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

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.

Real good battery never fails

Top quality design, and #1 battery! Night and day difference! My Taramp 5k smart amp wasn’t getting the power with those auto parts store AGM’s, so after reading all the positive reviews I went ahead and bought this battery. Let me tell you, I notice the difference immediately more powerful sound and more volume without the amp going into protective mode. Sub was hitting the lows 28hz and bass meter reading 2,[email protected] 13.7v 141db. Volume couldn’t go pass 22 without clipping, now it goes 28 and with more fine tuning it will be a beast. Oh, sub is wired to 0.8ohms and running only on a 150a alternator.

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.

Put it in a 2000 jeep cherokee with a fairly powerful system. It keeps the voltage up so the lights basically never dim. Voltage used to hit 12.0 now it rarely drops below 13

Terrible Battery! I bought two xs3400 batteries for my stock F250. I have only factory equipment and thought these batteries would be an upgrade from my Optima batteries I had previously. They failed at 16 months and the Company will not replace or credit me. The Optima battery lasted 6 years. Do not purchase these batteries. I have spoken with a mechanic who said he’s seen problems with this brand. Beware

Love these battery's good power. This is my sec9nd one and haven't had any issues

working phenomenally solved headlight, dimming issues and voltage drop reduced ,delivered at 12.7 V charged overnight and i love it. It’s bigger than I thought it was even though I measured, but it fits will update if it blows up and give it the five stars it deserves

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.
