Can you guys help me with a technical question? I rarely use my Jeep during the week. Based on this fact, I disconnect the battery terminal until I plan on using the car. Is this doing any damage to the computer system? Would I be better off with a battery tender?

I hear some people say that it is bad to leave the battery disconnected, but I have been doing it for two years without any problems.

Thanks in advance!

If you drive it at least once a week I don't think you would need to anything.

When leaving a vehicle sit more than a month, I use a Battery Tender.

i use a battery tender. like you, my jeep isnt used all the time, esp in the winter. I have been using the tender for almost 3 years now without an issue.

read all the battery threads here. lots dont mkae it 3 years with the OEM. the tender will prolong that battery life. and if you hard wire it to the battery and poke the connection thru the grill like I did it takes all of 30 seconds to connect and disconnect the tender.

I use one on my Cobra, my last battery lasted 7 years and was probably driven less than 1000 miles. My Jeep is still on the original battery and I have had it since Aug. 06 and have never had it on a charger and has gone weeks(2-3) without being on one and has never not started.

Thanks for the responses. Do you think I am hurting the battery or system by disconnnecting the terminal?

I highly doubt it.

Spend the little money on a tender. you can't go wrong and you'll find yourself using it on everyhting else with a battery too.

Doesn't the radio lose its time setting when the battery is disconected for so long?

i love my battery tender. i dont drive my truck allot at all. it wont kill u to not use one if u take it out on the wekends. if ur gonna let it sit more then 2 weeks or more at a time i deff would say to get one. especiaslly if its and older jeep. not that an 06 07 08 or 09 is that old but u know what i mean.

fyi they have those little mem holders that u put a 9v battery in and plug into the cig lighter anytime u do work to the truck so when u disconnect the bat u dont loose all ur radio settings and time.

No, the radio settings stay the same. I dont think it does any damage, but some people scare me that the computer will act funky.

On a side note, what do you recommend as a battery tender?
Thanks

+1 on using a battery tender for anything that sits more than 2 wks. The make is literally 'Battery Tender'... Just google search... they are running about $46. The best part is you can hook up a permanent connector to the battery and run the quick disconnect end to a spot in the grill or other out of the way area to make hooking up the tender a 2 second job... you don't even need to pop the hood. Its similar to a 2 connector trailer connector.

But having said that... if you are driving it at least every 10days or so... you probably don't need it. Certainly doesn't hurt though.

deltran battery tenders is the way to go. should be able to get them off ebay or batteries plus carries them. i have been living and working overseas for two and years and come home maybe twice a year. with a cummins and three srt's sitting in a garage, i've never had a issue with my batteries. my buddy is suppose to start them monthly but who really knows.
