〔Battery Handling Precautions for Your Own Safety〕
Lithium batteries contain combustible materials such as lithium metal and organic solvent. Improper handling can lead to
heat generation, bursting or fire. To prevent accidents, follow these precautions and refer to them when precautions
regarding lithium battery usage are described in instruction manuals for equipment you are using.
●Coin-type Primary and Rechargeable Lithium Batteries
WARNING!
1. Do not charge.
(Primary batteries, CR series).
When this battery is charged, gas is generated inside and raises
internal pressure, resulting in fire, heat generation, leakage or
bursting.
2. Do not heat, disassemble nor dispose of
in fire.
Doing so damages the insulation materials or the safety vent,
resulting in fire, heat generation, leakage or bursting.
3. Do not insert batteries with the +and --
polarities reversed.
Make sure the polarities are in the right position when inserting the
batteries into equipment. When using 3 or more batteries, the
equipment may operate even though one of the batteries is
improperly inserted. But this may cause leakage or bursting.
4. Do not short-circuit.
If the +and --- come into contact with metal objects, short circuiting
occurs resulting in heat generation or bursting. When carrying or
storing batteries, avoid direct contact with metal objects such as
bracelets or key chains by putting them in a separate bag.
5. Keep batteries out of children's reach.
If leaked liquid is ingested or a battery is swallowed, consult a
physician immediately.
6. In case of leakage or a strange smell,
keep away from fire to prevent ignition of
any leaked electrolyte.
7. Do not solder directly.
This can damage the insulation materials, resulting in fire, heat
generation, leakage or bursting.
8. Be sure to wrap each battery when
disposing or storing to avoid short sircuit.
Putting batteries together or in contact with metal objects causes
short circuiting, resulting in fire, heat generation or bursting.
9. Do not force-discharge.
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.
10 . Do not charge with high current and high
voltage.
(Rechargeable batteries, ML, NBL series).
Doing so may generate gas inside the battery, resulting in swelling,
fire, heat generation or bursting.
CAUTION!
1. If leaked liquid gets in the eyes, wash
them with clean water and consult a
physician immediately.
2. Do not use new and used batteries
together. Do not use different types of
batteries together.
Doing so may cause heat generation, leakage or bursting.
3. Do not apply strong pressure to the
batteries nor handle roughly.
Doing so may cause heat generation, leakage or bursting.
4. Do not use nor leave the batteries in
direct sunlight nor in high-temperature
areas.

■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.
In addition, the laser sealing technology ensures long-term
reliability and a battery life of up to 10 years at room temperature.
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: ●Anode reaction: Li→Li＋＋e−
●Cathode reaction: MnⅣO2＋Li＋＋e−→MnⅢO2(Li＋)
●Overall battery reaction: MnⅣO2＋Li→MnⅢO2(Li＋)
The cell voltage is approximately 3V.
Sanyo manganese dioxide primary lithium batteries, developed in 1976, feature high energy density.
Because they offer many unique features not found in either convetional dry cells or silver oxide
batteries, Sanyo lithium batteries are currently used in a wide range of equipment such as electronic
calculators, watches and cameras. In addition, they are used as a memory backup power source in
microcomputer-controlled devices. By offering a wide range of lithium batteries, from coin cells to
high-power cylindrical type cells (spiral structure) and high-capacity cylindrical type cells (bobbin
structure), Sanyo has been able to meet the demands of a large and diversified market.
Sanyo is acquiring International Regulation ISO9001 approval which is a quality guarantee. Sanyo
continues to implement thorough quality control.

