CHEVY4X4BLAZER Posted February 28, 2012 Report Share Posted February 28, 2012 Hi guys I'm excited and just wanted to.let y'all know that I just purchased a D3400 for my truck!! Its replacing a stock battery and I'm curious as to what to expect from it. My current electrical is stock with only big 3 upgrade. My system is only 1200 rms at best for now. My current voltage drop is to the high 11s at full tilt. I'm hoping to also purchase an XP series battery during the SMD group buy. Quote Link to comment Share on other sites More sharing options...
Loslam Posted February 28, 2012 Report Share Posted February 28, 2012 That's a good battery to replace your stock, you'll probably only drop to mid 12s now. That being said only adding batteries if you're dropping pretty low is just adding more for the alternator to recharge. Still 1200 rms shouldn't be TOO hard on stock alt if you've got sufficient wires for your big 3, good luck Quote 1997 Chevrolet Silverado Extended Cab, 350 Vortec Things to come at some point...

The alternator is a 105 amp and its recently been warrantied thru autozone. It should do just fine for the time being. Quote Link to comment Share on other sites More sharing options...
Loslam Posted February 29, 2012 Report Share Posted February 29, 2012 Then you should be fine with that battery and stock 105 alt. Dropping to 11s seems a bit much. I'd check your wires and make sure you got some grounds to engine block or alt/bracket Quote 1997 Chevrolet Silverado Extended Cab, 350 Vortec Things to come at some point...

michigancapri92 Posted February 29, 2012 Report Share Posted February 29, 2012 I just ordeeedd my 3400 as well looking forward to it!!! Have you tried running a ground from amps in the back to up front that might help with voltage drop Quote Teamcapri.comThe TeamCapri 1992 Mercury Capri XR22012 FORD EDGE SQ BUILDOld build logMy FeedBack1992 Mercury capri XR2 Hyper LED Link to comment Share on other sites More sharing options...

Have you tried running a ground from amps in the back to up front that might help with voltage drop I think the main culprit is my battery because it is a bit on the older side. I've noticed that starting is a little weaker. I just replaced my starter. When I checked my voltage at the amp with the dmm, it's constant relative to checking voltage under the hood. So I think my grounds are pretty solid. Quote Link to comment Share on other sites More sharing options...
CHEVY4X4BLAZER Posted February 29, 2012 Author Report Share Posted February 29, 2012 Make sure you charge it before putting it in ⛽ My grandpa has an AGM charger that I will use to top off the battery. Quote Link to comment Share on other sites More sharing options...
CHEVY4X4BLAZER Posted March 6, 2012 Author Report Share Posted March 6, 2012 Just got it. Volt meter showed it resting at 12.7. I put it on the charger and it was 100% with 10 minutes . Is it OK to install as the primary battery now? Quote Link to comment Share on other sites More sharing options...
LoudBimmer Posted March 6, 2012 Report Share Posted March 6, 2012 My charger also says 100% charge after only 20min charge. But I leave it on charger for 1-2 days, it floats @ 13.3v and tops off the battery. Quote Link to comment Share on other sites More sharing options...
