Isolator or solenoid?

Both of them have strenghts and weaknesses. I was wondering you guys think.Tell the Snap-On guy I'm not here!

Solenoid, although I refer to them as an Isolator. Top Secret, I can tell you but then my wife will kill me.

Isolator vs. Solenoid? Apples vs. Oranges.

ummm you have 2 batteries.... you perfer to isolate them with fruit?Tell the Snap-On guy I'm not here!

Indeed but I find that a pomagrant usually preforms the best. To be fair there are door popper solenoids as well as what you are talking about so being that your question was fairly vague I can see where the confussion came from.  I have always used isolators and never had an issue with them so I guess I subscribed to the "If it aint broke dont fix it" line of thinkingdouble-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

Thanks ravendarat for clearing that up. The reason I ask is because I've witnessed 1 go bad. And then I worked at a shop which only installed solenoids. That one experiance kinda haunts me and I'm looking for some emotional support for trying them again. Tell the Snap-On guy I'm not here!

I never use any kind of battery isolation... I have also NEVER had even the first problem in NOT using isolation, either. Waste of power (sure, a small amount of power), more parts to go bad, additional connections to eventually fail... Should I go on? Why bother? Do it right without the isolator, and never lose any sleep... It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

However if you use an isolator and you use the stereo for extended periods of time without having the vehicle running, you can be sure that you will be able to drive away in the enddouble-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

The best answer to that? Don't *DO* that... It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

DUDE!!! This was exactly what I wanted to talk about!!!! I soooo want to know how safe it is to not use an isolator. So I can just parallel a second battery and be safe? I know how the battery damage can happen but I plan to use 2 optimas.Tell the Snap-On guy I'm not here!
