A guide to changing and charging the battery in the Hero EEG system.

Changing the Battery

Verify that the Hero system is turned off via the power switch on the underside of the battery compartment.  Open the battery cover and remove the battery.  Insert a charged battery with the negative pole (flat end) against the spring.

Charging the Battery

The battery has a microUSB port on it.  This can be connected directly to a computer or a 5V power supply via the included cable.  The LED light on the battery will turn blue when fully charged.

Use a power supply that conforms to the UNE-EN60950-1:2007 standard, or damage to the battery could result.  To preserve battery life, remove the battery once fully charged.

If the Hero system is being stored for a long period of time, remove the battery.  If storing the battery for more than a week or two, discharge the battery somewhat (i.e. do not store at 100% charge) or this could permanently reduce the charge capacity.

Note:  Do not charge the battery while in use.

Battery Duration and Recharge

The battery should last for more than 3 hours of continuous operation in the Hero system.  The recharge time should take less than 3 hours

If the battery duration is substantially reduced, it may be time to replace it.  Contact Bitbrain support for more information. 

Battery Type

The battery used by the Hero system is the Fenix ARB-L16-700U USB Li-ion 16340.

Working temperature range:
 0ºC to 45ºC (32ºF to 113ºF) 

Storage temperature range:
-20ºC to 60ºC (-4ºF to 140ºF) for up to 1 month
