SnowDrifter Posted March 2, 2013 Report Share Posted March 2, 2013 Good video. So many people think they need isolators without understanding why. The fact of the matter is: most people don't. And the only folks who benefit from it are, as you mentioned, people who play for extended periods with the car off. Like at an indoor show or something 1 Quote ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...

Like at an indoor show or something what about keeping a wet cell battery upfront to start the car and run maybe a 4 channel on it and a bank of AGM's in the back for the sub amps (cheaper than buying a AGM for upfront) Quote down rpping vanderbilt. 30 miles from victoria. i own the 3rd loudest setup here out of 3. but i did put together all 3 setups ^^ Cant wait to swalllow Ghost's babies Link to comment Share on other sites More sharing options...

Just get an AGM for the front. I know you might be on a budget, but find another way. Consider the cost of an isolator vs. selling your front battery and buying an AGM. Or either downsizing or eliminating the rear battery altogether 3 Quote ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...

Or either downsizing or eliminating the rear battery altogether yeah true lol im not saying its for me personally im just saying it might help people on a budget and selling a wet cell isnt gonna profit much more than like 50 bucks depending on how old it is Quote down rpping vanderbilt. 30 miles from victoria. i own the 3rd loudest setup here out of 3. but i did put together all 3 setups ^^ Cant wait to swalllow Ghost's babies Link to comment Share on other sites More sharing options...

-X-RaTeD- Posted March 23, 2013 Report Share Posted March 23, 2013 (edited) So, AGM batteries don't have "cells" that die in the same sense of a wet cell battery? I heard that you shouldn't mix the types because if one of the 6 2V wet cells dies, then it's now essentially 10V battery, and the alt will overcharge the 12V agm battery connected in parallel without an isolator.

meade916 Posted May 31, 2013 Report Share Posted May 31, 2013 the only problem i have with isolators is that sure, you just killed one of your batteries... and now, you can start the car on the other battery, (that is still good).....but now, you have an alternator trying to charge a dead battery. That is one of the worst things you can do to an alternator is charge a dead battery back up with it. The best thing you can do is just not play your system for extended periods of time with the car not running. Start it up once in a while and don't kill the battery to begin with.

If you have a dead battery, you need to replace it. Not bandaid the problem lol. And the alt won't overcharge it. It will drain your voltage of your good battery leaving you with 2 dead batts Quote ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
