WHY YOU NEED A TRICKLE CHARGER
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.
WHY YOU NEED AN ANALYZER
Battery analyzers provide crucial insights into your battery's health, helping you stay ahead of potential issues and keep your equipment running smoothly.

WHY YOU NEED A RECOVERY CHARGER
Perfect for users with a variety of lead-acid batteries, these devices autonomously manage the charging process to ensure optimal battery health. Designed for portability and ease, they're the ideal solution for battery rejuvenation, wherever and whenever you need it.

Xtreme Charge 4Amp Battery Maintainer Charger

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.

The new pulse tech maintainer is great this is my third one to buy not because the other ones quit working, I have 2 out in my shop building for all my toys and just bought the new one for my garage I have 2 vehicles that barely get driven and the batteries are always going bad.

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.

Man the absolute BEST customer and tech service so happy with the purchase

Great

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

Bought 2 Epa150-24 aka xoo1K3w5x7 24 volt chargers one failed right off the bat. Can't get anyone to answer my request for warranty replacement.

Xtreme Charge 4Amp Battery Maintainer Charger

In using this for 5 days, I have seen the bulk times shorten, the time it takes to reach 100% has shortened as well, I can tell by feeling the top case that the charge currents appear to be lessening as the unit is running cooler. So far , so good. Impressed thus far. I'll update in a month as the desulphation should have happened on a more complete basis. Kudos to the engineers on this!!

Works like a Charm. I needed a Battery analyzer to check the Solar Batteries and this does just that… Thank You

Failed in two months. Plastic covered wire is the failure point, plastic is to brittle and should be rubber coated.

Best charger I have had thx so much
