    When charging my NIMH pack why does my charger read around 8.90volts after charging?

    I was just wondering why does a charger indicate that the nimh pack is at 8.90v (around the time the battery is fully charged) when my pack is only a 7.2v pack? I will post a pic later to better explain what I'm trying to ask.

    7.2 is nominal voltage. Charged it should be 8.7V for a six cell (1.45V per cell) ideally. At 1.5V per cell it gives 9V for six cell this is the Max, anything higher then a cell is going bad. I had a old six cell charging to 10.8V lasted about three runs. Then i seen Lipo.

    i charged my one 5000mah pack a couple nights ago and when it was done, it was hot to the touch, is that safe or could i have damaged my pack? Also am i supposed to discharge my packs before i recharge them?

    Not necessary with NiMH packs.
    I know they're having their break there by your brake drums. No, you're not invited.

    Her's a charge graph of NiMH cells:

    You'll typically see 1.5 volts per cell during fast charging, then when the set delta peak is detected and the charger stops or goes into trickle mode, the voltage drops. I let this charge trickle long enough to regain some voltage.

    This is a NiMH thread and forum.
