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

I originally ordered my D3400 from Crutchfield. Installed it as a main battery and it performs brilliantly. Engine starts no problem, and it was powering a Crescendo 2K, and MB Quart Onx4.125 amp with no dimming on a stock alt. I eventually decided to go bigger with my install and called on Amazon for the order, since they offer very fast shipping. Installed 2 more D3400s in the rear, and they power 5K of amps just fine. Upgraded the alt to 250a, because I needed the power but these batteries are very good. The only thing is they are very heavy, but that's to be expected from a larger battery. Compare it to the Yellow Top Optimas and I would say the XS Power is a much better performer. Resting voltage is around 12.8 with mine so they hold a really good charge. Definitely buy these if you are planning a stereo and can fit it. I would install one as a starter battery, and the D3100 in the rear if you are installing a high demanding stereo set up.

Best Battery Ever this is the 4th one of these batteries 2 in my Tahoe, 1 in Mitsubishi Eclipse and 1 in my 73 Camaro Muscle car with a big block! has no prblem running 2400W RMS stereo full out! you need this for car stereo beef ups

Installed this to replace my optima yellow top and this makes the optima battery look like a Duracell battery. I also ordered the side mounts, which were easy to install. This has more juice than you will ever need and i highly recommend this to anyone who has a serious system or getting started on one. This Is A GO!!
