battery

Hey everyone, I made the decision to replace my stock 5.0 intake manifold with the GT350 voodoo. I did this because I was having persistent P308-P306 misfires and I read the GT 350 manifold could potentially solve those issues (it did)! Unfortunately, now I have a new mix of error codes I’m...

So I’ve heard that the factory batteries in these cars weigh a ton, so I am looking for a good lightweight battery for my 2020 GT Premium 401a with the 10 speed. what are some good ones that don’t weigh much?

Hey! So I replaced my battery today and dropped one of the plastic cover screw things somewhere in the engine bay. I can’t find where it would’ve fallen and didn’t see it on the ground. I assume it’s going to fall out at some point while driving. Do I need to worry about it messing anything up ...

Hello, I've just ordered the following kit: OPT7 Aura Pro Underglow I was wondering if I could get advice from others who have installed underglow. I installed a flex strip set on another s550 mustang and hated the wire cable management. We also connected directly to battery which I knew was...

I’ve got my subwoofers working now but when they start hitting my voltage goes from 14.4 to 12.4, and when I’m driving it dips even lower and makes my whole radio and cluster flicker off and then back on. Would it not dip if I get a second battery to my amp or better for a 240 amp alternator.

Late 2016 model, is it normal for the battery of the car to run out after being parked for 2-3 weeks? I try get someone to turn it on and leave it at idle for 5-10 minutes or so every couple weeks when I’m on holiday but i always come back to a dead car. Others told me their germans don’t give...

Are any of you GT500 guys/gals using an Antigravity battery? I see they are fairly popular with the S550 platform. https://antigravitybatteries.com/products/starter-batteries/automotive/ag-h5-rs/ https://antigravitybatteries.com/products/starter-batteries/restart-oem/atx30-hd/...

Hi, I’ve got a 2016 GT, which I love, but if I go away for more than 2 weeks, the battery dies if I don’t disconnect it. Yet all the other cars I’ve had can be left for months… I’ve tried with and without alarm on, and no difference. Anyone else seen this?

Hey All, I want to make sure I have this right before storing the Shelby, as this is my first winter doing such. I still have the OEM bxt-99rt4-a battery installed, and recently purchased the Ford Performance batter maintainer found here ->...

Has anyone been able to fit the XS D4700 in their 2018+ Mustang? I heard it should fit without any modifications but I think that only applies to 2017 and lower models.

Hello! I have a 2018 gt350 with 20k mi So I got a charging system service now error, battery won’t charge, so I replaced it. Then the voltage won’t go above 14 v and drop to 13 when throttle hard. So I replaced alternator After reset bms, voltage is constant between 13.9 and 14.1 but I still...

So I am not very mechanical or knowledgeable about cars. This morning when going to work I hop in my car, push the clutch, and push my start button. The car then proceeds to make a rapid clicking and doesn't start. I tried a couple times and same result. The odd thing is that the infotainment...

I’ve owned my Mustang for only a few months, so please bear with me. Woke up this chilly am to a mostly-dead battery on my ‘19 Ecoboost Premium. Have not driven car in a week or so. Am charging the battery with my trusty Die Hard charger as we speak, but I got to thinking... Is this normal for...

I have a 2016 Ecoboost Premium. Now that fall is upon us and the weather is cooling down I like to sit in my car on my lunch break with the windows down. I roll the windows down, turn the car off, and turn the infotainment screen off to save power. It doesn't sit in power accessory mode, it's...
