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 reliably. 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.

Compact size, leak-proof design

Their compact size lets you get creative with your installation. 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.

Don't let the small size fool you — the cranking power of an XS Power battery can be two to three times the power of a flooded battery of equal size.

XS Power D680

XS Power's compact D680 deep cycle 12-volt battery provides up to 1,000 maximum amps and has a capacity of 20 amp-hours. You'll need a protective case if you're installing this battery in your engine compartment. Check "Accessories" for other items that'll help you install and secure your new battery.

XS D680 is AWESOME!!!

Written by: Adub from Texas on December 13, 2015

Crutchfield Customer Review (What's this?)

For such a small size it packs a punch. Cranks over my highly modified 93 cobra instantly vs the odyssey PC680 battery it replaced. Can't fit a full size battery due to a massive supercharger so this fits perfect and still has the power to start the car.

Pros: compact size and powerful

Cons: have to adjust or get new post terminals for the vehicles wires as even the largest accessory post might not mate up securely.

Product Research


Overview: The XS Power D680 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.

Terminals Needed: This D-series battery does not come with battery terminals, so you will need to purchase the proper terminal adapters to fit the inner diameter of your power ring terminals before installing. 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). You could also choose the Short Brass Post Adapters (#580) or the Long Brass Post Adapters (#586).

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, D-series batteries are installed in the trunk or hatch of the vehicle, close to the amplifier. The Stamped Aluminum Side Mount box (#511 or #512) will allow you to mount the battery cleanly to a side wall. A second battery install kit, such as the XS Power AK1000, can be used to connect the D680. It should be wired in parallel (+ to + and - to -) with your vehicle's battery. Should you decide to mount the battery under the hood, you will need the MC-D680 Protective Metal Case to reinforce and protect the battery case. The 680 Billet Aluminum Hold Down (#515) can also be helpful in mounting the battery under the hood.

Specifications: The D680 has the following specifications:

  • MAX Amps: 1000 amps
  • Cranking Amps (at 32°F): 320 amps
  • Reserve Capacity: 28 minutes
  • Discharge Capacity: 20 Ah (amp hours)
  • Dimensions: Length=7.13", Height=6.57", Width=3.03"
  • Weight: 15.42 pounds
