1. Notice for Assembling Battery Pack

Shocks, high temperature, or contacts of sharp edge components should not be allowed in battery pack assembling process.

Assembling Li-ion Battery Pack

1.1.Cell connection

1) Direct soldering of wire leads or devices to the cell is strictly prohibited.
2) Lead tabs with pre-soldered wiring shall be spot welded to the cells. Direct soldering may cause damage of components, such as separator and insulator, by heat generation.


1.2.Prevention of short circuit within a li-ion battery pack

Enough insulation layers between wiring and the cells shall be used to maintain extra safety protection.
The li-ion battery pack shall be structured with no short circuit within the battery pack, which may cause generation of smoke or firing.


1.3.Prohibition of disassembly

1) Never disassemble the cells
The disassembling may generate internal short circuit in the cell, which may cause gassing, firing, explosion, or other problems.
2) Electrolyte is harmful
LIP battery should not have liquid from electrolyte flowing, but in case the electrolyte come into contact with the skin, or eyes, physicians shall flush the electrolyte immediately with fresh water and medical advice is to be sought.

1.4 Prohibition of dumping of cells into fire
Never incinerate nor dispose the cells in fire. These may cause explosion of the cells, which is very dangerous and is prohibited.

1.5 Prohibition of cells immersion into liquid such as water
The cells shall never be soaked with liquids such as water, seawater, drinks such as soft drinks, juices, coffee or others.

1.6 Battery cells replacement
The battery replacement shall be done only by either cells supplier or device supplier and never be done by the user.

1.7 Prohibition of use of damaged cells
The cells might be damaged during shipping by shock. If any abnormal features of the cells are found such as damages in a plastic envelop of the cell, deformation of the cell package, smelling of an electrolyte, an electrolyte leakage and others, the cells shall never be used any more.
The Cells with a smell of the electrolyte or a leakage shall be placed away from fire to avoid firing or explosion.


2. Period of Warranty
The period of warranty is half a year from the date of shipment. Benzo guarantees to give a replacement in case of cells with defects proven due to manufacturing process instead of the customer abuse and misuse.

3. Storing 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 year to prevent over discharge.

4. Other The 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 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.
