Heated Gear Batteries

What batteries do heated clothing and gear use?

Most heated clothing runs on rechargeable lithium-ion battery packs made for that gear. Jackets, vests, base layers, and gloves all run on the 7.4-volt Powersheer battery, with gloves using two, one per hand, while socks and insoles use their own smaller 3.7-volt packs. Each pack plugs into the garment and sets the heat level through a controller or button. Checking which battery a piece needs before buying spares saves hassle. Keeping the right chargers on hand keeps everything ready to go.

How long do heated gear batteries last on a charge?

Run time depends on the pack size and the heat setting, usually up to 13 hours on low and about 2 to 3 hours on high for the largest jackets and vests. Bigger battery packs power larger pieces like jackets for longer stretches. Turning the heat down once you are warm stretches any battery further. For long days outside, a spare pack is cheap insurance. Charging fully the night before means you start with a full tank.

How do you charge and store heated gear batteries?

Charge them with the included charger, which fills most 7.4-volt packs in about 4 to 5 hours, and unplug once full to protect the cells. Store batteries at room temperature, away from extreme heat or cold, and avoid leaving them fully drained for long periods. Topping them off every few weeks in the off-season keeps them healthy. Never machine wash or submerge a battery, and remove it before washing the garment. Good storage habits help the pack last for many seasons.

Are heated gear batteries interchangeable between items?

Yes within the 7.4-volt line: jackets, vests, base layers, and gloves share the same Powersheer packs, though gloves use two. Socks and insoles use their own smaller 3.7-volt batteries, so a jacket pack will not fit those. Check the voltage and connector before swapping a battery between pieces.
