"DO NOT CHARGE"
Doing so may cause fire, heat generation, leakage or bursting.
WARNING!
11. To prevent damage to the safety vent inside
the battery, do not deform in any way.
1. Do not use batteries for unspecified
purposes.
12. Do not force-discharge.
Differences in voltage or terminal configuration may cause an
imperfect connection, fire, heat generation, leakage or bursting.
When a battery is force-discharged by an external power source, the
voltage drops to 0 or less (reversal voltage) and gas is generated
inside the battery. This may cause fire, heat generation, leakage or
bursting.
2. Do not charge.
When this battery is charged, gas is generated inside and raises
internal pressure, resulting in fire, heat generation, leakage or bursting.
3. Do not heat, disassem ble nor dispose of
in fire.
Doing so damages the insulation materials or the safety vent,

Manganese Dioxide Prim ary Lithium Batteries (CR series)
Sanyo m anganese dioxide prim ary lithium batteries, developed in 1976, feature high energy density.
Because they offer m any unique features not found in either convetional dry cells or silver oxide
batteries, Sanyo lithium batteries are currently used in a w ide range of equipm ent such as electronic
calculators, w atches and cam eras. In addition, they are used as a m em ory backup pow er source in
m icrocom puter-controlled devices. By offering a w ide range of lithium batteries, from coin cells to
high-pow er cylindrical type cells (spiral structure) and high-capacity cylindrical type cells (bobbin
structure), Sanyo has been able to m eet the dem ands of a large and diversified m arket.
Sanyo is acquiring International Regulation ISO9001 approval w hich is a quality guarantee. Sanyo
continues to im plem ent thorough quality control.
Principles and Structure of Prim ary Lithium Batteries
〔
〕
Applying an original manufacturing process, Sanyo uses a manganese dioxide compound as the active material for the positive electrode
(cathode). Lithium is used for the negative electrode (anode) to produce a cell with high voltage and high energy density. In addition, an
organic electrolyte is employed to which lithium salts are added.
The discharge reaction of lithium batteries is as follows:

Overall battery reaction: Mn O2＋Li→Mn O2 (Li )
The cell voltage is approximately 3V.
■ Battery Structure
High-power cylindrical type lithium batteries are capable of
producing a very high discharge current due to their spiral electrode
structure. High-capacity cylindrical type lithium batteries have a
bobbin structure which contains active material and can provide a
high capacity.

Niobium Rechargeable Lithium Batteries (NBL series)
Sanyo niobium rechargeable lithium batteries are high-capacity coin-type batteries that can be recharged
at 2.0V. These batteries are specially designed for use w ith low -voltage equipm ent. Sim ilarly w ith the ML-
series m anganese dioxide rechargeable lithium batteries, the NBL-series features a low self-discharge
rate, thus offering an expected life of 5 years at room tem perature. These batteries are optim ized for use
as m em ory backup pow er sources and can also be used in com bination w ith solar cells.
Principles and Structure of Coin Type Niobium Rechargeable Lithium Batteries
〔
〕
These batteries use niobium pentoxide as the active material for the positive electrode by employing Sanyo's original treatment process. In
turn, the active material for the negative electrode is made from lithium aluminum alloy. This allows stable cyclic performance to be
maintained at a low discharge voltage.The electrolyte is made by dissolving lithium salts in a mixed organic solvent.

Connection Term inal Specifications
〔
〕
Sanyo meets various user requirements by developing an extended line of batteries with different terminal designs (tabs, connectors and
other terminals) as well as various battery holders. Regarding standard specifications and key circuit design points, see the separately
provided "Connection Terminal Specifications for Lithium Batteries and Key Circuit Design Points."
International Transportation
〔
〕
Regulations for international transportation of lithium batteries may be largely classified into three categories.
1. Air transport
Based on DGR (Dangerous Goods Regulations) of ICAO (International Civil Aviation Organization), IATA (International Air Transport
Association) has determined transport regulations. The regulation states that lithium batteries are considered not dangerous if they
meet the following requiremints:
Each bare cell with a solid cathode must contain 1.0g (Assembled battery using more than 2 cells must contain 2.0g) or less of
lithium or lithium alloy. (Sanyo's lithium batteries are all solid cathodes.)
They may be transported in rigid packaging with short-circuit protection.
2. Marine Transport
IMO (International Marine Organization) has determined transport regulations based on IMDG (International Marine Dangerous
Goods). The judgement standard of dangerous goods is based on DGR of ICAO. When the batteries are not regarded as dangerous
goods, they should be transported in rigid packaging with short circuit protection, according to IATA standards.
3. DOT (Departm ent of Transportation)
Regulations for packaging and transportation of lithium batteries in the U.S.A. are determined by Code 49 CFR173. 185 of Federal
Register.
The judgement standard of dangerous goods corresponds to DGR of ICAO. When the batteries are not regarded as dangerous, any
transportation method is acceptable if they are transported in rigid packaging with short circuit protection.
● The following Sanyo lithium batteries contain less than 1.0g of lithium or lithium alloy (under 2.0g for assembled batteries) per single
cell.

Disposal
〔
〕
The awareness of the need to protect the earth's environm ent has increased on a global basis. As a result, regulations covering the
disposal and recycling of m ercury cells and Ni-Cd rechargeable batteries have been im plem ented in the U.S.A., Europe and Japan.
