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.

Xtreme Charge® XC400 4-Amp Battery Charger/Maintainer
Your pulse conditioning keeps my batteries fully charged and extends their useful life to about 10 years. With over 12 batteries to maintain, this explains why I have so many of your chargers...they work!

The charger itself and the cabling are fine. The led indicators seem to cover all the bases - at least for the one AGM battery that I used it on. As the directions stated, I connected the charger first to the battery and then plugged in the AC power cord (same sequence in reverse for disconnecting the charger from the battery). The XC400 lacks what every electrical appliance device in existence has - an On/Off Switch. This I think would be particularly useful if you leave it plugged in on a bench in the winter like I do to charge various yard equipment batteries. I hope the AC line plug lasts and doesn't fray off he cord being plugged/unplugged so much. A switch like my older Shumacher chargers has - 2A/4A/Off selector 3-way switch would be a great improvement.
Secondly, I'm a bit concerned about the heat the unit produces when connected to a fully discharged battery. This thing gets HOT! In a fully enclosed plastic case, I'm not sure how long the electronics will last due to the pizza oven effect? I'm thinking of mounting it on a finned aluminum heat sink to draw some of the heat away when charging. I worked 30-yrs in electronic design as an engineer and I know what I'm talking about.
my effort at using an alternate source battery minder ended killing off two batteries. The model I had chosen could select from glass matt, flooded or gel style maintenance. It broke stuck in gel mode possibly from power company glitches and gel mode I think misstreated the flooded cell batteries until they only regsitered 9v. So, two new batteries and using the XC400 gives me confidence I will not have another misstreatment battery loss. Its stays in one mode, flooded.
Love these charger/maintainers.Work great for my needs
