BassMunky Posted March 3, 2019 Report Share Posted March 3, 2019 So when I changed out alt and new batteries it would charge at 14.8 it been about 3yrs now. And the voltage reads at 14.5 to 14.4 what causes it to be lower and is that the alt or the battery going out? 2006 tacoma new OEM alt with 2 group 31 duracell agm battery.

Ron36 Posted March 3, 2019 Report Share Posted March 3, 2019 Is the weather any different, when it’s cold I charge 15.1-15.3 and when it’s hot 14.6-14.9 . It’s all normal. 2022 Ford Maverick on 22’s Skar SK1500.1 on 4 Skar VD-8’s Mids Sundown Super tweeters, Skar TX 6.5 components on Skar SKM400.4 LC2 for audio control , XS Power D680 XS Series Extra Battery Link to comment Share on other sites More sharing options...
slowfkncar Posted March 3, 2019 Report Share Posted March 3, 2019 Are you reading directly off the battery terminal? Link to comment Share on other sites More sharing options...
Dragonsyph Posted March 3, 2019 Report Share Posted March 3, 2019 Like others have said, the COLDER it is the higher voltage it will charge at. Most battery chargers do the same thing and when put in COLD charge mode they charge at a higher voltage also. ♦ 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 Link to comment Share on other sites More sharing options...
