6. Warning & Tips
Before using the battery, please read and follow the specifications
and precautions on the surface of the battery. Improper use may
cause heat, fire, rupture, damage, or capacity deterioration of the
battery. Shenzhen Guanyu New Energy Technology Co., Ltd. is not
responsible for any accidents caused by use, which does not meet
our specifications.
² The battery must be far away from heat source, high voltage, and
avoid to be exposed in sunshine for long time.
² Never throw the battery into water.
² Do not put the battery in a charger or equipment with wrong
terminals connected.
² Never connect the positive and negative of battery with metal.
² Avoid excessive physical shock or vibration. don't hit, fall,
stamp on the battery
² Without the permission of the manufacturer and guidance,
forbidden to remove or to assemble the battery
² Do not use the battery mixed with other different manufacturer,
type, or model batteries.
² Keep the battery against high temperature. Otherwise it will
cause battery heat, get into fire or lose some function and reduce
the life.
² When battery run out of power, please charge your battery timely
(≤15day).
² Please use the matched or suggested charger for this battery.
² If battery emit peculiar smell, heating, distortion or appear any
abnormity during working or storage, please stop using and take it
out from device.
² If the battery leaks and get into the eyes or skin, do not wipe,
instead, rinse it with clean water and see doctor immediately.

Any requirements on serials connection, please contact GUANYU for
details.
7. Battery operation instruction
7.1 Charge and discharge
7.1.1 Charging current:Do not surpass the largest charging current
that specification stipulated.
7.1.2 Charging voltage:Do not surpass the highest limited voltage
that specification stipulated.
7.1.3 Charging temperature:within temperature scope that
specification stipulated.
7.1.4 Charge with constant current, then with the constant voltage,
no reverse charge, which is dangerous
7.1.5 Special note:
Short time doesn't affect the use of the battery overcharge too,
but for a long period of time over
discharge or over charge can affect the function of the battery
failure, or the battery can't use permanent, appear serious safety
hazards, need long time floating please use the recommended
floating model specification.Battery when not in use for a long
time, because of its own self-discharge characteristics can also
cause discharge, to prevent the occurrence of a discharge, battery
should maintain a certain capacity, maintain the voltage at 50%
state of SOC.
8. Other Chemical Reaction
Because batteries utilize a chemical reaction, battery performance
will deteriorate over time even
if stored for a long period of time without being used. In
addition, if the various usage conditions
such as charge, discharge, ambient temperature, etc. are not
maintained within the specified
ranges, the life expectancy of the battery may be shortened or the
device in which the battery is
used may be damaged by electrolyte leakage. If the discharge time
is much shorter than the
normal after full charged, even battery is charged correctly, and
this may indicate it is time to
change the battery.
