Power for mobile or marine applications

Looking to give your vehicle a little extra "oomph," power-wise? XS Power's XP Series batteries deliver reliable supplemental energy for your high-performance car audio system and hydraulics. They also make a great solution for your boat or RV's auxiliary electric needs, or for just about any application outside the engine compartment.

Advanced AGM technology

XP Series batteries feature a sealed absorbed glass mat (AGM) design that incorporates special glass fiber mats that contain the acid electrolyte between the lead plates, rather than a standard flooded (liquid) design. These batteries actually store energy, so you don't have to add a capacitor to your system to get a quick burst when you need it.

Designed to fit nearly anywhere without leaking

The compact XS Power XP750 12-volt battery provides up to 750 maximum amps and has a capacity of 22 amp-hours. It'll provide a big boost to your car audio system, and it offers ready reserve power for your boat or UTV. You can even use it for non-vehicle applications, such as emergency lighting, alarms, and more.

This battery's compact size lets you get creative with your installation. Since there are no external vents on an XP Series battery, you can mount it in a passenger compartment, below a seat, or inside a glove box without fear of leaks — no more worries about corrosion or damage to chrome or paint. XS Power guarantees their batteries will not leak, even if damaged. These batteries also resist extreme vibrations so they'll perform in the trunk or hatch area without skipping a beat.

Product Research


Overview: The XS Power XP750 is a 12-volt battery that is designed to be used as a supplemental power source in your vehicle. It can be used to provide additional power for your car audio system, or can be used in marine applications. It is not designed to be installed under the hood or replace the OEM battery in your vehicle.

Terminals: The XP750 battery has a terminal insert with an M5 thread. It comes with socket cap head bolts that allow you to fasten the ring terminal to the battery, so no additional hardware is necessary. The XP750 is not compatible with other terminal adapters offered by XS Power.

Absorbent Glass Mat (AGM): XS Power's AGM (Absorbent Glass Mat) batteries use a fibrous material to suspend the liquid electrolyte against the lead plates. Because the electrolyte is absorbed in the material, there is little chance of an acid leak, even in the event the case is ruptured. AGM batteries contain more lead compared to traditional "flooded" batteries, thus producing more power.

Installation: In typical car stereo applications, XP-series batteries are installed in the trunk or hatch of the vehicle, close to the amplifier. It should be wired in parallel (+ to + and - to -) with your vehicle's battery. A second battery install kit, such as the XS Power AK1000, can be used to connect the XP750.

Specifications: The XP750 has the following specifications:

  • Maximum Output: 750 watts
  • Reserve Capacity: 28 minutes
  • Discharge Capacity: 22 Ah (amp hours)
  • Dimensions: Length=7.13", Height=6.57", Width=3.03"
  • Weight: 14.5 pounds

I use a trickle charger, works just fine. Any type of 12v charger will work [ Josh  Feb 17, 2015 ]
I use a 2amp trickle charger by battery tender and it works well to maintain and charger [ MAURICE  Feb 16, 2015 ]
James, I bought this battery to convert my cooler into a music playing device. I bought a small trickle charger that had secure lead connections (i.e. bolt on) and just plug it into the wall in my garage. The trickle charger had a 2-prong plug in-between the charger and the leads that you can easily disconnect from the charger while leaving the leads bolted onto the battery; I just drilled a whole in the side of the cooler to accommodate for that. For the past 6 months, it has worked well - usually holds about a 10 hour charge depending on how loud the music it. [ ANDREW  Feb 16, 2015 ]
I just use a trickle charger (battery maintainer) that I bought at a local retailer to maintain a full charge. [ jack  Feb 16, 2015 ]
