM300-SLD sensors, there is no battery information. I saw that in the code, there is a function to decode battery, though.
I tried with the correct payload decoder for each sensors, but still no data.

Here's what I get for the EM300-MCS:

temperature: 21.9
humidity: 53.5
magnet_status: "close"

For the EM300-SLD:

temperature: 21.1
humidity: 54.5
leakage_status: "normal"

I also tested with the EM320-TH sensor, and this time it reports the battery as expected:

battery: 100
temperature: 23.8
humidity: 39

I also tried walking through the MIB, and there is no battery for EM300-MCS/EM300-SLD sensors:

iso.3.6.1.2.1.47.1.1.1.1.7.2200 = STRING: "2001 Temperature"
iso.3.6.1.2.1.47.1.1.1.1.7.2201 = STRING: "2001 Humidity"
iso.3.6.1.2.1.47.1.1.1.1.7.2202 = STRING: "2001 Leak"
iso.3.6.1.2.1.47.1.1.1.1.7.2300 = STRING: "1745 Temperature"
iso.3.6.1.2.1.47.1.1.1.1.7.2301 = STRING: "1745 Humidity"
iso.3.6.1.2.1.47.1.1.1.1.7.2304 = STRING: "1745 Magnet"

Didn't touch it for about an hour, the EM300-MCS started reporting battery stats, but the issue with EM300-SLD still persists.
