2.4 Battery Pack Care & Maintenance
ADAPTOR: DC 9 V 1000mA AC Adaptor
The provided AC Adaptor is the only AC Adaptor you should use to recharge the
battery pack.
WARNING: Using anything other than the provided AC Adaptor may harm the battery
pack causing toxic chemicals to leak out and possibly start a re.
SMART BATTERY CHARGER
The provided AC Adaptor is a „Smart Battery Charger“ and will stop charging when
the battery pack is fully charged so it‘s OK to recharge the battery pack overnight.
However, we DO NOT recommend leaving the AC Adaptor plugged in all of the time.
BATTERY PACK: DC7.4V 2200mAh 16.28Wh
Batteries do not enjoy eternal life. All batteries have a limited lifespan. The key point
is to extend the battery pack lifespan with some simple to follow guidelines listed
below.
CHARGE THE BATTERY PACK WHILE YOU EXERCISE
The average person exercises 20 minutes a day, 3 times a week. That is what the
generator system has been designed for. At that rate the Lithium-ion (Li-ion) battery
pack charge will uctuate roughly from 40%~80% charge. It‘s still OK to exercise
everyday, which will probably recharge the battery pack to 100% which will only
slightly aect the long-term life of the Lithium-ion (Li-ion) battery pack. What the
battery pack doesn‘t like is a 0% charge which will eventually kill the battery pack.

BX90

12
KEEP THE BATTERY PACK CHARGED 40%~80%
Lithium-ion (Li-ion) batteries don‘t suer the memory eect like the old nickel cadmium
and nickel–metal hydride rechargeable batteries, so it is best to keep a charge in the
batteries at all times. It is best to not let the battery pack charge drop to zero and do not
recharge the battery pack to 100% all the time as it will shorten the battery pack‘s lifespan.
To extend the life of your battery pack, you want to keep it between 40%~80% but as
there is NO„battery percentage indicator“ only a„battery warning“ it‘s best to recharge the
battery pack when the „battery warning“ displays, and then recharge the battery pack for
a maximum of 20 minutes.
WHEN TO PARTIALLY CHARGE THE BATTERY PACK TO 80%
When you see the„battery warning“ then recharge the battery pack for a maximum of 20
minutes.
WHEN TO FULLY CHARGE THE BATTERY PACK TO 100%
Even though the Lithium-ion (Li-ion) batteries don‘t suer the memory eect, experts
recommend to calibrate the battery pack every 1~3 months (a„charge cycle“). Plug-in the
AC Adaptor and recharge the battery pack for at least 30 minutes, or overnight just like you
would recharge your Smartphone.
LONG-TERM STORAGE BATTERY PACK ISSUE
The battery pack will drain at about 5~10% a month when not in use. If storing the exercise
machine for a long period of time then make sure the battery pack is fully charged rst.
Then, fully recharge the battery pack a minimum of every 3 months. If you let the battery
pack discharge completely and leave it uncharged for a long period of time it will eventually
become incapable of holding a charge (i.e. dead battery pack). If this occurs you will need
to contact your dealer and buy and replace the battery pack.
BATTERY PACK LIFESPAN
Batteries do not enjoy eternal life. All batteries have a limited lifespan. The battery
manufacturers conservative estimate rates the Lithium-ion (Li-ion) battery pack at
300~500 cycles which is normal for most Lithium-ion (Liion) batteries just like Smartphone
or Laptop battery packs. However that DOES NOT mean the battery pack can only be
recharged 300 times, it means if you fully discharge the battery pack to 0% and recharge
the battery pack to 100%, then the battery pack will only last a minimum of 300 cycles, so it
is important NOT to do that. Experts claim that Lithium-ion (Li-ion) batteries can reach 80%
of their original capacity after 1,000 charges. After this point Lithium-ion (Li-ion) batteries
aren‘t able to hold as much electricity and will power your device for increasingly shorter
periods of time. It‘s also important to note that an aging battery pack will also decrease
in performance over time. Lithium-ion (Li-ion) battery packs do not die suddenly, but the
runtime gradually shortens as the capacity fades.

BX90
13
BATTERY NO-NO‘s
TOO LOW: A 0% charge for a long period of time. If you let the battery pack discharge
completely and leave it uncharged for a long period of time the battery pack will
eventually become incapable of holding a charge.
TOO COLD: 0°C (32°F) The Lithium-ion (Li-ion) battery pack will not charge below
freezing.
TOO HOT: 45°C (113°F) The Lithium-ion (Li-ion) battery pack will charge but you will
shorten the battery pack lifespan.
TOO WET: High humidity (or worse rain) will cause all kinds of corrosion problems not
only with the electrical equipment but also all the metal components on your exercise
machine. If you have condensation on the inside of your windows then the humidity
is too high. Interior window condensation is caused by excessive moisture in your
home. Corrosion will void your warranty, to avoid this buy and use a dehumidier
until the condensation disappears.
Battery Warning Display
When you see the „battery warning“ then recharge the battery pack for a maximum
of 20 minutes.
Battery Warning Levels
40% = STANDARD NORMAL BATTERY WARNING DISPLAY
When the LCD is fully lit and the “Battery Warning Display” appears then the battery
is at 40% capacity.
On completion of your workout, recharge the battery pack for a maximum of 20
minutes.
30% = FLASHING BATTERY WARNING DISPLAY
When the LCD is ashing the “Battery Warning Display” then the battery is at 30%
capacity and the computer is not receiving enough power, hence the LCD ashing
issue.
1) You can try to nish your workout by pedaling fast enough to fully supply the
computer with enough power. Then, on completion of your workout, recharge the
battery pack for a maximum of 20 minutes.
2) Stop your workout and recharge the battery pack for a maximum of 20 minutes.
20% = GHOST BATTERY WARNING DISPLAY
When the LCD is not lit and only a “Ghost Battery Warning Display” is barely visible
then the battery is at 20%.
Stop your workout and recharge the battery pack for a maximum of 20 minutes.

Resistance and Generator System
This exercise machine is equipped with:
Eddy Current Brake Motorized Resistance System: The Flywheel is lined with an
Aluminum Strip and a Bank of Magnets are moved by a Geared Electric Motor. The closer
the Magnets are to the moving Aluminum Strip the more „Eddy Currents“ are created
causing drag.
Mini Generator: Basically just an Electric Motor that is powered by the moving Flywheel.
Generator Controller: A sophisticated electronic device that supply‘s the Computer and/
or the Battery Pack with the correct electrical charge.
Battery Pack: The rechargeable Lithium-ion (Li-ion) battery pack is a battery in which
lithium ions move from the negative electrode to the positive electrode during discharge
and back when charging.
WARNING: The battery pack is lled with toxic chemicals and must be disposed of in a
competent manner by recycling.
