    Question newbie question

    I'm getting a blast boat & got an extra battery - venom 4200 7.2 volt. a friend gave me a wall charger - it states output, 9v dc 200 ma. it has the correct plug for the battery. will this work ok?

    It sounds like you have a 6 cell NiMH/NiCD and a 6 cell NiMH/NiCD charger... so it should work.

    It may take about 24 hours to charge though.
    Whatever it is I just said... I could be wrong.

    how do I know when it's done charging? there's no light on the charger. per other posts on this forum, I've read that the battery gets warm when fully charged - should I go by that?

    Yes; warm = charged.
    Also, I would check voltages after the charge is complete.

    well, it's been 22 hrs & the battery is barely warm - the charger is warmer. i think i'll let it charge the full 24 hrs. if i check voltage, i assume it should be 7.2 volts?

    I would recommend a better charger. Personally, I like to run my cars as often as possible. You can charge your batteries in an hour with a better charger.
    A 6 cell nimh battery will be closer to 9v at full charge.

    1.5 volts x # of cells.

    so, after 24 hrs, then let it sit overnight, per voltmeter, 8 volts - battery is a venom, 6 cell nimh, 4200, 7.2 volt - i will use it in the blast boat - rarely.
