WHAT A BEAST!

Nothing beats XS Power. I have the D5100 under the hood with big 3 done and two D680's in the back. My speakers go harder than ever and I get almost no headlight dim.

Happy to see Sonic Electronix carrying XS Power!

Excellent starting battery for import vehicles.

Great Performance

First off, the product claims to be D-51R is size.. Its very close, but is larger and will require some modification to the battery mount on your vehicle (if using stock battery location). These guys do make a billet mount, of which I am looking to acquire.

I would definitely recommend one of these batteries (D5100R) if you are looking to improve starting, increase gas mileage (noticed a 10-15 miles per tank increase). The other advantage of this is the quicker starting and more power to the starter motor. I will also add it woke up my audio equipment (Cleaner/Crisper highs, not to mention the tighter/harder hitting bass)

A must have if you want an all around better battery over Stock! This is far superior to Optima's Yellow Top (D51R)

Would buy again.

No problems with the XS Power batteries. Stays charged and works fine.

Great Battery

I replaced my starting battery with this one, noticed an improvement in sound from highs and sub right away.

Best Battery I Have Ever Owned

This battery is by far the best battery i have owned. i can run my stereo with the car off with no problem. I also don't have any lights dimming when the bass hits, and my throttle response is so much better.

Great battery

I bought this battery for my 98 honda civic and it fit perfectly in the factory battery spot, I also ordered battery terminals and had to adjust the hood because the battery sat a little higher than the factory battery did. If you buy this battery make sure you get the battery posts as well if you need them because it only comes with 2 bolts, so if you want more power for your car audio and you own an import and don't want to run wire for a second battery then I recommend this item.
