Precautions on use

6. Precautions on use
6-1 Limits on use
Because an accident or malfunction of the SLB could
result in injury or damage to property, NICHICON
requests you confer with NICHICON in advance if you areconsidering using the product in a situation requiring ahigh degree of reliability, such as those indicated below.
(1) Aircraft, (2) spacecraft, (3) generator control
equipment, (4) medical instrument, (5) transport
equipment, (6) traffic signaling device, (7) fire protection,or (8) crime prevention equipment
・ When using the SLB, please design the equipment
based on the delivery specifications. NICHICON isnot liable for any problems that may occur in yourequipment without checking the delivery specifications.
・In addition, NICHICON is not liable for any incidental orindirect damages related to the customer's product thatuses our product.
・Since it is difficult to prevent failures by testing only
individual parts, be sure to perform the necessary
evaluation tests after incorporating the SLB into yourdevice to make sure that no problems may occur.
・ If the SLB does not conform to the specifications,
NICHICON will provide repair and replacement for free,or compensate for the amount equivalent to the sales
price of the subject product.
・If you have any objections or doubts about the contentsof this technical note, please contact NICHICON before
ordering. If you have not contacted Nichicon before
placing the order, NICHICON will assume that you haveaccepted the contents of the delivery specifications.

6-2 Storage conditions
The SLB should be stored in an environment wherecondensation is not present and within the recommended
temperature range for storage (5 to 35°C). The SLB has
a low rate of self-discharge. If the voltage drops below
2.15V, please apply a supplementary charge to 2.4V
across the terminals. If the voltage across the terminals
falls below 2.0V, do not use a supplementary charge, but
contact NICHICON.

6-3 Precautions on settings
1. The SLB has a limited life.
2. A range for the operation and storage of the SLB has
been set. Degradation of its electrical characteristics
increases substantially if the SLB is used intemperatures that exceed the maximum level.
3. If the discharge current is large, a voltage drop occurswhen discharge is initiated. Please confirm the circuit
discharge current and the SLB internal resistancevalues (DCR).

4. When the SLB is connected in series, a voltage
imbalance can cause the voltage on certain cells
to exceed their rated upper or lower voltages. We
recommend the use of overcharge/over-discharge
countermeasures, such as voltage monitoring circuit
devices.
5. The SLB is polarized. Do not apply a reverse voltage.
6. Avoid placing heat generating components in theSLB’s vicinity or on the back surface of the printed
wiring board.
7. When mounting, provide insulation to the contact parts
such as the board.

6-4 Solder mounting
1. The SLB is not compatible with flow mounting or
reflow solder mounting. When mounting, take care to
avoid mounting methods such as solder mounting or
connector mounting in which the main part of the SLB
would exceed the warranted temperature range.
2. When mounting this product, please avoid excessive
mechanical stress, vibration, or pressure, as this could
result in degradation of electrode terminals or electricalcharacteristics.
3. If solder mounting, we recommend mounting underthese conditions.
Solder: Core thread solder (recommended: φ1.2mm)
Solder type: Lead-free solder Sn-3.0Ag-0.5Cu
Soldering temperature: 350°C±10°C
Solder time: Within 5s per terminal
Times soldering: 2 or less per terminal
4. Do not wash after mounting.

6-5 Resin coating
If the SLB is coated with resin, metal corrosion may occur,depending on the coating resin type. The risk also exists:
the terminals or the aluminum case could change shapedue to shrinkage when the resin cures. Please selecta resin that allows the reliability of this product to bemaintained.

6-6 Disassembly
Do not disassemble the SLB, as liquid leaks andaccidents could result.

Precautions on use

6-7 Hazard
Since the chemical components are sealed in the SLB,
its hazard is extremely low. However, if used improperly,
the SLB may be deformed, leak, burst, generate heat,or generate irritating gas or corrosive gas. Take extreme
care when using it.

6-8 Stability and reactivity(1) If two or more SLBs are allowed to touch withoutinsulating the terminals, from each other, there is apossibility of explosion or sudden heat generation due
to a short circuit.
(2) If the SLB is overcharged, heated, or dropped in a fire,the electrolyte may spurt out rapidly.
(3) If the SLB is disassembled, there is a possibility ofsudden heat generation due to a short circuit.

6-11 Others
・ Do not short-circuit the SLB.

Overheating of the cell may cause electrolyte leakage,explosion, or heat generation.
・ Do not apply reverse voltage to the SLB.
Abnormalities may occur inside the SLB, which may
cause leakage, rupture, and heat generation.
・ Do not apply excessive force to the SLB.
If excessive force is applied, the parts may become
damaged, and electric shock, short circuit, or liquidleakage may occur.
・ Do not perform the following tests.
Overcharge test, over discharge test, nail penetration
test, crush test, drop test, chemical resistance test,
high temperature exposure test.
・ The long-term storage performance is still under test.

6-9 Electrolyte leak
The electrolyte of the SLB is flammable. It may irritate theeyes, skin and mucous membranes. Please refer to thefollowing if an electrolyte leak occurs.
・If the electrolyte gets on your skin, immediately washthe skin with soap and lukewarm water. Seek medical
attention immediately if you notice any changes in yourskin or if there is persistent pain.
・If the electrolyte get in your eyes, immediately rinse
your eyes with water for 15 minutes then seek medical
attention immediately.
・ If smoke or fire occurs, extinguish the fire with carbon
dioxide fire extinguisher, powder fire extinguisher, or alarge amount of water.

6-10 Storage
・ Do not allow the terminals to touch each other or makethe terminals touch a conductor.

・ Avoid storing in the following environment.

(A) Environments that are directly exposed to water,or environments with high-temperature and highhumidity, or environments where condensation occurs(B) Environments directly exposed to oil, or environments
filled with oil in a gaseous state.
(C)Environments directly exposed to salt water, orenvironments full of salt.
(D)Environments filled with toxic gases (hydrogen sulfide,sulfite, nitrite, chlorine, bromine, methyl bromide,ammonia, etc.).
(E) Environments expose to direct sunlight, ozone,ultraviolet rays or radiation.
(F) Environments expose to acidic or alkaline solvents.
