Utilizing patented Pulse Technology, it can extend battery life up to three times while ensuring safety with features like fuse protection and water resistance. Ideal for a variety of vehicles, this charger is a must-have for eco-conscious drivers looking to maximize battery performance. ## Description Product description Restore Your Battery to Peak Performance: Powered by PulseTech’s patented Pulse Technology , this advanced battery repair mode uses cutting-edge Pulse Technology to deliver 25,000 cycles per second, pulsing and effectively eliminating harmful lead sulfate crystals on the battery plates and detecting battery sulfation. This process restores battery health, ensuring stronger engine starts and extending battery life by up to 3 times ! Beyond Maintenance: More than just a trickle charger, PulseTech’s smart battery charger maintainer uses Pulse Technology to prevent and remove lead sulfate buildup. This allows your battery to accept a higher charge and store maximum power, ensuring peak performance. Fully automatic, it operates 24/7 with zero risk of overcharging, making it the ideal solution for everyday use. What makes our battery charger, maintainer & desulfator better? PulseTech’s PULSE technology is a high frequency conditioning pulse recognized to effectively charge and recover weak 12V batteries. This fuse-protected, spark-proof battery desulfator reduces naturally occurring sulfation which increases performance and makes vehicle batteries last 3 times longer without ever overheating or overcharging. Proprietary algorithms, combined with microprocessor-controlled technology, measure the battery's voltage and current to automatically determine the battery's state of charge (25%, 50%, 75% or 100%) and deliver the precise charge rate based on the size and condition of the battery. No guess work! This innovative, state-of-the-art battery charger automatically knows what to do so you don’t have to be a battery expert to use it. You don’t need to select the battery type or the proper charge rate for your car's battery to avoid the risk of unsafe or improper charging. There’s no guess work because the fuse-protected, spark-proof XC400 works on any type of 12-Volt lead-acid battery – VRLA, AGM, gel and flooded. The XC400 automatically determines and delivers the precise charge rate throughout the five stage charge process. Input Voltage: 100-240 VAC Max Charge Current: 4A Pulse Frequency: 40-50 kHz Power Cord Length: 6 ft Main Battery Cable Length: 6 ft Lug/Clamp Cable Length: 2 ft Xtreme Charge is more than a battery charger and maintainer. During the maintenance cycle, PulseTech’s patented, optimized frequency pulsing constantly works to minimize and reduce naturally occurring battery sulfation – the main cause of battery failures. By reducing the size and number of lead sulfate deposits on the battery plates that negatively affect your battery’s ability to accept, store and release energy, your battery will charge deeper, maintain greater reserve capacity and last longer – up to three times longer. The quick disconnect feature allows you to permanently attach lugs to the battery and easily switch between lugs and clamps. The status light column shows you when the unit power is on, pulsing and charging. The battery light column indicates the percentage of the battery’s state of charge: 25%, 50%, 75% or 100%. Adding the PulseTech QuadLink to your XC400 allows you to charge and maintain up to 4 batteries at once If you've ever wanted to maintain four batteries with one charger, QuadLink 4-Channel Battery Charger Multiplier makes that possible. QuadLink turns any 6-Volt or 12-Volt battery maintenance charger up to 8 Amps (using the standard 2-prong output connector) into a 4-station maintenance charger. You don't need to buy three more chargers to do the job. Power is supplied by your connected battery charger. You don't need to spend time or remember to switch your battery charger back and forth between vehicles or batteries in storage. Utilizing a simple plug and play system QuadLink automatically splits and distributes 15-minute charge segments sequentially from battery to battery. Cycle rotation will continue indefinitely. QuadLink Part # 100X004, Model # XC-QL4. Perfect for use on: Use it on automobiles, light trucks, SUV's, motorcycles, motor homes, small boats and watercraft, lawn mowers and equipment, ATV's and even golf carts. Review: My go to charger now. - Bought this because of their pulse technology - supposedly patented - that is supposed to extend the life of your battery by desulphating plates in your battery. I don't have a battery tester, so I can't say if it works or not, but there were enough credible reviews to give me hope. Here is what I do know. The desulphation mode runs automatically and constantly while hooked up to a battery. It runs a test every so often while it is charging the battery, shows you what percentage of charge the battery has, and adjusts the charging rate accordingly. Once it reaches full charge, it will automatically drop into trickle charge mode - but continue the desulphating routine. If the plates gain "new" ability to hold more charge due to having sulphates removed, it will go back into charge mode until it reaches 100 % again, and then drop back into trickle charge mode. I have witnessed this multiple times on the older battery