Xtreme Charge XC450 4.5-Amp All-Vehicle 6V/12V Battery Charger, Maintainer, and Conditioner
Model#: XC450
Part#: 300x010
Keep any vehicle's battery in peak condition with the PulseTech smart battery charger. The Xtreme Charge XC450 charges, maintains, and conditions 6- and 12-volt lead-acid, including flooded, AGM, VRLA, and EFB types, and LiFeP04 batteries with PulseTech's patented Pulse Technology to prevent and reverse sulfation, extend battery life up to 3X, and eliminate the worry of dead batteries.
Perfect for cars, trucks, motorcycles, ATVs, UTVs, RVs, and more, the XC400 is maintenance-free, spark-proof, and weather-resistant - making it safe for year-round use, even during long-term storage. Where most chargers offer basic float modes or timed shut-offs, the XC400 continuously analyzes the battery condition and adjusts the output for optimal performance, and transitions seamlessly between bulk charging, absorption, and maintenance, ensuring maximum charge capacity, longevity, and reliability with zero guesswork.
Problems this Product Solves:
- No More Dead Batteries: Keeps batteries charged during long-term storage or inactivity.
- Reduce Battery Replacements: Extends service life by preventing sulfation buildup and over-discharge.

HOW WE 3X BATTERY LIFE
- Patented Pulse Technology: Our unique method removes lead sulfate crystals that cause battery failure, extending battery life.
- Enhanced Charging Efficiency: PulseTech’s systems optimize charging cycles to ensure maximum battery longevity.
- Proven Results: Independent testing shows a threefold increase in battery life, reducing the need for frequent replacements.
- Cost-Effective Solutions: Fewer replacements lead to significant savings in battery costs and maintenance.
The Science of Tripling Battery Life
Founded in 1994, PulseTech is the world leader in recovery, charging, maintenance, and testing of all 12-volt and 24-volt battery systems.
The secret to our success is our patented pulse waveform, which removes and prevents the buildup of lead-sulfate deposits on battery plates. That primes the battery to accept and store maximum power.
For you, this means:
- Peak performance and three times more battery life
- More efficient, resilient, and environmentally responsible equipment
- Freedom, knowing you have the power to go farther and do more.
Long trusted by the military, our tech is ideal for anyone who wants to get more out of their equipment.

WHY YOU NEED A TRICKLE CHARGER
- Prevents Deep Discharge: By providing a steady charge, it keeps batteries from dropping to dangerously low levels, which can shorten their lifespan.
- xtreme charge: Ensures your vehicles batteries are always charged, maintained, and ready when you are.
- Prevents Sulfation: Regular charging helps prevent lead sulfate crystals from forming on the battery plates, which can hinder performance.
- Safe and easy to Use: Designed to be left connected for extended periods, trickle chargers automatically adjust to prevent overcharging.
- Cost-Effective: By prolonging battery life and performance, you save money on replacements and repairs.
I have used PulseTech chargers for about 15 years now. All still work.Two of my vehicles have them on virtually full time when the vehicles are not in use. I regularly monitor voltage, internal resistance, and CCA rating with a high quality tester. All batteries still test as if brand new. PusleTech’s patented approach to charging and conditioning has my vote. The reason for my purchase of the new XC450 was the additional features. I also appreciate their longer warrantee and helpful tech support versus what I’ve seen from other sources. Just a first class product line!
SP-3 3 watt solar charger.Best $100.Ive ever spent.You’ll thank me later.
Don"t lose sleep wondering if your battery will crank your vehicle on a cold winter morning. Charge/maintain it withe the Pulsetech XC450
I like the feature having to select & start push buttons after I hook up the terminals instead of the charging beginning when circuit is completed. It does a wonderful job of restoring batteries. I put a higher amp charger on for the bigger storage batteries if this one does not get it restored & then switch back to the Xtreme to let it fully condition it.
When the power goes out the unit stops charging. It resets to starting mode which is no charging. you have to pick battery voltage, type of battery and then hit the start button. You can't put this on a battery and leave town. If the power goes out, it will stop charging. If this is newer tech, the older unit is better. I have 2 of the older units, and this one of the newer.
