emWave2 Battery FAQ

Jun 21, 2018

emWave2® Battery FAQ
 
  • The emWave2 device uses a high quality Lithium Ion rechargeable battery controlled by an on board battery management micro controller.
  • With one hour of use a day, we expect a lifetime of at least 5 years, providing it is recharged at least once a month, whether it has been used or not.
  • The battery is expected to have at least 85% of capacity after 500 full charge cycles.
  • Our recommendations are true for almost all products with Lithium Ion Batteries thus: We recommend charging your emWave2 for 2 hrs. right out of the box.
  • There isn't a memory effect so you can start a charging cycle whenever you choose.
  • The Battery in the emWave2 device is rechargeable but not replaceable
  • Opening the emWave2 device will violate the warranty on your device.

NOTE: We do not recommend a deep discharge.
(A deep discharge would be leaving it in a drawer for 6 months without charging it.)
  • Since all batteries self discharge after some time we recommend running a recharge cycle at least once a month.
  • If the emWave2 device is left unattended for 6 - 8 months or longer, the battery will deeply discharge on its own.
  • When plugged in, the emWave2 device power management will attempt to recover and recondition the battery.

 The procedure under these conditions are as follows :
 
  • After a deep discharge, the unit will only turn on if it's connected to a power source. Plug it in and allow it to charge for 20 minutes.
  • Unplug the device for 5 minutes and plug it back in for 20 minutes. Repeat this procedure 3 times. Note: Usually, sometime during this process, the device lights will come on and the device will begin to charge.
  • After 3 rounds, unplug it from the power source and try to turn on the emWave2. If it turns on, plug it back in and continue to charge for 2 hours.
  • After 2 hours of continuous charging, unplug the device from the power source.
  • If it does not turn on, after you unplug it from the power source, your emWave2 battery has discharged to a point where it is now unrecoverable. You may continue to use it while connected to a power source or contact your vendor for emWave2 warranty/replacement information.
