Our E350 rig is kept in a heated garage. I have to disconnect the battery or the E350 will significantly drain it after a month. If I waited two months, it would not start our rig. If I waited six months connected, our battery would be dead as a door nail, unlikely able to bring it back to a reliable state.

Even though they are designed to handle the amperage, they have a much higher failure rate than if it was not there to begin with. It is much better to disconnect the negative ground terminal on the battery post, especially if doing it just once a year during the "Off" season.CodyClassB wrote:Is that the one from HF, if so that green knob on mine loosed up and caused arching, the black burned contacts left me with a no start situation twice before I finally remove it. Now I just disconnect the neg terminal when in storage. As others have said there is a parasitic load, mine is about .4 amps which will drain your battery. I charged mine in Oct and disconnected after almost 6 months it is still at 80% SOC.
Thank you all. I learned my lesson. I recharged the dead battery using the method mentioned above (jump started and recharge) . I also also install the Terminal Quick Disconnect Switch

will this cheap one charge ?

Thanks all . I updated the question. Since modern chargers do not charge completely dead batteries, will this cheap one charge ?

Modern battery chargers will NOT charge and absolutely DEAD battery. Jump start it, hold fast idle for about 10 minutes, shutdown and immediately connect the charger.
Just jump, attach charger, start charging, remove the jump and let it rip.
For the OP: if you are plugged in or have solar you can add a Trik-L-Start combiner to keep the chassis battery charged. Letting any battery run that low will cause sulfation and permanent loss of capacity.
