These figures come from our product specifications. A dash means we only publish the low-setting runtime for that product. The Merino Wool+ and Junior socks have 4 heat levels; the table shows the low, middle and high ranges.

Why the cold shortens runtime

Two things happen when it gets colder. First, lithium-ion batteries deliver less of their stored energy when they are cold, so a battery that sits in an exposed cuff at -25 °C runs out sooner than one kept warm. Second, the colder and windier it is, the more heat your hands lose, so you tend to use a higher setting, and higher settings draw more power. A wet glove also loses heat faster than a dry one.

That is why the same pair can last a full day on a calm -5 °C afternoon and only part of a day in a -30 °C wind chill on high.

8 ways to get more hours

Charge fully the night before. Recharging takes about 4 hours for most gloves, mittens and socks, about 6 hours for the Active gloves, vests and bermuda shorts.
Start on high, then go down. Warm your hands up for a few minutes, then switch to medium or low to keep them warm.
Use low when you move. Skiing, shovelling or walking produces body heat. Save high for chairlifts, ice holes and bleachers.
Turn the heat off indoors, at lunch or in the car.
Keep spare batteries warm in an inside pocket, close to your body.
Keep the gloves dry. Close the cuff over your jacket sleeve to keep snow out; dry insulation holds heat better.
Carry a second set on long days. Heat Up sells battery and charger kits for gloves and mittens, and for vests and bermudas. The vests and bermuda shorts use a standard USB power bank, so a spare is easy to find.
Size right. A glove or sock that is too tight squeezes out insulating air and feels colder, so you turn the heat up.

Do batteries wear out?

Like every lithium-ion battery, ours slowly lose capacity with age and charge cycles. If a battery no longer holds a charge the way it did, a replacement kit brings your gloves back to full runtime. Every Heat Up product comes with a 1-year warranty; contact our team at support@heatup.ca or +1 (514) 850-5585 ext. 234 if something seems wrong.

FAQ

How long does it take to charge Heat Up heated gloves?

About 4 hours for Mountain and Peak gloves, mittens and socks, with the included charger. The Active gloves, heated vests and bermuda shorts take about 6 hours.

Which Heat Up product lasts the longest on one charge?

The Merino Wool+ Heated Socks, with up to 11 hours of heat on the low setting.

Why do my heated gloves run out faster when it is very cold?

Lithium-ion batteries deliver less energy when they are cold, and you usually choose a higher setting in deep cold. Keeping spare batteries warm and starting on high before dropping to low helps.

Can I buy spare batteries?

Yes. Heat Up sells battery and charger kits for gloves and mittens, for vests and bermudas, and for kids' mittens, Active gloves and socks.
