Give your vehicle the necessary juice to perform at its best. XS Power deep cycle batteries can act as replacements for your car's standard battery, or you can use them as auxiliaries to power your high-performance sound system and hydraulics reliably. If you've got a boat or an RV, XS Power's got a solution for your electric needs, too.

If you've got a boat or an RV, XS Power's got a solution for your electric needs, too.

AGM technology

XS Power deep cycle 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. This leak-proof, non-hazardous configuration typically lasts longer than normal replacement batteries if properly charged. 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.

Leak-proof design

Since there are no external vents on an XS Power battery, you can mount it in a passenger compartment, below a seat, or inside a glove box without fear of leaks that cause 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 D3100

The XS Power D3100 deep cycle 12-volt battery provides up to 5,000 maximum amps and has a capacity of 110 amp-hours. A reinforced plastic case protects it in your vehicle. Check "Accessories" for items that'll help you install and secure your new battery.

Great Product, seems to do what it is designed for.



not so great

raymanrox from raleigh on 8/4/2014

Crutchfield Customer Review (What's this?)

I got one of these for my Nautique. I had just finished installing a Wetsounds system and wanted the best power source available. When I installed the battery it worked fine, but was no better than the Interstate std marine battery I already had! After using for a little more than a year, the battery stopped holding a charge. I had it tested twice, bad battery! Had to ship it off to XS, cost almost $60!!! I will post again with the outcome of the warranty return. For now, I am not happy!

Pros: Great service from Crutchfield

Cons: expensive return, product not satisfactory

Awesome Battery

DJ from Michigan on 4/9/2014

Crutchfield Customer Review (What's this?)

Awesome battery and it delivers every time I need it. Are there better Group 31 Batteries out there? Now that would be a challenging question because this battery seems to be at the top of the Group 31 chain. Crutchfield was great with delivery and prompt shipment information.

Pros: Power, Sturdy, Durable

Cons: PRICE. Guess you have to pay to play but lowering it by $40- $50 would be nice. Not Crutchfield's fault.


OHP387/ShelRob from TULSA, OKLAHOMA on 2/17/2014

Crutchfield Customer Review (What's this?)

Great battery works awesome and looks good too in my custom install with the chrome battery holder. I never worry about listening to my music at the lake/park with this battery.

Pros: Great company both Crutchfield and XS POWER and both stand behind the product. Prior to purchasing I could not find one person or bad review on the web about XS POWER so I knew it was a good investment that was needed for my 6000 watts in my HUMMER H2.

Cons: Do not have any cons. I research everything prior to purchasing so I know what I am getting prior to arrival. I knew I was getting a top of the line quality product!

Pros: Battery life

Cons: weight

The best battery out there

Pros: Handles a lot of power

Cons: Heavy

Good but not the best.

Richv72 from bay area on 7/5/2012

This is a really good battery, but its not the best of the best that xs power makes, the xs power d2250 is larger and more powerful and unfortunately no one sells them. If I can get my hands on 2 xs power 2250 I will run all xs power, if not I will run 2 stinger sp2250 which is larger and more powerful than the xs power d3100. I think xs power has cornered the market because they have invested money in car audio forums and are partners, so basically whatever they say is law and cannot be disputed on the forums. So if everyone is saying the 3100 is the best on forums, without anyone being allowed to challenge this notion, it becomes fact. I will say this though you can't go wrong buying an xs power battery, they are great batteries and definitely deserve respect. But the d3100 being touted as the most powerful battery? definity not.

Pros: Great battery

Cons: Over hyped, not as good as xs power d2250 or stinger sp2250

most awsome batterys

basshead813 from mobile,al on 7/27/2011

XS Power D3100

Arthurk from Indianapolis on 2/27/2011

These batteries are simply the best money can buy. Makes a huge difference for a big system.



Can't be beat

Db from Orlando, Fl on 2/16/2011

The XS Power D3100 is by far the best and most powerful battery you can purchase. I have a couple Incriminator Audio 20.1 amps (clamped at just over 200amps each) in my system with 250amp alt. I have tried the stinger, kinetic, and batcap batteries even the batteries larger than the D3100 and they can not compare. I saw a huge voltage drop with the larger kinetic 3800 batteries. Changed nothing in the system except for the batteries (2 D3100 for 3 hc3800) and the D3100 stopped my voltage drop. I had the stinger and batcap batteries before the kinetics. I wasted a lot of money on batteries until I finally bought the XS Power D3100. Wish I would have just went ahead and got the D3100 first. Would have saved a lot of money if I would have found the D3100 first.




Hands-on research

Product Research


Overview: The XS Power D3100 is a 12-volt battery that is designed to be used as a supplemental power source in your vehicle, or it can replace your vehicle's OEM battery. It can supply the power needed to run your high-powered audio system, better than a standard battery.

Terminals Needed: This D-series battery does not come with battery terminals, so you will need to purchase the proper terminal adapters for your application before installation can take place:

  • Car Stereo Installation: You will need terminal adapters that fit the inner diameter of your power ring terminals. Recommended terminal adapters include: Two 5/16" brass stud adapters (#589), Two 3/8" brass stud adapters (#590), Two 5/16" + Two 3/8" brass stud adapters (#588), or Two 3/8" zinc-plated steel stud adapters (#587). For dual-battery installations, a second battery install kit, such as the XS Power AK3500, can be used to connect the D3100 in parallel (+ to + and - to -) with the main battery.
  • OEM Battery Replacement: The D3100 fits the BCI Group 31 vehicle applications and will fit many large truck, bus, and motor coach applications. If you are installing the battery under the hood or replacing your vehicle's OEM battery, you will need either the Short Brass Post Adapters (#580) or the Long Brass Post Adapters (#586) to connect your battery cables. The 3100 Billet Aluminum Hold Down (#598) can also be used to install the battery under the hood.

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.

Charging the Battery: It is very important to properly charge an Absorbent Glass Mat (AGM) battery before using. Improper charging can permanently damage the battery, and will void the warranty. The XS Power HF IntelliCharger for AGM Batteries (sold separately) has a microprocessor that monitors the charging process to avoid overcharging, and is recommended for this battery.

Specifications: The D3100 has the following specifications:

  • MAX Amps: 5000 amps
  • Cranking Amps (at 32°F): 1360 amps
  • Reserve Capacity: 237 minutes
  • Discharge Capacity: 110 Ah (amp hours)
  • Dimensions: Length=12.99", Height=8.43", Width=6.81"
  • Weight: 75.4 pounds

Q & A

I will assume you have already gone 1/0 gauge from your battery to the amps. If the lights are dimming when you are in motion then mark my words: Buy a more powerful alternator FIRST. It was a good decision to take care of the Big 3 first, but if your lights dim then there's simply not enough horse power coming from your alternator. Shop for an upgrade and buy the most powerful (but compatible) alternator you can afford. Also, remember that it's primarily sub amps that such your power. If you're going for SPL (outrageous loudness on the low end side) then you may need to shop for a more efficient amp(s). I'm an SQ guy running about 3000 watts of JL HD amps. I can't recall dimming once. [ MARQUES  Apr 23, 2014 ]
If you are running anything under 3k this battery alone will almost completely solve your problem. If you are running alot of power i would look into an upgraded alt at some point down the road. [ BRICE  Apr 16, 2014 ]
absolutely best battery ever hands down want to buy another one but don't have the money their batteries are expensive but well worth the money [ LLOYD  Apr 16, 2014 ]
