1 The radioactive iodine is usually given in pill form, although it can be given in liquid form. 2  Some people have trouble swallowing pills. 3  If you do, tell your doctor in Nuclear Medicine before your treatment.
Shelf Life. While an alkaline battery is reliable, it has a shelf life of about 7 to 10 years. Around that time, the chemicals within the battery become stagnant and no longer produce a chemical reaction to power the battery. Some people believe that placing unused batteries in a freezer extends their shelf life.
It is believed that priming becomes necessary if the voltage drops below 1V/cell. Primary alkaline and lithium batteries can be stored for up to 10 years with only moderate capacity loss. You can store a sealed lead acid battery for up to 2 years. Since all batteries gradually self-discharge over time, it is important to check the voltage and/or specific gravity, and then apply a charge when the battery falls to 70 percent state-of-charge, which reflects 2.07V/cell open circuit or 12.42V for a 12V pack.
