I ran the biggest one Costco sells. Lasted under 3 years. Just died one day the weather changed and wouldn't take a charge. Deep cycle won't hold up to starting and running chores. They are designed to be run into the ground and then charged back up.
Well the reason why i am wondering is because i have something draining the life out my battery over night (Think its the body ground controller) And i have an old deepcell in my camper and i been thinking about using it because it can handle the draining that is happening so i don't ruin the battery i have in the Heep right now.....
Like i said i got it just siting here doing nothing atleast it will stand up to it while i try and sort out that problem. its my DD so i can't just like it be down i still have to drive it.. Right now i got the #7 fuse pulled and its not draining it...
Tossing in a side note about batteries. I know one day this will haunt me, perhaps in the morning, however in 2003 I picked up a battery from Advance Auto Parts for my Subaru, 3 year pro rate, etc. I tend to use the car radio when I am outside working alot, and this has become a sick project. I still have that same battery today. No maintenance since then, the thing just works, it was the cheapest battery they had at the time, and although only starting a small turbo 4 cylinder, I am going to keep this thing until it does finally die one day. Passes the load test every service.
1996 ZJ - That 2nd Oxygen sensor, yeah some serious butt connectors and heat shrink there, how is that for off road modification! - Still stock.
Okay i got another Alt from the junkyard i didn't change the pully (Just one less rib) I just put it on to test wasn't leaving it on long enough to damage anything and when i ran it my mulitimeter showed the battery was getting the same voltage as with the other Alt. around 13.2V so i swap the alt's again putting the old one back on and i drive to the store going i had everything off and the gauge needle was near 14V but still below it so i get to the store shut it off and go in when i lefti turn on my radio, AC, headlights on with fog lights and my cooling fan now going down the road doing 65 i watched as my battery gauge starts dropping and i keep on like that and when i get home i pop the hood and hook my MM to the battery to see how many volts its getting and it was at 12something and so i turn everything off but leave it running and its back up but only 13.3V am i right in thinking my Alt is bad and the people at advance that tested it is just wrong? below is some show and tell. lol
If they are fine then why is it if i drive to town 10miles with just the AC on pull up to a gas pump leaving it running start pumping gas and it dies and i go to start it right back up the battery is too weak to start it but if i repeat with the AC off it will sit there and idle while pumping with no problems or even shut it off it starts right back as strong as can be????
