>From the 3/21 manual: "The 3/21 meter is powered by two batteries--one 1.3 volt mercury battry and one 22.5 volt dry cell. The mercury battery operates the high range (H) and the dry cell operates the low range (L)......The following replacement batteries or their equivalent should be use: 1.3 volt mercury battery Eveready E-1; 25.5 volt dry battery, Everyeady 412." The Radio Shack numbers are for special order. Since mercury batteries aren't available for sale in the US, these numbers are the closest replacements in alkaline batteries. I have tested them in the meter according to the manual and they meet the requirements of the 3/21 meter. If you have trouble getting them through your local Radio Shack, I can order them for you through my store.
