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 fire.

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 fluctuate 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 affect 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.

KEEP THE BATTERY PACK CHARGED 40%~80%

Lithium-ion (Li-ion) batteries don‘t suffer the memory effect 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 suffer the memory effect, 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 first. Then, fully recharge the
