Capacity indication
Without load, press & hold the black button to check capacity level:
1. LED: Remaining Capacity <=40%
2. LEDs: Remaining Capacity <=60%
3. LEDs: Remaining Capacity <=80%
4. LEDs: Remaining Capacity <=100%
(2) Output level control
With load, press & hold the black button for 2 seconds to power on:
1. The 1 LED light in blue color means the output power is about 100% output power
2. Press the black button again, the 2 LED light in blue color means the output power is about 75% of full output power
3. Press the black button again, the 3 LED light in blue color means the output power is about 50% of full output power
4. Press the black button again, the LED 4 light in blue color means the output power is about 25% of full output power
5. Press & hold the black button for 2 seconds, the LED is off, and the power output also is off.
(3) Application:

1. High energy density
Potential for yet higher capacities.
2. Relatively low self-discharge
Self-discharge is less than half that of nickel-based batteries.
3. Low Maintenance
No periodic discharge is needed; There is no memory.
· 4. Very low profile
Batteries resembling the profile of a credit card are feasible.
· 5. Flexible form factor
Manufacturers are not bound by standard cell formats. With high volume, any reasonable size can be produced economically.
6. · Lightweight
Gelled electrolytes enable simplified packaging by eliminating the metal shell.
· 7. Improved safety
More resistant to overcharge; Less chance for electrolyte leakage.
