Features to know about
Keep Your Battery Ready for Freezing Mornings
You know that slow, dragging crank when your car or small tractor has been sitting outside all night in the freezing cold? Low temperatures reduce the power your battery can deliver, and starting an engine becomes even tougher when everything is cold. This 50-watt Zerostart blanket wraps around the battery and warms its core to 60°F to 70°F above the surrounding temperature. That warmth helps maintain available cold cranking amps, giving your starter more power to work with when it's time to fire up the engine. It's useful for cars, UTVs, compact tractors, and other equipment parked outside or in unheated buildings through the winter.
Keep the Warmth Where Your Battery Needs It
This 28" blanket fits smaller batteries, including Groups 22NF, 26, 51, and 70. The flexible wrap surrounds the battery case, while Thinsulate insulation helps retain the heat. An adjustable strap keeps the blanket snug around your battery. It's a practical setup for a single battery in your vehicle or equipment, including a small tractor that sits in an unheated barn. If your battery needs a longer wrap, check out the 36" Zerostart battery blanket (ZE87FR) for larger battery groups.
Before choosing this heater, check your battery group and measure around the case to make sure the blanket fits without folding or overlapping. Don't cut it to length or install it over an existing thermal blanket, since these arrangements can create hot spots. It's also important to check your battery construction. This heater is not recommended for lithium-ion, nickel-cadmium, or batteries with ABS cases.
Plug In Before the Temperature Drops
Once the blanket is secured, the grounded 30" cord connects to a standard 120V household outlet. This works well when your vehicle is parked beside the house or your equipment is stored in a garage or barn with electrical service. The heater uses just 50 watts and is CSA-certified.
One thing worth knowing is that this model does not have a built-in thermostat. It continues heating whenever it's plugged in, so you'll need to manage when it runs. A compatible external temperature-controlled switch (sold separately) is one option for controlling power during cold weather. Also, remember to disconnect the power before driving away.
Cold-Weather Experience Behind the Zerostart Name
Zerostart is a brand of Phillips & Temro, a company that also develops engine-heating products for vehicle manufacturers. So even if the Zerostart name is new to you, your battery blanket comes from a manufacturer with experience helping vehicles handle cold weather.

When I first tested out the Zerostart Heating Pad, the first thing I thought was, wow, this thing gets hot. It’s definitely built to warm up a battery in harsh, cold conditions, and I’m really looking forward to trying it out once it starts snowing here in Missouri. A lot of people compare these to the KAT’s heater line since they’re pretty similar products, but what really stood out to me was Zerostart’s customer service. I emailed their tech line with a few questions, and they got back to me within minutes that kind of support makes a big difference

Well, installation was easy and the cords are long enough to reach useful places. I'd love to send pictures, but the blankets are covered by another layer...

