Both of cathode and anode welding the tags
In order to avoid short circle , the battery put specially sponge pallet.
six pcs in one little box , and 10 box in one carton
15 days after the customer confirmed the Pi and arrange the payment.
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 three months to prevent over-discharge
The period of warranty is 18 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.
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.
