Safety Instructions |
This battery
contains lithium, organic solvents, and other
combustible materials. For this reason,
improper handling of the battery could lead to
distortion, leakage*, overheating, explosion, or
fire, causing bodily injury or equipment trouble.
Please observe the following instructions to
prevent accidents.
(* Leakage is defined as the unintentional
escape of a liquid from a battery.) |
— Handling |
| |
Never swallow.
Always keep the battery out of the reach of
infants and young children to prevent it from
being swallowed. If swallowed, consult a
physician immediately.
Never charge.
The battery is not designed to be charged by any
other electrical source. Charging could
generate gas and internal short-circuiting,
leading to distortion, leakage, overheating,
explosion, or fire.
Never heat.
Heating the battery to more than 100 deg. C
could increase the internal pressure, causing
distortion, leakage, overheating, explosion, or
fire.
Never expose to open flames.
Exposing to flames could cause the lithium metal
to melt, causing the battery to catch on fire
and explode.
Never disassemble the battery.
Do not disassemble the battery, because the
separator or gasket could be damaged, leading to
distortion, leakage, overheating, explosion, or
fire.
Never reverse the positive and negative
terminals when mounting.
Improper mounting of the battery could lead to
short-circuiting, charging or forced-discharging.
This could cause distortion, leakage,
overheating, explosion, or fire.
Never short-circuit the battery.
Do not allow the positive and negative terminals
to short-circuit. Never carry or store the
battery with metal objects such as a necklace or
a hairpin. Otherwise, this could lead to
distortion, leakage, overheating, explosion, or
fire.
Never weld the terminals or weld a wire to
the body of the battery directly.
The heat of welding or soldering could cause the
lithium to melt, or cause damage to the
insulating material in the battery. This could
cause distortion, leakage, overheating,
explosion, or fire. When soldering the battery
directly to equipment, solder only the tabs or
leads. Even then, the temperature of the
soldering iron must be below 350 deg. C and the
soldering time less than 5 seconds. Do not use
a soldering bath, because the circuit board with
battery attached could stop moving or the
battery could drop into the bath. Moreover do
not use excessive solder, because the solder
could flow to unwanted portions of the board,
leading to a short-circuit or charging of the
battery.
Never use different batteries together.
Using different batteries together, i.e.
different type or used and new or different
manufacturer could cause distortion, leakage,
overheating, explosion, or fire because of the
differences in battery property. If using two
or more batteries connected in series or in
parallel even same batteries, please consult
with Maxell before using.
Never allow liquid leaking from the battery
to get in your eyes or mouth.
Because this liquid could cause serious damage,
if it does come in contact with your eyes, flush
them immediately with plenty of water and
consult a physician. Likewise, If the liquid
gets in your mouth, rinse immediately with
plenty of water and consult a physician.
Keep a leaking battery away from fire.
If leakage is suspected or you detect a strong
odor, keep the battery away from fire, because
the leaked liquid could catch on fire.
Never touch the battery electrodes.
Do not allow the battery electrodes to come in
contact with your skin or fingers. Otherwise,
the moisture from your skin could cause a
discharge of the battery, which could produce
certain chemical substances causing you to
receive a chemical burns.

— Circuit Design for Back-up Use |
| |
This is a primary
battery and cannot be charged. If used in
memory or RTC back-up applications, be sure to
use diodes to prevent charging from the main
power source or other batteries, and protective
resistance to regulate the current as shown in
the figure below. Note that the points
described below should be taken into careful
consideration when selecting diodes and
protective resistance.
Supplied voltage to load
Because a diode and a resistance generate the
voltage drop on operating, please take into
consideration these voltage drops for supplied
voltage to load.
Using diodes to prevent charging
Please choose diodes with leak current as small
as possible. Please keep the charged capacity
due to leak current to within 1% of nominal
capacity.
|
| |
Using and setting protective resistance
Protective resistance is used to prevent the
battery from being charged by large surges of
current during diode failure. Please set the
resistance so that the charge current does not
exceed the maximum allowable charge current.
For example, say a CR2032 battery is used in
sample circuit (A) in combination with a main
power source 5 volt. Since the permitted charge
current is 10mA and this battery's voltage is
3V, let resistance be R> = (5V-3V)/10mA=0.2k ohm,
meaning that at least 0.2k ohm is required. |

— Disposal |
| |
The
battery may be regulated by national or local
regulation. Please follow the instructions of
proper regulation. As electric capacity is left
in a discarded battery and it comes into contact
with other metals, it could lead to distortion,
leakage, overheating, or explosion, so make sure
to cover the (+) and (-) terminals with friction
tape or some other insulator before disposal. |
 |
— Handling/Storage |
| |
Never expose
the battery to ultrasonic sound.
Exposing the battery to ultrasonic sound may
cause short-circuiting because the inside
material is broken into pieces, leading to
distortion, leakage, overheating, explosion, or
fire.
Never subject the battery to severe shock.
Dropping, throwing or stomping on the battery
may cause distortion, leakage, overheating,
explosion, or fire.
Never short-circuit the battery while
installing into equipment.
Please be careful when installing the battery
not to short-circuit it with metal portions of
the equipment.
Use the correct battery suitable for the
equipment.
The battery may not be suitable for the specific
equipment due to the using conditions or type of
equipment. Please select the suitable battery
according to the handling instructions of the
equipment.
Never use or leave the battery in a hot place
such as under the direct rays of the sun or in a
car in hot weather.
If you do, this may cause distortion, leakage,
overheating, explosion, or fire.
Never allow the battery to come in contact
with water.
If it does, this may cause the battery to rust
or lead to distortion, leakage, overheating,
explosion, or fire.
Never store the battery in a hot and highly
humid environment.
Doing so may cause the performance of the
battery to deteriorate. In certain environments,
this may lead to distortion, leakage,
overheating, explosion, or fire. |
