Help, emissions readiness monitors

Alright, I've been on here a while but haven't said or done much, I need help though. It's time for an inspection and my emissions readiness monitors aren't ready. I understand the gist of what they are, but they won't ready. I've put about 400 miles on it since it was last worked on. I've used my code reader after driving for a while and certain ones will be ready, but when I cut the Jeep off and restart it, the four of them aren't ready again. On top of all that, I'm trying to sell this Jeep as soon as possible. I think it might be the battery. It struggles to start when cold, so I figure the battery might not have the voltage it needs and the computer basically resets every time the Jeep is off. The guy at Advance (not necessarily a guru) said he knows of chryslers in particular having computer issues. I haven't heard anything about this being tied to a computer issue before, but maybe I'm wrong. Any help is great, thanks.

It's a 2004 Jeep Wrangler Rubicon with an automatic transmission, lift kit and all that cool stuff.

Clean your battery terminals and cable ends until they shine. Then when you put it back together make sure the connections are very tight. It sounds like you are losing battery feed when it sits and that's resetting emissions monitors. It also means when you try to start you have a weak connection and so the starter struggles to pull enough power.

Battery terminals were the issue, once they were cleaned the monitors were ready within an hour and it was inspected. Thanks for all the help.
