Xdq_21X Posted November 6, 2016 Report Share Posted November 6, 2016 I want to add a second battery in the trunk, my question is do my 2 batteries have to match each other? The battery under the hood is stock but I want to add a bigger one in the trunk...is that going to be okay? Or what?? Link to comment Share on other sites More sharing options...
reedal Posted November 6, 2016 Report Share Posted November 6, 2016 as long as they have the same resting voltage, it is fine.

Wishuponasub Posted November 6, 2016 Report Share Posted November 6, 2016 Yes that's perfectly fine. You just don't want to mix types of batteries. For example If you have a regular lead acid battery up front you don't want to put an AGM batt in the back or vice versa.

Tomas Vega Posted November 18, 2016 Report Share Posted November 18, 2016 Can I ask a question how about if I have 1 Xs power d2400 up front to turn on the vehicle and 2 xp3000 will it damage each other or is that Not a good mix of batteries or should I as a isolator Link to comment Share on other sites More sharing options...

They're all AGM.

SkarredSierra Posted November 18, 2016 Report Share Posted November 18, 2016 Ive ran with a lead acid up front and an agm in the rear for almost 4 years. No issues. And no isolater. Link to comment Share on other sites More sharing options...
reedal Posted November 18, 2016 Report Share Posted November 18, 2016 the only issue that could come from mixing regular lead-acid and AGM is the difference in resting voltage and lifespan. whichever is the weaker of the two upon connection, that one will leach off of the other until they are at equal voltage. which is typically only less than or equal two .2vdc SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...
