The enclosed cells or packs have an internal protection
device (fuse) installed which will open if the cell is subjected to
a short circuit condition. This will then render the cell or pack
inoperative. DO NOT attempt to remove, replace, by-pass, or render
this internal protection device inoperative.
Any attempt to render the cell or pack unprotected is hazardous.
Under no circumstances should terminal caps and/or protection devices
be removed or cell fuses be disassembled or otherwise disabled. Never
alter an Electrochem battery pack by removing
or changing the value of the external fuse. Short circuiting an Electrochem
cell or pack from which the fuse has been removed can lead to cell
venting or explosion. Shrinkwrap insulation should not
be removed from cells. Also, under no circumstance should potting
material be cut or trimmed to alter the shape of the battery. This
could lead to exposed wires and potential electrical hazards.
Cells should be handled with care at all times an never subjected
to denting, puncturing, disassembly, exposure to fire, or exposure
to temperatures above the maximum rated temperature of the cells as
listed below:

at both maximum rated temperature and maximum rated current.
All safety and handling information provided on the WGL product
label, packaged with all shipments and printed in all catalogs
and data sheets must be observed at all times. |

To Design Engineer or Battery Installation
Personnel, reference PMX and VHT cells.
As a normal result of discharge at high temperature, the bottom
the PMX and VHT cells expand. Cells are normally supplied with
nylon bottom expansion spacer. If missing or removed, provisions
must be made in the design of the cell compartment to accommodate
this expansion. See maximum temperature chart above. Maximum

SAFETY INFORMATION
FOR ELECTROCHEM LITHIUM CELLS & BATTERIES
|
Used correctly, Electrochem lithium cells and batteries are a reliable
and safe source of power. Improper use or abuse may create a hazardous
situation, possibly resulting in the release of toxic fumes, corrosive
fluids, or an explosion of the cell/battery. Consult WGL (716-759-5428)
in advance, when designing or assembling cells into battery packs.
The following precautions must be observed when using Electrochem
lithium cells/batteries:
1. Safety glasses must be worn at all times when handling lithium
cells/batteries. In addition, when handling cells/batteries, all metallic
jewelry items must be removed to preclude a potential short circuit
condition.
2. DO NOT connect cells/batteries of different chemistries together
in a circuit. This precaution includes, but is not limited to: lithium,
alkaline, manganese, and carbon-zinc cells/batteries.
3. DO NOT connect cells/batteries of different sizes or manufacturers
together in a circuit.
4. DO NOT connect old cells/batteries and new cells/batteries together
in a circuit.
5. DO NOT short circuit the positive and negative terminals of a cell
or battery.
6. DO NOT attempt to charge, force overdischarge, disassemble, crush,
puncture or incinerate a primary lithium cell/battery. A fire, explosion,
or severe burn hazard could result.
7. DO NOT solder wires or tabs directly to the cell/battery. Solder
to the tabs or leads welded to the cell/battery by the manufacturer.
Soldering time must not exceed five (5) seconds for each tab. Solder
temperature at the tab or terminal pin must not exceed 270 C (518
F).
8. DO NOT use without appropriate protection circuitry. When connecting
cells in series and parallel, protection circuitry may include blocking
diodes, shunt diodes, fuses, or thermal cutoffs.
9. DO NOT encapsulate the cells/batteries. During discharge, their
temperature could rise above the maximum rated temperature, if insulated.
If encapsulation is required, consult with the manufacturer in advance
for
10. DO NOT connect two (2) positive or two (2) negative terminals
together when assembling “series” cell strings. Insertion
of a cell backwards will charge that cell.
11. DO NOT expose cells/batteries to high level impacts such as striking
with a hammer. Never use excessive force to free a cell/battery lodged
inside of any type of housing. Arrange work areas to prevent dropping
of cells. |
