transportation and general shock. No leakage problem.
UN
transportation test The LIR series of
secondary (rechargeable) lithium button cells gives gives high voltage, long
shelf life, and high energy density in a small cell. Applications include
laptop computers, PDA, IC cards, electric clocks, watches, remote control keys,
cameras, toys, etc.

Quantity pricing is based on one order, one shipment.
Allow time for ocean freight from China for large quantities of lithium
containing cells.
Caution:
(1) Do not short-circuit
(2) Do
not over-discharge , dent, crush, or burn the battery.
(3) The battery
should be removed from the instrument when battery is depleted.
(4) Do not
try to solder directly to the battery, don't put through solder reflow process
.
(5) Do not disassemble the batteries.
(6) Do not use outside
specified temperature range
PowerStream offers these lithium ion
rechargeable coin cells to original equipment manufacturers. We have supplied
many thousands of these cells to many happy customers in the USA, Korea, Japan,
and Europe.
Prices are subject to change, please inquire
for current prices. We carry some stock in the USA, larger quantities 3-6 weeks
delivery time.
Following are examples of solder tabs that have
been made. Even though surface mount tabs are available, these cells will be
damaged if put through a surface mount reflow process due to the high
temperatures involved. For a complete list of
pin configurations click here.
