Incredible delivery!! NO BETTER......

Quality price I love xs power d3400r great I will buy again

Excellent battery best battery I ever owned Five Star

Battery seems to work great cant wait to see how it does at the track

Best battery to buy!!!

So far very good. Seem way better that warehouse store batteries. Did add a 350amp alternator. My stereo system sounds better also .

Fast shipping

I love this battery. I highly recommend it. Its worth it.

Arrived a day early and is very heavy! Been in about a week now and i must say it is very impressive. Im still on stock alternator and wires and using cca and this guy will not drop below 13.4 unlike the Walmart ever start platinum which was dropping down to 12.5 at the same volume level. Very impressive!!!

A amazing product really pleased with and company

Came in good time and it works great only thing I didn't like bout it was when I opened the box it had a lil moisture on the top post but it works amazing

Had it for over a week now and it appears to be working great! I have a 3500 watt rms subwoofer, and this battery is paired with my Duralast Platinum AGM and my 320 amp alternator. My headlights don’t dim at all when the bass hits.

Very satisfied, fast shipping and packing was great no issues at all. Will definitely do buisiness again.

Fits like a glove
You need to have more options for battery boxes

XS is always great. My last D3400 lasted a little over 7 years. I wouldn't even think of replacing it with anything else.

Xs power batteries are the best

Heay but overall better quality than yellow top. Will definitely see a difference when peak voltage is required

Great product I love it

This battery has served my well, does a great job and is an excellent starter battery/smaller car audio build battery!

Love it

So far so good.

Good products, and that's all I run in my vehicles!

Best batteries on the market. My first one lasted 10 years before cranking started to slow down. Just ordered a replacement yesterday and it arrived today.

Phenomenal. Huge upgrade on the standard battery I was using before. And Customer Service was great to work with.

Battery is great but packaging is terrible. Definitely got beat up in shipping. Handle was broken and small hardware scattered throughout the box. No shipping foam material just a battery in a cardboard box. But still delivered powerful xs power!

good stufff

Very happy with the New Battery!! I know it was pricey, but will worth it!!!!

Does what it says. Arrived on time and a big notable difference in more power. Get you one!

Great power upgrade

Works great perfect fit in 2000 jeep cherokee 4.0

This battery accompanied by the 500 xs capacitor does both long term amp hour supply and instant cranking support. Keeps our drift car going and fans and water pumps running even with engine off.

My first XS Power Battery.. so far so good

Love it ! Exactly what i wanted/ needed ! Excellent power... price was fair too !!!
