Battery Care

Due to the amount of power needed to light up the LEDs, a 3.7V Lithium-ion battery is used in the hoop. This is the same type used in many appliances such as mobile phones, laptops and cameras.

Lithium-ion batteries have a high voltage capacity and if damaged or ruptured can become extremely hot or start a fire. – Use at your own risk.

Only use ONE 3.7V Lithium-ion battery in your hoop – any more may damage the internal electronics and void the warranty.

Keep batteries out of reach of children.

Do not leave batteries charging unattended.

Use only a battery that was purchased from ULA in your hoop.
We provide high quality lithium-ion hoop batteries with inbuilt protection circuits.

Inspect batteries before each time you charge them or use your hoop. (see below for more detail.)

Do not use damaged batteries in your hoop.

Do not try to charge damaged batteries.

Do not immerse battery in water.

Disconnect the battery when hoop is not in use.

We have included reverse-polarity protection in our circuit boards to prevent damage to the battery and internal electronics in case the battery is accidentally inserted the wrong way round.

Keeping your battery in good condition will not only help maximize battery life, but also help avoid any issues that may occur by using damaged batteries.

Do not use damaged batteries in your hoop! Batteries should be inspected for damage before each time the hoop is used.
Signs of damage might be:
The plastic peeling off the sides, top or bottom of the battery.
The circuit on the bottom end of the battery becoming detached.
Any rust showing on any part of the battery.
Any water damage or discolouration of the plastic.
Dents in the battery.
Any signs of leakage/fluid coming from the battery.

If any sign of damage is observed, avoid contact with skin. The battery should not be used & should be exposed of at a local recycling centre.
If fluid is leaking from the battery, avoid contact with the skin and eyes. If any fluid gets on your skin rinse immediately with water. If fluid gets in your eye, do not rub your eye but rinse well with water and seek medical attention.

To prevent damage to batteries:
1) Keep batteries cool: Don’t store them in a hot car or in direct sunlight.
2) Keep your batteries in a battery case when not inside the hoop: Don’t just keep them in your pocket or bag where they might be damaged by coins or
keys causing a short circuit or scratching the plastic covering.
3) Do not use your hoop when the connector is in the ‘off’ position: The battery may
be damaged as it rattles around.
4) Ensure the push-button connector is secure to prevent the battery from coming
out of it’s enclosure & getting damaged.
5) Do not expose battery to heat or fire.
6) Keep battery dry & away from damp environments.
7) Do not put battery in the wrong way round (reverse polarity).
8) Do not remove the plastic wrapping of the battery.
9) Do not put the battery in any device other than your hoop and the provided charger.
10) Keep batteries away from corrosive environments such as acidity/alkali.
11) If a battery leaks any electrolyte solution, do not use & take the battery to be recycled.
12) If the battery compartment feels warm, move the push-button connector to the ‘off’
position and allow the battery to cool. Do not try to remove or touch the hot battery
as it may burn your skin.
13) Do not send damaged batteries through the mail.
14) Store any damaged batteries in a cool place in the provided battery case,
before they can be recycled.
15) Dispose of damaged batteries at a local recycling centre, not in the bin.
16) Move the silver push-button connector to the ‘off’ position when not in use
to conserve battery power: intermittent use will ensure the battery lasts as long
as possible. (‘Standby’ mode using the remote control will turn off all the LEDs,
but will still drain a small amount of battery power.)
