Best-in-Class Battery Recovery: XC400 - test, charge, condition and maintain all types of 12V lead-acid batteries.

Conditioning and Maintenance: Most chargers look at battery voltage only when it comes to charging. Utilizing highly capable software and microprocessor, we consider the multiple parameters that effect charge acceptance over time and deploy the proper processes to not only fully recharge your battery but also desulfate it for improved performance and maintain it properly for extended periods as needed to extended its usable life.

The Xtreme Charge XC400 is truly different. As a trickle charger, it gradually supplies power to batteries, preventing them from losing charge when not in use. Our patented high-frequency Pulse Technology gently desulfates the battery plates by breaking down sulfation crystals, allowing the micro-particles to flow back into the battery’s solution. This primes the battery to accept a deeper charge, perform better, and last up to 3x longer.

Durable and Reliable: Features a rugged and protective plastic case, is splash and dust resistant and comes with an eyelet and clip lead for easy, multiple uses. Five-year limited warranty included. Outdoor Equipment XC100, XC 100, XC400, XC 400, Xtreme

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.

Long trusted by the military, our tech is ideal for anyone who wants to get more out of their equipment.


A trickle charger is a device that gradually supplies power to batteries, preventing them from losing charge when not in use. By charging at a slower and steady rate, trickle chargers ensure batteries never become completely dead and can be left connected for an extended period without overcharging. Just into an electrical outlet and it will do the rest - maintaining charge levels, preventing sulfate build-up, and ensuring peak performance.

Xc400 update

I purchased and started using early November on a vehicle with 2 batteries as it has Ess. I had already had another brand charger tender burnout. I then decided to try this military approved xc400 after a phone conversation. It is now the last day of November and an update is in order-- as I mentioned in another post, the charge times seemed to decrease, after 3+weeks of overnight connection, tonight after 7 minutes, the charge went from initial 25%/bulk to 100% bulk and intermittent bulk. The xc400 itself went from warm in the beginning to barely any noticeable temp change. The xc400 has indeed enlivened and desulphated these batteries and brought their condition back to as good as CAN be! Kudos to the engineering and the engineers in their development of this. I have no doubt to the integrity of the entire line of products offered by this company. Thank you.

XC 400

I’ve been using various Pulse Tech chargers since 2014. Four consumer grade models, 3 X xtreme 100’s, and a X2 xtreme Dual station. They keep my car collection always ready to start. On our business side our diesel equipment heavy trucks, tractor's and tracked crawlers are kept battery ready by Pulse Tech Military Professional grade multi-chargers.

I recently purchased this.XC 400 to replaced a “as new” factory Mercedes Benz Trickle Charger on a new car.

Why? Because the Pulse Tech proprietary technology just works, a recent DOD USMC HMMWV surplus rebuild purchased had sat for 10 years with 1 mile on odometer. The once new batteries were dead dead I expected a replacement purchase would be needed and told so. It took 2 days on the Pulse Tech brought both back to life, that was a year ago zero issues since.

Trickle battery charger.

Sounds like the same thing that harbor freight sells for less than half of what you charge.danl
