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 ...
