I haven't started my car up in about 3 months. Now the battery us dead. Probably just gonna buy a new battery. The question is when you guys let your car sit do you disconnect the battery and if so do you disconnect the negative, positive, or both?
I use a trickle charger.

Could do that too. They make cool terminal ends that attach to the posts (like normal) but have a attachment that the cable goes on, which is held down by wing nuts. So instead of always reaching for a box-end and a ratchet, worrying about cracking terminal ends or stripping/rounding bolts... You just turn the wing nut and safely tuck the cable to the side.Just disconnect the negative terminal. I have been doing it forever now and have had my batteries last longer than any of them should have.
Okay not only is that how you damage batteries, but it's how you kill alternators as well as risk electrical components. You know the battery charger is exponentially more dangerous than a battery tender right? Some models have "Jump Start" features that have enough power to short out a cars electrical components. Even with a battery out of a car (how i charge a battery when not using tender) I charge it far away from the house.A second vote for trying to charge it. Put your charger on auto mode and let it go for a handful of hours.
Battery tenders are popular, but I don’t use them. I don’t want to leave anything plugged in and charging while I am out of town for work. I either take the cars for an errand run periodically or hook up my battery charger occasionally when I’m playing in the garage.
For the past 5 years I've use a Tender on my Optima when not driving the car, always. If the car wasn't being driven I removed the ground to the battery and connected the Tender.... Every night. Doing this method STILL requires me to replace the Optima battery every 2.5 years..AARRGGG. I'm on my third battery in 6 years which is Complete BS...$$$$

Why go with Optima? The OEM batteries last 10+ years.
