The storage of the information has changed in macOS Monterey. Since I did not install Golden Chaos (too much for me), I adapted the script "blindly". Try it once with this:
use framework "Foundation"
use framework "IOBluetooth"
use scripting additions
set processInfo to current application's NSProcessInfo's processInfo()'s operatingSystemVersion() as record
set pairedNames to ((current application's IOBluetoothDevice's pairedDevices())'s valueForKey:"nameOrAddress") as list
set connectedValue to ((current application's IOBluetoothDevice's pairedDevices())'s valueForKey:"connected") as list
set connectedDeviceName to ""
repeat with i from 1 to count pairedNames
if item i of pairedNames contains "AirPods Pro" and item i of connectedValue = 1 then
set connectedDeviceName to item i of pairedNames
end if
end repeat
if connectedDeviceName ≠ "" then
if processInfo's majorVersion > 11 then
set xmlData to do shell script "system_profiler SPBluetoothDataType -xml"
set theData to ((current application's NSString's stringWithString:xmlData)'s dataUsingEncoding:(current application's NSUTF8StringEncoding))
set infoDict to (current application's NSPropertyListSerialization's propertyListWithData:theData options:0 format:(missing value) |error|:(missing value))
set devlist to ((infoDict's valueForKey:"_items")'s firstObject()'s firstObject()'s valueForKey:"devices_list")
repeat with j from 0 to (count of (devlist as list)) - 1
if (devlist's objectAtIndex:j)'s allKeys()'s firstObject() as text = connectedDeviceName then
set devDic to ((devlist's objectAtIndex:j)'s valueForKey:connectedDeviceName)
set batteryPercentLeft to (devDic's valueForKey:"device_batteryLevelLeft")
set batteryPercentRight to (devDic's valueForKey:"device_batteryLevelRight")
if batteryPercentLeft ≠ missing value and batteryPercentRight ≠ missing value then
set batteryPercentLeft to (batteryPercentLeft's substringToIndex:((batteryPercentLeft's |length| as integer) - 2)) as integer
set batteryPercentRight to (batteryPercentRight's substringToIndex:((batteryPercentRight's |length| as integer) - 2)) as integer
return "L: " & batteryPercentLeft & "% " & "R: " & batteryPercentRight & "%"
end if
end if
end repeat
return ""
else
set batteryLevelLeft to do shell script "BLUETOOTH_DEFAULTS=$(defaults read /Library/Preferences/com.apple.Bluetooth); SYSTEM_PROFILER=$(system_profiler SPBluetoothDataType); MAC_ADDR=$(grep -b2 \"Minor Type: Headphones\"<<<\"${SYSTEM_PROFILER}\"|awk '/Address/{print $3}'); CONNECTED=$(grep -ia6 \"${MAC_ADDR}\"<<<\"${SYSTEM_PROFILER}\"|awk '/Connected: Yes/{print 1}'); BLUETOOTH_DATA=$(grep -ia6 '\"'\"${MAC_ADDR}\"'\"'<<<\"${BLUETOOTH_DEFAULTS}\"); BATTERY_LEVELS=(\"BatteryPercentLeft\"); if [[ \"${CONNECTED}\" ]]; then for I in \"${BATTERY_LEVELS[@]}\"; do declare -x \"${I}\"=\"$(awk -v pat=\"${I}\" '$0~pat{gsub (\";\",\"\"); print $3 }'<<<\"${BLUETOOTH_DATA}\")\"; [[ ! -z \"${!I}\" ]] && OUTPUT=\"${OUTPUT}$(awk <<<\"${I}\")${!I}%\"; done; printf \"%s\" \"${OUTPUT}\"; else printf \"%s Not Connected\" \"${OUTPUT}\"; fi"

end ifIf it doesn't work, please post the current script once so I can possibly adjust it.
