I have a 2005 F350 DRW with 92k miles. It has had a hard time starting the last few days with temps here in Kentucky in the mid-20s. I added some fuel additive but battery still required jump to start today. Do I need new batteries and if so what would you recommend? Make? Any other cold weather start tips are appreciated!
Thanks!

 

Welcome to FTE

Yes Get New Batterys Low battery voltage will Kill the ficm Fast

also Clean all the connections at batterys and follow the 2 main battery grounds and clean those too and check the Alternator output should be putting out 13.6-14.3 volts after 2 minutes when the GP turn off

Best to keep the charging system upto 100% on these 6.0 or some of the other electronics will be Taken out

 

Thanks Benny!

 

You Got It!!
