Vintage styling, XS Power

XS Power heard your requests. Their A3400 deep cycle 12-volt battery comes in an all-new vintage-styled case that'll fit in with the styling of any hot rod or custom vehicle, while delivering up to 3,300 maximum amps and a capacity of 65 amp-hours. Now you can have the power you need with the "right look" for your ride.

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. No leaks mean no 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.

Need more help choosing the right battery for your vehicle?

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: You must charge this battery before installing it. We recommend XS Power's HF IntelliCharger (sold separately) to charge this battery properly. Improper charging can permanently damage the battery, and void your warranty.

More details on the XS Power A3400

Mark G.

Product Research


Overview: The XS Power A3400 12-volt AGM battery is a six cell, sealed-valve regulated, lead-acid battery designed to replace your OEM battery, supplying more power to the vehicle and especially larger audio system. Included with the A3400 are two M6 bolts with lock-washers for attachment. As part of XS Power's Vintage series batteries, the A3400 is styled to look "antique".

Terminals Needed: This A-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).

OEM Battery Replacement: The A3400 fits the BCI Group 34 vehicle applications and will fit GM vehicles applications. For vehicles with side-post terminals, an i-Bar (#551, #555, #556) can convert the top terminal into a side terminal, and provide terminals on the top for connecting your amplifier power. 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 3400 Billet Aluminum Hold Down (#573) 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.

At this time, XS Power's fit guide only goes up to 2012 so, I called them to confirm. The tech I spoke with said this A3400 model will physically fit but the terminals are on the wrong side for your application. You're welcome to try and see if your cables will reach but you may need an extension. He recommended the D3400 model instead: I hope that helps! My Bio:
