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.

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 D5100R with reversed polarity

The XS Power D5100R deep cycle 12-volt battery provides up to 3,100 maximum amps and has a capacity of 66 amp-hours. Reversed terminal polarity allows it to work in a number of popular vehicles. A reinforced plastic case protects it in your vehicle. Check "Accessories" for items that'll help you install and secure your new battery. This reversed polarity battery means that the terminals are on the opposite sides compared to the standard version of the battery.

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 advisors.

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 D5100R

Product Research

Features

Overview: The XS Power D5100R 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.

Note: The D5100R is reverse polarity, meaning the terminals are on opposite sides (left is negative, right is positive), compared to the standard polarity battery. For standard polarity, see D5100.

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 AK2500, can be used to connect the D5100R in parallel (+ to + and - to -) with the main battery.
  • OEM Battery Replacement: The D5100R fits the BCI Group 51 vehicle applications and will fit many small imported vehicle 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 5100 Billet Aluminum Hold Down (#548) 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 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 D5100R has the following specifications:

  • MAX Amps: 3100 amps
  • Cranking Amps (at 32°F): 872 amps
  • Reserve Capacity: 131 minutes
  • Discharge Capacity: 66 Ah (amp hours)
  • Dimensions: Length=9.04", Height=8.19", Width=5.43"
  • Weight: 43.2 pounds

Q
What gauge big 3 should I upgrade to when I install this?
stephanie  Nov 01, 2023
1 answer
A
Selecting the gauge for a Big 3 upgrade is more so dependent on upon the needs of your aftermarket audio system's amplifiers. Under 1500 watts RMS, you can use a 4 AWG Big 3 kit. Over 1500 watts RMS, we would recommend a 1/0 AWG kit.

robert  Feb 06, 2022

Used for starting car and car audio 900 amps on birthsheet 1100 2 subs jlaudio 10 inch 4 70amps doors speakers Did great. But better if u have a separate this battery just for car audio and another for starting car. Upgrade power cables. And tbh 2 -10 inch 3000 amps kinda hard to believe. Prolly pushing my setup amount. 1100 amps. If its not rockford or jl audio. I won't believe those specs.
leandro  Feb 06, 2022

Reach out to Xs power for your specific application there is a lot more to what someone would recommend that they would need to know, like if it's a starter or secondary battery and if it's the up front battery what vehicle you have etc. I would most likely recommend a bigger batter for a 3k system!
james  Feb 05, 2022

Upgrade your alternator.
michael  Feb 05, 2022

Q
What is the idea behind using a reverse polarity battery as opposed to standard polarity?
jeremy  Mar 09, 2021
5 answers
A
It is car specific. it's determined by where and how long standard positive cables for your vehicle are usually the layout is reserved for import vehicles.
antonio  Mar 09, 2021
A
It is to match the correct side that your vehicles positive and negative wires are run on. That ensures that the factory wires reach the terminals properly. You match it to the factory battery setup. The batteries are exactly the same other than the positive and negative being on the other side.
anthony  Mar 09, 2021
A
There's no idea behind it. Some cars have the positive cable in a reverse direction which requires the positive to be on the other side.
anthony  Mar 09, 2021
A
Depends on the location of the terminal set up in your car.
morris  Mar 09, 2021
A
It depends on what you are using the battery for. My cars wiring under the hood dictates what type of polarity is needed. My second battery in the trunk doesn't matter because the negative is grounded and the positive comes directly from car battery.
jose de la  Mar 09, 2021
Q
Does this battery come with terminals or will I need to buy the short brass or tall brass terminals?
jeremy  Oct 13, 2019
7 answers
A
It does not come with terminals. I bought the short brass ones that XSPower recommends and they work great.
nathaniel  Oct 14, 2019
A
You'd have to buy the terminals separate... And which ones depends on how much clearance you have when the hood is shut and or what you plan to strap onto the terminals.
khaalid  Oct 13, 2019
A
No, it doesn't come with the post type terminals.
nathaniel  Oct 13, 2019
A
The short or tall terminals do not come with the battery. Only the M6 bolts and washers come with it.
gary  Oct 13, 2019
A
You need to purchase those separate. They are around $9.99 which u can also get from crutchfield. "Pair of 12-volt battery terminal posts (model PN 580)" is what i got and those work perfect.
richard  Oct 13, 2019
A
This can be found on the details tab of the product. "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:" This battery is a reverse polarity battery, so pay attention to what version you need for your vehicle and consult the Crutchfield navigation or support to determine the optimal battery for your car.
joshua  Oct 13, 2019
A
Youll need terminals
