We take Battery Safety very seriously – and you should too!

Only lithium-ion batteries have enough power to light up your hoop because they have three times as much power as normal alkaline batteries. That extra energy density means they can be dangerous if used improperly.

Damaged Li-Ion batteries can start a fire, burn you, or even explode.

The most important points to remember are:

• Never use a battery that appears damaged or has its plastic peeling off. The plastic keeps the battery from short circuiting and potentially exploding. If the plastic is peeling off or the circuit at the bottom of the battery is detached or falling off, discontinue use IMMEDIATELY.
• Charge Li-Ion batteries away from people, pets, and flammable materials. Don’t leave them unattended during the charging period. Do not charge batteries on carpet, wood surfaces, car seats, or plugged directly into a wall outlet. Remove the batteries from the charger and store in the provided battery case as soon as charging is complete.
• Always store Li-Ion batteries in their case when not in use, NEVER carry them loose in a purse or your pocket. If they touch something metal like coins or your keys they can potentially explode or burn you.
• Never allow children to handle or charge Li-Ion batteries. Battery handling and charging should only be done by adults.

Li-Ion batteries are generally not sold in local stores. We only recommend using batteries from our online shop in your Moodhoop. Our batteries have special electronics built in for safety. Replace your batteries when they start to show signs of wear and tear.

Our replacement lithium-ion batteries are affordably priced, so please don't hesitate to put safety first and replace and recycle damaged batteries.

If you need to discontinue use of a damaged battery, keep it in a case or wrap it with non-metallic/non-electrically-conductive tape until it can be recycled. Call your local trash collection service to find out where you can drop off Li-Ion batteries for recycling. Sometimes damaged batteries can be recycled for free by through local stores like Lowes, Home Depot, or Best Buy. NEVER throw a damaged Li-Ion battery in the trash.

Additional safety tips:

• Never put this battery in any other device than your hoop and the provided charger.
• Inspect your batteries for signs of damage each time before use or charging.
• Never remove the outer wrapping of the battery for any reason.
• Charge the battery on non-flammable surfaces and don’t leave charger unattended.
• Once the battery is completely charged, unplug the charger from the wall and remove the battery immediately.
• If the battery compartment feels unusually hot, turn off the hoop and allow the battery to cool before discontinuing use. Do not try to remove or touch a hot battery as it can burn your skin.
• If a battery leaks any electrolyte solution, discontinue use immediately. If the solution gets on your hands, wash thoroughly with water to dilute.
• If the battery has been exposed to water or shows rust or discoloration around the positive or negative end of the battery, discontinue use immediately.
• Do not store batteries in a hot car or in direct sunlight.
• Do not store a battery inside your hoop for extended periods.
• Keep batteries away from heat and fire.
• Do not operate the charger in a wet environment.
• Keep batteries away from acidic, alkali, or other corrosive environments.
• Pay attention to the polarity (i.e. which end is positive and which end is negative) when inserting the battery.
• Never ship damaged batteries through the mail.

Get the most out of your batteries.

Battery care is a regular part of hoop maintenance. If batteries are not cared for as described it’s possible for them to expire after only a few months or even after a few uses. With proper care they can remain usable for more than a year. Regardless of care, all rechargeable li-ion batteries will lose capacity over time and eventually need to be replaced (just like in your phone or laptop).

Keep in mind the following points to maximize the life of your battery:

• Only use the provided charger with your battery.
• Do not allow your battery to sit in a completely discharged state for extended periods of time.
• Keep your batteries charged in between hooping sessions for convenience so you can pick up and play whenever you want, but do not store in the charger. Remove the battery and store in a battery case once charging is complete.
• Don’t store the battery in a hot car. Heat will rapidly diminish the life of your battery.
• Avoid throwing or dropping batteries to keep the plastic intact.
• Avoid hooping with the battery in the hoop in the off position as this can sometimes cause the plastic wrapper to peel.
• If your battery has reached its end of life, please see the above steps listed in Battery Safety for important information on how to dispose of your batteries.

Environmental factors from regular usage and manufacturing defects are out of our control and we cannot be held liable for any issues resulting from battery use or misuse, charging, handling, or storage. Use these batteries at your own risk.

Battery Care in Cold Weather

Lithium-ion batteries are sensitive to temperature, and cold conditions can temporarily affect their performance. If you use your LED hoop or other MoodHoops props outdoors during winter, keep the following tips in mind:

• Reduced battery performance: Cold temperatures can temporarily reduce a battery's available power and runtime. Your prop may appear to drain faster than usual or turn off sooner, even when the battery was fully charged before use. Much of this temporary loss of performance may recover after the battery returns to room temperature.

• Keep batteries warm before use: Store your props and spare batteries indoors at a comfortable room temperature until you're ready to perform. Avoid leaving them outdoors or in a cold vehicle for extended periods.

• Never charge a freezing or near-freezing battery: Do not charge lithium-ion batteries at or below 32°F (0°C). Charging at these temperatures can permanently damage the battery and create safety risks. For the safest charging conditions, allow batteries and battery-powered props to return fully to room temperature before connecting them to a charger.

• Protect against moisture and condensation: Moving a cold prop into a warm environment can cause condensation to form. Allow your prop to warm up and ensure that its battery compartment, charging port, and other electrical connections are completely dry before charging or opening the electronics.

• Be mindful of cold-weather impacts: Plastic tubing can become more vulnerable to damage in cold conditions, particularly during drops or impacts against hard surfaces. HDPE tubing is generally better suited to colder environments than more rigid polypro tubing, although neither is impact-proof.

For outdoor winter performances, we recommend testing your prop under the expected conditions before the event and keeping fully charged spare batteries available when your model supports removable batteries.
