Features to know about

Built for Fixed Bays and Fast Workflows

In a busy shop, time matters - and chasing cables or moving gear shouldn't be part of the job. The PRO25SE is made for stationary setups, with a wall-mount bracket and extra-long 19-1/2' cables that reach across the bay without slowing you down. It keeps your charger where it belongs and your space working the way it should.

Delivers Stable Power During Diagnostics

There's nothing more frustrating than losing a scan or bricking an ECU because of unstable voltage. This charger features a dedicated 12V supply mode that keeps voltage consistent through diagnostics and service work. When the job calls for clean, stable power, this charger gives you the confidence to plug in and stay locked in.

Handles Lead-Acid and Lithium with Confidence

From daily drivers with standard flooded batteries to lithium-powered performance bikes, this charger covers the range. It supports lead-acid and lithium batteries. Just select the mode, and the PRO25SE applies a smart, safe charging profile automatically. It's built to match the variety of vehicles that come through your bay, and it does it without hesitation.

Brings Weak Batteries Back from the Edge

Not every battery on your bench is a quick charge away from being ready. Some have sat too long. Some barely click the starter. The Recond mode gives you a shot at recovery, sending a controlled high-voltage pulse to help desulfate and restore capacity in deeply discharged lead-acid batteries. It's a feature that pays off when you're trying to get one more season out of a battery - or avoid replacing one that still has something left to give.

Performs in the Heat and Cold

You don't get to choose the temperature in a shop - and neither does your battery. This charger includes automatic temperature compensation, adjusting the charging voltage as needed to match ambient conditions. That means you get safe, efficient charging across seasons, shifts, and whatever surprises your workspace throws at you.

Safe, Durable, and Ready for the Bay

Fast-paced shop environments don't leave a lot of margin for error - and the PRO25SE is built with that in mind. It's spark-proof, reverse polarity protected, and short-circuit safe, so even if things don't go perfectly, your gear and your battery are protected. The impact-resistant housing and IP44 rating mean it's built to handle daily use around lifts, carts, and concrete floors. It's the kind of tool that earns its place in the bay - and keeps it.

Video Transcript for CTEK Explains: How to Make Your Battery Last Longer

I'm Matt with etrailer. Today, we got Evan here from CTEK. Great to have you. Thanks for having me. We actually have him here for some training so we can get a little bit more hands on with their products. And as he gives us the perfect opportunity to get to know you guys a little bit more, so could you guys really tell us a little bit more about you and what you guys do Absolutely.

So, my name's Evan, I'm the sales manager of CTEK. CTEK has been making battery chargers for over 25 years. That's our only focus. All we do is make battery chargers. So we actually pioneered the technology back in the '90s, and we've been focused on just doing that ever since out of our headquarters out of Sweden.

Awesome, that's great. And you can really tell the care you guys put into it, there's tons of settings, and even the quality when you handle them feels really nice. Definitely. And again, it's all we do. So it's something that we've pioneered over the years, back our products with a warranty that we stand behind, obviously available through etrailer, and that's what we're excited to be training here today.

What really stands out about these chargers, and what kind of separates you guys from the competition Absolutely. For instance, our MXS 5.0 has a small battery mode, which is key for just that reason alone, charging small batteries. If you've got a jet ski, lawn mower, motorcycle, you definitely wanna select the correct mode with our charger. In this case, it would be the motorcycle mode. If you're charging a car truck, the mode next to it for automobiles would be selected for charging just that.

We also have a recondition mode on this charger. Recondition sulfated batteries bring them back to new. And that's actually one of the biggest things I noticed about these chargers is that reconditioning mode. That's so common where you have a vehicle sitting over winter or just a battery in general, and you try to get the start up and nothing happens. Exactly, and we definitely recommend putting a CTEK on that vehicle all season long. It'll never overcharge or boil your battery. It'll simply go into a maintenance mode and you can leave it there for a day or a year. It'll never overcharge. Now, there's plenty of chargers on this table and a common question people have is: How do I know which one is right for me And it's a great question, which can be answered either on ctek.com. We've got a Product Finder, you can select what battery you have and what charger you might need. Or of course, calling etrailer, going online. We do have a wide variety of products, from small chargers for small batteries, up into our Professional Series of chargers, larger batteries that require larger chargers. And that's something I definitely appreciate about you guys. Just that wide category of like you got some for those extreme cold temperatures, you got some specifically catered to the lithium batteries and then your lead-acid batteries, so everyone can just get the most out of that charging. Yes, exactly, and like you mentioned, we do have a polar that is designed specifically for cold-weather charging. And at the same time, we've got CT5 Powersport, and that is specifically for Powersport vehicles, whether it be ATV, side-by-side motorcycle, it will indicate on the charger that it does charge lithium, as well as lead-acid and AGM all in one charger. And I know you just mentioned that you can charge your side-by-sides, ATVs, and plenty of other options besides your regular vehicles, but you can also use these for just your trailers and even motorhomes. Exactly. And the product I would recommend for larger batteries, like you'd mentioned, for motorhomes, et cetera, would be our 7002. So our US 7002 Charger is a seven-amp charger. Does have a AGM setting on there for charging deep cycle or AGM batteries. We'll charge a motorhome battery, a large battery quickly. And again, just like all the rest of our chargers, you can leave it on as long as you like. It will simply go into a maintenance mode once that battery's fully charged, and you can leave it there. All of our chargers do include clamps and islets in the package. That way, it gives you the option to charge your motorhome battery, but then you can also use it on your car truck at home. Matt And actually, speaking of those islets that you can use with it, some of these you can just pretty much keep with the vehicle. You don't have to remove it every time. Yep, included in the package, pilots that could permanently mount on that battery. That way, let's say you're charging an RV battery or a trailer battery, it's always there when you need it, you simply take the CTEK end, plug it in. There's a memory on our chargers if the power ever goes out, it will simply go back to the last setting it was connected to. Now a common question that I've seen a lot is this isn't a jumpstarter, right That's correct. Our lineup of chargers are simply just that, battery chargers meant to charge your battery and then obviously maintain at the same time. Great to know. Now, are there any like really important things that you want people to know or that really stand out about these products The one neat thing about the CTEK Lithium Charger, the fact that it's got a Reset button. So for, let's say, deeply-discharged lithium batteries that will no longer take a charge, let's say you've left your vehicle outside in the winter months, you're unable to start it. You're trying to charge this battery, but it won't take a charge. Simply press and hold the Reset button on the lithium charger for 10 seconds. It will open the battery management system, allowing that battery to take a charge. That's great. Sounds super easy, just a press of a button. Exactly. Well, that about wraps it up. Thanks, again, to Evan for stopping by. Appreciate you having me here. It was great. Now, if you guys have any other questions about any of the CTEK products, you can come by our website, check out any of our videos, and of course, let us know if you have any questions. But again, I'm Matt, and thanks for watching.
