Dragonsyph Posted March 6, 2019 Report Posted March 6, 2019 Most battery’s are rated to be dead at 12v and have testing of around 12.9 so at 12.3 that’s almost dead lol, if those resting voltage are after charging them I’d say both battery’s are bad or going bad. Not sure if dif brands have dif resting voltages so it could be different. ♦ Sundown NSV4 18" + Sundown SALT-4 Baby ♦ MechMan Elite 370a + XS3100 - XP3000 ♦ SHCA 1/0 OFC(blue) + SMD Fuse Holders(blue) ♦ Pioneer AVH-2440NEX + SHCA Pro RCA
Joshdashef Posted March 6, 2019 Report Posted March 6, 2019 XS recommends 12v batteries stay above 12.6 so 12.3 is in bad water depending on the brand SMD Tool Map (2024): https://www.stevemeadedesigns.com/board/topic/226545-smd-tool-map-2024/ Great Box Bracing Examples: https://www.stevemeadedesigns.com/board/topic/202148-best-way-to-brace-a-box/?do=findComment&comment=3055002

BassMunky Posted March 6, 2019 Author Report Posted March 6, 2019 How you recondition? Desulphate? Shakin not Stirred....my buildhttp://www.stevemead...ngle-cab-build/412 CVX And put a sealed enclosure in your trunk cut a hole in your deck and call it ported
reedal Posted March 6, 2019 Report Posted March 6, 2019 Select battery type (agm) place in charge mode, when charge is complete it will automatically go into maintain mode (pulsing green LED). *If the charger has to provide its maximum maintain current for a continuous 12 hour period, it will go into abort mode (see Aborted Charge section)* Leave it in maintain for a day, then remove charger for a day, then check battery resting voltage with a multimeter 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

Should I get a ctek charger? Those can directly choose desulphate.
