Always fully charge your system before its first use. Systems are shipped only partially charged
and must be fully charged to achieve the proper run time. Take this time to familiarize yourself
with the meaning of the status indictor LEDs.
The Lithium-Ion battery contained in Urban will power you through many hundreds of rides
and will serve you well if you follow these simple rules:
• Never store the battery dead. Charge it up after your ride, before storing.
• Charge before you ride if you haven’t charged it within a few days. Lithium Ion
batteries lose charge slowly over time.
• Don’t leave your system on charge for days or weeks at a time. This has a very
small affect, but over a long time this can reduce runtime.
Note: For long term storage (months), you don’t need to store it full. Charge up, and run
the light down until the indicator LED is amber (75% charge). Do this every three months
or so. This also has a very small effect on battery life, but if you only use your light during
a few months of the year, it will help maintain better runtime from year to year.
Alternately, you can just charge it every 3 months and remove from the charger. Simpler,
and almost no difference in performance over time.
Charging
Charging with the USB Cable
1. Plug the included USB cable into the appropriate USB port on your computer.
2. Attach the Urban to the USB cable, inserting the plug into the system’s charging
receptacle appropriately.
3. Once the battery is attached to the USB charger, a flashing green LED will illuminate
on the back of the Urban indicating the battery is receiving a charge.
4. When the green LED stops flashing and remains a constant green, this is an
indication the battery is fully charged.
The Urban will charge from depleted to full in about 5 hours.
