XS Power D1600 AGM Battery

XS Power D1600 Group 34 16V AGM Car Audio Battery

For builders who run a 16-volt electrical system and refuse to settle for anything less than maximum cranking force, the XS Power D1600 16V AGM battery in Group 34 delivers outstanding power density in a manageable package. The elevated voltage platform works in concert with a compatible high-output alternator to feed even the most demanding multi-amplifier setups without dipping into voltage sag territory.

The D1600 is a proven platform among SPL battery competitors who need a dependable, high-CCA unit that can keep up with repeated hard hits. Its sealed AGM construction eliminates the risk of acid spillage in a tucked or angled install, and the robust internal plate design handles the aggressive charge cycles that come with pairing it alongside a high-output alternator in a real-world competition rig.

We offer free shipping in the United States. Orders ship in approximately 3-5 business days, sometimes sooner. Many alternators are shipped the same day. Alternators that require a custom bracket can take 5-8 business days. If for some reason parts are on back order, we will notify you, but this is not common. If order is placed after 12pm EST, shipping timeframes begin the next day.

REQUIRED Installation Steps:

(Wear eye protection, remove jewelry/loose items, and allow car to fully cool before starting installation)

Batteries must be fully charged before installation.
Make sure vehicle is off and engine is cool.
Disconnect the negative cable from the battery/batteries.
Disconnect all other wiring from the alternator.
Remove the belt (note the belt routing before removing).
Remove the bracket bolts and original alternator.
Mount the new alternator. Typically the original bolts will be used.
The belt must be replaced with a .5 to 1-inch shorter belt when installing a high output alternator, unless otherwise specified.
Install the new belt. Make sure the routing is correct and the belt is aligned with all pulley grooves.

Connections Of Frame/Body: Clean all metal surface of any paint or rust with a wire brush or die grinder. Use a conductive corrosion inhibitor available at any electrical parts supply store.

Grounding (Uni-body frame warning): Many newer vehicles have “uni-body” or sheet metal frame structures with no traditional “full frame”. Because of seams and adhesive attached body components, additional steps may be required for proper chassis grounding. Choose the location on the sub-frame with the thickest metal possible. If there is lower than spec charging voltage at the battery, move ground connections or add additional ground cables to different frame components.

*** WARNING *** Keep all electrical wiring at least 12” away from heat sources to avoid fire of the cable jacket!

There are THREE Regulator styles. Read each to determine which one your alternator has and read its the included notes:

Factory Plug: The factory harness can be plugged into the new regulator. Be sure factory plug is clear of all debris and fully snapped into place in regulator.
Turn On Single Wire Alternators: Follow this step ONLY if we shipped a pigtail plug with your alternator. Connect the excite wire (L) to a 7v to 15v ignition power source and connect the sense wire (S) directly to positive post on alternator. See picture of the Pigtail Plug below. PIGTAIL PLUG:

1987-1990 Jeep Comanche 4.0L High Output Alternator

Self Excite Alternators: Self-exciting or better known as “one wire” alternators will have NO plug on the alternator, and the OEM alternator harness plug will be left disconnected. This type of alternator requires only the positive and negative battery cables to be connected to the alternator to function. These alternators are internally regulated and will turn themselves on and off with engines rotation and regulate their own charging voltage. (This may cause battery light to come on).

Gauges

It is highly recommended you add a dash mounted volt gauge.

Connect the battery ground and confirm all other electrical connections are complete.
Confirm the belt path is correct and clear of obstacles.
Before starting the vehicle confirm that the battery is charged, as starting the vehicle with a discharged battery can damage the alternator.
Use a battery charger to charge the battery first if voltage is inadequate.

Ground Path Resistance Test

If resistance is greater than 0.1V confirm the following:

Confirm that all paint, anodizing, or rust is removed, and the connections are to bare metal.
Make certain all terminals are tight to the wire.
Make certain the ground wire is of proper size.

Charge Path Resistance Test

If resistance is greater than 0.1V confirm the following:

Make sure alternator charge post nut is tight.
Make sure charge wire is proper size.

Frequently Asked Questions

We offer free shipping in the United States. Orders ship in approximately 3-5 business days, sometimes sooner. Many alternators are shipped the same day. Alternators that require a custom bracket can take 5-8 business days. If for some reason parts are on back order, we will notify you, but this is not common. If order is placed after 12pm EST, shipping timeframes begin the next day.

We offer lifetime warranty on alternator labor and a one year warranty on parts. All orders are heavily wrapped for shipping with several layers of big bubble wrap and two layers of boxes along with a Fragile sticker on the box. If you have to ship your alternator back, please be sure you wrap it the same way to prevent further damage. See more details on our warranty page.

Each of our high output alternators come with smaller overdrive pulley. This pulley is made to increase low RPM charging for maximum output. It is custom for the diameter of the overdrive to be less than your factor pulley, depending on the kind of vehicle you own. For this reason, unless otherwise specified, you will need at least a 1/2 inch shorter belt. You can purchase this from any auto parts store. In using the belt and the pulley system, ensure that each part of the pulley system is free of oil or grease, this will help its efficiency.

It is important to make sure that the small regulator plug that is located on the back of the alternator is well plugged in for the correct functionality. Do not forget to plug it in completely, try not to jam the plugs in backwards, and avoid pinching it in order not to create a short. For more information on regulators and wiring see installation instructions.

Our high output alternators come with an overdrive pulley. The pulley is designed to improve low RPM charging so that it yields maximally. Do not change this overdrive pulley out with a larger diameter pulley. When alternator pulley diameter is increased, the output amperage decreases. Changing the pulley will void all warranties

As promised to all our customers, our products are fully tested ensuring their outstanding performance before shipping. In our experience through the years, it is in many cases not the alternator itself. You must ensure you consider a few possible concerns in your troubleshooting – please read the instruction manual thoroughly.

The reason could be one of two things: Either the plug is wired incorrectly or the computer is sensing the higher voltage and causing the battery light to come on even though the alternator is charging properly. Please refer to the instruction manual tab on the website for specific instructions that will help you with wiring. For some older vehicles, the factory style regulator is not available with the hairpin style alternator. This is why your high output alternator will come already “upgraded” with the 15 volt regulator. It will have an oval plug which requires splicing into the factory plug. This is a simple ,fast step and these instructions are detailed for you in the instruction manual.

We currently offer a curated lineup of powder-coating colors displayed on this product page. These are the only finishes available at this time, although we’re always exploring new options for the future. If a new color gets added to the family, you’ll see it show up here first!

We use your vehicles stock voltage unless requested otherwise.
