In a nutshell 💡
- 2 to 7 hours, depending on the selected setting. The variation depends on the heat setting, not the garment.
- For a heated jacket: 6 to 7 hours on low, 3.5 to 4.5 hours on medium, 2 to 3 hours on high.
- For heated gloves: 5 to 6 hours on low, 3 to 4 hours on medium, 1 hour 30 minutes to 2 hours 30 minutes on high.
- The right method: start at the highest setting, then lower it to maintain the temperature. This is what allows the garment to last all day.
- The battery lasts up to 500 charge cycles under optimal conditions and can be removed for washing.
Two hours. That’s the battery life of a heated garment used continuously at the maximum setting. Seven hours is the battery life of the same garment when used wisely.
The difference—from two to three times—doesn’t depend on the model, the brand, or the outside temperature. It comes down to a single factor: the heat setting, which most users instinctively leave at maximum.
Here are the actual battery life durations, product by product, what causes them to vary, and the method for covering a full day.

Actual battery life durations, by intensity
All the values below are those listed on the G-Heat product sheets. They correspond to continuous use at the specified setting.
Heated jackets, down jackets, and vests
These garments are powered by the BATV01 battery, which has a capacity of 10,000 mAh at 5 V and weighs 200 grams.
- Low setting: 6 to 7 hours of battery life
- Medium setting: 3 hours 30 minutes to 4 hours 30 minutes
- High setting: 2 to 3 hours
Heated gloves
The gloves use a more compact battery, the BATG01, rated at 2,200 mAh at 7.4 V, weighing just 65 grams. It fits inside the cuff of each glove.
- Low setting: 5 to 6 hours of runtime
- Medium setting: 3 to 4 hours
- High setting: 1 hour 30 minutes to 2 hours 30 minutes
The difference between the two product lines is simple: a glove battery must remain light enough not to hinder movement, which limits its capacity. A thin heated glove weighs 145 grams, including the battery.
What Really Affects Battery Life
Five factors, in order of importance.
- The heat setting, by far the most important: this is what explains the range from one to three times the battery life
- The outside temperature, which has an indirect effect: the colder it is, the more tempted you are to turn up the heat
- Continuous or intermittent use: turning it off during periods of physical activity makes all the difference
- The cold experienced by the battery itself: any lithium battery temporarily loses capacity in cold weather, which is why it’s important to keep it close to your body
- The battery’s age, which affects performance over the long term
Wear and tear over time
G-Heat batteries are rated for up to 500 charge cycles under optimal conditions. A cycle corresponds to a full charge, not to a single connection: recharging halfway twice counts as one cycle.
With regular winter use, this represents several seasons. Capacity loss is gradual, never sudden: an aging battery lasts shorter, but it doesn’t stop working overnight.
Why the perceived warmth doesn’t depend solely on battery life
One point that comparisons often overlook: two heated garments advertised with the same battery life do not necessarily provide the same level of comfort. The perceived warmth depends on three distinct factors.
- The number of heated zones: the more there are, the better the heat is distributed, but the higher the power consumption
- The location of these zones: heat applied to the back and lower back spreads throughout the torso, whereas heat applied to a single pocket does not
- The insulation of the garment itself: a heated down jacket traps the heat it generates, while a thin model lets it escape
That’s why the comfort of a heated down jacket set to a low setting often surpasses that of a non-insulated model set to a high setting—with three times the battery life, to boot.
How to make it last a whole day
This is where the difference lies between two people wearing the same garment.
Turn it up, then turn it down
The high setting is used to reach a comfortable temperature, not to maintain it. Once you’re comfortable, turning it down one or two notches preserves that feeling while significantly extending battery life. That’s the simple step that takes it from three hours to seven.
Turn it off during physical activity
When you’re walking, shoveling, climbing a hill, or doing physical work, your body generates its own heat. The heating becomes unnecessary during these phases, and turning it back on when you stop is more than enough. Over the course of a day that alternates between activity and rest, this simple habit doubles the battery life.
Bring a Second Battery
This is the simplest solution for long days. An extra battery for heated jackets fits in a pocket and can be swapped out in seconds. For your hands, batteries for heated gloves can be changed just as quickly. You’ll find the full selection in the batteries and chargers section.

