LITHIUM & MICRO BATTERIES: TYPES AND FEATURES
Ever since Panasonic became the first company in the world to develop and commence
the mass production of Lithium batteries for consumer products in 1971, Panasonic has
launchedaseriesofLithiumbatteriesinmanyshapesandsizesincludingcylindricaltypes,
cointypesandpintypes.Panasonichasalsosuccessfullyintroducedcointyperechargeable

Outstanding electrolyte leakage resistance
Lithiumbatteriesemployorganicelectrolyteswithminimum
creeping so they are vastly superior in terms of leakage
resistanceunderenvironmentalchangescomparedtoother
typesofbatteriesthatemployaqueoussolutionelectrolytes.

estchallengeforbatteries.
Wide operating temperature range
Duetotheuseoforganicelectrolyteswithasolidifyingpoint
that is much lower than the aqueous solution electrolytes

Superior safety
Lithium batteries feature stable substances for the active
materials and a structural design that assures safety and,
as such, their superior safety has been verified from the
resultsofrepeatedlysubjectingthemtoanumberofdiffer-
ent safety tests. As a result, Panasonic’s Lithium batteries
havebeenapprovedunderthesafetystandard(UL1642)ofUL

SELECTING A BATTERY
Thestepsforselectingthebatteriesforthepowersuppliesof
specificequipmentaresummarizedbelow.
Preparation of required specifications (draft)
Therequiredspecifications(draft)arestudiedbycheckingthe
requirements for the batteries to be used as the power sup-
pliesofthespecificequipmentandtheirconditionsagainstthe
battery selection standards. The technical requirements for
battery selection are shown in the table below for reference
purposes.
Selection of a battery
Selectseveralcandidatebatteriesbyreferringtothecatalogs
anddatasheetsofbatterieswhicharecurrentlymanufactured
and marketed. From this short list, select the battery which
will best meet the ideal level of the requirements. In actual
practice, however, the ‘perfect’ battery is seldom found by
thismethod, instead, thebasicprocedurefollowedshouldbe
to examine the possibility of finding a compromise or partial
compromisewith the requiredspecifications (draft)and then
make a selection under the revised requirements from the
batteriescurrentlymanufacturedandmarketed.Suchapro-
cedure enables batteries to be selected more economically.
Questionsandqueriesarisingatthisstageshouldbedirected
toour batteryengineers.Sometimes, although itmay not be
shown in the catalog, the appropriate battery has become
available through recent development or improvement. As a
rule,therequiredspecificationsarefinalizedatthisstage.
Requests for developing or improving batteries
If thebattery thatmeets theessentialandspecific require-
ments cannot be found through the selection process
described above, a request for battery development or
improvementshouldbemadetoourtechnicaldepartment.A
requestlikethisshouldbecoordinatedasearlyaspossibleto
allowforasufficientstudyperiod.Whilethisperioddepends
on the nature of the request and the difficulties involved, a
leadtimeofatleast6to12monthsisusuallyrequired.
MODEL NUMBER
How to interpret the model numbers generally used for coin
type Lithium batteries
The model numbers are normally indicated using two upper-
case English letters and a figure consisting of three or more
digitsasshownintheexamplebelow.Thisnumberingsystemis
supportedbytheJapanInternationalStandardCommitteeof

PRIMARY BATTERIES
SinceLithiumprimarybatteriesarenotrechargeable,usea
reverse current blocking diode and a protective resistor in
serieswherethereisthepossibilityofchargingintheequip-
mentcircuit.
Reverse current blocking diode
Diode used
Use a low leak current diode (this current varies with tem-
perature).
Selection standard
The total allowable charging amount of a battery during its
totalusageperiodmustnotbegreaterthan3%ofthenomi-
nalcapacityofthebatteryforacointypebatteryor1%fora
cylindricalbattery.
Example
WhenaCR-2477 (1,000mAh)coin typebattery is tobeused
for5years,areversecurrentpreventingdiodewithareverse
currentof0.7μAorlessisrequired.
Use of protective resistor in series:
Selection and installation (UL Standard)
Aresistormustbeinstalledinserieswiththebatterytolimit
the charge current which will flow to the battery in case of
destruction in continuity of the reverse current preventing
diode.Themaximumallowablecurrent isspecifiedforeach
batterysizeinthetableattheright,andtheresistancevalue
oftheprotectiveresistorisdeterminedas:
1,000mAh(CR-2477)x≤ 3%(cointypebattery)=≤ 30mAh
30mAh÷usageperiod(5yearsx365daysx24hours)=0.7μA
Calculation method
R >V ÷ I
(where‘I’isthemaximumallowablechargecurrentspecified
byUL).
Conditions for UL Standard
(ContactPanasonicforfurtherdetails.)
1. Use of protective resistor in series

