If a battery fails to wake up, verify that it has not been fully discharged below its safety
cutoff. If necessary, apply a
low-current charge (such as a trickle charge from solar or
a DC power source) for several minutes before attempting to power it on again. If the
battery remains unresponsive, refer to the troubleshooting section or consult the
Renogy support team.
