Posessed HP-71

Quote:" lithium AA's into my HP-71"

I would be impressed if you managed to get 4 L-91 cells into a 71b. The voltage drop off for AAA / L92 has a very sharp voltage drop off near end-of-life, and could possibly cause brown-out or under-voltage conditions.

At 10ma constant current discharge while running (room temp 21 C), the capacity (mAh) of AAA Lithium is the identical as AAA Alkaline, which might not justify the extra cost?

Lithium really excels at low temperatures, high current, or burst current loads (camera flash).
