Product InformationStore Part Number: XC100-P


Xtreme Charge is well-suited to both AGM and other maintenance free batteries. The combination of patented pulse technology and the patented charging algorithm will typically allow it to more completely charge all regular and high performance batteries, while also maintaining an excellent charge profile suitable for other types of flooded or standard batteries.

Pulse Tech’s unique technology will increase the duty and life cycle of all sizes or types of 12 V lead acid batteries by minimizing the size and amount of sulphation on the lead plates, therefore allowing the battery to accept as much charge as possible.

The XC 100-P patented pulse will help new batteries stay in as new condition, as well as improve older batteries’ charge capacity back up to as new standards. You can expect duty cycles to be extended 3-5 times over similar batteries charged on a standard charger.

This charger is suitable for all 12-Volt lead-acid VRLA, AGM and flooded batteries.

Xtreme XC100-P
Pros: Charges just about any 12V rechargeable battery. No prior experience or even tech inclination required. Simply connect the alligator clips and you're on. Good indication of status but the green LED's can be a seen clearly only when you directly over it.
Cons: It did not seem to do diddly squat to the specific gravity of the battery. The two batteries I charged to 100% with the XC100-P had a pre-charge SG at around 25%. This figure remained the same even after 100% charge i.e. although fully charged, the battery continued to be defective. If the manufacturers claims were true the above should not have been the case. I also observed that the after the initial test, the battery indicator starts of with 25% and this it seems to do irrespective of real status of the battery (I tried charging a new 12V fully charged car battery).
I would have loved to see some indication of actual recovery taking place. It should be fairly straight forward to correlate voltage levels to oxidization levels. If the pulse thingi removes the oxidization then obviously the voltage and Amps will improve. Without any kind of indication about this, I'm not sure the XC100-P is actually doing the trick.

Good Stuff
Pros: I looked into my car battery and noticed that the plates were covered with sulfation. (gross!) I know that is the cause of early battery failure, so I feel good that the XC100-P is constantly sending pulses to help restore my battery. It's not dead yet, but I want to make it last as long as I can.
Cons: The unit is very nice and easy to set up. No cons here.
I like the ability to use the ring terminals and leave them on the battery. Every time I need to use the vehicle, I just disconnect the adapters, and tuck in the little cable inside the hood.

Good but not the best
Pros: I purchased the Pulse Tech XC100-P and the Battery Minder 12248 "smart" chargers at the same time so that I could test and see for myself how smart these chargers really are. Both chargers appear to be top quality designs and if they perform as advertised then they should repay the purchase price in extended battery life or recovery of sulphated batteries - if you have some. Since I have a variety of flooded wet cell and std. AGM batteries that I use all the time it was easy for me to make back-to-back comparisons between the two chargers in Bulk, Absorption and Float stages. I have no way to tell if either are able to reduce or eliminate most sulphation other than if I see longer battery life from all of the batteries I use them on. That will take years to determine and even though Battery University states that there isn't enough documented independent testing to confirm the high frequency pulse de-sulphation claims, I'll give these two companies the benefit of the doubt and see what transpires in my long term battery testing. I am however concerned about the statement on the XC100-P being "very suitable" for all lead acid batteries because of it's "smart" technolgy. The issue is can the XC-100P really tell if a battery is a std. flooded wet cell or a maintenance free calcium lead (auto) type battery or a std. AGM battery or a gel cell battery or a special AGM battery like an Optima or Oddysey? The reason this is important is because thes batteries require different Absorption and Float voltages to be fully charged and not under or over charged. My testing proved quite interesting. Read on in "Cons"...
Cons: The Pulse Tech XC100-P caused me some concern when I found the float voltage on a 12 Ah 12v AGM battery to be 14.25v when it should only be in the 13.4-13.6v range. Anything above this for a std. AGM battery is considered excessive and it will certainly hurt the batteries life as documented by many battery makers. I ran the test multiple times and the XC100-P simply is not appropriate for these smaller std. AGM batteries and could easily "cook" them if left on 24/7. Next I tested the XC100-P on a 18 Ah std. AGM battery. On this battery the Absorption voltage was on the low side and the float voltage within the proper range. Next I tested the XC100-P on a group 49 flooded wet cell automotive battery. On this battery the Absorption and Float voltages were within the proper charging ranges as specified by the battery maker. Next I tested the XC100-P on a group 94 maintenance free automotive battery. The Absorption voltage was acceptable but the maintenance voltage was too low. As a result of my testing so far I would say the XC100-P is a good battery charger/maintainer for larger std. flooded wet cell batteries. It is definitely less than ideal at charging maintenance free calcium-lead batteries to 100% full charge in my testing to date. It definitely is not acceptable at all for maintaining 12 Ah or smaller std. AGM batteries. It also may not be able to fully charge the Optima or Odyssey batteries to 100%. Bear in mind that there are subtle differences in AGM battery contruction and some batteries like Optima and Odyssey in fact require a higher Absorption and Float voltages than conventional std. AGM batteries. Knowing what I now know from my testing, if I had to do it over again, for my needs I would buy another Battery Minder 12248 and not the Pulse Tech XC100-P, which might be fine for other people's needs, but not the variety of batteries that I need to maintain. I suspected that the "smart" technology really could not sense what the battery type was and I think this was proven out in my testing. Other people's results may differ but this is how my XC100-P performed. Continue on to "Other Thoughts"...
Battery manufacturers publish the correct Bulk, Absorption and Float charging specifications for their batteries. As noted over-charging in particular can kill the life of a battery quickly. Under charging allows sulphation to occur even with high frequency pulse signals designed to remove sulphation.

