So I checked my voltmeter on some normal alkaline 1.5v batteries at 10AC setting and was getting over 2v on both of them. Regardless of the accuracy of the readings I should be getting over twice the reading from the 3.6v over the 1.5v batteries correct?

I priced some battery replacements and found some for ~$7. The one in the mobo is a Tadiran 3.6v TL-5151 and the ones I am finding are:

Tadiran 1/2 "AA" Size - 3.6 Volt Lithium:

TL-2150, TL5101, and TL5902

will any of these work? Thanks again!
