How your 7V heated gear works
Plug in. Turn on. Everything you need to power, charge, and care for your 7V Gerbing gear — across all three battery generations.
How to power your gear
Connect, turn on, choose heat
Connect
Plug a charged 7.4V battery into the power cord inside the power pocket. Push in firmly.
Turn on
Press and hold the control button 3–5 seconds until the LED lights turn on.
Choose heat
Press the button 1–3 more times to set high / medium / low. LEDs show the setting.
Turn off
Hold the button 3–5 seconds until lights go off. Disconnect the battery when not in use.
How to charge
Charging your battery
We recommend charging overnight for the first charge. Charge times vary by battery model — see the battery cards below.
Plug into battery
Connect the charging plug into the charging port on the battery.
Plug into wall
Plug the wall charger into a standard wall outlet.
Charge to green
Charger light is red while charging and turns green when complete (about 3–6 hrs).
Reading your LED lights
Battery life & heat at a glance
On the 3,400mAh & 2,600mAh batteries, the number of illuminated lights shows remaining charge. To check it, disconnect the battery and hold the power button (3,400mAh), or plug it into the garment and view the lights (2,600mAh): all lights = full (76–100%), most = 51–75%, about half = 26–50%, one = low.
For heat setting, the lights or button color show the level. The 2,200mAh and 2,600mAh use button color (red/white/blue or red/yellow/green); the 3,400mAh uses the number of red lights.
Usage & storage
Get the most from your battery
Usage: always use Gerbing battery packs and chargers with Gerbing heated products — other batteries can cause overheating and damage. A Low/Medium power setting is sufficient around 50–64°F; in colder temperatures, Medium/High works well. Don't use the HIGH setting for more than 5 minutes at a time.
Storage: keep the battery at least 25% charged when not in use, and top it up periodically through the year. Always disconnect the battery from the garment when stored — a connected battery slowly drains even when the gear is off. Stored between -4°F and 120°F and cared for properly, batteries last 500+ charge cycles.
Know your battery
Which 7V battery do you have?
Gerbing has used three 7.4V battery generations. Find yours below to read its LED lights correctly and know its charge time.
Check the indicator lights or button on your battery against the cards above to identify your model.
FAQ & troubleshooting
What kind of battery powers 7V Gerbing® garments and gloves?
All garments and gloves are powered by a 7.4V rechargeable battery (Lithium-Ion or Lithium-Polymer depending on the kit). Charge your battery per the instructions provided in the package.
How long does it take to charge a 7-Volt battery?
Charge to 100% before use. Charge time depends on the battery: about 3–5 hours for the 3,400mAh, 4–6 hours for the 2,600mAh, and 3.5–5 hours for the 2,200mAh. We recommend charging overnight for the first charge. The charger light is red while charging and turns green when complete. Maintain at least 25% power when the battery is not in use to prolong its life.
How do I turn on my 7-Volt battery?
1. Power on by pressing and holding the power button.
2. To change temperature, press and hold the power button until the LED reflects your desired setting. The power-level setting can only be indicated when connected to a garment.
3. Check remaining battery life by disconnecting the battery from the product, then press and hold the power button — the LED shows the remaining charge (full lights = full power).
How do I plug in my 7-Volt battery?
1. Locate the power pocket — it's on the wearer's left outer pocket.
2. Open the pocket and locate the power plug.
3. Turn on the battery by holding the power button until it lights up.
4. Insert the plug into the battery port and push down to secure it in the plug holder.
5. Press the power button to select your setting.
6. Place the battery into the pocket and close it.
What do the LED light colors mean on my battery?
It depends on your battery. The 3,400mAh uses red lights (number of lights = charge level and heat setting). The 2,600mAh uses blue lights for charge and a button color for heat (red = high, yellow = medium, green = low; clear = off). The 2,200mAh uses a button color for heat (red = high, white = medium, blue = low). See the battery cards above to identify yours.
How should I store my battery in the off-season?
Keep it at least 25% charged and top it up periodically through the year — letting it fully drain in storage shortens its life. Disconnect the battery from the garment when not in use, since a connected battery drains slowly even with the gear off. Store between -4°F and 120°F. Properly cared for, the battery lasts 500+ charge cycles.
