Awesome battery here. A little on the expensive side but worth every penny. Ive had mine for about 6 months as my starting battery and ive had no problems what so ever. Still holds charge like brand new

I purchased this battery for my 1999 Ford F150 to replace the under the hood battery and I gotta say, it is a great battery. Very worth the price and definitely an upgrade. It starts up faster than ever before and has more than enough power.

I have a 99 Dodge Caravan, I'm running 4 12's (Hifonic Brutus), 1606 Brutus amp, 800 PowerBass amp [highs]. This batter is the only one in the vehicle and the head ligths barely barely deem. This is a good a**battery

As well customer support from XS is on point. I already recommend XS to any of my friends or strangers who are in the market for an electrical upgrade. Will be purchasing from SE more XS batteries in the near future.

I'm always running my stereo with the truck off for hours and this battery hasn't let me down yet

Very pleased and if you wanted the reserved power you need this battery stacks up with what you need I plan on buying more for my build!

I Bought this battery back in feburary and i havent had any problems out of it! it use to read 12.8-12.9 volts now it only read 12.5 all the time! but besides that i love it

I didn't think that a battery would make such a difference in how powerful my system sounds. I have an RE XXX d2 15'' on a 3000.1 amp. my regular acid battery went to junk within the first two weeks of my new sub. Now with this new battery, I also have a small xs battery to help the juice it takes to move the power hungry sub. My voltage is around 15V with the two batteries and drops around to 14 when im around full tilt. Barely dims lights and I am very happy. My roof in my s-10 extended cab flexes on quarter volume, before it needed to be around 70% to start flexing and rattling. I can tell i've got an extra 5 db atlesast just from a battery swap!! It is bigger than a standard battery so be prepared to do some body work. I got lucky and it fit snug. Now i need a high performance alt to take it to the next level for next summer!! XS for life!!

This battery gave me the juice my amp needs! My amp puts out a little more than 1800 watts rms at 2 ohm.. Before I bought my D3400, my voltage would drop down to the low 12's, but since then it doesn't drop lower then 13.4 on a full charge. If you don't want your pretty new amp you just bought to burn up like a firework then you need this battery. I only gave it a 4 star on "ease of use" because the new battery post's were on the opposite side than my old battery so I have to move around my big three wires.

I've had several POS batteries before, and to be honest the price of the D3400 was the selling point. I was prepared for the worst.

THAT was six months ago, and I have been using it daily for lighting in our camper. I have YET to charge it. WHAT A BATTERY!!!!! looking forward to many more trouble free months.

I'd recommend this battery to anyone.
Holds voltage like no other. Have not had to charge it yet (after 1 year of everyday pounding on a stock alt). It holds 12.6 after days of sitting, and I don't let the alt charge it before i park for more than 1 min and I only do that because i don't want to attract attention in my hood, not because the battery needs it!

Do some research on XS power if you still have any doubts and you'll see they have become the #1 choice among car audio fanatics.

Plan to buy another XSbattery or two for my next build!

The Xs D3400 is by far the best underhood starting battery in its class (group 34) i ran 1500 rms on just this single battery with close to 0 voltage drop XS is FTW.

SonicElectronix knows quality....Enough said. I ordered the battery for my S-10 as an extra battery for my system. They were the cheapest in product and shipping. The quality of products from Sonic varies. They taylor from beginner to pro, rich to poor and in between. At great prices
I have been a returning customer due to the fact that they always take care of me the customer and to me that matters more than the product I am buying. As far as the battery goes its awesome and has been keeping my amps happy and electrical system steady. I only regret not buying 4 of these instead of one.

This battery went right into my factory location and bolted right in. Performs great. I drive a Saturn LS1.

I purcjased this battery through a different dealer earlier this summer, and i will tell you right now that this battery is AMAZING! Nothing wrong with it at all.... except I'd recommend not swapping batteries at 3AM. :P

I love my XS batteries. Im currently running two of these 3400's in my truck. My sub amp is ran low at .5ohm, so proper electrical is good. Total RMS is around 4200 and voltage is always good. Would definatly recomend this and will continue to run XSpower for a long time.

I Installed this for a soundstream Rubicon 2500.1 and it gave it all the power it needed! I would def suggest it to anyone with a 2000-3000 rms system.
XS Power Forever