See what our Experts say about this Zerostart Vehicle Heaters
- Is There A Heater Pad To Keep Lithium Batteries Warm In Cold Winter Weather?Hey Wes, I’d avoid it. All of the battery heaters we carry, such as the 50w # ZE77FR, 80w # ZE87FR, and 160w # ZE27FR Zerostart pads, are not recommended for lithium-ion batteries because they heat too directly on the case. Lithium cells need controlled, internal heating. Look for a lithium-specific warmer or battery with built-in heat instead. Some (mostly higher end) lithium batteries actually have an internal heater or self heater to take care of that. At minimum, most lithium batteries...
view full answer... - Can I Start Truck While Battery Heater Is Still Plugged In? - Maintaining Batteries In WinterYes Deedee, you can crank the engine with the heater plugged in (it doesn’t interfere electrically). Just remember to unplug before driving off so you don’t damage the cord. Many owners route the plug near the grille for easy access so they can run an extension cord to it, and easily disconnect and drive off. What heater were you looking into? We have some sizes for common batteries such as # ZE77FR for group 22NF, 26, 26R, 51, 51R, and 70 batteries, # ZE87FR for group 24, 24F, 24H, 24R,...
view full answer... - How Long Is The Power Cord On ZeroStart Battery Heater Pads?Good morning Ken! The battery heating pads from Zerstart, such as 50W # ZE77FR, 80W # ZE87FR, and 160W # ZE27FR, all include a 30-inch grounded cord. It’s long enough to reach the edge of most hoods or generator compartments, but you can safely use an outdoor-rated extension if needed. Are you planning to plug in through a timer or direct outlet? Most people route the cord to the grille, then use an extension cord to plug in overnight.
view full answer... - Can I Use 2 50W ZeroStart Heater Pads To Keep 2 Small Batteries Warm In Polaris Ranger UTV?Yes Ron, that’s a solid plan. Two # ZE77FR pads will keep both batteries warm without drawing much power - only 50 watts each. Wrap them individually so the heat’s even, and you’ll avoid sluggish starts in snow season. Do you park your Ranger inside or outside overnight? And out of curiosity, what is the second battery used for? A stereo or sprayer or something?
view full answer... - What Kind Of Warranty Does Zerostart Battery Heater Come With?Megan, every Zerostart heater - the 50w # ZE77FR, 80w # ZE87FR, and 160-watt # ZE27FR - comes with a 1-year limited warranty and full CSA safety certification. They’re oil, acid, and heat-resistant, built to last season after season. Have you used Zerostart gear before, or is this your first time getting your setup winter-ready?
view full answer... - Can I Leave ZeroStart Battery Heater Pad Plugged In 24/7 During Winter?Marissa, you sure can - these Zerostart pads are built to stay plugged in through a cold spell without any problem. Just keep them running only when it’s below freezing, since they don’t shut off automatically. Once the days start to warm up, unplug or put them on a timer outlet so your battery doesn’t get overheated. How long do your cold snaps usually last where you’re at? If all winter is below freezing, there's no reason you can't just leave it plugged in during the entire cold season....
view full answer... - Will 50W ZeroStart Heater Pad Be Enough To Warm Up Small Tractor Battery In A Barn In Montana?Dale, the 50-Watt Zerostart Heater Pad # ZE77FR is a great choice for small tractor or compact equipment batteries. It fits Group 22NF, 26, 26R, 51, 51R, and 70 sizes and keeps them roughly 60F warmer than the outside air. For Montana winters, plug it in overnight when temps drop into the teens and you’ll see much easier starts in the morning. Do you have power at the barn, or will you be running it from an extension cord?
view full answer... - How Much Power Or Amperage Does The Zerostart 50W Battery Heat Pad Draw?Smart planning, Alex. The Zerostart 50-Watt # ZE77FR draws only about 0.4 amps at 120 volts, so even running several won’t overload a 15-amp outlet. They’re great for smaller batteries like Group 22NF, 26, 26R, 51, 51R, and 70 batteries. Are you setting these up on a fleet or a few machines around the property?
view full answer... - Can I Use A Battery Heat Blanket In A Plastic Battery Tray?Yes, Carla - the Zerostart 50-watt battery blanket # ZE77FR is fully insulated and CSA-certified, so the outer layer stays cool enough for plastic trays. Just make sure it sits flat and the cord exits cleanly. It’s ideal for smaller setups like powersports or car batteries, or some smaller RV batteries (total length is 28"). What are you installing it on, something you use daily or just in winter?
view full answer... - Recommended Battery Blanket for a 2015 Ford F-150Hey Steve. For your 2015 Ford F-150, you'll want the Zerostart Battery Heating Pad - 120V item # ZE77FR. This 28" long heating pad will wrap around your battery to warm the battery's core to 60-70° above ambient temperature. It is designed to work in sub-zero temperatures and is powered by a standard 120v grounded plug with a 30" cord. What are the dimensions of your F-150's battery? We also have a longer item # ZE87FR which is 36" long but you can't overlap it. You can add this information...
view full answer... - Do Zerostart Battery Heat Pads Have Built-In Thermostat Or Timer?Good question Zane. None of the Zerostart battery heating pads include a thermostat. They provide constant, steady heat whenever plugged into 120V AC, so it’s best to run them on a plug-in timer or a thermo-switch that kicks on below 32F or a timer that kicks on during the night when it's coldest. That gives you automatic control and extends pad life. Have you already got a timer in mind? Also, what size battery do you have? Here are some options to look at: - # ZE77FR for group 22NF,...
view full answer... - Can I Use 50Watt Zerostart Battery Heater Blanket In A Damp Garage? GFCI Needed?Yes, Dana - the Zerostart 50-Watt # ZE77FR is sealed against moisture and CSA-certified for safety. Normal condensation or damp air won’t hurt it, just don’t submerge or spray it directly. It’s designed for harsh conditions and built to last through years of winter starts and it's heat, oil, and acid resistant. Is this for a vehicle you drive often or one that sits through the season? One tip I'll also throw out there is to make sure you have it plugged into a GFCI receptacle that shuts...
