XS Power D4800

XS Power - Perfect solution again

The shipping was super fast (3 days I believe) - perfectly packaged

battery showed up with 12.5v - charged battery with CTEK battery charger for AGM batteries (took about 8 hours)

My second XS Power battery ( first one was in a different vehicle ). This replaced my factory battery which seemed to be failing after only a year and a half on a 2013 vehicle. I am a car audio technician MECP Advanced certified and did measurements with my Fluke meter before and after changing the battery. My problem was corrected and XS Power lives up to the quality of my first D3100 battery in the other car.

disclaimer: my results are not solely due to the battery, but the battery was the main component in a failing electrical system. my voltage was starting to dip slightly then spike to over 14.9 up to 15.7 giving me high voltage warnings.

system specs:
-stock 160 amp alternator
-900 watts rms of audio system power
-big 3 upgraded with knukonceptz true copper 0ga wires and multiple
kicker 4ga runs from battery
-1 farad cap 3 inches from subwoofer amplifier
-voltage stays steady above 14v at all times (tested from inside vehicle) while system is running and headlights on (no dimming)
-voltage now stays between 14v and 14.7v
-negligible voltage drop front to rear (off and idle)

Amazing battery!

I bought this battery to function as my main power supply and it did not disappoint. I have it in a 08 c300 Mercedes powering a sundown audio SAZ1500D with a single Sundown ZV3 12. My original battery would make my dash and lights dim when the bass hit even while driving. I can leave my car off and still slam with absolutely no dimming with this D4800. I would definitely recommend and buy again! Not to mention the quality and look is really good, if only this bad boy wasn't hidden in my holod under a cover.

Good product

I'm using this battery to operate my system and so far it has been great I would recommend this to anyone

King of batteries...

I compared many batteries & the one that had the best quality was XS. I have it hooked up to an 07 Yukon and my voltage is always a constant 14V. My system sounds real clean and deep.Sonic has the lowest prices for XS batteries...if looking for one buy from them.

WOW

WOW IS ALL I CAN SAY ABOUT THIS D4800. I BOUGHT THE 240 AMP ALTINATOR WITH THIS BATTERY AND MAN IT PUTS OUT SOME MAJOR POWER TO MY SYSTEM. THEY ARE RUNNING MY 2 BELVA BB3000D AMPS ALONG WITH 2 AUTOTEK MEAN MACHINE M1400.4 AMPS. 8 PIONEER 6X9 ALONG WITH 4 PYRAMID TW46 TWEETERS. 2 15 INCH CERWIN VEGA VMAX 1400 WAT RMS IN A PORTED BOX.. MY DODGE MAGNUM LOOKS LIKE IT IS BREATHING.. ALREADY BUSTED ONE WINDOW. SO NOW I HAVE TO KEEP MY WINDOWS DOWN ... THANK YOU TEAM SONIC FOR ALL YOU HELP... WILL BE DOING MY DAUGHTERS CAR NEXT .

Very good

This product very good for support in my car and complete for my audio car (about 3000 w)

Great buy!

I am running this as a secondary battery to my D6500 under the hood and it definitely does the trick.. Even with stock alternator I don't drop much voltage! Xs power is the way to go if you want the best power supply!

Awesome

Awesome product. Punches alot of juice out. I'll be buying another.

best battery on the market xs power

This battery is very strong I'm using it in my 2006 Chrysler 300 as a replacement factory battery and I have a XS power XP 3000 to go on with the D 4800 and my voltage stays at 13.5with a 4k amp so I would recommend The d 4800 as a factory replacement or secondary battery is very strong XS Power for the win
