XS Power D6500 3800 Amp AGM Battery with M6 Terminal Hardware - 12 Volt 86Ah 1100CA Deep Cycle AGM Powercell for Car Audio Systems or Electronics - 53.81 lbs, Maintenance Free, Sealed Design

I bought my first set for my Excursion 7.3 Diesel in May 2015 I am so mad LOL just kidding One of the two just died Aug 2022 Over 7 YEARS !!! Outstanding and only one of the two died. I always replace in set though. Great batteries this truck kills every other battery in two years or less..... Great Job XS Power

I use this battery to power a winch and it makes my winch a super winch. I do charge it with a smart charger prior to taking the truck out to to mud pits. It gets used on heavy loads and doesn’t even flinch. Great battery.

Strong out of the box, dropped it into my truck to improve both starting performance as well as audio quality, and achieved both. The engine cranks and start somewhere between 2x and 3x faster compared to the heavy duty Interstate battery that it replaced. Also the high available amperage output has stopped my headlights/gauges from dimming, especially on hard, sharp bass kick drum hits. Running approximately 1,500 Watts on the stock alternator.

Battery worked perfectly when first purchased, but the lifespan of it is short for a $400 battery, and the warranty is only one year. Mine went out, and Amazon or the seller could not help.

Purchased this to install in my 2006 Lincoln Towncar to pair with a 250 amp alternator & big 3 kit. My 2 CompVR kicker 12s are hitting very very hard and i have more tha enough power to add 2 more 12s. I also installed 5 tv screens and LED lights everywhere. Since the install, MY LIGHTS HAVE NOT FLICKERED ONCE!!! Plus the car runs so much better. This battery is a beast and a must buy if you need serious power for custom audio.

Excellent, excellent and excellent. I recommend using the actually XS Power battery website to find the right battery for your engine bay. Battery does more then what they test it for. Excellent.

This battery is a POWER GRID.. with my new 0 gauge wire kit , it has more than enough power to get my 2 HDS208-D2's and all my custom MOREL and DAYTON drivers running on a DIAMOND AUDIO 900 + HIFONICS ZRX2146 mono > in my F150 hittin smoooth and HAAARD >lights on >AC on high makes no difference .... going for the MECHMAN ALT next... the Interstate batt I had before had a lot of trouble keeping up and often needed charging overnight... Highly recommended but pricey.... also a big +++ to MOREL speakers > if you want total SQ check it - if you want what everyone else has be prepared to settle for less...

This is the battery powers like none other Ive ever useed before. Ive used optima and kenetil and this battery is on a whole new level. This thing is powering three amps and does it flawlessly. Light dont dim and there is no power loss inside the car at all. When I tell people about what Im using to power my system, their mouths drop. Recomend this one or the 7500 if you are looking for pure and absolute power.