Battery Life by Model
Not all heated clothing uses power the same way, because they don’t heat the same surface area or the same number of zones. Here’s how the major categories compare.
| Product family | Heating zones | Battery | Low / medium / high autonomy |
|---|---|---|---|
| Heated jackets | Back, neck, pockets | BATV01, 10,000 mAh | 6–7 h / 3 h 30–4 h 30 / 2–3 h |
| Heated down jackets | Back, neck, pockets | BATV01, 10,000 mAh | 6–7 h / 3 h 30–4 h 30 / 2–3 h |
| Heated vests | Back, chest | BATV01, 10,000 mAh | 6–7 h / 3 h 30–4 h 30 / 2–3 h |
| Heated gloves | Back of the hand, tops of the fingers | BATG01, 2,200 mAh | 5–6 h / 3–4 h / 1 h 30–2 h 30 |
The conclusion is clear: among heated upper-body garments, the models share the same battery and therefore the same battery life. A heated jacket, a down jacket, and a vest all last the same amount of time at the same setting.
It’s the gloves that stand out—for reasons of weight, not performance: no one wants a 200-gram battery on their wrist.
Which model to choose based on duration of use
- Short outings, less than two hours: any model will do, even at the high setting
- Half-day: heated jackets and vests work just fine at medium intensity
- Full day: low intensity, or a second battery, regardless of the model
- Extreme cold and inactivity: opt for a heated down jacket, whose insulation minimizes heat loss and allows you to stay on a low setting
Charging time and cost
Allow 6 to 7 hours for a jacket battery and 4 to 5 hours for a glove battery, using a 220 V USB AC adapter rated at 2A/5V. A night’s charge is therefore more than enough to meet your needs.
As for power consumption, the amount is negligible: G-Heat estimates about 1 cent per charge. This is a point that buyers often fail to anticipate, imagining an expense that doesn’t actually exist.
Battery Life Depending on the Garment and Activity
The right setting depends mainly on what you’re doing and what you’re wearing over it.
- Stationary outdoor activities: hunting, fishing, surveillance, guiding. Moderate continuous intensity, with a second battery for a full day
- Active work: construction sites, logistics, agriculture. Low intensity, turned off during periods of exertion and turned back on during breaks
- Winter sports: high setting on the lifts, turned off during the descent. Alternating settings is the norm here
- Commuting and two-wheeled vehicles: high setting when starting out, then low, as exposure time is limited
A heated softshell jacket illustrates this principle well: in addition to providing warmth, it acts as a windbreaker, limiting heat loss and allowing you to stay on a low setting longer. Other models include heated jackets and heated vests; the entire line is grouped under heated clothing.

Caring for the battery and the garment
Proper maintenance directly affects the battery’s lifespan—and therefore how much range you’ll have in two years.
- Always remove the battery before washing
- Charge using a 220 V USB AC adapter rated at 2A/5V (usually not included)
- Disconnect the battery when not in use to prevent self-discharge and overcharging
- Store at a moderate charge and at room temperature between seasons; never store it completely drained
- Air-dry the garment—do not use a dryer or radiator—and do not iron the heated areas
When a customer tells us that their garment isn’t lasting long enough, we always ask the same question: at what setting do you use it? Nine times out of ten, the answer is the maximum setting, from start to finish. The setting has a greater impact on battery life than any additional battery.
— Édouard Castaignet, co-founder of G-Heat
Why Choose G-Heat
G-Heat has been designing thermal regulation equipment since 2017. When it comes to battery life, our approach is to list the durations by intensity level on each product page, rather than a single, misleading figure. Advertising “up to 7 hours” without specifying that this refers to the lowest setting does no one any favors: the buyer feels misled from the very first use. Each product listing therefore specifies its three runtime durations, battery capacity, and charging time—for heated gloves as well as the rest of the line.
Conclusion
The battery life of heated clothing ranges from 2 to 7 hours, and this range isn’t vague: it represents the difference between the highest and lowest settings. The method consists of three steps: gradually increase the temperature and then lower it, turn it off during periods of physical exertion, and bring a second battery for long days. With these tips, battery life is no longer an issue.
Whatever the weather. G-Heat, in all weather conditions.
Frequently Asked Questions
How many hours does a heated garment last?
From 2 to 7 hours for a jacket, and from 1 hour 30 minutes to 6 hours for gloves, depending on the heat setting used. The low setting provides 6 to 7 hours on a jacket, while the high setting provides 2 to 3 hours.
Why does my heated garment last less time than advertised?
In the vast majority of cases, it’s because it’s being used continuously at the maximum setting. The highest figure always corresponds to the lowest heat setting. The cold temperature the battery itself is exposed to also plays a role.
How long does it take to recharge the battery?
About 6 to 7 hours for a jacket battery, 4 to 5 hours for a glove battery, using a 220 V USB AC adapter rated at 2A/5V. Overnight charging is sufficient.
How much does it cost to recharge?
About one cent, according to G-Heat specifications. The electricity consumption of heated clothing is negligible in terms of your utility bill.
How long does a heated clothing battery last?
Up to 500 charge cycles under optimal conditions, which equates to several seasons of regular winter use. Capacity loss is gradual, never sudden.
Can a second battery be used to double the runtime?
Yes, this is the simplest solution for long days. The battery is removable and can be swapped out in a matter of seconds, even on gloves.
How should the battery be stored between winters?
At a moderate charge level, unplugged, at room temperature. A battery stored completely discharged for several months may no longer charge properly.