GENERAL SAFETY PRECAUTIONS FOR USING, HANDLING AND DESIGNINGGENERAL SAFETY PRECAUTIONS FOR USING, HANDLING AND DESIGNING
Selecting batteries
Whenselectingbatteries,giveconsiderationtosuchfactors
as the current consumption of the equipment in which the
batteriesaretobeused,theexpectedlifeofthebatteries,and
temperature intheoperatingenvironment.At lowoperating
environment temperatures, the consumption current of the
ICsdropsbutthedischargevoltageofthebatterieswillalso
decrease.Alsoitisimportanttonotethatthecapacitydete-
riorationofbatteriesinlong-termusebecomessignificantat
highoperatingenvironmenttemperatures.
Memory back-up circuit and holding voltage
Thecircuittypicallyusedformemoryback-upisshowninthe
figureontheright.Thememoryholdingvoltageisexpressed
as:VB-VF-IFxR> memoryholdingvoltageofIC.
Reverse current blocking diode
SinceLithiumprimarybatteriesarenotrechargeable,useof
areversecurrentblockingdiodeandaprotectiveresistorin
series is requiredwhere there is thepossibilityofcharging
intheequipmentcircuit.Useadiodewithalowleakcurrent
asthereversecurrentblockingdiode.Tomaintainthechar-
acteristicsofacoin typeLithiumbattery, the totalcharging
amountof thebatteryduring its totalusageperiodmustbe
keptwithin3%ofthenominalcapacityofthebattery.
For example, assuming that a CR-2477 (1,000mAh) will be
usedinamemoryback-uppowersupplyfor5years,charging
by the leak current of the reverse current blocking diode
shouldbenogreaterthan30mAh(=3%of1,000mAh),thus:
30mAh÷usageperiod(5yearsx365daysx24hours)=0.7μA.
Inotherwords,aleakcurrentblockingdiodewhosereverse
currentisnotgreaterthan0.7μAmustbeselected.
Allowable total charging amount
Notethattheleakcurrentofreversecurrentblockingdiodes
varieswithtemperature.

Thechargingcircuit iscrucial in termsofensuring that full
justice will be done to the battery characteristics. Consider
itcarefullyasthewrongchargingcircuitcancausetrouble.
Precautions regarding the charge voltage setting
Under no circumstances should constant current charg-
ing, which is used for Nickel-Cadmium batteries, be used.
Ignoringthisprecautionwillcausethebatteryvoltagetorise
toabout5V,resultinginadeteriorationofperformance.

CHARGING
Charging circuits
Thechargingcircuit iscrucial in termsofensuring that full
justice will be done to the battery characteristics. Consider
itcarefullyasthewrongchargingcircuitcancausetrouble.
Precautions regarding the charge voltage setting
Under no circumstances should constant current charging,
whichisusedforNickel-Cadmiumbatteries,beused.Ignoring
thisprecautionwillcausethebatteryvoltagetorisetoabout
5V,resultinginadeteriorationofperformance.
Charge voltage range
If a fixed-charging method is applied, please adhere to the
specifiedchargingvoltage.Guaranteedvoltageis2.8Vto3.2V
atthetemperatureof-20°Cto+60°C.
Ifthechargingvoltageexceedsthespecifications,theinter-
nalresistanceofthebatterywillriseandmaycausebattery
deterioration.Also,withachargevoltagearound4V,corro-
sionofthe terminal(case)mayoccur,causingleakage.
It is not possible for the battery capacity to recover com-
pletelywhenthechargingvoltageisbelowthespecification.

