We can support UN38.3 UL REACH ROHS and other specially certfication
Never make short circuit cell. It generates very high current which causes heating of the cells and may cause electrolyte leakage, gassing or explosion that are very dangerous.
The LIP tabs may be easily short-circuited by putting them on conductive surface.
Such outer short circuit may lead to heat generation and damage of the cell.
An appropriate circuitry with PCM shall be employed to protect accidental short circuit of the battery pack.
Period of Warranty
The period of warranty is half a year from the date of shipment. TAC guarantees to give a replacement in case of cells with defects proven due to manufacturing process instead of the customer abuse and misuse.
Storage of the Batteries
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.
