TS 430 Memory Battery

[W9GB]

Coin-type lithium batteries (Sanyo; Panasonic) are available in two types:

Poly-carbonmonofluoride lithium (BR series): For uses that require extended reliability and safety.
The BR series batteries are for applications exposed to extended temperature ranges and harsh operating conditions - operational temperature range: -40°C (-40°F) ~ 125°C (257°F). This series has excellent leakage resistance and is commonly found in automotive electric systems; tollway transponders and RFID units.
--
Manganese dioxide lithium (CR series): For uses that require high voltage and strong load pulse characteristics. The CR series batteries have a temperature range of -30ºC ~ +60ºC.
This series is used for high voltage requirements and strong load pulse characteristics. These are commonly found in memory back-up applications (with tab terminals), cameras, watches and calculators.

The specific battery that Kenwood uses (W09-0326-05) is a Sanyo CR2032 battery with solder tabs - Panasonic CR2032/1F2 is equivalent to the Sanyo.
The 1F2 suffix is the ID designation for the 7 mm solder tabs horizontal to the battery and with insulation wrap (yellow).
This battery is rated at 220 mAh and easily fits the 35mm spacing between the PC board connections.

Digi-Key sells the BR version.
