The Hotronic Power Plus S4+ Battery Pack is stronger than ever before. The switch is redesigned to prevent unintended switching. This battery is for use with ski boot heaters from Hotronic. This super powerful battery contains 4 NiMH cells that work even in the coldest weather. Fully rechargeable, the S4+ battery has 4 temperature settings ranging between 84 and 173 degrees Fahrenheit. At its most efficient, the S4+ lasts up to 21 hours. Use the first 3 temperature settings for keeping feet warm, and reserve the fourth heat blast setting for when your cold toes need an extra surge of warmth.
