HC2400

Works as advertised. Bass stays strong with no light dim .

D4S jp23 on 2 hertz ss 15's + hertz ml power 4

the battery showed up almost fully charge (13.6v) and has my system slamming, my front battery is almost dead so I just ordered a second one, the voltage stays above 14 when I charge the front battery and drops to 13v when the bass hits and my front battery loses charge. I suspect my battery was on it's way out for awhile before I began installing my system but my entire car runs better now, not just the sound system!

Buy it

This is a very underrated battery. Why more people aren't running this group 31 over other brands is beyond me. The price and performance literally can't be beat.

I own two, with an agm group 34 as my starter and it holds my 4k amp at over 13 volts during full tilt. Thats on a stock alt.

Shipped very well, three box shipping with peanuts
Dimensions were exact
Battery came resting @ 12.9v
Highly recommended

Great and powerful

This battery is everything I expected plus some. Works great for my Skar 3500 amp and Skar 4 channel. Maintains voltage. Comes with everything you’ll need.

Works great

I've bad this installed for a month and works great. Will be getting another when I get another amp

Heavy SOB

Received exactly what I expected. Good packaging, but I've yet to install so performance is TBD.
