Enernova ETA - Power and Performance Issues

5.4 Unable to Power On
5.4.1 The ambient temperature exceeds the specified temperature
power internal protection. Li-ion battery over the specified temperatu-
re use is very likely to be dangerous, so if the ambient temperature is
very low or very high, the internal temperature protection of the produ-
ct will not respond to the power on in the shutdown state, if the power
has been turned on will stop charging and discharging. In this case,
please wait for the product temperature to recover before using.
5.4.2 If the ambient temperature is normal, the battery may have been
stored for too long to run out of battery power, please plug in the
adapter and charge for at least 1 hour before use.
5.4.3 If you take the above measures power station still can not turn on
and press any button is not responsive, the power station needs pro-
fessional maintenance.
5.5 Short Discharge Time
5.5.1 The ambient temperature has a large impact on the battery
discharge time, especially when the ambient temperature is below 0
degrees.
5.5.2 The product has a high number of cycles. The battery's capacity
will gradually decay as the number of cycles increases. Generally, when
the rated cycle life is reached, the capacity is only 80% of the rated ca-
pacity. This is a normal phenomenon and can continue to be used, but
the discharge time will be shortened accordingly.