●Nominal Voltage of Major Batteries
More Than 95% of Initial Capacity Even After 10 Years
A stable electrolyte, Sanyo's superior manufacturing methods
and sealing technology combine to ensure that the tendency of
lithium batteries to self-discharge is reduced to a very low level.
Even after 10 years of storage at room temperature, more than
95% capacity is retained.
Self-discharge rate per year at room temperature:
Coin type primary battery: under 1%
High-power cylindrical type primary battery:
Crimp-sealing under 1%
Laser-sealing under 0.5%
High-capacity cylindrical type primary battery: under 0.5%
−40℃to ＋85℃Operational Temperature Range
Sanyo lithium batteries have an organic electrolyte with a very
low freezing point, which guarantees reliable operation even at
extremely low temperatures.
Additionally, rigorous selection of materials and superior sealing
technology give these batteries excellent characteristics even at
high temperatures.
Coin type primary battery: −20℃〜＋70℃
High-power cylindrical type primary battery:
Crimp-sealing −40℃〜＋60℃
Laser-sealing −40℃〜＋85℃
High-capacity cylindrical type primary battery: −40℃〜＋85℃
Superior Leakage Resistance
The use of an organic solvent rather than an alkali for the
electrolyte significantly minimizes leakage. Futhermore, laser
sealing technology also minimizes the risk of electrolyte
leakage.
Greater Safety (UL approved)
Since Sanyo primary lithium batteries do not contain toxic
materials, noxious liquids or gases, they pose no major polution
problems. They are UL recognized components (File No.

Continued Backup Over One Year
The ML2430, for example, offers one year back up under
continuous discharge of 10μA at 23℃when the battery is fully
charged or when the battery capacity is the same as the
shipment.
Stable Operating Voltage of 2.5V
Sanyo rechargeable lithium batteries offer a high discharge
voltage of 2.5V, more than twice that of Ni-Cd button cells. So a
single lithium battery can be used to replace two conventional
batteries. They also offer a stable voltage over a long period,
unlike the straight-line voltage drop of capacitors.
Sanyo manganese dioxide rechargeable lithium batteries are high-capacity rechargeable coin-type
batteries. These batteries have a high voltage of 3V compared to Ni-Cd button cells (1.2V). With a low
self-discharge rate and superior charge/discharge cycle characteristics, they have an expected life of
as much as 5 years at room temperature. They are suitable for use as memory backup power sources
and can also be used in combination with solar cells.

〔Principles and Structure of Coin Type Manganese Dioxide Rechargeable Lithium Batteries〕
Manganese Dioxide Rechargeable Lithium Batteries (ML series)
Manganese dioxide, with proven performance, is used as the active material for the positive electrode through Sanyo's developed treatment.
The active material in the negative electrode, lithium aluminum alloy, offers stable cyclic performance with a high discharge voltage.
The electrolyte is made by dissolving lithium salts in a mixed organic solvent.
The charge/discharge reaction of the batteries is as follows:
●Anode reaction: (Li−AR)→
←AR＋Li＋＋e−
●Cathode reaction: MnⅣO2＋Li＋＋e−→
←MnⅢO2(Li＋)
●Overall battery reaction: MnⅣO2＋(Li−AR)→
←MnⅢO2(Li＋)＋AR
The cell voltage is approximately 3V.
■Battery Structure
■Applications
●Memory backup power sources for computer, MD and
portable cellular phones including PHS.
●Power source for portable equipment.
●Hybrid power source when combined with solar cells
●Memory backup power source for electronic equipment.
■ When the batteries are used with a contact system
●Use nickel-plated phosphor bronze or stainless steel for
terminal materials to make contact with the batteries.
●For stable contact conditions, several N of contact pressure
are recommended for the contact.

Superior Charge/Discharge Characteristics(ML2430)
Our batteries can withstand 20,000 cycles, 3,000 cycles and
500 cycles under discharge conditions of 1.0mAh (discharge
depth of 1％), 5.0mAh (discharge depth of 5％) and 20mAh
(discharge depth of 20％) respectively.
Wide Operating Temperature Range
The use of an organic electrolyte gives an extended operating
temperature range: −20℃to ＋60℃.
Charging Possible with 2.8V
Even a charging voltage as low as 2.8V ensures high charge
efficiency.
Excellent Continuous Charging Performance
Stable characteristics are maintained even when continuously
charged for long periods.
Superior Overcharging Performance
The use of an organic solvent rather than an alkali for the
electrolyte and superior sealing technology significantly reduce
the risk of leakage.
Small Self-Discharge Rate Assures Durability
The self-discharge rate of approx. 2% per year at room
temperature is much lower than that of Ni-Cd button cells. Even
after five years of storage at room temperature, you can expect
about 90% of the original capacity.

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."
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 (Department 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.
