    just landed a brand new odyssey 34/78 1500 battery for a hundred bucks, local.

    the guy said that the battery was sitting in his garage for a few months (maybe 2-3 months).

    when i checked the battery with the multimeter, it reads 10.6 and later 10.3. seems like its dropping.

    is this normal??? <<< because its been sitting around and "discharging"???

    if so, how can i charge it???

    thank you all.

    no, not installed yet.

    as of now, when i brought it home, i set her on the basement concrete.

    is it bad ju-ju to let it sit on concrete floor? why'd ya ask???

    alright then,

    i'm no battery guru, but regarding my issue of the battery being at roughly "10.3" voltages or so, is that supposed to render the batt "discharged" and "bad"???

    The battery is completely discharged at 10.3 volts. You need to charge it using the standard battery setting on your charger. If you use a trickle setting the battery will not charge. Keep your eye on the voltage meter on the charger. When it gets to 14.4 volts take it off the charger and install it in your Tacoma and drive around for 30 minutes or so. This will allow the alternator to finish the charge.
    The old theory of laying a battery on concrete doesn't pertain to Absorbed Glass Mat batteries, as the acid is held in a sponge like substance in a seperator with each plate. The Odyssey battery is an excellent battery that can be left dicharged for a period of time unlike a SLI battery.
