How do I fix Error S1 (Battery Error) on my Coredy L900 Vacuum Cleaner?

If your Coredy L900 Vacuum Cleaner displays Error S1, open the battery compartment and check whether the battery is connected and restart the device. The battery temperature may be too high or low; wait until the battery falls to normal temperatures before usage (0 ° ~ 40 ° C/C 32 ° F to 104 ° F).
