How can I tell if my battery is OK?

    I don't much about electronics.

    I replaced my battery in my TC 2290 and it still doesn't recall presets. The help desk said that possibly the heat from the soldering gun ruined the battery.

    I've got a radio shack multimeter.

    Here's what I did. I put in on AC/DC mode, the black probe on the negative and the red probe on the positive and it read 2.95 mv. It's supposed to be a 3 volt.

    I attached a flashlight battery to the terminals and it lit up.

    Could it possibly not be powerful enough to hold the presets but still work?

    the difference between 2.95 volts and 3 volts shouldn't have made a difference..i don't know what's wrong but it's probably not the voltage.

    I reread his post:

    He said 2.95 mV (millivolt). If it supposed to be 3 volts (and the mV was a typo, not a digital readout), the battery is dead.

    If it's a typo, then send the TC2290 to ME! ;)
