Features to know about
Keep Your Battery Ready for Freezing Mornings
You know that slow, dragging crank when your truck or car 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 80-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, pickups, RVs, and equipment parked outside or in unheated buildings through the winter.
Keep the Warmth Where Your Battery Needs It
This 36" blanket fits several common battery groups, including Groups 24, 27, and 31. The flexible wrap surrounds the battery case, while Thinsulate insulation helps retain the heat. An adjustable strap with a snap buckle keeps the blanket snug around your battery. It's a practical setup for a single battery in your vehicle or equipment, including an RV battery in an unheated compartment. If you have two batteries positioned close together, check out the 72" Zerostart battery blanket (ZE27FR) , which can wrap around both batteries when their combined dimensions allow.
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 positioned around your battery, the 30" grounded 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 draws 80 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

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... - How To Keep 2 Group 31 AGM Truck Batteries Warm In Winter - Diesel PickupYes, Randy - the Zerostart 160-Watt Pad Blanket for batteries # ZE27FR is built exactly for Group 31 batteries. It’s a 72-inch wrap designed to fit those large cases and will raise the battery core about 60–70F above outside temps so you keep full cranking power in the cold. Just don’t use it on lithium or ABS-cased batteries. This setup will allow both of your batteries to stay warm if they are next to each other. If they aren't, you'll need two smaller ones like # ZE87FR. Do you already...
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... - 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... - Does Go Power Lithium RV Battery 34282738 Need HeaterHey Terry, your # RS74VRbatteries do need to be above freezing to accept a charge. They can still discharge in temperatures down to -4°F, and their internal BMS provides temperature protection. Unfortunately, we don't currently offer a 12V heating pad designed to add heating capability to these particular batteries. Our battery heating pads like # ZE87FR, operate on 120V AC rather than directly from the 12V battery bank. How cold of a climate are you in?
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... - 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... - Can Zerostart Battery Heating Pad ZE27FR Be Installed Over An Existing Thermal Blanket?Hello James, good question, glad you asked. No, you cannot place the Zerostart Battery Heating Pad # ZE27FR over an existing heating pad or thermal blanket. Doing that could cause hot spots to develop and the pad could overheat which would ruin the pad and could potentially damage your battery. You will need to remove the existing thermal blanket before installing the battery heating pad. Also, it is important that the heating pad does not overlap on itself. This could also cause overheating....
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... - Is There A Way To Keep RV House Batteries Warm During Winter Storage?You can absolutely do that, Tim. The 80-Watt # ZE87FR works great for Group 24–27 batteries that most RVs use (some even use group 31, which this heater fits as well). Just wrap it around each battery and plug into shore power or a timer so it cycles a few hours at a time when temps below freezing. Keeping those cores warm will help the converter maintain charge more efficiently. Are your batteries flooded or AGM? That can affect how long you leave it plugged in. This will not be good...
view full answer... - Which Battery Heat Blanket Is Best For Camper Depp Cycle Batteries Parked In Minnesota?Good call, Bill. Minnesota winters are no joke. For a single 12-volt Group 27 deep-cycle, the 80-Watt # ZE87FR is the perfect match. It keeps the battery warm without wasting power, and you can plug it into a timer to run overnight when temps dip below freezing. If you ever add a second battery, the 160-watt version # ZE27FR is a great option since it's big enough to wrap around/between two batteries. Do you keep your camper plugged in through the off-season?
view full answer... - Do Battery Heaters Wrap Around Battery Or Sit Under The Battery?Hey Nick! It’s a full wrap-around blanket style, not an under-tray heater. The # ZE87FR uses Thinsulate insulation and a buckle strap to hold it tight, so it surrounds the battery evenly and won’t get in the way of cables. What size battery do you have and what vehicle is it? I'll make sure this is the best style battery warmer for it.
view full answer... - Can I Wrap Battery Warmer Pad Around 2 Marine Batteries On Fishing Boat During Winter?Not quite, Susan - the 80-Watt Zerostart # ZE87FR fits one mid-sized battery at a time, so you’ll want a separate wrap for each. If you’d rather cover both in one go, the longer 160-Watt # ZE27FR 72 inches can handle side-by-side setups and is what I recommend for more efficiency and ease of use. Either way, you’ll love how the batteries will stay at full capacity with the warmers on them. Do you store the boat outside or keep it under cover during winter?
view full answer... - Availability Of 12v Battery Heater For 24 Series BatteryHey David, thanks for reaching out. We carry quite a few battery heaters, but none that operate directly off 12 volts. There is a solid alternative though, especially if your batteries sit out on the trailer tongue. Instead of trying to add an external heater, you can upgrade to a lithium battery that already has an integrated heating system built in. A great example is the Go Power Sun Cycle Advanced Lithium RV Battery # GP99QR. It has a smart DC heater inside the battery itself, so it...
