Volt Heat 7V VB730Y Rechargeable Battery

The Volt VB730Y 3350mAh is a replacement battery for your Volt Heat 7 volt heated products. This battery may not look like earlier model Volt 7V batteries, but the 730Y is compatible with all Volt 7V jackets, vests, and gloves, with the exception of Polar X, Avalanche X, and Impulse X. 

The Volt Heat VB730Y 7 Volt Battery can either be purchased for an extra battery or as a replacement for Volt batteries BL704c29, BL704c22, BL704c25, BP074302, BP074222, BP074261, BP074262, VB722, VB726, and VB729.

The difference between the VB730Y Battery and other Volt 7 colt batteries is the Milliamp Hour rating or mAh. mAh refers to the capacity of the battery and can be thought of as the size of the fuel tank. The higher the mAh rating, the longer the battery will heat your Volt product per charge.

Volt Resistance heated clothing was developed to provide a solution to people who suffer from the cold in situations where the body is not able to provide the warmth needed. Whether you suffer because of a medical condition or if you just hate being cold, we are proud to offer a complete line of heated products with our patented Zero Layer heating technology that allows you to manage your thermal comfort regardless of the temperature.

Products that Outperform: At Volt Heat we use only the highest quality UL tested electronics and top rated battery cells. We incorporate our patented Zero Layer heating system into fashionable products using technical fabrics and advanced insulating materials. Our products have been tested against others in the market place and have come out on top. Most recently our heated vest and heated gloves were selected as "The Best" by a non-profit organization created to research, test, and rate consumer products objectively.

Volt Heat Guarantee: We stand behind what we make. Any defects or failures in workmanship will be covered for life. We want your Volt Heat product to be able to help keep you warm season after season. If for any reason you are not satisfied with your purchase of your Volt Heat product send it back within 30 days for a full product refund.

Outdoor Passion: Powder skiing in untracked back country, bow-hunting from a treestand or making sure you attend every one of your child's sporting event. People with that kind of passion won't let inclement weather interfere with their personal enjoyment. We are just as passionate to help provide them with the most warm and comfortable experience regardless of the weather.

Battery Heating Technology: Volt Resistance battery heated clothing uses safe and durable heating technology powered by rechargeable lithium-ion battery packs. Our garments are designed to help keep your body core warm and to help you maintain an optimal temperature, through thermal comfort. Each product includes heating elements made of tiny conductive fibers engineered to provide optimal heat. Combine this with insulating materials designed to both retain and reflect heat toward the body and you get the best thermal management system available.

Active Heating Technology: Our heated gear is designed to keep out the cold and uses insulating materials to work with the body's natural ability to generate heat, but the drastic difference is that our heating technology provides "active" heat for those situations where the body is not able to provide warmth. This is especially important for people with poor circulation, or who suffer from conditions like Raynaud's Disease.

Heat Transfer System: Our "active" heating system uses both conduction and radiation heat transfer methods to help keep you warm. Conduction is direct heat flow through matter and resulting from physical contact. Our products have a heating system designed specifically for conduction to create warmth by stimulating blood flow. Our system also generates infrared rays that emits upward with help of a thermal reflective barrier. When these rays strike the surface of another object like the fabric and the body, the rays are absorbed and then heat is produced. This heat spreads throughout the mass by conduction.

Zero Layer Technology: Our patent pending Zero Layer design uses a special tape sealing process, bonding the heating system directly to the shell fabric. This allows for better heat transfer and eliminates bulky extra layers.

How Volt Heat Rechargeable Batteries Work:

  • Remove battery(ies) and charger from packaging.
  • Plug the charger into a properly rated AC electrical outlet.
  • Connect the batteries to the output plugs from the charger to commence charging.
  • The LED light(s) on the charger will show "red" when charging.
  • Batteries will be fully charged when the LED indicator on the charger turns green. Fully discharged batteries will take 5 hours to charge completely.
  • Disconnect batteries from charger output plugs.
  • Locate the output plug from the pocket on the product and connect to battery.
  • Press the "power" button to activate and select desired power level.
  • When finished, press the power button to turn off, unplug the batteries and recharge for next use.

Great replacement for HD heat gear!
January 19, 2023
When my wife asked me to get a new battery for her HD heat gear. Of course HD had discontinued the batteries and couldn't tell me where to get a replacement. So after a quick Google search I found them here at the Warming Store. I will tell you the batteries from HD have a flush mount surface plug-in. The plug-in for this battery is recessed but will still work with HD heat gear. It lasts 4 hours on set on high. The Warming Store is now my go-to place!
  • HD replacement battery!
  • Long lasting!
  • Fits HD heat gear and charger!

Spare battery lasts longer
November 16, 2022
Overall a decent rechargeable battery. Lasts longer than original. Although not enough for the additional cost. Even turned down to 50% doesn’t appear to improve time of service. But does allow time to recharge other battery and have continued use.
  • Easy to attach.
  • Other vests use universal phone chargers as batteries. This vest doesn?t. Eventually when batteries fail to charge, best will be just ?another vest? in the closet.
