Solved: Red flashing power light and a constant beep tone after ...
Perhaps the new battery is unusually depleted or old stock? I''d try leaving the unit plugged in but turned off (so it won''t produce the constant beep tone) with the new battery in place for 24 hours. After that, if you have a DC voltmeter and feel comfortable doing so, disconnect the battery and take a voltage reading.