It's worth noting that the Battery Minder 12248 is a more comprehensive battery charger/maintainer. It allows you to select the battery type - Flooded Wet Cell, AGM or Gel and also the charging current - 2-4-8 amps. What I found in my testing is that in the same tests that I ran on the XC100-P, the Battery Minder 12248 supplied the correct Absorption and Float voltages in ALL CASES. I attribute this to the fact that you can manually select the proper battery and the charger thus delivers the correct voltages for that battery type regardless of size in Ah. The Battery Minder 12248 never supplied excessive voltage even on the small 12 Ah AGM battery so to me the 12248 is the better charger for those who have a variety of battery sizes and types to charge and maintain.

The Battery Minder 12248 cost more than the XC100-P but it also performs far better IME. The price difference is far less than 1/2 the price of almost any battery of 12 Ah or greater. Most importantly it doesn't "cook" a battery with excessive voltage.

Battery Minder makes a fixed 2 amp. charger/maintainer model 2012, similar to the XC100-P and priced the same or less. I have not tested this charger. They also sell a model 1500 for ~$55. which is a 1.5 amp charger/maintainer. I have not tested this charger. The 12248, 2012 and 1500 models all have automatic Voltage Temperature Correction which is important if your battery is outside or in temps other than in the mid 70 F range. This can be very important.

When the battery/ambient temp goes lower you need to increase the Absorption and Float voltages to have a 100% fully charged battery. When the battery/ambient temp gets above the mid 80 F range you need to lower the Absorption and Float voltages to prevent damaging over-charging that kills batteries prematurely. Unfortunately the XC100-P has no temperature compensation. Since I planned to test it in the 70 F range that was not a concern but for those who might be charging an auto, marine, or other battery outside in hot or cold temps, temp compensation of the voltages is Very important and the only means to have a 100% charged battery that isn't overcharged and damaged. Battery makers specify the importance of correcting battery charge voltages based on the battery/ambient temp.

The more you know about the proper charging voltages for your batteries, the easier it will be to make an educated purchasing decision on what charger works best for your needs.

Pulse Tech 12V 2.5A Battery Charger
Pros: So far, they do seem to help prolong a lead acid flooded cell and sealed lead acid (manufacturer doesn't say the exact type) battery's life. So over time, these will save you money.
Cons: The green LEDs are so difficult to see in some lighting situations, it's ridiculous. They are difficult to see, in particular when looking at the units at an angle in normal lighting situations and therefore it can be hard to tell what's going on concerning the operation. In bright light, it is basically impossible to see the green LEDs. I have never used equipment with LEDs that are this difficult to see and I have used various test equipment, repaired and used various equipment in manufacturing and in hospitals. The manufacturer stated something to the effect that the LEDs' brightness is according to industrial standards. I know of no such standard. Some of the units have failed and it took longer than expected to receive replacements. So far, the last ones I've received are still working ok.

Pulse Tech 12v charger
Pros: When I sold my 82 F150 a couple years ago, I had a Yellow Top battery in it at the time. I had written the date of insulation on the battery and also for the last two yrs I was using the Pulse Tech Restorer. Well, the battery was 11 years old when I sold the truck!! Great service I would say! But I have also used it on completely "dead" 6 volt battery's and they were brought back to life for additional 2 more years.
Cons: ZERO

Excellent charger
Pros: Great charging profile. We maintain Yuasa and Odyssey batteries with this charger and when the batteries are ready to be used, we use a 100 amp carbon pile load test on them and the normally come out at almost double the CCA rating. I have also brought two AGMs back from the dead using this charger in conjunction with a bulk charger.
Cons: NONE.
The price is hefty however, you get what you pay for and this charger is most certainly worth the extra money.

