CAUTION
Please charge the battery as soon as possible
if the battery level is low. Otherwise, the
lifespan of battery can be reduced. It is
better to check the battery at least once a
week.

Warning!
When using lead (WET) batteries, they may
emit inflammable gas under normal use,
must keep sparks, flames, smoking materials
and radiating, illuminating and burning
items away from batteries. When charging
lead (WET) batteries, they may emit
hydrogen gas which may cause explosive.
Must ensure the charging environment is
well ventilated and away from naked flames

CAUTION!
To be especial careful when battery is
charging, because there may be leaked acid
in the process of charging.
Battery acid is corrosive, if it accidentally
