Rechargeable Button Cells
CARE AND HANDLING
1. Connections and Terminals
Soldering of lead wires directly onto cells can damage
the internal components like the gasket and other parts.
It is recommended that a tag is spotwelded to the cell,
on which lead wires can then be soldered. Never solder
onto cells directly!
2. Parallel Cell Configuration
Parallel charging may produce unpredictable current
distribution into cells. Therefore overcharge and low
performing cells may result.
When designing a battery where paralleling is needed,
please consult us.
3. Contact Terminals
Battery assembly contact materials as well as contacts
in battery holders should have a nickel surface for best
corrosion resistance.
4. Battery Position
For optimum life batteries should be shielded or placed
apart from heat sources.
5. Vented Battery Compartments
Airtight battery compartments are not allowed. Under
abuse conditions cell venting may occur releasing
hydrogen gas. It is therefore necessary for compart-
ments to have an air ventilation.
6. Disassembly
Under no conditions should cells be disassembled.
Cells contain potassium hydroxide electrolyte, which
can cause injury. In the event that the electrolyte gets
on skin or in eyes, immediately flush with water and
seek medical advice.
7. Handling
Do not pull excessively on lead wires or connectors, as
exessive force will cause product damage.
8. Incineration
Do not dispose of cells or batteries in a fire or in
incinerator since rupturing and disassembly may occur.
9. Mixing of Cell Types
Do not put different cells and capacities in the same
battery assembly! The mixed use of NiMH cells with
NiCd cells, primary cells, old and new cells, cells of
different sizes and capacities in one assembly can be
dangerous and lead to either battery damage or poor
performance of the device that it is intended to power.
