battery??

So my 98 sport 4.0 drove just fine at lunch. Got back to the shop and forgot to turn off the lights. went to start it after work and of course the battery was dead. so I hooked up some jumper cables to my uncle's Jeep and probably didn't wait long enough but tried to start it anyway. it cranked a couple of times and then quit. so he upped the RPMs on his Jeep to get mine to charge a little quicker . but after about a minute I tried to start it again and nothing happened. so I got out to check the cables to make sure they had a good connection, got back in and turned the key. this time it just set there and cranked and cranked. I had to give it some gas to get going. the problem is, it wouldn't stay running unless I kept my foot on the gas. it was raining out and he had somewhere to go and that was my one chance for a ride so he took me home. just wondering if this could be because I didn't let it charge enough? I didn't think that once it got running that the battery would have an effect on it like that??. So my question is, is this because the batteries dead and won't keep it running or is it possibly something else??

If the battery is completely dead you'll have to wait a few. The 4.0 engine has to have a minimum voltage to run. It's injection and ignition system draws a lot of juice. Charge the battery. Then try again.

I agree. Take it to AutoZone or Napa and have them charge it and test it.

Taking the battery down to zero with the lights left on normally sounds the death knell bells. Batteries never fully recover after that, they won't hold a charge as long and they'll die more easily.

I'd start thinking about a new battery, and while not cheap, it's real hard to beat the Sears Diehard Platinum which is made for them by Odyssey. It's an AGM battery which simply means it's a more rugged and longer-lasting battery.

It put the final nail in the coffin of my last battery. I have an AGM battery now. Not the sears, but 750 CCA and deep draw. Hoping it will handle the extra lights, CB, and winch. At least that is why I bought it.

Yes, that is typical for a very dead battery. It takes a while for the electrical system to reach a steady state because the battery is not providing a strong voltage to the alternator.
