XS Power D3400 XS Series 12V 3,300 Amp AGM High Output Battery with M6 Terminal Bolt

good ass battery.

XS POWER D3400!!! Holy Moly power batman! This battery is awesome. If you’re in the market to buy a battery, wether its for upgrading your sound system or to simply replace your old battery, then this is it. Is it pricey, is it going to last 10+ years, is it a direct fit, or is it durable, HELL YEAH!! Since 2003, I had an Optima yellow top in my IS300 and had to replace it once with another Optima yellow top and I’ve had enough. Replacing a yellow top every 6 years at $200+ a pop… it’s not worth it anymore. I’ve read somewhere that these things will last 10 years no problem, well I’ll see about that. Still skeptical. This bad boy is hefty! It bolts right on like a champ. It comes with the M6 terminal bolt and you can bolt things right up. It does NOT come with battery posts, but can be purchased separately. Some may think this is a bad thing, but it really isn’t since your old battery terminal has a top mounted bolt, simply remove your cables from that bolt and mount it directly to the battery. Since you’re battery is coming out anyways, I’d recommend running a parasitic battery draw test with a meter. Google “parasitic battery draw”. This thing fires up real quick! I think it comes close to doubling up on the CC amps on my IS300. So my car starts right up. Heavy duty for sure, I’ve ran my radio with my car off with an eD nine-4 with DLS Nordica 6.5s and a Audioque d1200 with an Acoustic Elegance ib15, and this thing rocks and after an hour my car started right up.

I have a small SUV (2005 Escape) that I use to do a ton of the grid camping. This battery perform solidly year round and never complained about me needing to steal it's power to run other overnight accessories: included running a power inverter and operating/charging multiple laptops or a fan that has a really high power on draw. The vehicle could remain parked in below freezing temperature for weeks at a time and have no problems. NOTE: I REALLY was tempted to give this a 4 star rating as almost 3 years to the date, this battery died. I purchased the battery January 2016. Leading into winter of 2018, I noticed the vehicle starts were slowing down. Alas the vehicle was out of commission over the winter (end of November) and was not started for 3-4 months (beginning of March); at which point the battery was so dead there was no reviving it (tried charging, but seems there were several cell outs, it never could reach over 12v). So, I know the battery was starting to get a bit tired, but I can't say for sure how much life it really had left (3-4 months with weeks at below freezing could have zapped any stalwart battery)...

The battery was immediately shipped and has a fresh manufacture date. This was the cheapest price that I have found anywhere.

Super clean look , easy to install… perfect fit , don’t forget to buy adapters for side post applications

Well this was initally 5 star review, I loved it when I got it (December 2023). Worked great with my big cam supercharged car, started instantly and worked perfect for months until today (5/28/24). Went to start it and the car turned over for a few seconds then nothing, I figured I knocked a ground out or something since the car shakes with the cam, checked all the wiring and nope everything is fine. Put a meter on the battery and it's dead so I put my AGM charger on it, wouldn't hold a charge, I jumped it and it started, drove it to try and get some charge but when I shut it off and turned it back on it was completely dead again. Had a load test done and it came back as bad battery, contacted XS Power and said since I bought it through Amazon, they couldn't do anything thing. So basically I have a $400 paper weight, looks like I'll be headed back to SuperStart Walmart batteries.

If you’re like me and run car stereo equipment, this battery is a must-have — just make sure you use a battery isolator. This XS Power D3400 3300 Amp AGM Battery is a beast. It completely stops your dome light and headlights from dimming, even under heavy load. You can hook it up to another car with jumper cables, and they can start their vehicle immediately — no waiting. I’ve ordered this battery three times for different setups, and it never disappoints. Highly recommend it, especially if you’re a bass head like me.

Holds charge well, came in good condition and weight is accurate as well.

Delivery was fast.I have 2 of them for my Sundown setup.They look and perform great.

Very Heavy and expensive customer service is basically non existant

Overpriced and fails just after warranty.
