I needed a better battery, this should do the trick.
Daniel S on Jun 5, 2015
Hi I'm running a 1100 watt rms system... I'm experiencing headlight dimming and was wondering would this battery do the trick??1 Some people say change my starting battery, some say add a secondary battery... any suggestions would be helpful... thanks
Durrell P on Oct 3, 2016
Best Answer: I'm sure the specialist from sonic well tell you the same. Check your electical system first. Your alternator and ground. Upgrade those first. I bought mechman alternator and xspower grounding kit. Those helped alone with the dimming. The extra battery was the icing on the cake.

What's the best way to charge this battery?
Harry D. Staff on Oct 13, 2014
Best Answer: With a battery charger capable of charging AGM batteries, do not use a battery charger if it does not indicate it will charge AGM batteries.

At 300 constant watts how long will this battery last?
A shopper on Nov 21, 2014

Unfortunately, your inquiry is fairly vague, generally speaking. However, it may be an inquiry better suited to be answered by an XS POWER technician.

will this battery work in an 2004 Silverado 1500 extended cab?
Reuben L on Sep 10, 2014
Best Answer: Hello Reuben,

Like our awesome customer Marcel suggested; XP Series ARE NOT TO BE USED UNDER THE HOOD!! XP series a PACKED to the brim with lead. This makes them unmatched in the market. However, the XP series are designed with thinner walls - hence the price - and WILL NOT withstand the head of an engine.
Your 2004 Chevrolet Silverado 1500L Requires BCI Group # 78 , which means you can fit Up To the XS Power D3400; the equivalent of the XP950 is the XS Power D975.

Will this battery charge with solar?
v R on Feb 2, 2016
Best Answer: Hello,

We suggest contacting XS Power Tech Support AND the company behind your Solar Charging system. Unfortunately, in our market that isn't a widely used setup, and we don't have the available answers to provide.

Best Answer: Hello,

XP series batteries are NOT intended to go under the hood, next to an engine within a vehicle - this is what the D series is for. Furthermore, whether the batter can "replace" your existing battery must be determined by you, simply by measuring your current battery. Lastly, two XP950 , in the right situation, would be a great addition for an extensive audio build.