CHARGING
Charging circuits
Thechargingcircuit iscrucial in termsofensuring that full
justice will be done to the battery characteristics. Consider
itcarefullyasthewrongchargingcircuitcancausetrouble.
Precautions regarding the charge voltage setting
Under no circumstances should constant current charging,
whichisusedforNickel-Cadmiumbatteries,beused.Ignoring
thisprecautionwillcausethebatteryvoltagetorisetoabout
5V,resultinginadeteriorationofperformance.
Charge voltage range
If a fixed-charging method is applied, please adhere to the
specifiedchargingvoltage.Guaranteedvoltageis1.8Vto2.6V
atthetemperatureof-10°Cto+60°C.
If the charging voltage exceeds the specifications, the
internalresistanceofthebatterywillriseandmaycause
battery deterioration. Also, with a charge voltage around
3V,corrosionofthe terminal(case)mayoccur,causing
leakage.
It is not possible for the battery capacity to recover com-
pletelywhenthechargingvoltageisbelowthespecification.

SOLDERING LITHIUM BATTERIES
Using a soldering iron
Do not allow the soldering iron to make direct contact with
thebodiesofthebatteries.Proceedwiththesolderingquickly
within5secondswhilemaintainingthe irontip temperature
atabout350°C,anddonotallowthetemperatureofthebat-
terybodiestoexceed85°C.(HeatresistanceBRtypeis125°C)
Automatic dip-soldering bath
Solderingwithadip-solderingbathcanbeusedbycondition
butdonotallowthetemperatureofthebatterybodiesexceed
85°C. It is important tonote,dependingon the temperature
conditions inside the dipping device,that the battery body
temperature may rise after dipping due to the residual heat
retained. When a post-dipping temperature rise is observed,
reviewthetemperatureconditionsandconsideradippingtime

PREVENTING QUALITY PROBLEMS
Reduction of battery voltage and deterioration of capacity
(1) Reduction of battery voltage and deterioration of capacity
through contact with antistatic conductive materials
Incidents have been reported where terminal-mounted bat-
teries for memory back-up or coin type Lithium batteries
havecomeintocontactwithantistaticconductivematerials,
thusformingexternaldischargecircuitsandleadingtovolt-
agedropsorcapacitydeterioration.
In manufacturing plants using ICs, LSI and other semicon-
ductor components, thoroughgoing antistatic measures are
taken.Variousprotectivematerialsareusedtopreventstatic:
mostof themhavespecialcompoundsofcarbon,aluminum
foil and other metals and are therefore conductive. These
protective materials are used, for example, in the form
of packaging bags, trays, mats, sheets, films, corrugated
boardsandresincases.
A protective material may have a resistance ranging from
103to106Ω/cm,forinstance.Thismeansthatifthe and
terminalsofabatterycomeintocontactwiththismaterial,a
currentrangingfromseveralmilliamperestoseveralmicro-
amperes will flow and the battery will discharge, causing
voltagedropandcapacitydeterioration.
Whenbatteriesaretobeusednearprotectivematerials,take
every possible care to ensure that the and terminals
of the batteries or PC boards, etc. on which batteries are
mounteddonottouchtheseprotectivematerialsdirectly.

(2) Reduction of battery voltage and deterioration of capacity
through contact between batteries
Incidents have been reported where terminal-mounted bat-
teries for memory back-up or coin type Lithium batteries
have come into contact each other, thus forming discharge
circuits(shortedstate)andleadingtovoltagedropsorcapac-
itydeterioration.Observethefollowingprecautions.
1. Removethebatteriesfromthetrayoneatatime.Ifthetray
isturnedupsidedown,thebatterieswillcomeintocontact
witheachother,formingdischargecircuits.
2. Do not place batteries randomly in a parts box or other
container. Discharge circuits will be formed by multiple
batteries coming into contact numbers of the batteries,
causingthebatteriestodischargeanddrain.

Utilize the tray lid in taking out batteries Do not throw batteries randomly into a parts box by turning over trays containing batteries.
Lay a tray lid flat and place a tray containing batteries on top of it: batteries are pushed up by protrusions of the lid tray so that they can be easily picked up with fingers.
Contact of batteries with each other forms discharge circuits, thus the batteries are drained.
