Features to know about

Designed for the Powersport Life

Hitting the highway, carving through snow, tearing across the lake - powersport vehicles don't get daily use, and that's exactly the problem. The CT5 Powersport was made for the kind of machines that sit between weekends, road trips, or seasonal adventures. Designed specifically for motorcycles, ATVs, side-by-sides, jet skis, and snowmobiles, it keeps your battery in top shape so your next ride doesn't start with a dead one. You wait all week to ride - this charger makes sure your battery's just as ready as you are.

Keeps Your Battery Ready to Ride

Battery drain happens quietly, and it always shows up at the worst time. This charger stays on top of things by keeping your battery at its ideal level automatically. It doesn't matter if your vehicle is parked for a few days or stored all winter, the charging program handles the upkeep in the background. No switches to flip, no manual settings to dial in - just plug it in, press a button, and walk away. You stay focused on your next ride. The charger handles the details in between.

Revives Batteries That Sat Too Long

Sometimes you forget to plug in. Sometimes the weather turns. Sometimes life just gets in the way - and your battery pays the price. The reconditioning mode is built for exactly that. This function can bring deeply discharged lead-acid batteries back from the edge, giving them a second shot instead of a trip to the recycler. It's recovery when you need it - not just maintenance.

Smart Charging for Lead-Acid and Lithium

Whether your vehicle is running a traditional lead-acid or AGM battery, or upgraded to a modern lithium setup, this charger lets you select for the chemistry. Once you choose the mode, it delivers the correct charging profile without any guesswork. That means better performance, longer battery life, and no risk of overcharging.

Completely Hands-Off

Some chargers need babysitting - this one doesn't. It takes over from the moment you pick the mode you need, automatically handling the charging process and switching to maintenance mode when the battery is full. You can leave it on overnight or for a full season, it'll never overcharge or overthink things. You've got rides to plan - let the charger do the rest.

Safe Charging You Can Trust

Hookups don't always go perfectly, but with built-in safety protections, this charger makes sure they don't ruin your day. It's spark-proof, short-circuit proof, and offers reverse polarity protection. That means if the clamps go on backwards, you're still protected and so is your battery.

I bought this to help maintain my battery health on a few atvs and utvs. So far it works great, I was able to recondition a battery that has been fully drained. Battery seems to be working great now, utv starts no problems.

  • Can CTEK CT5 CT79FR Bring Back Dead Battery At 5.6 Volts?
    We've all been there, Josh, you're not alone! The CTEK CHARGER # CT79FR can sometimes recover low-voltage batteries, but it depends on how far gone the battery is. If its still above around 7V and not heavily sulfated, there’s a good chance it’ll begin the charge cycle. If its dipped lower than that like in your case at 5.6V, the charger might not detect it right away, and you may need to give the battery a quick bump from a jump pack or another charger first. You can use jumper cables...

  • Can CTEK CT5 Battery Charger Be Left On RV's Battery All Winter?
    Hey Scott, absolutely! The CTEK CT5 smart battery charger # CT79FR is designed exactly for that kind of scenario. Its a smart charger that switches to a maintenance mode once your battery is fully charged, so it won’t overcharge or dry out your lead-acid or AGM batteries over long periods. We've had plenty of customers use chargers like this when a trailer/RV is in storage, so it'll work great for that. If you're storing outdoors, just make sure your connections are protected from snow...

  • Can CTEK CT5 Smart Charger CT79FR Safely Charge Lithium Battery With BMS Battery Management System?
    Yes Dena, the CTEK CT5 Smart Charger # CT79FR is fully compatible with lithium (LiFePO4) batteries, even if they have a built-in BMS (most do). This model automatically recognizes lithium chemistry and delivers the right charging profile to protect your cells and maximize lifespan. No add-ons or adapters needed. We’ve had several Casita and Scamp owners using it to maintain Battle Born or Renogy lithium batteries over the off-season. One of our neighbors, Eli from New Braunfels, said his...

  • Comparing CTEK CT5 Powersports Lithium Battery Charger To Older CTEK 7002 Charger
    Great question Kevin, and you're not alone in wondering this. The CTEK CT5 Powersport Smart Battery Charger # CT79FR is a more compact, smarter unit than the MULTI US 7002, but it delivers 2.3 amps max, compared to the 7002’s 7.2 amps. That means it’s a bit slower for bulk charging larger batteries, but it shines when it comes to battery maintenance, diagnostics, and long-term health. It’s fully automatic, works on 12V lead-acid (flooded, AGM, EFB, maintenance-free, CA/CA, and GEL) and...
