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.
