    Battery voltage question.

    I have an old Niterider battery holder canister. It holds 5 D cell batteries. I've used it in the past w/ rechargeable 1.2v NIMH. It holds 5 batteries. Would using 5 1.5v Alkaline batteries achieve a 25% overvolt. Are the Alkaline batteries as strong as far as powering the light.

    Thanks

    Stick with the nimh. Alks start at a higher voltage, but have quite high internal resistance and their voltge drops more linearly throughout discharge. Nimh start lower. but the voltage drop is flatter, it then drops off more suddenly at the end of discharge.

    the nimh will have a higher voltage at the 2nd half of discharge.

    Alkalines won't even give higher voltage at the start of discharge if you're running a relatively high power light, due to the high internal resistance - stick to the NiMH.

    Thanks Stu and Cr.

    I knew you all would know the difference.
