Heated Clothing | Accessories | 2 x 7.4 batteries with USA charger
Use these Lithium Ion 7.4V spare batteries with Warmthru Mittens, WT-Gloveliners, Socks, Knee-Hugs, Waist-Hugs. They should not be used with G1-Gloveliners or Fingerheaters which use technology incompatible with these batteries. With Hotmitts, which take 2 batteries per Mitten, we recommend for each Mitten one 3.7V battery on the palmside and a 7.4V for the upper hand.Especially useful on long journeys - just replace the ones you have used up with these new charged up ones. Batteries last around 2-3.5 hours in continuous use, depending upon which heat setting. They take about 6 hours to charge following the initial charge, or overnight. The Heat Control allows you 4 heat settings - adjust using the POWER button.
