    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: -40C (-40F) ~ 125C (257F). 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 -30C ~ +60C.
    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.

    Bill Leahy, K0ZL (sk) battery replacement instructions list DigiKey part number P025-ND as an alternative battery. This battery is shown in the photos of his replacement instructions.
    This battery is actually Panasonic BR2330A/FA.
    The FA suffix is the ID designation for a 7 mm and 5 mm solder tab horizontal to the battery with insulation wrap (lime green).
    This battery is rated at 255mAh and fits 35 mm spacing between the PC board connections.
