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.

XS Power offers a handy vehicle guide on their website. Simply enter the year, make, and model, and you'll instantly receive a list of batteries that should fit your vehicle. And they'll recommend installation accessories to help make things more convenient. Or just give us a call and talk to one of our experts.

Note: XP Series batteries do not have reinforced casings and are not recommended for daily under-the-hood applications.

Important Note: It is very important to properly charge an Absorbent Glass Mat (AGM) battery before using. Improper charging can permanently damage the battery (including but not limited to swelling), and will void the warranty. These chargers (sold separately) have a microprocessor that monitors the charging process to avoid overcharging, and are recommended for this battery.

More details on the XS Power XP750

Product Research

Features

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.

Charging the Battery: It is very important to properly charge an Absorbent Glass Mat (AGM) battery before using. Improper charging will permanently damage the battery (swelling, etc.), and will void the warranty. XS Power offers two 12-volt High Frequency IntelliChargers designed for charging AGM Batteries: the 8-amp HF1208 and the 15-amp HF1215 (both sold separately). The chargers have a microprocessor that monitors the charging process to avoid overcharging, and are strongly recommended for this battery.

Note: If the battery is damaged (swollen, etc.) due to improper charging, or from not using an intelligent charger, Crutchfield will not accept a return on this item.

Specifications: The XP750 has the following specifications:

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

A
Greetings Braulio. Thank you for your question. The XS Power XP750 secondary battery is rated for up to 1500 watt systems. Unfortunately, for your type of set up, you may need a full size secondary battery.

Q
Can I ground this battery to the same spot that my amps are grounded?
andrew  Aug 22, 2022
1 answer
A
This additional battery may be ground to the chassis of the vehicle in the same way as the amplifiers. We have a kit available that includes this battery as well as the additional wiring and fuse holders for installation. Here's a link to that kit: www.crutchfield.com/p_122XP750CK/item.html

Q
Can this battery be installed on it's side?
andrew  Aug 22, 2022
1 answer
A
These batteries can be installed on it's side, Andrew. The gospel from XS is that as long as you do not exceed 90 degrees in whichever orientation (mounting the battery upside down) you are good to go! This battery's compact size lets you get creative with your installation. 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. This particular battery even comes with an optional matched aluminum bracket in the link below for a super slick install! https://www.crutchfield.com/p_122511/XS-Power-Side-mount-Box.html

Q
How many farids is it?
john  Jun 13, 2021
1 answer
A
This is a battery not a capacitor, so it's not measured in farads. It is rates for 750 amps max output at 22 amp hours. It will perform better than a capacitor. This one is good for a system under 1000 watts. If you are over that go to the next size up battery.
john  Jun 13, 2021
Q
I have a 2000 rms watt rockville db16 powering 2 audiopipe bdc4 2 ohm 12s. The rms of the speakers is 1100 each. I have a cap, but lights still dim with gains less than half way up, volume at approximately 55%. Will this help? If not, I am open to best suggestions.

Q
If i purchased said battery, could i run it back to my oem battery then to my big 3 to continuously charge said battery?
chevy7@  Oct 26, 2020
1 answer
A
In a manner of speaking yes, this battery will "charge" the OEM location battery, but only insofar as its voltage remains higher than the OEM. Once the internal voltage equalizes between the two, charging stops. A few unsolicited bits of advice without knowing your objectives: if you have a long run it's a good idea to place fuses close to both batteries, a single fuse will protect electrical equipment, but leave 15ft of copper wire welding itself to your car. A positive terminal quick disconnect switch can make life easy when you need to disconnect battery. After Big3, if the alternator remains insufficient to fully charge OEM battery, in all likelihood the XS will not fully charge either, so you consider a trickle charger. It's a hassle to plug your car in like a hybrid, but hopefully the charger will bring both to maximum charge while it's sitting.

Yessir will absolutely help keep your electrical at a better voltage when the amp really draws more current
johnny  Jan 31, 2018
Q
Do you wire this in line from factory battery to the amp? Can i use my regular trickle battery charger to charge this, or can i install the battery and let the alternator of the car charge the battery

I wired mine in line on my fourwheeler for a extra battery but im sure you can do the same
james  Dec 20, 2017
A
Wire it in parallel (like a cap) using the amps power wire and ground at same spot as amp. (If you use a battery isolator you can separate the batteries when key is off but is not needed nor is any method preferable. As far as charging , you alternator will charge it as long as the amps power wire is hooked to main starting battery. Be sure to install fusing on both sides of the "charge wire" to protect the car. The amps power wire will effectively be called a "charge wire" now for the aux XS power battery. The XS power battery rests at a voltage approximately 1v higher than a lead acid battery. Also keep in mind an AGM type battery can not be "float charged". Most typical "trickle chargers" raise the voltage to 16v to desulfuate the cells on a lead acid type battery by heating it up internally. So the use of an AGM charger will be needed if you have no way of telling what type you have. As long as the charge cycle never exceeds 14.4v than a lead acid charger can work as well. Andrew

I would charge it completely before installing follow the directions you will have better results

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

Don't remember the battery was horrible and I returned it to Crutchfields

I use a charger with an AGM setting and I trickle charge it.
