Batch script to evaulate battery life and take action

I'm having trouble getting this script to work. My plan is to take one course of action if battery life is less than 50% and take another action for battery life is 50% or higher.

set CRITICALLEVEL=50
for /f "skip=1" %%a in ('wmic path Win32_Battery get EstimatedChargeRemaining') do if %%a gtr 0 set BATTERYLEVEL=%%a
if %BATTERYLEVEL% leq %CRITICALLEVEL% goto CRITICAL if %BATTERYLEVEL% gtr %NOPOWERLEVEL% goto UPDATEFIRMWARE


:UPDATEFIRMWARE
Echo Firmware about to install
Echo Battery life is at %BATTERYLEVEL%
goto eof

:CRITICAL
Echo Battery is too low to update
Echo Battery life is at %BATTERYLEVEL%

:EOF
Echo Done

Any help here would be great.

Something like this?
@echo off
setlocal
set CriticalLevel=50
set BatteryLevel=-1
for /f %%a in ('wmic.exe path Win32_Battery get EstimatedChargeRemaining ^| findstr.exe /r "[0-9][0-9]*"') do set BatteryLevel=%%a
if "%BatteryLevel%"=="-1" (
	echo No battery found; keep the machine plugged in.
	goto UpdateFirmware
)
echo Battery level is at %BatteryLevel%%%.
if %BatteryLevel% leq %CriticalLevel% (
	echo Battery level is less than %CriticalLevel%, so too low to update.
	pause
	goto :eof
)
:UpdateFirmware
echo Firmware is about to install ...
