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

Works well so far; this high-quality AGM battery effectively powers my stereo system and provides reliable starting performance. The vehicle requires significantly more cranking amps than what I need for daily use, and the battery handles this with ease, maintaining excellent condition and durability.

Very good... perfect size and a lot of power.

I've got this powering my X15v3 on a Taramps MD3000.1 and I've had no issues thus far. When I purchased it though, I wish I'd have realized that it didn't come with battery terminals lol Had to wait another day or 2 for those to come but otherwise, this thing has done exactly what I've wanted it to and had no issues. Would absolutely recommend and when I inevitably upgrade my stereo again I will be buying a few more XSPower 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.

This battery batteries so damn hard. Don't forget your accessory kits though, posts and side terminals are not included. Worth the cost!

I mean its a good battery.. at first i was not sure but i guess its normal for a battery to sit at 12.8. I was hoping for it to be nearly 13 volt at full charge since its a AGM Xs power, and i also seen other reviews people saying it sits around 12.9 / 13.0. Mines just sits at 12.7 / 12.8. I do know a normal lead acid battery 12.8 is a good sitting voltage also full charge voltage. Ill see how this battery does a few months from now. Update- i had a feeling this battery sucks! They are a hit or miss. After 4 months battery looses charge. It sits at 12.7. Turn the ignition on and rapidly voltage drops to 12.2 / 12.1volts. No good! Never again will i spend a dime on this brand. Ill stick to Everstart. Cheap but those battery will last 4 to 6 years faithfully

Battery holds up nice to my 400a mechman alternator in my 2012 Tahoe thinking about getting another

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.
