Why Proper Care Matters
A heated jacket is a more complex garment than a standard coat — it contains embedded heating elements, wiring, and a battery connection port. With the right care, a quality heated jacket will last for many seasons. With the wrong care, you risk damaging the heating elements, degrading the battery, or ruining the outer fabric. The good news: caring for a heated jacket isn't complicated once you know the rules.
Before You Wash: The Non-Negotiables
Before washing your heated jacket, always:
-
Remove the battery pack. Never wash a heated jacket with the battery inside. Water and lithium-ion batteries are a dangerous combination. Disconnect and remove the battery pack completely before washing.
-
Close all zippers and velcro. This protects the zipper teeth and prevents velcro from snagging the fabric during the wash cycle.
-
Check the care label. Every heated jacket has specific care instructions. Always read and follow the manufacturer's label — the guidance below is general, but your specific jacket may have additional requirements.
How to Machine Wash a Heated Jacket
Most heated jackets are machine washable, but they require a gentle approach:
- Remove the battery pack and all accessories from pockets.
- Close all zippers and fasten any velcro closures.
- Turn the jacket inside out to protect the outer fabric and heating element connections.
- Place the jacket in a mesh laundry bag for extra protection.
- Use a cold water, gentle cycle setting. Hot water can damage heating elements and degrade the outer fabric's DWR coating.
- Use a mild, liquid detergent. Avoid powder detergents, fabric softeners, bleach, or dry cleaning solvents — these can damage the heating elements and fabric.
- Run an extra rinse cycle to ensure all detergent is fully removed.
How to Hand Wash a Heated Jacket
If you prefer to hand wash (or your care label recommends it):
- Remove the battery pack and close all zippers.
- Fill a basin or bathtub with cold water and a small amount of mild liquid detergent.
- Submerge the jacket and gently agitate the water. Do not wring, twist, or scrub aggressively.
- Drain the soapy water and refill with clean cold water. Rinse thoroughly until no detergent remains.
- Gently press excess water out of the jacket — do not wring.
How to Dry a Heated Jacket
Drying is where most people make mistakes. Follow these guidelines:
-
Tumble dry on low heat if the care label permits. Low heat is safe for most heated jackets and helps restore the loft of any insulation fill.
-
Never use high heat. High dryer temperatures can melt the heating element wiring or damage the battery connection port.
-
Air drying is always safe. Lay the jacket flat or hang it on a wide hanger in a well-ventilated area. Avoid direct sunlight, which can fade the fabric and degrade the outer coating over time.
-
Do not iron a heated jacket. The heat from an iron can damage the heating elements embedded in the fabric.
- Make sure the jacket is completely dry before reattaching the battery pack or storing it.
Battery Care and Storage
The battery pack is the heart of your heated jacket. Treat it well and it will last for years:
-
Charge fully before first use and before each season.
-
Don't let the battery fully discharge repeatedly — this degrades lithium-ion cells over time. Recharge when the battery indicator shows one bar remaining.
-
Store at room temperature. Extreme cold or heat degrades battery capacity. Don't leave the battery pack in a freezing car or a hot garage.
-
Store at partial charge for long-term storage. If you're putting the jacket away for the off-season, charge the battery to around 50–60% before storing. A fully charged or fully depleted battery stored for months degrades faster.
-
Keep the charging port clean and dry. Use a dry cloth to wipe the port if it gets dirty or wet.
Seasonal Storage Tips
When the cold season ends and you're putting your heated jacket away:
- Wash the jacket before storing — oils, sweat, and dirt left in the fabric can degrade materials over time.
- Store the jacket in a cool, dry place away from direct sunlight.
- Don't compress the jacket tightly for long periods — this can damage insulation fill and heating element placement.
- Store the battery pack separately at partial charge in a cool, dry location.
- Check the jacket and battery at the start of each season before use.
Troubleshooting Common Issues
Heating element not working after washing: Make sure the jacket is completely dry before testing. Moisture in the wiring can temporarily prevent the heating elements from functioning. Allow 24–48 hours of air drying and test again.
Battery not holding charge: Lithium-ion batteries degrade over time. If your battery no longer holds a useful charge after 2–3 years of regular use, it may be time to replace the battery pack.
DWR coating no longer beading water: The DWR (durable water repellent) coating on your jacket's outer fabric wears off over time. You can restore it with a DWR spray or wash-in treatment available at outdoor gear retailers. Follow the product instructions carefully.
The Bottom Line
Caring for a heated jacket is straightforward: remove the battery before washing, use cold water and gentle detergent, dry on low heat or air dry, and store the battery properly in the off-season. Follow these steps and your Kelvin Coats heated jacket will deliver reliable warmth for many winters to come.