Pulse Tech XC100-P makes a difference
Pros: after a few days on this charger the battery on a 97 Toyota seems to be turning the starter faster than before. the battery on my 87 Honda, which has a re-engineered charging system that is barely acceptable in city riding - has been holding up a bit better than before i started using the XC100
Cons: price

You must have this
Pros: Well constructed and easy to use. This charger is not only smart it's practically a genius. If you hold the unit to your ear you can hear the desulfation pulses that range from rapid frequent pulses to slow occasional pulses. The intelligent circuity gives this unit the ability sense battery condition and set the required parameters accordingly. It has in fact already paid for itself. The float charge VS trickle charge that cheap chargers have works perfectly. You get what you pay for and this is worth paying for.
Cons: Not really a con here but when I originally hooked the charger to my neglected 2010 F150 battery it tended to run hot so I pulled out my antique 10A charger and brought the battery to a decent charge because I don't want to over work this gem of technology and send it to an early grave. The unit comes with battery clamps and 1 ring lug quick connect. I think they should provide a couple more ring lug connectors for other vehicles which can be purchased for about $7 each, but I am cheap that way.
Actual results: Harley Davidson $200 AGM battery (wow) was putting out 12.25V after being fully charged and left to sit for 12-24 hours. After only a total of about 48 hours on the charger my battery holds 12.8V with a steady drain from the battery. My neglected 2010 F150 battery was holding a 12.4V charge over night, after only about 15 hours on the Pulsetech it now holds 12.9V over night. They say desulfation takes 1 day per pound of lead on average so I'm looking forward to more improvement as I shuffle this charger around. I would recommend this charger to anyone.

Excellent Investment
Pros: -Very easy to use. -Warning lights alert you in event of polarity reversal. -Price is great, especially when compared to other similarly capable chargers.
Cons: None so far and none foreseen!!!
I've owned mine for almost a year and can't imagine not having it around. While I cannot (yet anyway) speak for the added lifespan given to batteries, I can say that it will take a battery that was on the way out and revive it.

The reason I purchased the Xc100 was my Optima Red Top, I couldn't get it or keep it at full charge with any other charger and figured I was destined to replace the battery which was less than 3 years old. After using this charger, I now achieve 100% charge and hold that charge much longer than when it was new. I have no doubt that this battery will last much longer with regular "maintenance" charging cycles on the Xc100 that what it would with a standard charger.

My other "problem" battery was a conventional lead-acid battery that would struggle to start my pickup after sitting more that 24 hours. After using the Pulse Tech charger for one week at first and then a couple hours every other month, the same battery is still in use and gives me no issues.

Pulse Tech XC100-P
Pros: All our cars now run AGM batteries. The pulse tech works well on them. I really like it's bad battery light. Thhis feature let me know that the factory battery in my '09 Mustang had run it's course.
Cons: None so far.
I did almost buy the $200 otima charger from another source. It seems to have even more features. However, the pilse tech seems to be filling my need.

Great battery charger
Pros: This charger is a great product. I bought the extra 25' charge-cord extension, and I can charge either car battery with the important charging parts locked away in the garage, while an extension charge-cord runs under the closed garage door to the car battery itself.
Cons: No cons that I can see.
The extension cord for the charge-cord is a must, if you want to charge a battery which is outside the garage sitting under the hood of the car, and the charging component is locked safely inside the garage next to an electrical outlet.

test case confirms Pulsetech units works
Pros: works on every wet-cell and agm battery i have great tech support at Pulsetech 5 year warranty that they live up to
Cons: none
i have owned several units for several years.
Pulsetech has replaced 2 w/o any hassle.
i keep these units on 24x7 on 3 vehicles
i had an old aoutomotice battery that was self-discharging in 3 weeks - probably due to sulfation.
this charger kept that battery going for a year and a half !

Pulsetech Battery charger
Pros: A great charger for smaller batteries and maintaining larger ones. This charger has an informative array of indicators to inform the user of the state of charge, tell you when the battery is fully charged or tell you that the battery is completely dead and unable to take a charge. It's rugged and waterproof. When the battery if fully charged the charger monitors the battery voltage and will automatically recharge when necessary.
Cons: Can't think of any.
This is like a Deltran Battery Tender, except it has more indicators, slightly higher charge rate and its water proof. Pulse Tech states this charger has a pulse function which will slow sulfation during extended float periods.

Love it, Works Great
I like this Charger/Restorer so much that I bought 2 of them for my solar system Batteries, they brought my batteries back up to like new condition again. I like the fact that it has a Gauge to measure the condition of the battery being restored from 25% to 100%

Quite simply the best there is!
I have been using Pulse Tech chargers for years and they just work at keeping sulfation down! Lots of copy cat charger, but these are the best!
