4. Why does the LED on the lithium pack flash even though the lithium pack has been switched off?

When the middle LED flashes (every 2-3 sec.) this signalizes that your lithium pack is in stand-by mode. The switch off time depends on the lithium pack generation. Please read the manual carefully or consider the graphics underneath. The lithium pack rcB has an automatic shutdown function that switches the lithium pack to POWER-OFF mode. The lithium pack rcB switches off automatically (POWER-OFF) when the lithium pack rcB is switched to a heating level (1, 2 or 3) but no heat sock/vest/bandage/glove is attached or when the battery is in stand-by mode (middle LED flashes) and no heat sock/vest/bandage/glove is attached.

5. What can I do if the lithium pack does not change from the Stand-By Mode to the Power-Off mode and keeps flashing?

  • Make sure that no heat sock/vest/bandage/gloves or charger is connected to the lithium pack.

  • Make sure that the Lenz heat app is closed completely at your smartphone and that there is no existing connection to the lithium packs via Bluetooth.

  • Make sure that the lithium packs have no active connection to or with Bluetooth compatible devices (BLE devices) at the immediate area.

  • Press the power button on the lithium pack and switch the lithium packs to Stand-By Mode.

7. How do I know that my lithium pack is compatible with the Lenz heat app?

Bluetooth-enabled lithium packs are marked with the "Bluetooth" icon on the front as well as "Bluetooth Smart" on the back.

8. What should I do for long term storage?

Please discharge the lithium packs and half charge (see user manual) – DO NOT FULL CHARGE! Turn off the lithium packs and store disconnected from the charger.

We recommend the lithium packs be discharge every 6 months and again half charged. Proper storage of lithium packs will increase their  performance and lifetime.

9. How can I check if my lithium packs are half charged?

Fully discharged the lithium pack and charge them approximately 1-2 hours. With the rcB 1200/rcB 1800 lithium pack, the charge state can be checked at any time via the Lenz heat app.

 

10. For which purpose the rubber rings are attached to the packaging?

There are 3 x 2 pcs. of elastic rubber rings enclosed to every set of rcB 1200 / rcB 1800 lithium packs.

These coloured rubber rings will facilitate matching the battery pack, for example, should more friends / family members have the same lithium packs in use. In that case you can mark your battery packs with one color (f.e. yellow) and the other person with a different color (f.e. red).

The rubber rings can be fixed between the battery cell units.
Thus, there is no likelihood of confusion of the lithium packs, if the lithium packs had been paired already to the Lenz heat app.

11. Can you take Lenz lithium packs onto an airplane?

Please contact your airline to discuss the matter. Most airlines apply a limit of 100 Wh per person. The Lenz lithium pack rcB 1200 Accupack has 8.88 Wh, the Lenz lithium pack rcB 1800 Accupack has 13.32 Wh.

 

12. Can the LEDs of the lithium packs be turned off while they heat?

Yes, the LEDs can be turned off using the function “ON/OFF” in the Lenz heat app while the heating function remains active.

13. The capacity of my lithium packs is lower than initially, what can I do?

Please charge and discharge the lithium packs completely three times. According to experience, this should improve capacity. If this is not the case, please contact our service centre.

14. I have connected my lithium packs with the charger, but they do not charge, what can I do?

Please press the function key on the lithium pack to start the charging process. The charging process / status can be tracked based on the increasing number of permanently lit LEDs on the lithium pack.
Details regarding the charging process are also set out in the manual.

15. How big and heavy are the lithium packs?

The lithium packs have the following dimensions per unit:
lithium pack rcB 1200 85 grams 8.5 cm x 5.5 cm x 1 cm
lithium pack rcB 1800 95 grams 8.5 cm x 5.5 cm x 1.5 cm

1. How does the heat socks work?

The heat socks are performance socks with a proportion of merino wool. The heating element is integrated/sewn in these socks. The lithium pack can be attached to the legband via press buttons. The legband can be turned over the lithium pack.
Heat can be regulated via 3 settings on the lithium pack or continuously via smartphone (lithium pack rcB 1200/1800).

2. Where do the heated socks dispurse heat?

The heating element of the 1.0 and 3.0 socks are located at the ball of the foot. After only a short time heat is dispursed to the entire sole of the foot.
At the heat socks 5.0 toe cap® the heating element incorporates the entire toe area, heating the toes from the top and the bottom. This results in an optimum heat chamber for a maximum feeling of cosy well-being. We recommend wearing the socks directly on the skin.

The heat socks only heat in the toe area because it is the extremities such as the toes that always turn cold first in the cold. Once the toes are cold, coldness slowly spreads throughout the entire foot and the blood vessels at the surface of the body constrict. If the toes remain warm thanks to the heat socks, optimal circulation in the entire foot and leg is ensured.  

 

3. What is the difference between the heat socks 1.0, heat socks 1.0 slim fit, heat socks 3.0, heat sock 4.0 toe cap® and heat socks 5.0 toe cap®?


The heat socks 5.0 toe cap® have a shin protector and a heating element which contains the complete toe area. This means that the toes are heated from both the top and the bottom, and an optimum heat chamber is created. These heat socks 5.0 toe cap® are suitable for all outdoor activities, and are particularly suitable for wearing in tight-fitting and fitted (ski) shoes. The natural material mix of merino wooland silk supports the excellent heat effect of the sock.

The heat socks 5.0 toe cap® slim fit have a shin protector and a heating element which contains the complete toe area. This means that the toes are heated from both the top and the bottom, and an optimum heat chamber is created. They have a deliberately more narrow fit in the area of the forefoot, and are specifically suitable for narrow feet. These heat socks 5.0 toe cap® are suitable for all outdoor activities, and are particularly suitable for wearing in tight-fitting and fitted (ski) shoes. The natural material mix of merino wooland silk supports the excellent heat effect of the sock.

The heat socks 4.0 toe cap® have a heating element which contains the complete toe area. This means that the toes are heated from both the top and the bottom, and an optimum heat chamber is created. Available in black, they are the perfect companion for work and leisure. Available in green, they are the perfect socks for hunting and forestry purposes.

The heat socks 1.0 have a shin protector and the heating element is located directly below the area of the toe and ball of the foot. Ideal for all outdoor activities.

The heat socks 1.0 slim fit have a deliberately more narrow fit in the area of the forefoot and also have a shin protector. The heat element is located directly beneath the area of the toe and the ball of the foot. Ideal for all outdoor activities.

The heat socks 3.0 unisex have a reduced volume and, available in black, they are the perfect companion for work and leisure. Available in green, they are the perfect socks for hunting and forestry purposes. The heat element is located directly beneath the area of the toe and the ball of the foot.

4. How does the heat vest/heat bandage work?

The lithium batteries of the heat vest can be fastened with press buttons at the inside of the vest on the left and right side. Heat is dispursed at the kidney and back area. Heat can be regulated via 3 settings on the lithium battery or continuously via smartphone (lithium pack rcB 1200/1800).
