Handling of battery
Prohibition short circuit
Never short circuit battery. It generates very high current which causes heating of the battery and may cause electrolyte leakage, gassing or explosion that is very dangerous.
The poles may be easily short-circuited by putting them on
conductive surface.Such outer short circuit may lead to heat
generation and damage of the battery.
An appropriate circuitry with PCM shall be
employed to protect accidental short circuit of the battery pack
Mechanical shock
Falling, hitting, bending, etc. may cause degradation of battery
characteristics.
Prevention of short circuit within a battery pack
Enough insulation layers between wiring and the cells shall be used
to maintain extra safety protection.
The battery pack shall be structured with no short circuit
internally, which may cause generation of smoke or firing.
Period of Warranty
The period of warranty is 12 months from the date of shipment. TAC
guarantees to give a replacement in case of battery with defects
proven due to manufacturing process instead of the customer abuse
and misuse.
The batteries should be stored at room temperature, charged to
about 30% to 50% of capacity.
We recommend that batteries be charged about once per half a year
to prevent over-discharge.
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 batteries cannot
maintain a charge for long periods of time, even when they are
charged correctly, this may indicate it is time to change the
battery.