I have in my truck, so I am hopeful that it is indeed cleaning the plates and will make my battery last longer than their usually short life span. Because it constantly works to clean the plates, I have started hooking it up to my truck overnight on the weekends, just to give it a chance to keep the battery plates clean. I have also used this charger on my motorcycle battery as a trickle charger between rides, and it has worked for that also. This is now the only charger I use ( I have others ) and if it does indeed extend my battery life, I will not bother using any other. Review: Great charger - Already fixed my atv battery that sat dead for a year! ## Features - Extended Battery Life - PulseTech uses patented technology to break down sulfation crystals back into the solution of vehicle batteries allowing them to recover, charge deeper and last up to 3x longer! A longer battery life reduces recycling and pollution, making our planet a better place to live. Our unique Pulse Technology has been independently tested by Ohio State University and proven to recover and extend the battery life of 12-volt lead-acid batteries. - The XC400 evaluates the battery during initial connection and tests it continually to determine the appropriate charge rate based on your battery’s current capacity and condition. This TEST step also includes a “Bad Battery” indication if it determines the battery is faulty and cannot be re-charged. - Pulse conditioning provided by PulseTech Products increases performance and life cycles of any size or type of 12V lead-acid battery. - Ultra Safe - Fuse-protected, spark-proof, and water-resistant battery charger. No overheating or overcharging no matter how long the battery maintainer is connected. - Advanced Design - 4-amp battery charger features Pulse Technology. Most battery chargers say their “pulse” loads batteries with a higher voltage charge to break off sulfation in larger pieces allowing amp hours to return to normal. This sulfation collects at the bottom, causing an arc of power to transfer from one plate to another shorting the cell. Our Pulse Technology breaks down sulfation crystals into the solution of vehicle batteries allowing the battery to recover and charge deeper. - In the box - The XC400 battery maintenance charger features a rugged plastic protective case. It comes with an eyelet lead and clip lead. Five-Year Limited Warranty. - Versatile Use: The XC400 battery charger and maintainer is perfect for all land or water vehicles like RVs, outdoor equipment, small boats or watercraft, and automobiles. - PulseTech is an American company with a team of customer service technicians to answer any questions you may have. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C5TQ66FY | | Amperage | 4 Amps | | Best Sellers Rank | #78,029 in Automotive ( See Top 100 in Automotive ) #333 in Battery Chargers | | Brand | PulseTech | | Color | Black and Red | | Compatible Devices | Vehicles (cars, RVs, boats, ATVs, UTVs) and outdoor equipment with 12V lead-acid batteries | | Connector Type Used on Cable | BATTERY_CLAMP | | Current Rating | 4 Amps | | Customer Reviews | 4.4 out of 5 stars 127 Reviews | | Input Voltage | 120 Volts (AC) | | Item Dimensions D x W x H | 7.15"D x 3.62"W x 1.96"H | | Manufacturer | PulseTech | | Mfr Part Number | XC400 | | Model Number | 200x010 | | Number of Ports | 1 | | Output Voltage | 12 Volts (DC) | | Product Dimensions | 7.15"D x 3.62"W x 1.96"H | | Specification Met | ETL | | UPC | 850444004740 | | Unit Count | 1.0 Count | | Warranty Description | Five-Year Limited Warranty | ## Product Details - **Brand:** PulseTech - **Color:** Black and Red - **Product Dimensions:** 7.15"D x 3.62"W x 1.96"H - **Output Voltage:** 12 Volts (DC) - **Specification Met:** ETL ## Images ![PulseTech XC400 Xtreme Charge 4 AMP Smart Battery Charger Maintainer, Trickle Charger | Test, Charge, Condition and Maintain All Types of 12V Lead-Acid Batteries - Image 1](https://m.media-amazon.com/images/I/61HBJgiqCVL.jpg) ## Questions & Answers **Q: Will this desulfate AGM batteries?** A: If you go to their website it states that is does work the same on AGM as lead acid batteries ## Customer Reviews ### ⭐⭐⭐⭐⭐ My go to charger now. *by D***. on July 20, 2024* Bought this because of their pulse technology - supposedly patented - that is supposed to extend the life of your battery by desulphating plates in your battery.

I have been using PulseTech products for over 15 years now and I have seen a improvement in the batteries life span. It is a little on the more expensive end for a battery charger but I can see a long term payback on not having to replace batteries as much. Plus the system does everything just plug it in and connect it to the battery. ## Frequently Bought Together - PulseTech XC400 Xtreme Charge 4 AMP Smart Battery Charger Maintainer, Trickle Charger | Test, Charge, Condition and Maintain All Types of 12V Lead-Acid Batteries - PulseTech XC-Clips Xtreme Charge Battery Leads with Clips - PulseTech XC-EXT 25' Xtreme Charge Lead Extension, 25' --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/536378128-pulsetech-xc400-xtreme-charge-4-amp-smart-battery-charger-maintainer](https://www.desertcart.co.th/products/536378128-pulsetech-xc400-xtreme-charge-4-amp-smart-battery-charger-maintainer) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-15*
