Coin-type lithium batteries are often used as the power
supplies for memory backup in various equipment. However
problems with the erasure of valuable data in the memory
due to improper contact between the batteries and
equipment can occur.

are subject to modification without notice. Contact Panasonic for the latest information.

term, select batteries with no terminals or lead wire
connectors.
Select tab terminal-mounted batteries, and solder
the tabs to the battery connection terminals of the
equipment. (See Fig. 1)
When batteries need to be replaced, use a battery
holder (see Fig. 2) or battery with lead wire
connectors (see Fig. 3).
Use of Y-shaped terminals (2-point contact) for
both the (+) and (-) poles as the shape of the
connection terminals in the equipment helps to
achieve a more stable contact. (See Fig. 4)
The contact pressure of the contacts should be no
less than 2 to 10N (approx. 200 to 1000 gf). (See
Fig. 5)
To prevent momentary contact failure of several
milliseconds in the circuit, the use of a tantalum
capacitor, etc. with a capacitance of several
microfarads is effective. (See Fig. 6)
For the connection terminals of the equipment,
use iron or stainless steel with nickel plating at the
very least. Gold-plating is more suitable when the
contact resistance must be reduced.
perspiration (salt), body oil etc. will increase the
surface resistance which may lead to defective
contact.
